Description

  The present invention relates to a karaoke apparatus that provides a karaoke music sound reproduction service.

  As a karaoke piece apparatus that provides a user with a karaoke piece sound reproduction service, for example, a technique described in Patent Document 1 is known. In this conventional karaoke apparatus, when performing a karaoke music reproduction service, music data by a synthesizer is reproduced and a voice signal of a karaoke song by a user is output from a microphone (wireless microphone). Then, the performance sound from the reproduction of the music data and the sound by the sound signal are synthesized by the mixing amplifier, and these sounds are emitted from the speaker to the surrounding environment. In this prior art, the prelude is repeated until the user inputs a sound to the microphone, and the main performance after the prelude is started when the sound is input.

JP 2007-57836 A

  By the way, depending on the direction of the microphone, the volume of the sound from the speaker, the situation of other surrounding environment, etc., the sound from the speaker including the sound from the microphone is input to the microphone again (so-called wraparound). There may be a howling phenomenon that produces annoying noise due to an infinite loop. When such a howling phenomenon occurs, not only does the unpleasant noise cause discomfort to the user, but it also makes it impossible to hear the music performance sound and the user's voice. As a result, even if the karaoke song data is being played back, the user is not able to receive the above services substantially, and not only the playback that is meaningless to the user continues uselessly, but also the user sings. The desired part will be left unsung and serviceability will be reduced. In the above-mentioned prior art, such a point is not particularly considered, and if there is a voice input, even if howling occurs as described above, the performance will proceed, which is inconvenient.

  An object of the present invention is to provide a karaoke apparatus capable of preventing a decrease in serviceability to a user and improving convenience even if howling occurs.

  In order to achieve the above object, the first invention is a karaoke apparatus that provides a user with a karaoke music playback service using at least music data, and a music playback means for playing back the music data; A microphone that outputs a voice signal of karaoke singing by the user, a performance sound by reproduction of the music data by the music reproduction means, and a voice by the audio signal input from the microphone can be output to a speaker Audio output means, howling determination means for determining whether or not a howling phenomenon has occurred due to input of the sound emitted from the speaker to the microphone, and determination that the howling phenomenon has occurred by the howling determination means The music playback means can be controlled not to execute the playback of the music data. And having first and reproduction control means, a.

  In the karaoke apparatus according to the first invention of the present application, a music reproducing means, a microphone, and an audio output means are provided. When the karaoke song reproduction service is executed, the song data is reproduced by the song reproducing means, and the voice signal of the karaoke song by the user is output from the microphone. Then, the performance sound by reproducing the music data and the sound by the sound signal are output from the sound output means to the speaker, and those sounds are emitted from the speaker to the surrounding environment.

  At this time, a howling phenomenon may occur depending on the direction of the microphone, the volume of sound from the speaker, the situation of other surrounding environment, and the like. Therefore, in the first invention of the present application, howling determination means and first regeneration control means are provided. When the howling determination means determines that the above-described howling phenomenon has occurred, the first reproduction control means controls the music reproduction means so that the music data is not reproduced. Thereby, when a howling phenomenon occurs, it is possible to prevent unnecessary reproduction for the user from being performed, and it is also possible that the portion the user wanted to sing does not remain unsung. As a result, it is possible to prevent deterioration in serviceability.

  The second invention is the music data corresponding to the singing period of the user when the music data is being reproduced by the music reproducing means in the first invention. Or music data determination means for determining whether the music data corresponds to a non-singing period of the user, wherein the first reproduction control means is determined by the howling determination means that the howling phenomenon has occurred, And when it is determined by the music data determination means that the music data corresponds to the singing period of the user, the music playback means is controlled so as not to reproduce the music data. .

  Karaoke music usually has a part where the user sings (part where the performance is an accompaniment of the song) and a part where the user does not sing (intro part, interlude part, ending part, etc.). include. As described above, the primary cause of the deterioration in serviceability when the howling phenomenon occurs is that even if the user wants to sing, the performance of the music cannot be heard and cannot be sung. In other words, if the user does not sing, even if the howling phenomenon occurs, the bad effect that the part that the user wanted to sing (even if it was annoying) would not be able to sing too much. There is no. Accordingly, in the second invention of the present application, music data determination means is provided, and only when the howling phenomenon occurs and when it is determined that the music data determination means corresponds to the user's singing period, The means does not execute the reproduction of the music data. In this way, by limiting the time when the howling phenomenon occurs in a scene where service degradation substantially occurs, it is possible to minimize the non-execution of reproduction of music data.

  According to a third invention, in the first or second invention, the howling determination means determines that the howling phenomenon has occurred, and the first reproduction control means does not cause the music generation means to reproduce the music data. If the howling determination means determines that the howling phenomenon has not occurred, a second playback control means for controlling the music playback means to execute playback of the music data. It is characterized by having.

