[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telephone device that reproduces music of music information composed of a plurality of tracks, and in particular, prevents synchronization loss when reproducing music information included in each track as much as possible, and replays it.
The present invention relates to a telephone device that prevents a user or the like from feeling a sense of incongruity that a synchronization error has occurred in generated music information.
[0002]
[Prior art]
Recently, a telephone device having a function of informing with a melody as a holding tone or the like is becoming popular. In the case of such a telephone device, the user stores in advance desired melody data in a memory in the telephone device by a predetermined operation, and when the hold button is turned on, the set melody data is reproduced and communication is performed. Sending to the other party.
[0003]
[Problems to be solved by the invention]
However, in recent telephone devices, the user side of the telephone device composes the music on hold and uses the composed melody data stored in the memory in the telephone device, or purchases a commercially available melody, The melody data may be stored in a memory in the telephone device and used, but the melody data composed of a plurality of tracks may be used.
In such a case, the melody data is sent as a hold tone to the communication partner via the communication line. However, when the melody data is to be reproduced in accordance with the musical score, the resolution that allows performance control (interruption to the CPU) (Timing period) is limited, and depending on the type of tempo, it may not be possible to perform correctly.
For example, in the case of a telephone device attached to a facsimile machine, a DSP (Digtal Signal Processor) function installed in the facsimile modem is used or a dedicated memory is used.
If music such as music on hold is played by software processing by a microcomputer using a loader sound source, etc., the cycle of the timing for interrupting the CPU to control playback, the clock frequency Etc., the resolution is determined.
The present invention has been made in order to solve the above-described conventional problems, and prevents music information included in each track from being out of synchronization as much as possible when playing music information composed of a plurality of tracks. Accordingly, an object of the present invention is to provide an excellent telephone device that does not cause a user or the like to feel a sense of incongruity that a synchronization shift has occurred in music information to be reproduced.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, according to the telephone device according to claim 1, the telephone device can reproduce music information composed of a plurality of tracks by a reproducing means, and the music information is preset. In the case of tempo, the divided values obtained by dividing the time lengths of notes and rests of all lengths included in each track by the resolution that can be reproduced by the playback means are the notes and rests of all lengths. Adjustment In number A determination means for determining whether or not there is a division value; In number If the determination means determines that the tempo cannot be reproduced by the reproduction means, the division value is adjusted for all lengths of notes and rests so that the reproduction means can reproduce. Number and Control means for changing the tempo is provided.
[0005]
Specifically, for example, a main melody is stored in one track among a plurality of tracks, whereas a sub melody is stored in another track, for example, so that the main melody and the sub melody are synchronized. It is necessary to play music information. Therefore, the reproducible resolution (interrupt timing period to the CPU) is, for example, 1/60 seconds, and the designated tempo is, for example, “69.2307692” (there is no tune that actually has such a tempo designated) It seems that this is assumed for ease of understanding, but here it represents the tempo of “3600 divided by 52”, but here it is 7 digits after the decimal point. (The same applies hereinafter.) It is assumed that the note data included in each track is, for example, a quarter note, an eighth note, a 32nd note, and a 64th note (notes and rests). Can be considered the same, so here we will describe notes, but the same applies to rests, and so on), and these quarter notes, eighth notes, thirty-second notes and sixty-fourth notes The time length and divided by 1/60-second "52", "26", a "6.5" and "3.25", Sei all Number and Cannot be expressed. For this reason, a 32nd note or a 64th note that does not become an integral multiple of 1/60 seconds of resolution cannot be accurately reproduced, and a synchronization shift occurs. That is, when the tempo is “69.2307692”, a quarter note can be represented by “52” pieces of resolution that can be reproduced, whereas a 64th note is reproduced. However, since the resolution of “6.5” is not the timing at which an interrupt is executed, it cannot be accurately reproduced.
Therefore, the tempo “69.2307692” is changed to the tempo “75”, and the note data included in the track is reproduced. Then, when the tempo is “75”, the time length of these quarter notes, eighth notes, thirty second notes, and sixty fourth notes is divided by 1/60 seconds to obtain quarter notes, eighth notes, thirty second notes and The 64th note is “48”, “24”, “6”, and “3” as multiples of the resolution that can be reproduced, and can be expressed as an integral multiple of the resolution that can be reproduced. Even if is 1/60 seconds, 32nd notes or 64th notes can be accurately reproduced.
