<Embodiment>
The karaoke device 1 according to the embodiment will be described with reference to FIGS. 1 to 3. The karaoke device 1 is an example of a “karaoke system”.

== Karaoke device ==
The karaoke device 1 is a device for performing karaoke and for the user to sing karaoke. The karaoke device 1 is installed in each room of the karaoke store. As shown in FIG. 1, the karaoke device 1 includes a karaoke body 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50.

The speaker 20 is configured to emit sound based on the sound emitted signal from the karaoke main body 10. The display device 30 is configured to display an image or an image on the screen based on the signal from the karaoke body 10. The microphone 40 is configured to convert the user's voice (singing voice) into an analog voice signal and input it to the karaoke main body 10. The remote control device 50 is a device for performing various operations on the karaoke main body 10. The user can make a reservation for a karaoke song or the like by using the remote control device 50. On the display screen of the remote controller device 50, icons and the like for inputting instructions for various operations are displayed.

The karaoke body 10 performs various controls related to karaoke singing, such as performance control of the selected karaoke music, display control of lyrics and background images, and processing of audio signals input through the microphone 40. As shown in FIG. 1, the karaoke main body 10 includes a control unit 11, a communication unit 12, a storage unit 13, an acoustic processing unit 14, a display processing unit 15, and an operation unit 16. Each configuration is connected to bus B via an interface (not shown).

The control unit 11 includes a CPU 11a and a memory 11b. The CPU 11a realizes various control functions by executing an operation program stored in the memory 11b. The memory 11b is a storage device that stores a program to be executed in the CPU 11a and temporarily stores various information when the program is executed.

The communication unit 12 provides an interface for connecting the karaoke body 10 to the communication line via a router (not shown). In addition, the communication unit 12 according to the present embodiment also functions as an interface for establishing wireless communication (for example, Bluetooth (registered trademark) communication or infrared communication) with the mobile terminal M of the service provider.

Application software for establishing communication with the karaoke device 1 is downloaded to the mobile terminal M. By bringing the mobile terminal M closer to the karaoke device 1 with the application software running, communication can be established between the mobile terminal M and the karaoke device 1 (details will be described later).

The storage unit 13 is a large-capacity storage device that stores various types of data, such as a hard disk drive.

The storage unit 13 stores a plurality of music data. The music data is data for performing karaoke performance by the karaoke device 1. When the karaoke device 1 plays the music based on the music data, the user can sing karaoke.

Based on the control of the control unit 11, the sound processing unit 14 controls the performance of the karaoke music and processes the audio signal input through the microphone 40. The sound processing unit 14 includes, for example, a MIDI sound source, a mixer, and an amplifier (none of which are shown). The MIDI sound source generates a musical tone signal based on the music data. The mixer mixes the music signal and the audio signal output from the microphone 40 at an appropriate ratio and outputs the mixture to the amplifier. The amplifier amplifies the mixing signal from the mixer and outputs it to the speaker 20 as a sound emission signal. As a result, the karaoke performance sound based on the sound emission signal and the singing sound from the microphone 40 are emitted from the speaker 20.

The display processing unit 15 performs processing related to various displays in the display device 30 and the remote control device 50 based on the control of the control unit 11.

Output. The control unit 11 detects the operation signal from the operation unit 16 and executes the corresponding process.

(Software configuration)
FIG. 2 is a diagram showing a software configuration example of the karaoke main body 10. The karaoke body 10 includes a communication processing unit 100, a volume measuring unit 200, a singing volume determining unit 300, and a performance control unit 400. The communication processing unit 100, the volume measurement unit 200, the singing volume determination unit 300, and the performance control unit 400 are realized by the CPU 11a executing a program stored in the memory 11b.

[Communication processing unit]
The communication processing unit 100 establishes communication with the mobile terminal M possessed by the service provider via the communication unit 12.

For example, the communication processing unit 100 transmits a connection request message via the communication unit 12 and searches for whether or not the mobile terminal M in the reception standby state exists in the room in which the karaoke device 1 is installed.

On the other hand, dedicated application software is pre-installed on the mobile terminal M owned by the service provider. When the service provider provides food and drink, he / she enters the room in which the order is received while holding the mobile terminal M in the state where the application software is started.

When the service provider enters the room in which the order is received, the mobile terminal M can receive the connection request message from the communication processing unit 100. In this case, the mobile terminal M transmits a confirmation signal indicating that the service provider is the mobile terminal M to the karaoke device 1. When the communication processing unit 100 receives the confirmation signal via the communication unit 12, the communication processing unit 100 establishes communication between the karaoke device 1 and the mobile terminal M according to a predetermined protocol (for example, the Bluetooth protocol). The communication processing unit 100 transmits a connection request message at predetermined time intervals, and determines whether communication is established or canceled depending on whether or not a confirmation signal from the mobile terminal M can be received. The communication unit 12 and the communication processing unit 100 are examples of the “communication control unit”.

