DETAILED DESCRIPTION OF THE INVENTION

[0010] [First embodiment] A karaoke system 100 according to a first embodiment of the present invention will be described below.

[0011] [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.

[0012] Karaoke machines 1a, 1b, and 1c are installed in the respective rooms of a karaoke booth or the like having multiple rooms. For example, karaoke machine 1b is installed in the room adjacent to the right of karaoke machine 1a, and karaoke machine 1c is installed in the room adjacent to the left of karaoke machine 1a.

[0013] Since the multiple karaoke machines 1a, 1b, and 1c each have the same configuration, they will be described in detail as karaoke machine 1 in this embodiment. In the following, 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 rooms adjacent to the first of the multiple rooms. Also, in FIG. 1, the detailed configuration of karaoke machine 1a is shown, and the detailed illustration of karaoke machines 1b and 1c is omitted.

[0014] [Karaoke equipment] The karaoke device 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 device 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.

[0015] 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, and may have, for example, multiple microphones (handheld microphones) or a stereo microphone (handheld microphone) with directionality that allows the direction of the sound emission source to be identified.

[0016] For example, the sound collection unit 3 collects sounds emitted to the left side as viewed from the karaoke device 1 to input a left-side sound signal, and also collects sounds emitted to the right side as input a right-side sound signal. The sound collection unit 3 may also collect sounds emitted in front as viewed from the karaoke device 1 to input a front sound signal, or collect sounds emitted behind as 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 to enable identification of the direction from which the sounds are emitted.

[0017] 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 main unit 2. The display device 5 displays various screens based on the video signal etc. from the karaoke main unit 2, for example, displaying lyrics captions along with background images in time with the karaoke performance.

[0018] The remote control device 6 is mainly composed of a touch panel. The remote control device 6 displays various screens and various 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 the karaoke main unit 2 are paired via wireless communication, allowing various information to be transmitted and received between them.

[0019] The remote control device 6 transmits user identification information (user ID) and the like input in response to the user's login operation to the karaoke main unit 2. The remote control device 6 accepts song searches and song selections (reservations), and transmits song identification information (song ID) of the song selected in response to the user's song selection operation to the karaoke main unit 2 as reserved song information.

[0020] The karaoke main unit 2 includes a control unit 10, a memory unit 11, a sound source 12, and an audio input / output unit 13. The control unit 10 includes a CPU (Central Processing Unit) and other components, and controls the karaoke main unit 2. The memory unit 11 includes storage media such as a 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 device 1.

[0021] For example, the storage 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 storage 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.

[0022] The storage unit 11 stores basic information such as song ID, song title, singer name, genre, etc. 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. 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 that is 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.

[0023] The storage unit 11 stores a reservation list for sequentially registering reservation song information of 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 by the user as the singing history of the user, in association with the logged-in user ID.

[0024] Furthermore, the storage unit 11 stores the location information of each of the other karaoke devices 1 installed in the rooms adjacent to the room where the karaoke device 1 is installed. For example, the storage 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, 1c installed in the rooms adjacent to the one room. As the location information of each of the other karaoke devices 1b, 1c, as shown in Fig. 2, the installation direction indicating the direction of the other karaoke devices 1b, 1c as seen from the first karaoke device 1a, and the device identification information (device ID) of each of the other karaoke devices 1b, 1c are stored in association with each other.

[0025] The sound source 12 is a karaoke performance means, which is composed of, for example, a MIDI sound source, and generates a performance signal for a karaoke performance based on the performance data of the song data. When the control unit 10 reads out the song data corresponding to the songs from the storage unit 11 in the order in which the songs are registered in the reservation list of 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.

[0026] The audio input / output unit 13 is comprised of a mixer (digital mixer), an amplifier, etc., and mixes the karaoke performance signal and the karaoke singing audio signal, and amplifies this mixed signal to emit sound from the speaker 4. The volume levels of the karaoke performance signal and the singing audio signal reflect 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 the audio signal to the speaker 4 to emit sound.

[0027] The control unit 10 controls each unit and function of the karaoke device 1 by executing calculations based on programs and data stored in the storage unit 11. For example, the control unit 10 of this embodiment operates as a detection unit 20, an identification unit 21, a request unit 22, and a recommendation unit 23 by executing a program stored in the storage unit 11, and has a recommendation function of presenting and recommending recommended songs to the user while the performance of a song is stopped.