[0006]
On the other hand, when considering a quarter note played in one minute, when the specified tempo is “90”, dividing 60 seconds by 90 gives a quarter note time length of 2/3 seconds. When the resolution that can be reproduced is 1/60 seconds, the time length of 2/4 seconds of a quarter note is divided by 1/60 seconds to be “40”. In other words, when the tempo is “90”, it can be expressed by “40” sentences with resolution that can be played back by a quarter note time length of 2/3 seconds, so that a quarter note is recorded on multiple tracks. In the case where only music data is included, there is no synchronization shift when music information included in each track is reproduced.
[0007]
Therefore, according to the telephone device according to the first aspect, the determination means calculates the time lengths of the notes and rests in the case of the preset tempo, and calculates the calculated time lengths of the notes and rests. By using this, it can be determined whether or not the music information can be reproduced by the reproduction means at a preset tempo. Specifically, if the calculated time lengths of notes and rests can be expressed as integer multiples of the reproducible resolution, there is no need to change the tempo. On the other hand, when the calculated note and rest time length cannot be expressed as an integral multiple of the reproducible resolution, the tempo is changed, so when playing music information music composed of multiple tracks, Even if there is a change in the tempo, it is possible to prevent the synchronization of music information included in each track or to prevent it as much as possible. As a result, the user of the telephone device does not feel uncomfortable that the music information to be reproduced is out of sync.
[0008]
According to a second aspect of the present invention, in the telephone device according to the first aspect, the control means changes to a tempo that can be reproduced by the reproducing means and that is closest to a preset tempo. It is characterized by doing.
[0009]
Specifically, the reproducible resolution is, for example, 1/60 seconds, the specified tempo is, for example, “69.2307692”, and the note data included in each track is, for example, a quarter note, an eighth note, Assuming that the notes are the 32nd note and the 64th note, the 4th note, the 8th note, the 32nd note and the 64th note become “32”, “16”, “6.5” and “3.25”. When a 32nd note and a 64th note that cannot be expressed as an integral multiple of the reproducible resolution are played, a synchronization error occurs.
Here, for example, when the tempo “112.5” is adopted, the time lengths of these quarter notes, eighth notes, thirty second notes, and sixty fourth notes are divided by 1/60 seconds to obtain “32”, “16”, “4” or “2”, which can be expressed as an integral multiple of the reproducible resolution, and can accurately reproduce 32nd note or 64th note. However, if the tempo “69.2307692” is changed to the tempo “112.5”, the difference in tempo is too large, so the tempo “69.2307692” is changed to the tempo closest to the preset tempo, for example. It is desirable to change the tempo to “75”.
According to the telephone device of the second aspect, the control unit changes the tempo that can be reproduced by the reproduction unit and is the closest to the preset tempo. On the other hand, it is possible to prevent synchronization loss when music information included in each track is reproduced, or to prevent it as much as possible. As a result, the user of the telephone device does not feel the tempo change so much and does not feel uncomfortable that the music information to be reproduced is out of sync.
[0010]
According to a third aspect of the present invention, in the telephone device according to the second aspect, the control means can play back the notes and rests of all lengths included in each track of the music information. It is characterized by changing to.
[0011]
Specifically, the reproducible resolution is, for example, 1/60 seconds, the specified tempo is, for example, “69.2307692”, and all length notes included in each track are, for example, quarter notes. , 8th note, 32nd note, and 64th note, according to the calculation method described above, these 4th note, 8th note, 32nd note and 64th note are "52", "26 ”,“ 6.5 ”, and“ 3.25 ”, and a synchronization error occurs when playing 32nd and 64th notes that cannot be expressed as an integral multiple of the reproducible resolution.
Therefore, if the notes of all lengths included in each track of the music information are, for example, quarter notes, eighth notes, thirty second notes and sixty fourth notes, the tempo “69.2307692” is changed to the tempo “75”. Then, the music information music included in the track is reproduced. Here, when the tempo is “75”, these quarter notes, eighth notes, 32nd notes and 64th notes are “48”, “24”, “6” and “3”, and are reproduced. It can be expressed as an integral multiple of the resolution that can be reproduced, and 32nd note or 64th note can be reproduced accurately.
According to such a telephone device according to claim 3, the control means changes to a tempo that can express notes and rests of all lengths included in each track of the music information. When the music of the music information configured from the above is reproduced, the synchronization of the music information included in each track can be prevented even if there is a slight change in tempo. As a result, it is possible to avoid a sense of incongruity that the music information to be reproduced is out of synchronization with respect to the notes and rests of all lengths included in each track.
[0012]
According to a fourth aspect of the present invention, in the telephone device according to the second aspect, the control means can reproduce a predetermined length of notes and rests included in each track of the music information. It is characterized by changing to.
