[First embodiment]
A karaoke system 100 according to a first embodiment of the present invention will now be described.

[Karaoke system]
Fig. 1 is a block diagram showing the configuration of a karaoke system 100 according to a first embodiment. As shown in Fig. 1, the karaoke system 100 has multiple karaoke machines 1 (1a, 1b, 1c), which are connected to each other so that they can communicate with each other. In this embodiment, an example will be described in which the karaoke system 100 has three karaoke machines 1a, 1b, 1c, but in the present invention, it is sufficient if the karaoke system has two or more karaoke machines 1.

Karaoke machines 1a, 1b, and 1c are installed in the respective rooms of a karaoke booth or similar facility that has multiple rooms. For example, karaoke machine 1b is installed in the room adjacent to the right of the room where karaoke machine 1a is installed, and karaoke machine 1c is installed in the room adjacent to the left of the room where karaoke machine 1a is installed.

Since the multiple karaoke machines 1a, 1b, and 1c each have a similar configuration, they will be described in detail as karaoke machine 1 in this embodiment. Below, it is assumed that karaoke machine 1 (for example, karaoke machine 1a) is installed in one of the multiple rooms, and the other karaoke machines 1 (for example, other karaoke machines 1b and 1c) are installed in other of the multiple rooms adjacent to the first room. Furthermore, Figure 1 shows the detailed configuration of karaoke machine 1a, and omits detailed illustrations of karaoke machines 1b and 1c.

[Karaoke equipment]
The karaoke machine 1 has a function of recommending (recommending) recommended songs to the user in addition to a function of performing karaoke of the selected songs. As shown in Fig. 1, the karaoke machine 1 includes a karaoke main unit 2, a sound collection unit 3, a speaker 4, a display device 5 such as a monitor, and a remote control device 6. The karaoke main unit 2 is connected to the sound collection unit 3, the speaker 4, the display device 5, and the remote control device 6 by wire or wirelessly.

The sound collection unit 3 converts sounds around the karaoke device 1 into audio signals and inputs them to the karaoke main unit 2. The sound collection unit 3 has a microphone that inputs the user's singing voice and transmits it to the karaoke main unit 2. For example, the sound collection unit 3 has multiple microphones (handheld microphones) or a stereo microphone (handheld microphone) that has directionality that allows the direction from which the sound is emitted to be identified.

For example, the sound collection unit 3 collects sound emitted to the left side from the perspective of the karaoke device 1 and inputs a left-side sound signal, and collects sound emitted to the right side and inputs a right-side sound signal. The sound collection unit 3 may also collect sound emitted in front from the perspective of the karaoke device 1 and input a front sound signal, or collect sound emitted behind and input a rear sound signal. The sound collection unit 3 may also be provided with multiple microphones or a stereo microphone in the karaoke main unit 2 itself, making it possible to identify the direction from which the sound is emitted.

The speaker 4 emits the user's singing voice along with the karaoke performance of the song based on the sound emission signal from the karaoke unit 2. The display device 5 displays various screens based on the video signal etc. from the karaoke unit 2, for example, displaying lyrics captions along with background images in time with the karaoke performance.

The remote control device 6 is primarily composed of a touch panel. The remote control device 6 displays various screens and operation buttons on the touch panel, and also accepts login operations and song selection (reservation) operations via the touch panel. The remote control device 6 and karaoke machine main unit 2 are paired via wireless communication, allowing various information to be sent and received between the remote control device 6 and the karaoke machine main unit 2.

The remote control device 6 transmits user identification information (user ID) and other information entered in response to the user's login operation to the karaoke unit 2. The remote control device 6 accepts song searches and song selections (reservations), and transmits song identification information (song ID) of songs selected in response to the user's song selection operation to the karaoke unit 2 as reserved song information.

The karaoke machine main unit 2 comprises a control unit 10, a memory unit 11, a sound source 12, and an audio input/output unit 13. The control unit 10 is configured with a CPU (Central Processing Unit) and other components, and provides overall control of the karaoke machine main unit 2. The memory unit 11 is configured with storage media such as ROM (Read Only Memory), RAM (Random Access Memory), and HDD (Hard Disc Drive), and stores programs and data for controlling each unit and function of the karaoke machine 1.

For example, the memory unit 11 stores the user ID of each user of the karaoke machine 1 to identify each user. The control unit 10 receives the user ID entered in response to the user's login operation from the remote control device 6 and confirms that the received user ID is stored in the memory unit 11, thereby accepting the user's login. This allows the user to log in to the karaoke machine 1 or to the karaoke system 100 to which the karaoke machine 1 belongs.