  As a result, when the occurrence of the howling phenomenon is eliminated, the music data is reproduced promptly, and the original karaoke music reproduction service can be provided to the user.

  According to a fourth aspect, in the third aspect, during the reproduction of the music data by the music reproduction means, the reproduction position of the music data is measured, and the howling determination means determines that the howling phenomenon has occurred, and When the music generation means interrupts the reproduction of the music data by the control of the first reproduction control means, the reproduction position when the reproduction of the music data is interrupted is stored, and the howling phenomenon occurs by the howling determination means. If it is determined that the second reproduction control means does not, the second reproduction control means starts from the reproduction position data portion obtained by subtracting a predetermined section from the reproduction position when reproduction is interrupted by the control of the first reproduction control means. The music reproduction means is controlled to resume the reproduction of the music data.

  As a result, when a howling phenomenon occurs while the user is singing and the performance of the karaoke music and the user's singing are interrupted, the performance of the karaoke music is resumed slightly before the interrupted location. As a result, the user can surely sing again from the point where the singing is interrupted, and since the singing omission disappears, the user can continue singing with good feeling.

  According to the present invention, even when howling occurs, it is possible to prevent a decrease in serviceability to the user and improve convenience.

  Here, the feature of this embodiment is that when music data is played back, if howling occurs, the music data is not played back (not started or interrupted), which means to the user. The purpose of this is to prevent unnecessary reproduction. This will be described in detail below.

  FIG. 2 is an explanatory diagram showing a music data structure and a method for resuming data reproduction when the howling occurs in the present embodiment.

  As shown in FIG. 2A, the music data 20 includes music identification information (song ID) 21 such as a music title, time position data 22 after reproduction of music data, lyrics data 23, and MIDI as performance data. Data 24.

  The song identification information 21 is placed as a header of the song data 20, and the data portion of the song data 20 following the song identification information 21 is divided into upper and lower three stages so as to correspond on the time axis. That is, from the top to the bottom of the figure, the time position data 22 after reproduction start, the lyrics data 23, and the MIDI data 24 are arranged.

  As shown in FIG. 2 (b), the MIDI data 24 includes non-singing performance data 24a that is an intro part, an interlude part, etc. (in FIG. 2 (b), the non-singing performance data 24a is "♭ 1", "♭ 2"). .., Etc., and the singing performance data 24b as accompaniment to the user's song (in FIG. 2B, the singing performance data 24b is "# 1", "# 2", etc.) (Indicated by data with “#”).

  As described above, the MIDI data 24 is reproduced by the sound source 106 and the like, and is emitted from the speaker 108 as sound. The lyrics data 23 is displayed on the display unit 109 as lyrics telop as described above. During reproduction of the MIDI data 24, the reproduction position of the MIDI data, that is, the time position after the reproduction is started is measured by the control unit 101.

  In FIG. 2 (b), the time positions t1 to t3 after the start of reproduction are non-singing sections, and the MIDI data 23 is recorded in the non-song performance of the intro part by the sound source 106 or the like while the time positions t1 to t3 after the start of reproduction elapse. Data 24a (“♭ 1” to “♭ 3”) is reproduced. In addition, the lyrics data 23 is displayed on the display unit 109 as blanks (blanks) without lyrics (indicated by “-----” in FIGS. 2B to 2D).

  The singing section starts from the time position t4 after the start of reproduction. As the time position after the reproduction starts from t4, the singing performance data 24b corresponding to the lyrics is sequentially reproduced as the MIDI data 24, and the characters of the lyrics are sequentially displayed in the lyrics data 23. The When the singer (user) starts to sing through the microphone 105 in conjunction with the reproduction of the MIDI data 24, the voice based on the voice signal of the singer inputted from the microphone 105 reproduced the singing performance data of the MIDI data 24. Together with the performance sound, the sound is output to the speaker 108 via the sound control unit 107 and emitted (sounded) from the speaker 108.

  Then, it is assumed that a howling phenomenon occurs in the sound emitted from the speaker 105 during the singing section, that is, while the singer is singing. In this example, as shown in FIG. 2B, it is exemplified that the howling phenomenon has occurred at the end position of the time position t9 after the reproduction start. When howling occurs in the sound emitted from the speaker 105, the howling detection unit 112 detects the generated howling. Then, the playback of the singing performance data 24b by the sound source 106 and the like is interrupted (stopped), and the control unit 101 determines the position where the playback is interrupted (in this example, the end position of the time position t9 after the playback is started). Remember.