Specifically, the reproducible resolution is, for example, 1/60 seconds, the specified tempo is, for example, “69.2307692”, and the note data included in each track is, for example, a quarter note, an eighth note, Assuming that the notes are the 32nd note and the 64th note, the 4th note, the 8th note, the 32nd note and the 64th note become “52”, “26”, “6.5” and “3.25”. When a 32nd note and a 64th note that cannot be expressed as an integral multiple of the reproducible resolution are played, a synchronization error occurs. Therefore, the tempo “69.2307692” is changed to the tempo “64.2857143” (a value obtained by dividing 3600 by 56), and the quarter note, eighth note, thirty second note, and sixty fourth note of the note data included in the track , The quarter note, eighth note, 32nd note and 64th note are “56”, “28”, “7” and “3.5” as multiples of the resolution that can be reproduced. Thus, quarter notes, eighth notes, and thirty-second notes can also be expressed as integer multiples of the reproducible resolution, and quarter notes, eighth notes, and thirty-second notes can be accurately reproduced.
However, a 64th note cannot be expressed as an integral multiple of the resolution that can be reproduced, and a 64th note cannot be played accurately with a resolution of 1/60 seconds. However, when there is no 64th note in the note data included in each track (that is, when it is composed of a quarter note, an eighth note, and a 32nd note), the tempo “64.2857143” may be adopted. Further, even if the note data included in each track is, for example, a quarter note, an eighth note, a 32nd note, and a 64th note, if it is recognized that the 64th note cannot be played correctly, the tempo “64. 2857143 "may be adopted.
According to the telephone device of the fourth aspect, the control means includes notes of a predetermined length included in each track of the music information (that is, quarter notes, eighth notes excluding 64th notes, 32 minutes). (Note of a predetermined length of notes) and a tempo that can express rests, so when playing music information music composed of multiple tracks, even if there is a slight tempo change It is possible to prevent synchronization deviation of music information included in each track as much as possible. As a result, the user of the telephone device does not feel a sense of incongruity that the music information to be reproduced is out of sync with the notes and rests of a predetermined length included in each track.
[0013]
According to a fifth aspect of the present invention, in the telephone device according to any one of the first to fourth aspects, the music information is held to a communication partner via a telephone line by operating a holding member. It is transmitted as sound.
According to such a telephone device according to claim 5, by operating the holding member, it is possible to send music information as a holding sound to the communication partner via the telephone line. When the music of the music information that has been recorded is reproduced as a holding tone, it is possible to prevent or prevent the synchronization of music information included in each track as much as possible. As a result, the user of the telephone device does not feel uncomfortable that the music information to be reproduced is out of sync and the communication partner can easily listen to the music (melody).
[0014]
According to a sixth aspect of the present invention, in the telephone device according to any one of the first to fifth aspects, the music information is reproduced as a ring tone.
According to the telephone device of the sixth aspect, music information can be reproduced. Therefore, when music of music information composed of a plurality of tracks is reproduced as a ringtone, music included in each track Information synchronization shift can be prevented or can be prevented as much as possible. As a result, the user or the like of the telephone device does not feel uncomfortable that the music information to be reproduced is out of synchronization, and the music (melody) can be easily heard.
[0015]

The hold sound storage button 16a, the hold sound playback button 16b, and the hold sound sending button 16c function as a holding member that is used when the user of the telephone device 1 sends a holding sound to the other party's telephone device.
[0019]
Next, the control system of the telephone device 1 will be described with reference to FIG. FIG. 3 is a block diagram showing a control system of the telephone device 1 according to the present embodiment. In FIG. 3, the control system of the telephone device 1 has a control unit 17 having a CPU as a core, and performs integrated control of the telephone function part and the facsimile function part. The control unit 17 is connected to an operation panel unit 5 having a liquid crystal display (LCD) 6 and is connected to a ROM 18 as a read-only nonvolatile memory, or a volatile memory such as a RAM or a rewritable memory. A temporary memory 19 such as a flash memory which is a non-volatile memory is connected.
The control unit 17 is also connected with a speaker 23 for voice output, and the temporary storage memory 19 or the holding tone data memory 19A is operated by the operation of the voice playback function unit (melody playback function unit) 17a of the control unit 17. The music data composed of a plurality of tracks stored in is output as sound.
[0020]
In this case, the voice reproduction function unit 17a reproduces music (melody) by using, for example, MIDI (Musical Instrument Digital Interface) data as music (melody) information data. As data of the MIDI (MIDI is a registered trademark), MIDI data for the main melody as the first track and MIDI data for the secondary melody as the second track are used. The midi data for each track includes at least instrument data, tempo data, note data, scale data, and the like.