The storage unit 11 stores basic information such as the song ID, song title, singer name, and genre for each song that the karaoke device 1 can perform. The storage unit 11 also stores song data for each song, which includes performance data, reference data, and lyric data. Among the song data, the performance data is MIDI-format data that serves as the basis for the accompaniment sounds of a karaoke performance. The reference data is pitch information used as a standard for evaluating a user's karaoke singing. The lyric data is data that serves as the basis for the lyric captions displayed on the display device 5.

The storage unit 11 stores a reservation list for sequentially registering reservation song information for songs reserved on the karaoke device 1. The storage unit 11 also stores, for each user of the karaoke device 1, the song IDs of songs performed in karaoke, associated with the currently logged-in user ID, as the singing history of that user.

Furthermore, the memory unit 11 stores the location information of each of the other karaoke devices 1 installed in each of the rooms adjacent to the room in which the karaoke device 1 is installed. For example, the memory unit 11 of one karaoke device 1a installed in one room stores a location information table containing the location information of the other karaoke devices 1b and 1c installed in the other rooms adjacent to the one room. As shown in FIG. 2, the location information of each of the other karaoke devices 1b and 1c stores the installation direction indicating the direction of the other karaoke devices 1b and 1c from the perspective of the one karaoke device 1a, and the device identification information (device ID) of each of the other karaoke devices 1b and 1c, in association with each other.

The sound source 12 is, for example, a MIDI sound source, and is a karaoke performance means that generates a karaoke performance signal based on the performance data of the song data. When the control unit 10 reads song data corresponding to the songs from the storage unit 11 in the order in which the songs are registered in the reservation list in the storage unit 11, the sound source 12 generates a performance signal based on the performance data of the read song data and outputs it to the audio input/output unit 13.

The audio input/output unit 13 is composed of a mixer (digital mixer), amplifier, etc., and mixes the karaoke performance signal and the karaoke singing audio signal, amplifying this mixed signal to be emitted from the speaker 4. The volume level of the karaoke performance signal and singing audio signal reflects the music volume setting made by the user. For example, the audio input/output unit 13 is connected to the sound source 12 and inputs the performance signal from the sound source 12, and is also connected to the sound collection unit 3 and inputs the audio signal from the sound collection unit 3. The audio input/output unit 13 is connected to the speaker 4 and outputs the mixed signal of the performance signal and audio signal to the speaker 4 to emit sound.

The control unit 10 controls each unit and function of the karaoke device 1 by executing calculations based on the programs and data stored in the memory unit 11. For example, in this embodiment, the control unit 10 operates as a detection unit 20, identification unit 21, request unit 22, and recommendation unit 23 by executing the programs stored in the memory unit 11, and has a recommendation function that presents and recommends recommended songs to the user while the performance of a song is stopped.

The detection unit 20 detects karaoke audio emitted from another karaoke device 1 installed in an adjacent room by collecting sound using the sound collection unit 3 while the music is stopped. Since the karaoke device 1 is installed in a room such as a karaoke room equipped with soundproofing, the audio heard through the wall from the adjacent room may be determined to be karaoke performance audio or karaoke singing audio amplified and emitted by the other karaoke device 1 installed in the adjacent room. Therefore, the detection unit 20 detects the audio input to the sound collection unit 3 as karaoke audio, such as karaoke performance audio or karaoke singing audio, emitted by the other karaoke device 1. The detection unit 20 may also apply technology described in Patent Application No. 2020-143600 to distinguish and detect karaoke audio emitted by the other karaoke device 1 from the audio input to the sound collection unit 3.

When karaoke voice is detected by the detection unit 20, the identification unit 21 identifies the recommended karaoke device 1 that corresponds to the karaoke voice from among the other karaoke devices 1. For example, the identification unit 21 identifies the recommended karaoke device 1 that corresponds to the karaoke voice detected by the detection unit 20 based on the positional relationship between the sound collection unit 3 and the other karaoke devices 1. At this time, the identification unit 21 uses the directionality of the sound collection unit 3 to determine from which direction the karaoke voice is emitted as viewed from the karaoke device 1, i.e., determines the direction of the sound emission source.

For example, when the left audio signal and the right audio signal input to the sound collection unit 3 include karaoke audio and the right audio signal does not include karaoke performance, the identification unit 21 determines the left side as the sound emission direction. On the other hand, when the right audio signal includes karaoke audio and the left audio signal does not include karaoke performance, the identification unit 21 determines the right side as the sound emission direction. Alternatively, when both the left audio signal and the right audio signal input to the sound collection unit 3 include karaoke audio, the identification unit 21 determines the left side as the sound emission direction if the level of the left audio signal is greater than that of the right audio signal. On the other hand, the identification unit 21 determines the right side as the sound emission direction if the level of the right audio signal is greater than that of the left audio signal.