  Thereafter, when the howling phenomenon is resolved, the reproduction of the MIDI data 24 is resumed. In the present embodiment, one of the restart method (restart example 1) shown in FIG. 2C and the restart method (restart example 2) shown in FIG. 2D is executed. Which is executed may be set uniquely for each karaoke apparatus 1 or may be selectively performed by appropriate mode selection or the like in one karaoke apparatus. That is, in the resumption example 1 in FIG. 2C, when the howling phenomenon is resolved after the reproduction of the singing performance data 24b in the MIDI data 24 is interrupted, the reproduction position at the time of interruption (in this example, the time position t9 after the reproduction start). The reproduction of the singing performance data 24b is resumed from the reproduction position immediately after the reproduction end position (hereinafter referred to as the reproduction stop position) (that is, the start position of the time position t10 after reproduction start). On the other hand, in the restart example 2 of FIG. 2D, after the reproduction of the singing performance data 24b in the MIDI data 24 is interrupted, a section determined in advance from the reproduction position at the time of the interruption (the end position of the time position t9 after the reproduction start). Is resumed from the reproduction position (in this example, the start position of the time position t9 after the start of reproduction) that was traced back.

  The predetermined section may be a fixed time, or may be the first singing position of the singing section where howling has occurred. For example, if the lyrics data of the singing section displayed on the display unit 109 at the playback stop position t9 is stored together with the time information of the playback stop position t9, and restarted from the first lyrics data of the singing section, the screen Since singing is resumed from the beginning, it becomes easier to sing. Specifically, the case where the singing section is lyrics data that is simultaneously displayed on one screen of the display unit 109 will be described below as an example.

  In FIG. 2B (see also step S40 described later), the lyric data corresponding to the reproduction stop position t9 is “... Floating”, and the lyric section displayed on the screen at the display unit 109 at that time The lyric data is lyric data "Autumn ... Chidoriyo" corresponding to the time positions t4 to t12. Then, the lyrics data of the singing section stored together with the time information of the reproduction stop position t9, and the lyrics data to be sung first is “autumn...” Corresponding to the time position t4. What is necessary is just to carry out from t4.

  After that, if no howling occurs, the MIDI data 24 is reproduced to the end of the non-singing performance data 24a of the last ending portion through the non-singing section and the singing section, and then the reproduction is finished.

  Next, a control procedure executed by the control unit 101 of the karaoke apparatus 100 in order to execute the above method will be described with reference to FIG. For example, this flow is started when the karaoke apparatus 100 is turned on by a system administrator (not shown).

  In FIG. 3, first, in step S <b> 10, the control unit 101 reserves a karaoke performance song based on a karaoke performance song reservation operation performed by the singer (user) via the operation unit 104 or the operation unit 204 of the remote controller 200. Determine if it was accepted. The determination is not satisfied until the reservation of the karaoke performance song by the singer is accepted (step S10: NO), and the loop waits. And if the reservation of the karaoke performance music by a singer is received, determination will be satisfy | filled (step S10: YES), and it will move to step S20.

  In step S <b> 20, the control unit 101 determines whether howling has occurred in the sound emitted from the speaker 108 based on the detection result of the howling detection unit 112. As described above, when howling occurs in the sound emitted from the speaker 108, the howling detection unit 112 detects howling. If the occurrence of howling is detected, the determination is satisfied (step S20: YES), and the control unit 101 proceeds to step S30. If the occurrence of howling is not detected, the determination is not satisfied (step S20: NO), and the control unit 101 proceeds to step S70 described later.

  In step S30, the control unit 101 determines whether or not the reproduction of the music data 20 by the sound source 106 or the like is a singing section. If the singing performance data 24b in the MIDI data 24 is reproduced by the sound source 106 or the like, the determination is satisfied (step S30: YES), and the process proceeds to step S40. If the non-singing performance data 24a in the MIDI 24 is reproduced by the sound source 106 or the like, the determination is not satisfied (step S30: NO), and the process proceeds to step S70 described later.

  In step S40, the control unit 101 determines that the reproduction of the MIDI data 24 by the sound source 106 or the like is not executed (that is, the reproduction is interrupted if the reproduction is performed, and the reproduction is not started unless the reproduction is performed). A reproduction stop position due to non-execution of reproduction (t9 in the example of FIG. 2B) is stored. Thereafter, the process proceeds to step S50.

  At this time, the time position data 22, the lyrics data 23, and the MIDI data 24 are associated with each other. Therefore, the time position data 22 may be stored as the stop position, but the lyrics data 23 of the lyrics corresponding to the stop position or the MIDI data 24 corresponding to the stop position is stored, and the resumption of the performance is performed. The data may be read out, and the restart position of each other may be specified from any one of the time position data, the lyrics data, and the MIDI data.