In this case, the instrument data is data for designating an instrument such as a bass guitar, an acoustic piano, a lead guitar, a bass guitar, or a drum, and the instrument data includes data for designating the tone of these instruments. include. The note data includes note data such as full notes, half notes, quarter notes, eighth notes, thirty-second notes, and sixty-fourth notes, as shown in FIG. The tempo data is normally specified in the range of “60” to “180”, but most of them are specified by integer values such as “75” and “90”. That is, as shown in FIG. 6, a number such as “64.2857143”, “112.5”, “128.571429” (a value obtained by dividing 3600 by 28) may be specified as the tempo. Absent. FIG. 6 is a diagram showing a table used when the telephone device 1 of this embodiment performs a process of changing the tempo of music information notes, and is a full note, a half note, a quarter note, In order to reproduce 16th notes, 8th notes, 32nd notes, and 64th notes, a multiple of the resolution (interrupt timing period to the CPU) that can be reproduced is shown. In FIG. 6, when the reproducible resolution is set to 1/60 seconds, for example, and the tempo is “64.2857143”, all notes, half notes, quarter notes, and eight minutes included in each track “224”, “112”, “56”, “28”, “28”, “14”, “7”, and “3.5” as multiples of notes, sixteenth notes, thirty-second notes, and sixty-fourth notes It becomes. In this case, for all rests, 2-minute rests, 4-minute rests, 8-minute rests, 16-minute rests, 32-minute rests, and 64-minute rests, all notes, half-notes, quarter-notes, 8 It can be expressed in multiples similar to half notes, sixteenth notes, thirty second notes, and sixty fourth notes.
[0021]
Similarly, when the reproducible resolution is set to 1/60 seconds, for example, and the specified tempo is “75”, all notes, half notes, quarter notes, and eighth notes included in each track , 16th note, 32nd note, and 64th note are “192”, “48”, “24”, “24”, “12”, “6”, and “3” as multiples of resolution that can be reproduced. It becomes. In addition, when the reproducible resolution is set to 1/60 seconds, for example, and the specified tempo is “90”, all notes, half notes, quarter notes, eighth notes, The sixteenth note, thirty-second note, and sixty-fourth note are “160”, “80”, “40”, “20”, “10”, “5”, and “2.5” as multiples of the resolution that can be reproduced. The same applies to “112.5” and the like.
[0022]
Here, an outline of sound reproduction by the action of the sound reproduction function unit 17a will be described with reference to FIG. FIG. 7 is a schematic diagram illustrating a process in which the telephone device 1 according to the present embodiment reproduces a musical note in music information. When the main melody as the first track in FIG. 7A and the sub melody as the second track in FIG. 7B are played, the first track and the second track are each bar. It is necessary to synchronize for each note of the music, and as a result, the performance time of the music information of the main melody and the music information of the sub melody is the same. When the reproducible resolution (interrupt timing period to the CPU) T is 1/60 seconds, for example, the note and rest times can be set in integer multiples of 1/60 seconds. Specifically, if there is an eighth note in the first track of FIG. 7A, and the designated tempo is “75”, the length is set to 24/60 seconds, and FIG. If there is a sixteenth note on the second track in b), the length is set to 12/60 seconds. Accordingly, the eighth track A1, A2 is played on the first track of FIG. 7A, and the sixteenth notes B1, B2, B3 are played on the second track of FIG. 7B. When playing in synchronization, the first eighth note A1 and the second eighth note A2 of the first track in FIG. 7A and the sixteenth note B1 of the second track in FIG. If it is necessary to synchronize with the third sixteenth note B3 and it cannot be expressed in an integral multiple of 1/60 seconds, accurate synchronization cannot be achieved.
[0023]
In this case, the control unit 17 includes a note detection unit 17b that can detect the tempo information of the entire song, the notes of the main melody music information, and the notes of the sub melody music information. When the note detection unit 17b grasps the note of the music information and can determine whether or not the music information can be expressed at a predetermined tempo, it is determined that the tempo cannot be expressed. By changing the tempo, the control unit 17 can prevent the music information included in each track from being out of synchronization when playing music information composed of a plurality of tracks.
Specifically, considering a quarter note played in one minute, when the tempo is “90”, dividing the 60 seconds by the tempo “90”, the time length of the quarter note becomes 2/3 seconds, When the reproducible resolution is 1/60 seconds, the time length of 2/3 seconds of a quarter note is divided by 1/60 seconds of the reproducible resolution to be “40”. That is, when the tempo is “90”, a quarter note having a length of 2/3 second can be expressed with “40” resolution that can be reproduced.
