As shown in FIG. 1, the karaoke apparatus K is capable of communicating with a ventilation system V installed in a karaoke room R. The ventilation system V ventilates the inside of the karaoke room R. The ventilation system V is not particularly limited as long as it is a system that can ventilate a closed space. On the other hand, a typical karaoke room requires high sound insulation. Therefore, it is preferable that the ventilation system V is a system capable of first-class ventilation in which air supply and exhaust are performed mechanically.

As shown in FIG. 2, the karaoke apparatus K includes a karaoke main body 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50.

The karaoke main body 10 performs various controls related to karaoke performance and karaoke singing, such as controlling the performance of selected songs, controlling the display of lyrics and background images, and processing audio signals input through the microphone 40. The speaker 20 is configured to emit sound based on a signal from the karaoke main body 10. The display device 30 is configured to display videos and images on a screen based on signals from the karaoke main body 10. The display device 30 is an example of "display means". The microphone 40 is configured to convert the singing voice based on the user's karaoke singing into an analog audio 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.

As shown in FIG. 3, the karaoke main body 10 includes a storage means 10a, a communication means 10b, an input means 10c, a performance means 10d, and a control means 10e. Each component is connected to bus B via an interface (not shown).

[Storage means]
The storage means 10a is a large capacity storage device that stores various data, and is, for example, a hard disk drive. The storage means 10a stores music data.

The song data is given song identification information for identifying each song. The song identification information is information unique to each song, such as a song ID for identifying the song. The music data includes accompaniment data, reference data, and the like. The accompaniment data is the source data of the karaoke performance sound. The reference data is data for scoring karaoke singing by users.

The storage unit 10a stores lyrics caption data for displaying lyrics captions corresponding to each song on the display device 30 etc. in time with the karaoke performance, background video data such as a background video displayed on the display device 30 etc. during the karaoke performance, and stores attribute information of the song. The attribute information according to this embodiment includes the performance time of the song. Note that the performance time may be included in the music data.

[Communication means/input means]
The communication means 10b provides an interface for communicating with the remote control device 50 and the ventilation system V. The input means 10c is configured for the user to input various instructions. The input means 10c is a button or the like provided on the karaoke main body 10. Alternatively, the remote control device 50 may function as the input means 10c.

[Means of performance]
The performance means 10d performs karaoke performance of songs and processes signals based on singing voices input through the microphone 40 under the control of the control means 10e. The performance means 10d includes a sound source, a mixer, an amplifier, etc. (none of which are shown).

[Control means]
The control means 10e performs various controls in the karaoke apparatus K. The control means 10e includes a CPU and a memory (both not shown). The CPU implements various functions by executing programs stored in memory.

In this embodiment, the CPU executes a program stored in the memory, so that the control means 10e controls the first reservation section 100, the performance control section 200, the calculation section 300, the determination section 400, and the second reservation section 500. , and functions as a system control unit 600.

(First reservation section)
The first reservation unit 100 makes a reservation for the performance of a piece of music by registering the piece of music selected by the user in a reservation queue.

For example, the user U of the karaoke device K operates the remote control device 50 to select a song X1 that he/she desires to sing at karaoke. The first reservation unit 100 makes a performance reservation for the music piece X1 by registering the music ID of the music piece X1 selected by the user U in the reservation queue of the storage unit 10a. It is assumed that the user U subsequently selects the song X2 consecutively. In this case, the first reservation unit 100 reserves the performance of the song X2 by registering the song ID of the song X2 in the reservation queue following the song ID of the song X1. That is, the first reservation unit 100 registers the song IDs in the reservation queue in the order in which the users select the songs. In addition, although the case where the number of users of the karaoke apparatus K is one is demonstrated below, the number of users may be plural.

(Performance control section)
The performance control section 200 controls the performance of music.

For example, in response to a user inputting an instruction to start a performance via the remote control device 50, the performance control unit 200 stores the accompaniment data of the corresponding song in the storage device based on the song ID registered in the reservation queue. 10a. Then, the performance control unit 200 outputs the acquired accompaniment data to the performance means 10d to perform a karaoke performance.

(Calculation section)
The calculation unit 300 calculates the total performance time, which is the total performance time of each song registered in the reservation queue by the first reservation unit 100.

The calculation unit 300 calculates the total performance time every time a song is reserved in the reservation queue by the first reservation unit 100. For example, when the song X1 is first registered in the reservation queue, the calculation unit 300 refers to the attribute information of the song X1 and obtains the performance time T1 of the song X1. In this case, the calculation unit 300 calculates the performance time T1 as the total performance time ST1.

Next, when the song X2 is registered in the reservation queue, the calculation unit 300 refers to the attribute information of the song X2 and obtains the performance time T2 of the song X1. The calculation unit 300 adds the performance time T2 to the performance time T1 to calculate the total performance time ST2.

Similarly, when the song X3 is registered in the reservation queue, the calculation unit 300 refers to the attribute information of the song X3 and obtains the performance time T3 of the song X3. The calculation unit 300 adds the performance time T3 to the performance time T1 and the performance time T2 (ie, the total performance time ST2) to calculate the total performance time ST3. When the song X4 is registered in the reservation queue, the calculation unit 300 refers to the attribute information of the song X4 and obtains the performance time T4 of the song X4. The calculation unit 300 adds the performance time T4 to the performance time T1, the performance time T2, and the performance time T3 (ie, the total performance time ST3) to calculate the total performance time ST4.

Note that instead of acquiring the performance time included in the attribute information, the calculation unit 300 may use the performance time determined from the music data (for example, the structure and tempo of the music data). Further, the calculation unit 300 may obtain the performance time by referring to a table that associates music pieces (music IDs) and performance times, which is stored in advance in the storage unit 10a.