The identification unit 21 also acquires from the storage unit 11 the location information of each of the other karaoke devices 1 installed in each of the other rooms adjacent to the room in which the karaoke device 1 is installed. The identification unit 21 then identifies a recommended karaoke device 1 that corresponds to the karaoke sound based on the installation direction of the other karaoke devices 1 and the sound emission direction of the karaoke sound contained in the acquired location information. For example, the identification unit 21 identifies a recommended karaoke device 1 from among the other karaoke devices 1 whose installation direction and sound emission direction match.

The request unit 22 requests song identification information (song ID) of the song currently being played from the karaoke device 1 to be recommended that has been identified by the identification unit 21, and for example, transmits a song request requesting the song ID. The request unit 22 may recognize the karaoke device 1 to be recommended by receiving the device ID of the karaoke device 1 to be recommended from the identification unit 21. At this time, the karaoke device 1 to be recommended acquires the song ID of the song currently being played in response to the song request, and transmits the song ID as a response to the karaoke device 1 that transmitted the song request.

The recommendation unit 23 acquires song identification information (song ID) from the karaoke device 1 to be recommended that has responded to the song request from the request unit 22, and recommends (recommends) a song (recommended song) to the user based on the song ID. At this time, the recommendation unit 23 displays a recommendation screen on the display device 5 or remote control device 6 that displays the song title and artist name of the recommended song and accepts song selection (reservation) operations for the recommended song, and recommends it to the user. The recommendation unit 23 displays this recommendation screen while the song is stopped when the detection unit 20 detects karaoke voice. Note that the recommendation unit 23 may also display this recommendation screen while the song is stopped after the next song has been played. Furthermore, the recommendation unit 23 does not need to recommend a recommended song if the recommended song is already being played on the karaoke device 1.

[Recommended operation of the first embodiment]
Next, an example of a recommendation operation of the karaoke device 1 of the first embodiment for recommending a song based on the karaoke voice of another karaoke device 1 will be described with reference to Fig. 3. Fig. 3 is a flowchart showing an example of the recommendation operation of the karaoke device 1 of the first embodiment.

In this example, when viewed from one karaoke device 1a installed in one room, another karaoke device 1b (device ID: ****1) is installed in another adjacent room to the right, and another karaoke device 1c (device ID: ****2) is installed in another adjacent room to the left. Furthermore, while performance of the first karaoke device 1a is stopped, the other karaoke device 1b on the right is playing karaoke of song B (song ID: ****B), and the other karaoke device 1c on the left is not playing karaoke.

If the karaoke device 1a is currently playing a song (step S101: No), it ends the recommended operation. On the other hand, if the song is not playing (step S101: Yes), the detection unit 20 of the karaoke device 1a detects whether karaoke audio is being emitted from the other karaoke devices 1b and 1c in adjacent rooms (step S102).

If no karaoke voice is being emitted from the other karaoke devices 1b, 1c (Step S102: No), the first karaoke device 1a ends the recommendation operation. On the other hand, if the detection unit 20 detects karaoke voice being emitted from the other karaoke device 1b (Step S102: Yes), the identification unit 21 of the first karaoke device 1a determines from which direction the detected karaoke voice is being emitted, and identifies the recommended karaoke device 1b corresponding to the detected karaoke voice based on the positional relationship between the sound collection unit 3 and the other karaoke device 1b (Step S103).

The request unit 22 of the first karaoke device 1a then sends a song request to the identified recommended karaoke device 1b, requesting the song ID of the song currently being played (step S104). In response to the song request, the recommended karaoke device 1b sends the song ID (****B) of song B currently being played to the first karaoke device 1a. The first karaoke device 1a then receives and acquires the song ID (****B) of song B from the recommended karaoke device 1b (step S105).

The recommendation unit 23 of one karaoke device 1a acquires the song ID (****B) of song B received from the recommended karaoke device 1b that responded to the song request, and recommends song B (recommended song) based on that song ID to the user (step S106).