[0024]
The time length of the quarter note is half of the time length of the half note, and the time length of the half note is “80”. The time length of an eighth note is half of that of a quarter note, and the time length of an eighth note is “20”. The following also applies to “all notes, 16th notes, 32nd notes and 64th notes”, etc. 6 is written.
Similarly, when the tempo is “75”, dividing 60 seconds by 75 results in a quarter note time length of 0.8 seconds, but when the reproducible resolution is 1/60 seconds, 4 minutes Dividing the note time length of 0.8 seconds by 1/60 second of the reproducible resolution gives “48”. That is, when the tempo is “75”, the time length of a quarter note having a length of 0.8 seconds can be expressed by “48” resolutions that can be reproduced. As a result, the half note is “96”, the eighth note is “24”, and “all notes, sixteenth notes, thirty-second notes, and sixty-fourth notes” and the like are also shown in FIG. It is.
As a result, when the music information notes of the first track and the second track are composed of integral multiples of the reproducible resolution T, the notes can be accurately played with a predetermined length. And, when music information composed of the second track is reproduced, a synchronization error does not occur.
[0025]
Of course, in the case of general music, tempos other than “64.2857143”, “75”, “90”, “112.5”, “128.571429”, “150” and “180” are naturally used. (Rather, there are many other cases), and those may not be an integral multiple of the resolution T that can be reproduced when the above calculation method is used.
For example, if the tempo is “69.2307692” (as described above, it is unlikely that a tempo of such a value will be specified, but this is assumed here for ease of understanding). When the note data included in each track is, for example, a quarter note, an eighth note, a 32nd note, and a 64th note, and the reproducible resolution is 1/60 seconds, these quarter notes, 8 minutes The notes, 16th notes, 32nd notes, and 64th notes are “52”, “26”, “6.5”, and “3.25” as multiples of the resolution that can be reproduced. For this reason, a 32nd note or a 64th note cannot be expressed as an integral multiple of the resolution T that can be reproduced, and therefore a synchronization shift occurs when music information included in each track is reproduced. Therefore, the tempo “69.2307692” is changed to, for example, the tempo “75”.
[0026]
Then, when the tempo is “75”, assuming that the note data included in each track is, for example, a quarter note, an eighth note, a 32nd note, and a 64th note, a quarter note, an eighth note, 32 The half note and the 64th note are “48”, “24”, “6”, and “3” as multiples of the resolution that can be played back, and the 32nd note and the 64th note can also be played back. Since it can be expressed as an integral multiple of the possible resolution T, there is no synchronization shift when music information contained in each track is reproduced. In this way, the control unit 17 functioning as a determination unit calculates the time lengths of notes and rests in the case of a preset tempo, and is an integer multiple of the resolution capable of reproducing the time lengths of the notes and rests. Therefore, it is possible to detect a synchronization error when music information included in each track is reproduced.
[0027]
Here, the ROM 18 stores a call control program which is a telephone function part of the telephone device 1, various function control programs inputted from the panel unit 5, and a reading operation and recording operation program which are facsimile function parts. Yes. Further, the ROM 18 stores various basic operation control programs such as line switching control, as well as a processing program for changing the tempo of music information as necessary.
In addition, the temporary storage memory 19 has a holding sound data memory 19 </ b> A for storing a holding sound to be transmitted on the external line 25. The control unit 17 is connected to a modem 30 that performs modulation / demodulation for facsimile communication. In cooperation with the modem 30, the control unit 17 functions as a detection unit that detects a communication control signal, or is sent from a communication partner. The communication control signal is detected, or vice versa.
[0028]
The control unit 17 is connected to an NCU (Network Control Unit) 24, and the NCU 24 is connected to the receiver 10 and the FAX unit 21 via internal lines 27 and 28 and a modem 30. The control unit 17 can input a communication control signal or the like input from the external line 25 (telephone line) via the NCU 24 via the modem 30 or directly via the internal line 26, or the internal line. The communication control signal and the like can be output to the external line 25 through the NCU 24 via the modem 30 via the modem 26. In this case, the connection destination of the telephone device 1 via the external line 25 is, for example, connected to a service company that provides music (melody) distribution services or the like, or the Internet (computer networks are connected to each other) When a contract is made with a service company (provider) connected to a global network, etc., music (melody) data can be received through the Internet by connecting to the access point.
[0029]
In addition, the control unit 17 outputs a voice signal or the like input from the external line 25 via the NCU 24 to the receiver 10 or outputs a voice signal or the like input from the receiver 10 to the external line 25 via the NCU 24. As such, the NCU 24 can be controlled. Further, the control unit 17 demodulates image data or the like input from the external line 25 via the NCU 24 by the modem 30 and outputs the demodulated data to the FAX unit 21, or input from the FAX unit 21 via the NCU 24 to the modem 30. The NCU 24 can be controlled so as to output the image data and the like modulated by the above to the external line 25.