[0028] The detection unit 20 detects karaoke sounds 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 soundproof karaoke room, the sound heard through the wall from the adjacent room may be determined to be a karaoke performance sound or karaoke singing sound amplified and emitted by the other karaoke device 1 installed in the adjacent room. Therefore, the detection unit 20 detects the sound input to the sound collection unit 3 as karaoke sounds such as karaoke performance sounds or karaoke singing sounds emitted by the other karaoke device 1. The detection unit 20 may also apply technology described in Japanese Patent Application No. 2020-143600 to distinguish and detect karaoke sounds emitted by the other karaoke device 1 from the sound input to the sound collection unit 3.

[0029] When karaoke voice is detected by the detection unit 20, the identification unit 21 identifies a recommended karaoke device 1 corresponding to the karaoke voice from among the other karaoke devices 1. For example, the identification unit 21 identifies a recommended karaoke device 1 corresponding 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 directivity of the sound collection unit 3 to determine from which direction the karaoke voice is emitted as viewed from the karaoke device 1, that is, determines the sound emission direction.

[0030] For example, when the left audio signal and the right audio signal input to the sound collection unit 3 include karaoke audio and do 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 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.

[0031] The identifying unit 21 also acquires from the storage unit 11 the location information of each of the other karaoke devices 1 installed in the other rooms adjacent to the room where the karaoke device 1 is installed. The identifying unit 21 then identifies a recommended karaoke device 1 that corresponds to the karaoke voice based on the installation direction of the other karaoke devices 1 and the sound emission direction of the karaoke voice included in the acquired location information. For example, the identifying unit 21 identifies, from among the other karaoke devices 1, a recommended karaoke device 1 whose installation direction and sound emission direction match.

[0032] The requesting unit 22 requests song identification information (song ID) of the song currently being played by the karaoke device 1 to be recommended that has been identified by the identifying unit 21, and transmits, for example, a song request requesting the song ID. The requesting 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 identifying 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.

[0033] 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) based on the song ID to the user. At this time, the recommendation unit 23 displays a recommendation screen on the display device 5 or the remote control device 6, which displays the song title and artist name of the recommended song and accepts song selection (reservation) operations for the recommended song, to recommend the song to the user. The recommendation unit 23 displays such a recommendation screen during a period when the performance of the song is stopped when the detection unit 20 detects karaoke voice. Note that the recommendation unit 23 may also display such a recommendation screen during a period when the performance of the next song is stopped after the performance of the next song. Furthermore, the recommendation unit 23 does not need to recommend a recommended song if the karaoke performance of the recommended song has already been performed on the karaoke device 1.

[0034] [Recommended operation of the first embodiment] Next, an example of a recommendation operation of the karaoke device 1 of the first embodiment to recommend 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.

[0035] In this example, from the perspective of 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. Also, while 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.

[0036] If the karaoke device 1a is currently playing a song (step S101: No), the recommended operation is terminated. 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 sounds are being emitted from the other karaoke devices 1b and 1c in the adjacent rooms (step S102).

[0037] 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 sound-emitting 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).

[0038] The request unit 22 of the first karaoke device 1a then transmits a song request to the identified karaoke device 1b to be recommended, requesting the song ID of the song currently being played (step S104). In response to the song request, the karaoke device 1b to be recommended transmits 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 karaoke device 1b to be recommended (step S105).

[0039] The recommendation unit 23 of one karaoke device 1a acquires the song ID (*****B) of song B received from the karaoke device 1b to be recommended in response to the song request, and recommends song B (recommended song) based on the song ID to the user (step S106).

[0040] As described above, according to the first embodiment of the present invention, the karaoke system 100 includes a plurality of 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 functions as a detection unit 20, an identification unit 21, a request unit 22, and a recommendation unit 23. The detection unit 20 detects karaoke sounds emitted from another karaoke device 1 installed in an adjacent room from the sound collected by the sound collection unit 3 while the performance of a song is stopped. The identification unit 21 identifies a karaoke device 1 to be recommended that corresponds to the karaoke sounds 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 that has been identified by the identification unit 21. The recommendation unit 23 obtains song identification information from the karaoke device 1 to be recommended that has responded to the song request from the request unit 22, and recommends a song to the user based on the song identification information.

[0041] As a result, in the karaoke system 100, when a song being played by another karaoke device 1 in another room is heard while the performance of the song is stopped in one room where one karaoke device 1 is installed, the song can be recommended by the one karaoke device 1. This allows users to enjoy singing karaoke of a variety of songs, thereby promoting the use of the karaoke device 1.

[0042] 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 corresponding 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.