When the communication between the karaoke device 1 and the mobile terminal M is established, the communication processing unit 100 outputs a signal to the effect that the communication has been established to the singing volume determination unit 300.

[Volume measurement unit]
The volume measuring unit 200 measures the singing volume when a karaoke performance is being performed.

Specifically, the volume measuring unit 200 determines whether or not a karaoke performance is being performed. Whether or not the karaoke performance is performed is performed, for example, by confirming whether or not the sound processing unit 14 is executing the performance processing of the karaoke music.

When it is determined that the karaoke performance is being performed, the volume measuring unit 200 starts measuring the singing volume. The singing volume is measured, for example, as the strength of the audio signal input through the microphone 40. The measurement of the singing volume may be performed continuously or at predetermined intervals (for example, every second). The volume measuring unit 200 outputs the measurement result to the singing volume determining unit 300. If it is determined that the karaoke performance is not performed, the volume measuring unit 200 does not measure the singing volume.

The measurement of the singing volume may be started from the beginning of the karaoke performance (karaoke singing), or may be started when the communication between the mobile terminal M and the karaoke device 2 is established. In the latter case, the communication processing unit 100 also outputs a signal to the effect that communication has been established to the volume measuring unit 200. The volume measuring unit 200 starts measuring the singing volume when the signal is input.

Further, when the user himself / herself interrupts the karaoke singing due to the service provider entering the room or the like, there is no audio signal input through the microphone 40. In this case, the volume measuring unit 200 outputs a measurement result indicating that the measured value is 0 to the singing volume determining unit 300.

[Singing volume judgment unit]
When the communication between the mobile terminal M and the karaoke device 1 is established and the singing section is in the singing section, the singing volume determination unit 300 determines whether or not the measured singing volume is equal to or less than a predetermined value.

For users who hesitate to sing in front of strangers, when the service provider enters the room, karaoke singing tends to be interrupted or the voice becomes quieter. The singing volume in this case is smaller (or 0) than the singing volume of general karaoke singing. Therefore, when the singing volume measured by the volume measuring unit 200 is equal to or less than a predetermined value in the state where the communication is established, it can be determined that the singing volume has decreased due to the entry of the service provider.

On the other hand, a karaoke song has a section in which karaoke singing is performed (singing section) and a section in which karaoke singing is not performed (non-singing section such as an interlude part). In the non-singing section, there is no input of singing voice from the microphone 40. Therefore, it is necessary to judge the singing volume in the singing section.

Therefore, the singing volume determination unit 300 receives an input of a signal indicating that communication between the mobile terminal M and the karaoke device 1 has been established, and determines whether or not the song is currently being karaoke. A known method can be used to determine the singing section. For example, the singing volume determination unit 300 determines that the singing section is during the time when the guide melody is being pronounced, while the singing is being scored, or while the lyrics image is being color-changed, and during other periods ( Prelude, interlude, lyric, etc.) can be judged as non-singing period. In addition, a mark indicating a singing section such as A melody, B melody, and chorus is added in advance in the music data. The singing volume determination unit 300 can determine whether or not it is a singing section by referring to the mark.

When communication is established and it is a singing section, the singing volume determination unit 300 determines whether or not the singing volume input in time series from the volume measuring unit 200 is equal to or less than a predetermined value.

Various values can be used as the predetermined value. For example, it is possible to use the average value of the singing volume in general karaoke singing, the singing volume (or the average value thereof) obtained when another person sings the same karaoke song in karaoke.

Alternatively, depending on the personality of the user, the original singing volume may be low regardless of the presence or absence of a clerk, or conversely, the original singing volume may be high. When the average value of the singing volume in general karaoke singing is used as the predetermined value for the user whose original singing volume is low, the singing volume becomes lower than the average value even if there is no hesitation due to the clerk entering the room, and the performance is performed. It may be interrupted (details will be described later). On the other hand, when the average value of the singing volume in general karaoke singing is used as a predetermined value for a user whose original singing volume is high, even if the singing volume is lowered due to the entry of a clerk, the general singing volume It becomes a value larger than the average value, and there is a possibility that the place where the performance should be interrupted is not interrupted.

In consideration of such a case, it is also possible to use the time-series singing volume obtained when the user sings the same song in the past as a predetermined value. The value of the singing volume obtained in such past karaoke singing can be associated with the music ID and the user ID and stored in a storage unit or the like of a server (not shown).

Further, as a predetermined value, the singing volume of the section sung from the start of the current karaoke singing until the communication is established (the value of each section or the average value may be used) can also be used. By using such a predetermined value, even a user who has never sung the same song in the past can make a judgment according to his / her personality.

When the singing volume is equal to or less than a predetermined value, the singing volume determination unit 300 outputs a signal to that effect to the performance control unit 400.

[Performance control unit]
The performance control unit 400 performs various controls related to the performance of the karaoke music on the karaoke device 1. For example, the performance control unit 400 controls the sound processing unit 14 to execute the performance of the karaoke music selected by the user.