Here, the handset 10 is for making a call with the other party. The FAX unit 21 transmits and receives FAX data. The FAX unit 21 includes a reading scanner (not shown) for reading characters, graphics, and the like of a document fed from the paper stacker 7 into the apparatus main body 2 and outputting image data and the like to the FAX unit 21. A reading unit 20 is connected. Further, the FAX unit 21 is connected with a recording unit 22 including a print head (not shown) for printing image data received via the external line 25, the internal line 28, the modem 30 and the like on a recording sheet. .
[0030]
As a result, when the control unit 17 confirms the incoming call from the external line 25, a ringing tone sounds. When the handset 10 is off-hooked, the NCU 24 can be controlled to establish a voice call with the calling party. When the call is put on hold, if the hold sound sending button 16c on the operation unit panel 5 is pressed, the control unit 17 having the voice reproduction function unit 17a can store a melody or the like indicating the hold state stored in the hold sound data memory 19A. The data is reproduced as voice, sent to the external line 25 via the internal line 26 and put on hold, and a melody or the like can be confirmed also on the receiver 10 and the speaker 23.
Further, for example, when a communication control signal such as a CNG signal is detected, in the telephone device 1, the control unit 17 that detects the communication control signal in cooperation with the modem 30 controls the NCU 24 and the modem 30. The FAX unit 21 establishes FAX reception. Thereafter, when facsimile data from the calling side arrives, the image data received by the FAX unit 21 is temporarily stored in the memory (temporary storage memory 19A), or is recorded by the recording unit 22 simultaneously with reception. . Further, in the telephone device 1 having a function of automatically transmitting a communication control signal such as a CNG signal, for example, the control unit 17 controls the NCU 24 and the modem 30 to transmit the communication control signal, whereby the FAX unit 21 is transmitted. Establishes a FAX transmission at Thereafter, the control unit 17 outputs the image data and the like input from the reading unit 20 to the external line 25 via the modem 30 and the NCU 24.
[0031]
Next, the operation when music (melody) data is stored in the hold sound data memory 19A as a hold sound will be described with reference to FIG. FIG. 4 is a flowchart showing a process of storing music (melody) data as a holding tone in the memory 19A according to the present embodiment. In this case, for example, if a contract is made with a company that distributes music (melody) data or a service company (provider) that is connected to the Internet, the music (melody) data is transferred to the external line 25 through the Internet. The music (melody) data is stored in the temporary storage memory 19 under the control of the control unit 17.
[0032]
In step (hereinafter abbreviated as S) 1, the control unit 17 determines whether or not the music is in the on-hold music storage state. This determination is made by the control unit 17 detecting whether or not the hold sound storage button 16a is pressed. If the hold sound storage button 16a is not pressed and is not in the hold sound storage state (S1: NO), the control unit 17 returns to the standby state.
On the other hand, if the hold sound storage button 16a is pressed and the hold sound is stored (S1: YES), the control unit 17 performs a storing operation for storing the hold sound in the hold sound data memory 19A (S2). Specifically, the music (melody) data stored in the temporary storage memory 19 is played by pressing the music-on-hold playback button 16b (in this playback state, the outline of the image of the song may be known for the time being). Therefore, regardless of the designated tempo, it is always played at a constant tempo, for example, “75”.) Therefore, a user who listens to music (melody) presses the hold tone storage button 16a to A part of the music (melody) data stored in the temporary storage memory 19 is stored in the holding sound data memory 19A as a holding sound.
Then, the control unit 17 determines whether or not the hold sound storage state is released (S3). This determination can be made by the control unit 17 detecting whether or not the hold sound storage button 16a is pressed again. Here, if the user who listens to music (melody) presses the hold sound storage button 16a again and does not cancel the hold sound storage state (S3: NO), the control unit 17 returns to the standby state. If the hold sound storage button 16a is not pressed again, the control unit 17 returns to S2 and continues the storage operation.
[0033]
Next, an operation for changing the tempo of music (melody) as a holding tone will be described with reference to FIG. FIG. 5 is a flowchart when processing for changing the tempo of the music information notes of the present embodiment is performed.
In S <b> 11, the control unit 17 determines whether or not the hold sound detection state. This determination is made by the control unit 17 detecting whether or not both the hold sound storage button 16a and the hold sound transmission button 16c are pressed simultaneously. Here, if both the hold sound storage button 16a and the hold sound sending button 16c are not pressed simultaneously and are not in the hold sound detection state (S11: NO), the control unit 17 returns to the standby state.