As described above, according to the first embodiment of the present invention, the karaoke system 100 includes multiple karaoke devices 1 installed in adjacent rooms and connected to each other for communication. Each karaoke device 1 installed in a room includes a sound collection unit 3 that collects sound and a control unit 10. The control unit 10 operates as a detection unit 20, identification unit 21, request unit 22, and recommendation unit 23. The detection unit 20 detects karaoke audio emitted from another karaoke device 1 installed in an adjacent room from the audio collected by the sound collection unit 3 while the performance of the song is stopped. The identification unit 21 identifies a karaoke device 1 to be recommended that corresponds to the karaoke audio detected by the detection unit 20. The request unit 22 sends a song request for song identification information of the song currently being played to the karaoke device 1 to be recommended identified by the identification unit 21. The recommendation unit 23 obtains song identification information from the karaoke device 1 to be recommended that responded to the song request from the request unit 22, and recommends a song to the user based on the song identification information.

As a result, in the karaoke system 100, when a song being played on another karaoke device 1 in another room is heard while the performance of that song is stopped in a room where a karaoke device 1 is installed, the karaoke device 1 can recommend that song. This allows users to enjoy singing karaoke to a variety of songs, thereby promoting the use of the karaoke device 1.

Furthermore, according to the first embodiment of the present invention, in the karaoke system 100, the identification unit 21 of one karaoke device 1 identifies the recommended karaoke device 1 that corresponds to the karaoke voice detected by the detection unit 20, based on the positional relationship between the sound collection unit 3 and the other karaoke devices 1.

This allows the location information of other karaoke devices 1 to be used to properly identify the recommended karaoke device 1 that is emitting the karaoke audio heard in the first room.

Second Embodiment
A karaoke system 100 according to a second embodiment of the present invention will now be described. As shown in Fig. 4, the second embodiment has the same configuration as the first embodiment. In the description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

In the karaoke device 1 of the karaoke system 100 of the second embodiment, as in the first embodiment, the control unit 10 operates as the detection unit 20, identification unit 21, request unit 22, and recommendation unit 23 by executing a program stored in the memory unit 11. However, in the second embodiment, the identification unit 21 identifies the karaoke device 1 to be recommended that corresponds to the karaoke voice detected by the detection unit 20 based on the volume information of the other karaoke devices 1, rather than the location information of the other karaoke devices 1. Note that in the second embodiment, the memory unit 11 does not need to store the location information of the other karaoke devices 1; it is sufficient to store the device identification information (device ID) of each of the other karaoke devices 1 installed in each of the other rooms adjacent to the room in which the karaoke device 1 is installed.

The identification unit 21 recognizes each of the other adjacent karaoke devices 1 based on the stored device ID, and requests volume information for the karaoke performance from each of the other karaoke devices 1, for example, by transmitting a volume request requesting the volume information. At this time, the other karaoke devices 1 obtain the volume information set for the karaoke performance and transmit the volume information as a response to the karaoke device 1 that transmitted the volume request. The volume information may be a set volume set using a music volume that divides the volume into multiple levels, or may be a set volume expressed in decibels (dB).

The identification unit 21 acquires volume information from each of the other karaoke devices 1 that responded to the volume request, and, based on the volume information, identifies from among the other karaoke devices 1 a karaoke device 1 to be recommended that corresponds to the karaoke voice detected by the detection unit 20. For example, the identification unit 21 identifies, among the other karaoke devices 1, the one with the louder volume information as the karaoke device 1 to be recommended.

[Recommended operation of the second embodiment]
Next, an example of a recommendation operation of the karaoke device 1 of the second embodiment, which recommends songs based on the karaoke voice of another karaoke device 1, will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of the recommendation operation of the karaoke device 1 of the second embodiment.

In this example, volume information is set in each karaoke device 1 within the range of a minimum value of 0 to a maximum value of 100. While one karaoke device 1a is stopped, the other karaoke device 1b on the right has volume information set to 50 and is playing karaoke of song B (song ID: ****B), while the other karaoke device 1c on the left has volume information set to 0 and is not playing karaoke. Note that when the other karaoke devices 1 are not playing karaoke, they respond to a volume information request (volume request) by sending volume information of 0.

Similar to steps S101 and S102 in the first embodiment, when the performance of a song is stopped (step S201: No), the detection unit 20 of one karaoke device 1a detects whether karaoke audio is being emitted from another adjacent karaoke device 1b or another adjacent karaoke device 1c (step S202).

If the detection unit 20 detects karaoke voices from the other karaoke device 1b (step S202: Yes), the identification unit 21 of the first karaoke device 1a sends a volume request to the other karaoke devices 1b and 1c (step S203). The identification unit 21 also receives and acquires volume information from the other karaoke devices 1b and 1c that responded to the volume request (step S204). The identification unit 21 then identifies the recommended karaoke device 1b that corresponds to the detected karaoke voice based on the volume information of the other karaoke devices 1b and 1c (step S205).