(Interruption of karaoke performance)
Here, the performance control unit 400 according to the present embodiment controls the sound processing unit 14 when the singing volume is equal to or less than a predetermined value, and interrupts the karaoke performance currently being performed.

The performance control unit 400 stores the performance position at which the karaoke performance is interrupted. The performance position where the karaoke performance is interrupted can be specified as, for example, information indicating a section or information indicating a musical note in the karaoke music. The "interruption" in the present embodiment also includes the use of the pause function mounted on the karaoke device 1 and the so-called "fade out" in which the volume of the karaoke performance is gradually lowered.

(Resume karaoke performance)
Further, the performance control unit 400 according to the present embodiment restarts the karaoke performance when the communication with the mobile terminal M is canceled.

Even a user who interrupts karaoke singing due to the entry of the service provider can perform karaoke singing as usual after the service provider leaves the room.

Therefore, the performance control unit 400 restarts the karaoke performance when the service provider leaves the room.

Specifically, the communication processing unit 100 cannot receive the confirmation signal from the mobile terminal M when the service provider leaves the room. In this case, the communication processing unit 100 determines that the communication with the mobile terminal M has been canceled. The communication processing unit 100 outputs a release signal to the effect that the communication has been canceled to the performance control unit 400.

When the performance control unit 400 receives the release signal, the performance control unit 400 restarts the interrupted karaoke performance. The resumption of the karaoke performance can be started from the performance position where the memorized karaoke performance was interrupted.

Alternatively, when restarting the karaoke performance, the performance control unit 400 can restart the performance from a predetermined position before the performance position where the karaoke performance was interrupted.

As described above, the karaoke performance is interrupted when the singing volume is equal to or less than a predetermined value. Here, when the singing volume is equal to or less than the predetermined value, as a result, the user cannot enjoy karaoke singing from the time when the singing volume becomes equal to or less than the predetermined value. On the other hand, the performance position where the karaoke performance is interrupted is a position where a predetermined time has elapsed from the time when the karaoke singing can no longer be enjoyed (when the service provider enters the room).

Therefore, if the performance is resumed from the performance position where the karaoke performance was interrupted, there is no opportunity to sing enough karaoke during the period from the time when the singing volume becomes below the predetermined value until the karaoke performance is interrupted. Can't enjoy karaoke singing.

Therefore, the performance control unit 400 restarts the performance from a predetermined position prior to the performance position where the karaoke performance was interrupted. Therefore, the user can perform karaoke singing again for the period from the time when the singing volume becomes equal to or lower than the predetermined value until the karaoke performance is interrupted.

The predetermined position is, for example, a performance position specified based on the time from the time when the singing volume becomes equal to or lower than the predetermined value until the karaoke performance is interrupted (the position returned by the time from the interrupted performance position). Alternatively, an arbitrary position (for example, one bar before the measure including the interrupted playing position) can be set in advance.

== About the operation of the karaoke device 1 ==
Next, a specific example of the operation of the karaoke device 1 in the present embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing an operation example of the karaoke device 1. In this example, it is assumed that the user of the karaoke device 1 has ordered food and drink in advance. Further, it is assumed that the application software for establishing communication with the karaoke device 1 has been launched in advance in the mobile terminal M possessed by the service provider that provides food and drink. Further, it is assumed that the karaoke performance of the music reserved by the user is being performed.

The user sings karaoke along with the karaoke performance. The volume measuring unit 200 measures the singing volume (measurement of the singing volume. Step 10). The measured volume is appropriately output to the performance control unit 400.

The communication processing unit 100 transmits a connection request message to the room in which the karaoke device 1 is installed via the communication unit 12 (connection request. Step 11).

When the service provider enters the room and the mobile terminal M receives the connection request message transmitted in step 11, the mobile terminal M transmits a confirmation signal indicating that it is a clerk to the communication processing unit 100.

When the confirmation signal is received (Y in step 12), the communication processing unit 100 establishes communication with the mobile terminal M (establishment of communication, step 13).

When the communication between the mobile terminal M and the karaoke device 1 is established and the singing section is in the singing section, the singing volume determining unit 300 determines whether or not the measured singing volume is equal to or less than a predetermined value (determining the singing volume). Step 14).

When the measured singing volume is equal to or lower than a predetermined value (Y in step 15), the performance control unit 400 interrupts the karaoke performance (interruption of the karaoke performance, step 16).

The communication processing unit 100 confirms the connection status with the mobile terminal M. When the communication with the mobile terminal M is canceled (in the case of Y in step 17), the performance control unit 400 resumes the karaoke performance interrupted in step 16 (restart of the karaoke performance. Step 18).

As described above, according to the karaoke device 1 according to the present embodiment, by referring to the singing volume of the karaoke singing, the karaoke performance is interrupted when the service provider enters the room, and the karaoke is performed after the service provider leaves the room. You can resume playing. That is, according to the karaoke device 1 according to the present embodiment, it is possible to perform karaoke performance according to the personality of the user.