On the contrary, if the user presses both the hold sound storage button 16a and the hold sound transmission button 16c at the same time and is in the hold sound reproduction state (S11: YES), the control unit 17 stores the hold sound data, An operation of reading out and detecting from the music on hold data memory 19A is performed (S12). In this case, the control unit 17 uses the note control unit 17b to detect the tempo information of the entire song in the midi data, the note data of a plurality of tracks, and the like, and expresses it with a preset (designated) tempo. It is possible to determine whether or not If the control unit 17 determines that the music information cannot be expressed with a preset tempo (S13: NO), the control unit 17 changes the tempo (S14). In addition, when the control unit 17 determines that the music information can be expressed by a preset tempo (S13: YES), the control unit 17 ends.
[0034]
Here, a specific example of changing the tempo will be described. In this case, the control unit 17 as a playback unit adopts a mode in which the tempo can be played back by the audio playback function unit 17a and is changed to a tempo closest to a preset tempo.
When the reproducible resolution is 1/60 seconds, for example, the specified tempo is “69.2307692”, and the note data included in each track differs depending on the music to be played. For example, assuming a quarter note, an eighth note, a 32nd note, and a 64th note, the quarter note, the eighth note, the 32nd note, and the 64th note are expressed as a multiple of the resolution that can be reproduced. 52 ”,“ 26 ”,“ 6.5 ”, and“ 3.25 ”. For this reason, a synchronization error occurs when playing 32nd and 64th notes that do not become an integral multiple of the resolution T that can be reproduced. Here, when the tempo “69.2307692” is changed to, for example, the tempo “112.5”, for these quarter notes, eighth notes, thirty second notes, and sixty fourth notes, “32”, “16”, “4” ”Or“ 2 ”, which can be expressed as an integral multiple of the reproducible resolution T, so that even 32nd or 64th notes can be accurately reproduced.
However, if tempo “69.2307692” is changed to tempo “112.5”, ten
The difference between the tempo “69.2307692” and the tempo “112.5” is too large, which makes the telephone device user feel uncomfortable. Therefore, it is desirable that the control unit 17 changes the tempo “69.2307692” to, for example, the tempo “75” so as to change the tempo to be the closest to the preset tempo.
Here, when the tempo is “75”, these quarter notes, eighth notes, thirty second notes, and sixty fourth notes are “48”, “24”, “6”, and “3” as multiples of resolution that can be reproduced. It can be expressed as an integral multiple of the resolution T that can be reproduced, and a 32nd note or a 64th note can be reproduced accurately.
Accordingly, the control unit 17 changes the tempo that can be reproduced by the audio reproduction function unit 17a to the tempo closest to the preset tempo, so that it is included in each track while minimizing the tempo change. Can be prevented from being out of sync when playing music information. Of course, in addition to changing the tempo “69.2307692” to, for example, the tempo “75”, the tempo “69.2307692” may be changed to, for example, the tempo “64.2857143”. Therefore, the tempo “69.2307692” may be changed to any tempo.
[0035]
Next, another specific example of changing the tempo will be described. In this case, the control unit 17 stores all length-length notes included in each track of the music information (when all the notes are composed of, for example, quarter notes, eighth notes, thirty-second notes, and sixty-fourth notes), A mode of changing to a tempo that can be expressed is adopted. Specifically, the reproducible resolution is, for example, 1/60 seconds, the specified tempo is, for example, “69.2307692”, and all length notes included in each track are, for example, quarter notes. , 8th note, 32nd note, and 64th note, the time lengths of these notes are “52”, “26”, “6.5” and “3.25”. For this reason, a synchronization error occurs when playing 32nd and 64th notes that do not become an integral multiple of the resolution T that can be reproduced.
Thereby, when the notes of all lengths included in each track of the music information are, for example, a quarter note, an eighth note, a 32nd note, and a 64th note, the control unit 17 sets the tempo “69.2307692”. Then, the tempo is changed to “75” and the music information included in the track is reproduced. Here, when the tempo is “75”, the time lengths of these quarter notes, eighth notes, 32nd notes and 64th notes are “48”, “24”, “6” and “3”, It can be expressed as an integral multiple of the resolution T that can be reproduced, and 32nd note or 64th note can be reproduced accurately.
In this way, the control unit 17 expresses notes of all lengths included in each track of music information (when all the notes are composed of, for example, quarter notes, eighth notes, thirty-second notes, and sixty-fourth notes). Therefore, when playing music information composed of multiple tracks, the music information contained in each track is prevented from being out of sync even when there is a slight change in tempo. Can do.