  In step S50, the control unit 101 determines whether howling has been resolved based on the detection result of the howling detection unit 112. If howling is not resolved, the determination is not satisfied (step S50: NO), and a loop standby is performed. If howling is eliminated, the determination is satisfied (step S50: YES), and the routine goes to step S60.

  In step S60, the control unit 101 reproduces the song performance data 24b based on the reproduction position (stop position) of the song performance data 24b of the MIDI data 24 when the reproduction stored in step S40 is interrupted (stopped). To do. At that time, when the above restart example 1 is executed, as described above, the singing performance data 24b is reproduced from the reproduction position immediately after the reproduction position (stop position) of the singing performance data 24b at the time of the reproduction interruption. Run. On the other hand, when the above restart example 2 is executed, as described above, a predetermined section slightly before the playback position (stop position) of the singing performance data 24b at the time of the playback interruption is subtracted to the previous stage. The singing performance data 24b is reproduced from the reproduced position. Thereafter, the process proceeds to step S80.

  On the other hand, in step S70, which has shifted from steps S20 and S30, the control unit 101 reproduces the MIDI data 24 by the sound source 106 or the like. That is, when no howling has occurred (when the determination in step S20 is not satisfied), since there is no howling, the MIDI data 24 is reproduced as it is. Moreover, even if howling has occurred, it is not occurring in the singing section (when the determination in step S30 is not satisfied), that is, in the case of occurrence in the non-singing section, the adverse effect on the user's singing is a problem. Since there is no need, the non-singing performance data 24a of the MIDI data 24 is reproduced. When step S70 ends, the process proceeds to step S80.

  In step S80, the control unit 101 determines whether or not the playback of the MIDI data 24 has been completed and the performance of the music has ended. If the performance of the music has not ended, the determination is not satisfied (step S80: NO), and the process returns to step S20 and the same procedure is repeated. When the performance of the music is finished, the determination is satisfied (step S80: YES), and this flow is finished.

  In the above, the procedures of step S20 and step S50 function as howling determination means described in each claim, the procedure of step S30 functions as music data determination means described in each claim, and the procedure of step S40 corresponds to each claim. Function as the first reproduction control means described, and the procedure of step S50 functions as the second reproduction control means described in each claim.

  As described above, in the karaoke apparatus 100 of the present embodiment, when a howling phenomenon occurs, it is possible to prevent the music data from being reproduced in step S40. Thereby, when a howling phenomenon occurs, it is possible to prevent unnecessary reproduction for the user from being performed, and it is also possible that the portion the user wanted to sing does not remain unsung. As a result, it is possible to prevent deterioration in serviceability.

  However, the karaoke music usually corresponds to a portion where the user sings (a portion where the performance is accompanied by a song) and non-singing performance data 24a as in the singing performance data 24b. A portion where the user does not sing (intro portion, interlude portion, ending portion, etc.) is included. As described above, the primary cause of the deterioration in serviceability when the howling phenomenon occurs is that even if the user wants to sing, the performance of the music cannot be heard and cannot be sung. In other words, if the user does not sing, even if the howling phenomenon occurs, the bad effect that the part that the user wanted to sing (even if it was annoying) would not be able to sing too much. There is no.

  Therefore, in the present embodiment, in particular, based on the determination result in step S30, only when the howling phenomenon occurs and when the howling phenomenon occurs corresponds to the singing period of the user, Playback is not executed. In this way, by limiting the time when the howling phenomenon occurs in a scene where service degradation substantially occurs, it is possible to minimize the non-execution of reproduction of music data.

  In the present embodiment, in particular, when the howling phenomenon occurs in step S60 after step S50, the music data is controlled not to be reproduced, and then the music data is reproduced when the howling phenomenon is resolved. Execute. As a result, when the occurrence of the howling phenomenon is eliminated, the music data is reproduced promptly, and the original karaoke music reproduction service can be provided to the user.

  In the present embodiment, in particular, in the above restart example 2, when the howling phenomenon is resolved, the music data is obtained from the data portion of the reproduction position obtained by subtracting a predetermined section from the reproduction position when reproduction is interrupted. Resume playback of. Thereby, when a howling phenomenon occurs during the user's singing and the user's singing is interrupted, the performance is resumed slightly before the interrupted portion when the performance of the karaoke music is resumed. As a result, the user can surely sing again from the point where the singing is interrupted, and since the singing omission disappears, the user can continue singing with good feeling.

  Note that the flowchart shown in FIG. 3 does not limit the present invention to the procedure shown in the above-described flow, and the procedure may be added or deleted or the order may be changed without departing from the spirit and technical idea of the invention. Good.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