Then, similar to steps S104 and S105 in the first embodiment, the request unit 22 of the first karaoke device 1a sends a song request to the karaoke device 1b to be recommended (step S206), and receives and acquires the song ID (****B) of song B being played from the karaoke device 1b to be recommended (step S207).

Furthermore, similar to step S106 in the first embodiment, the recommendation unit 23 of the first karaoke device 1a recommends to the user song B (recommended song) that is being played on the target karaoke device 1b based on the acquired song ID (step S208).

As described above, according to the second embodiment of the present invention, in the karaoke system 100, the identification unit 21 of one karaoke device 1 makes a volume request for karaoke performance volume information to another karaoke device 1, acquires volume information from the other karaoke device 1 that responds to the volume request, and identifies the recommended karaoke device 1 that corresponds to the karaoke voice detected by the detection unit 20 based on the volume information.

As a result, by using the volume information of the other karaoke devices 1, it is possible to appropriately identify the recommended karaoke device 1 that is emitting the karaoke voice heard in the first room.
[Modification]

In the above second embodiment, the control unit 10 of the karaoke machine 1 operates as an identification unit 21, making a volume request to another karaoke machine 1 and identifying the karaoke machine 1 to be recommended based on volume information acquired from the other karaoke machine 1, and also operates as a request unit 22, making a song request to the karaoke machine 1 to be recommended and acquiring song identification information (song ID) of the song being played from the karaoke machine 1 to be recommended. However, the present invention is not limited to this example.

As a variation of the second embodiment, the identification unit 21 of the control unit 10 of the karaoke device 1 may be configured to also perform the functions of the request unit 22. The identification unit 21 of this variation simultaneously requests the volume information of the karaoke performance and the song ID of the song being played from each of the other karaoke devices 1, and identifies the karaoke device 1 to be recommended and determines the recommended song based on the volume information and song ID obtained from each of the other karaoke devices 1.

For example, the identification unit 21 recognizes each of the other adjacent karaoke devices 1 based on the stored device ID, and sends a song request requesting both volume information and a song ID to each of the other karaoke devices 1. At this time, the other karaoke devices 1 obtain the volume information of the karaoke performance and the song ID of the song being played, and send the volume information and song ID as a response to the karaoke device 1 that sent the song request.

The identification unit 21 also acquires volume information and song IDs from each of the other karaoke devices 1 that have responded to the song request. Then, as in the second embodiment, the identification unit 21 identifies a recommended karaoke device 1 from among the other karaoke devices 1 that corresponds to the karaoke voice based on the acquired volume information. Furthermore, the karaoke device 1 selects, from among the song IDs acquired from the other karaoke devices 1, a song ID corresponding to the recommended karaoke device 1 as a recommended song to be recommended by the recommendation unit 23.

[Recommended operation of modified example]
Next, an example of a recommendation operation of the karaoke device 1 according to the modification of the second embodiment, which recommends songs based on the karaoke voice of another karaoke device 1, will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the recommendation operation of the karaoke device 1 according to the modification of the second embodiment.

Similar to steps S201 and S202 in the second embodiment, when the performance of a song is stopped (step S301: No), the detection unit 20 of one karaoke device 1a detects whether karaoke audio is being emitted from another adjacent karaoke device 1b or another adjacent karaoke device 1c (step S302).

If the detection unit 20 detects karaoke voices from the other karaoke device 1b (step S302: Yes), the identification unit 21 of the first karaoke device 1a sends a song request to the other karaoke devices 1b and 1c, requesting both the volume information of the karaoke performance and the song ID of the song being played (step S303). The identification unit 21 also receives and acquires the volume information and song ID from the other karaoke devices 1b and 1c that responded to the song request (step S304). The identification unit 21 then identifies the recommended karaoke device 1b that corresponds to the detected karaoke voice based on the volume information of the other karaoke devices 1b and 1c (step S305).

The recommendation unit 23 of the first karaoke device 1a recommends to the user, from among the song IDs acquired from the other karaoke devices 1b and 1c, song B with song ID (****B) corresponding to the recommended karaoke device 1b (step S306).

As a result, according to the modified example of the second embodiment, the number of request procedures sent from the karaoke device 1 to each of the other karaoke devices 1 can be reduced.

In the above-described embodiments, an example has been described in which the karaoke system 100 is configured to include multiple karaoke devices 1 connected to each other in a communicative manner. However, the present invention is not limited to this example, and other examples of the karaoke system 100 may be configured to include an external server in addition to multiple karaoke devices 1.

Furthermore, the present invention may be modified as appropriate within the scope of the claims and the spirit or concept of the invention as can be read from the entire specification, and karaoke systems incorporating such modifications are also included within the technical concept of the present invention.