[0043] As a result, by using the location information of the other karaoke devices 1, it is possible to appropriately identify the recommended karaoke device 1 that is emitting the karaoke sound heard in the first room.

[0044] [Second embodiment] A karaoke system 100 according to a second embodiment of the present invention will be described below. As shown in Fig. 4, the second embodiment has the same configuration as the first embodiment, and 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.

[0045] In the karaoke device 1 of the karaoke system 100 of the second embodiment, as in the first embodiment, the control unit 10 executes the programs stored in the storage unit 11 to operate as the detection unit 20, the identification unit 21, the request unit 22, and the recommendation unit 23. 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 on the location information of the other karaoke devices 1. Note that in the second embodiment, the storage unit 11 does not need to store the location information of the other karaoke devices 1, but only needs 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 where the karaoke device 1 is installed.

[0046] The identifying 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 by a music volume or the like that divides the volume into multiple levels, or may be a set volume expressed in decibels (dB).

[0047] The identifying unit 21 acquires volume information from each of the other karaoke devices 1 that have 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 detecting unit 20. For example, the identifying unit 21 identifies, among the other karaoke devices 1, the one with the louder volume information as the karaoke device 1 to be recommended.

[0048] [Recommended operation of the second embodiment] Next, an example of a recommendation operation of the karaoke device 1 of the second embodiment to recommend a song 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.

[0049] In this example, volume information is set in the range of minimum value 0 to maximum value 100 in each karaoke device 1, and 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 request for volume information (volume request) by sending volume information of 0.

[0050] 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).

[0051] 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 transmits 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 have 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).

[0052] Thereafter, similar to steps S104 and S105 in the first embodiment, the request unit 22 of one 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).

[0053] Also, similar to step S106 in the first embodiment, the recommendation unit 23 of one karaoke device 1a recommends to the user, based on the acquired song ID, song B (recommended song) that is being played on the karaoke device 1b to be recommended (step S208).

[0054] 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 the volume information of the karaoke performance to another karaoke device 1, acquires the 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.

[0055] 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 sound heard in the first room. [Variations]

[0056] In the above second embodiment, an example was described in which the control unit 10 of the karaoke device 1 operates as an identification unit 21, making a volume request to other karaoke devices 1 and identifying the karaoke device 1 to be recommended based on volume information obtained from the other karaoke devices 1, and also operates as a request unit 22, making a song request to the karaoke device 1 to be recommended and obtaining song identification information (song ID) of the song being played karaoke from the karaoke device 1 to be recommended, but the present invention is not limited to this example.

[0057] As a modified example of the second embodiment, in the control unit 10 of the karaoke device 1, the identification unit 21 may be configured to also perform the function of the request unit 22. The identification unit 21 of the modified example 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.

[0058] For example, the identification unit 21 recognizes each of the other adjacent karaoke devices 1 based on the stored device ID, and transmits 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 acquire the volume information of the karaoke performance and the song ID of the song being played, and transmit the volume information and the song ID as a response to the karaoke device 1 that transmitted the song request.

[0059] 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, similar to the second embodiment, the identification unit 21 identifies a karaoke device 1 to be recommended that corresponds to the karaoke voice from among the other karaoke devices 1 based on the acquired volume information. Furthermore, the karaoke device 1 sets the song ID corresponding to the karaoke device 1 to be recommended, among the song IDs acquired from the other karaoke devices 1, as a recommended song to be recommended by the recommendation unit 23.

[0060] [Recommended behavior for modified example] Next, an example of a recommendation operation of the karaoke device 1 according to the modification of the second embodiment, which recommends a song 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.

[0061] 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).

[0062] 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 karaoke 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 have responded to the song request (step S304). The identification unit 21 then identifies the karaoke device 1b to be recommended that corresponds to the detected karaoke voice, based on the volume information of the other karaoke devices 1b and 1c (step S305).

[0063] The recommendation unit 23 of one karaoke device 1a recommends song B with song ID (*****B) corresponding to the karaoke device 1b to be recommended from among the song IDs acquired from the other karaoke devices 1b and 1c to the user as a recommended song (step S306).

[0064] As a result, according to the modified example of the second embodiment, the number of procedures for requests sent from the karaoke device 1 to each of the other karaoke devices 1 can be reduced.

[0065] In each of the above-described embodiments, an example has been described in which the karaoke system 100 is configured to have a plurality of karaoke devices 1 connected to each other in a communicative manner, but the present invention is not limited to this example, and the karaoke system 100 in other examples may be configured to have an external server in addition to a plurality of karaoke devices 1.