[0036]
Next, another specific example of changing the tempo will be described. In this case, a mode is adopted in which the control unit 17 changes to a tempo that can express a note of a predetermined length included in each track of music information. Specifically, the reproducible resolution is, for example, 1/60 seconds, the specified tempo is, for example, “69.2307692”, and the note data included in each track is, for example, a quarter note, an eighth note, Assuming that it is a 32nd note and a 64th note, when the 32nd note and the 64th note, which do not become an integral multiple of the resolution T that can be reproduced, are played, a synchronization shift occurs as described above. In this case, the control unit 17 changes the tempo “69.2307692” to the tempo “64.2857143”, and reproduces the quarter note, eighth note, thirty second note, and sixty fourth note of the note data included in the track. To do.
Then, the time lengths of these quarter notes, eighth notes, thirty-second notes and sixty-fourth notes are “56”, “28”, “7” and “3.5”, and the quarter notes, 8 The half note and the 32nd note can be expressed as an integral multiple of the resolution T that can be reproduced, and the resolution is 1/6.
It is possible to accurately reproduce quarter notes, eighth notes and thirty-second notes in 0 seconds. However, a 64th note cannot be expressed as an integer multiple of the resolution T that can be reproduced, and a 64th note cannot be accurately reproduced with a resolution of 1/60 seconds. However, when there is no 64th note in the note data included in each track (that is, when it is composed of a quarter note, an eighth note, and a 32nd note), the tempo “64.2857143” may be adopted. However, even if the note data included in each track is, for example, a quarter note, an eighth note, a 32nd note, and a 64th note, it is accepted that the 64th note cannot be reproduced accurately (at any interrupt timing). Tempo “64.2857143” may be adopted.
[0037]
As described above, the control unit 17 can express notes and rests of a predetermined length included in each track of the music information (that is, quarter notes, eighth notes, and 32nd notes excluding the 64th note). Since the tempo is changed to a possible tempo, when reproducing music information composed of a plurality of tracks, the tempo change can be made as small as possible to prevent synchronization deviation of the music information contained in each track as much as possible.
And the control part 17 displays the display to the effect of changing the tempo of music information on the liquid crystal display 6 as needed, and the control part 17 returns to a standby state.
In this way, a person who has received a warning that the tempo of the music information note is to be changed by the display on the liquid crystal display 6 may not want to change the tempo. Using the music, the storage operation shown in FIG. 4 may be performed again, and the mode of FIG. 5 may be performed again.
Note that when a tempo other than the tempo shown in FIG. 6 is specified (in fact, such a possibility is high), not only 32nd notes and 64th notes but also all notes are expressed. In such a case, the tempo is changed to one of the tempos shown in FIG.
For example, when only a note having a longer playback time than a sixteenth note is included in the track, the tempo is “60” (the time length of the sixteenth note is “15”), “69.2307692” (16 The time length of the half note is “13”, the exact tempo is 3600 divided by 52), “81.181818” (the time length of the 16th note is “11”, and the exact tempo is 3600 divided by 44 (Numerical value) or “100” (the time length of a sixteenth note is “9”). However, since these tempos are similar to those in FIG. Any one of 6 tempos can be substituted.
[0038]
As described above in detail, according to the telephone device 1 of the present embodiment, it is determined whether or not music information composed of a plurality of tracks can be expressed at a preset tempo (S13). When it is determined that it cannot be expressed (S13: NO), the control unit 17 changes the tempo of the music information (S14), so that it is included in each track when playing music of music information composed of a plurality of tracks. Synchronization of music information to be recorded can be prevented, or can be prevented as much as possible. As a result, the user of the telephone device 1 does not feel uncomfortable that the music information to be reproduced is out of sync.
[0039]
Note that the present invention is not limited to the present embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, when determining whether or not the playback means can play back at a preset tempo, the hold sound is output at a constant tempo unrelated to the preset tempo. In the reproduced state, the control unit 17 determines whether or not it can be expressed at a preset tempo. For example, a user of a telephone device or the like can obtain information through a music data distribution service company or the Internet. When the melody data is downloaded for each song, it may be determined whether or not to change the tempo immediately, or a mode in which the tempo is changed after all the melody is downloaded to the memory may be adopted. Also, the music information may be a song, vocal music, instrumental music, room music, orchestral music, or the like.
[0040]
In the above-described embodiment, the tempo is changed when it is determined that the music information of the music on hold is a tempo that cannot be expressed by a preset tempo. However, the present invention is not necessarily limited to this aspect. Absent. For example, it is possible to adopt a mode in which the tempo is changed when it is determined that the music information of the ringtone and other sounds cannot be expressed by a preset tempo.