(Judgment Department)
The determination unit 400 determines whether the total performance time satisfies a predetermined condition.

The predetermined conditions are criteria for determining whether or not to ventilate the karaoke room R. As the predetermined conditions, one standard that takes into consideration the size of the karaoke room R, etc. is set in advance. For example, the predetermined condition can be a time period such as "15 minutes or more."

The determination unit 400 performs determination every time the total performance time is calculated. The determination unit 400 outputs the determination result to the second reservation unit 500.

For example, assume that the calculation unit 300 calculates the total performance time ST1. The determination unit 400 determines whether the total performance time ST1 satisfies a predetermined condition CT. The determination unit 400 outputs the determination result J1 to the second reservation unit 500. Similarly, it is assumed that the calculation unit 300 calculates the total performance time ST2. The determination unit 400 determines whether the total performance time ST2 satisfies a predetermined condition CT. The determination unit 400 outputs the determination result J2 to the second reservation unit 500. Assume that the calculation unit 300 calculates the total performance time ST3. The determination unit 400 determines whether the total performance time ST3 satisfies a predetermined condition CT. The determination unit 400 outputs the determination result J3 to the second reservation unit 500. Assume that the calculation unit 300 calculates the total performance time ST4. The determination unit 400 determines whether the total performance time ST4 satisfies a predetermined condition CT. The determination unit 400 outputs the determination result J4 to the second reservation unit 500.

In the following explanation, determination results J1 to J3 indicate that "the total performance time does not meet the predetermined time", while determination result J4 indicates that "the total performance time satisfies the predetermined time". shall be.

(Second reservation section)
When the total performance time satisfies a predetermined condition, the second reservation unit 500 registers the preset ventilation music in the reservation queue and resets the total performance time.

The ventilation music is at least one of the plurality of music pieces stored in the storage means 10a. The ventilation music may be selected from songs that can be sung at karaoke, or may be a song prepared separately from the songs that can be sung at karaoke (for example, a BGM song without lyrics). The ventilation music is selected according to the performance of the ventilation system V, etc., and has a performance time that allows sufficient time for ventilation.

In the above example, when the determination result J4 is input, the second reservation unit 500 reads the music ID of the ventilation music VM from the storage means 10a and registers it in the reservation queue, thereby reserving the performance of the ventilation music VM. . In this case, the ventilation music VM will be scheduled to be performed after the music X4.

After registering the ventilation music VM in the reservation queue, the second reservation unit 500 resets the total performance time ST4 of the songs X1 to X4 that have been reserved for performance up to that point. Therefore, for example, when a new song X5 is registered in the reservation queue after the ventilation song VM is reserved, the calculation unit 300 refers to the attribute information of the song X5 and obtains the performance time T5 of the song X5. . In this case, the calculation unit 300 newly calculates the performance time T5 as the total performance time ST5.

On the other hand, when the determination results J1 to J3 are input, the second reservation unit 500 does not execute any special processing because the total performance time does not satisfy the predetermined time.

Note that the determination section 400 may output the determination result to the second reservation section 500 only when "the total performance time satisfies the predetermined time". In this case, the second reservation unit 500 registers the ventilation music in the reservation queue according to the input of the determination result, and resets the total performance time.

(System control unit)
The system control unit 600 operates the ventilation system V during the karaoke performance of the ventilation music by the performance means 10d.

For example, assume that songs X1 to X4, ventilation song VM, and song X5 are registered in the reservation queue in this order.

The performance control section 200 controls the performance means 10d in response to a user's input of an instruction to start a performance, and causes the karaoke performance to be performed in order from song X1.

The system control unit 600 does not perform any special processing during the karaoke performance of songs X1 to X4. On the other hand, the system control unit 600 transmits a drive start signal to the ventilation system V in accordance with the start of the karaoke performance of the ventilation music VM. The ventilation system V starts ventilation in the karaoke room R based on the signal. Thereafter, the system control unit 600 transmits a drive stop signal to the ventilation system V at the end of the karaoke performance of the ventilation music VM. The ventilation system V stops ventilation in the karaoke room R based on the signal. After the karaoke performance of the ventilation music VM ends, the performance control unit 200 controls the performance means 10d to perform the karaoke performance of the music X5.

==About processing in karaoke equipment==
Next, processing in the karaoke apparatus K according to this embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing the processing in the karaoke apparatus K. Note that the karaoke apparatus K can communicate with a ventilation system V installed in the karaoke room R.

The first reservation unit 100 makes a performance reservation for a music piece by registering the music piece selected by the user in a reservation queue (music performance reservation. Step 10).

The calculation unit 300 calculates the total performance time of the songs registered in the reservation queue by the first reservation unit 100 (calculate the total performance time. Step 11).

The determination unit 400 determines whether the total performance time calculated in step 11 satisfies a predetermined condition.

If the total performance time satisfies the predetermined condition (Y in step 12), the second reservation unit 500 registers the preset ventilation music in the reservation queue (reservation for performance of the ventilation music. Step 13) After that, the second reservation unit 500 resets the total performance time calculated in step 11 (resetting the total performance time, step 14).

When the user inputs an instruction to start the performance (Y in step 15), the performance control unit 200 controls the performance means 10d to start karaoke performance of the songs in the order registered in the reservation queue. do.

Here, when the karaoke performance of the ventilation music is started (Y in step 16), the system control unit 600 starts the operation of the ventilation system V (start of operation of the ventilation system. Step 17). Thereafter, when the karaoke performance of the ventilation music ends, the system control unit 600 ends the operation of the ventilation system V (end of the operation of the ventilation system. Step 18).

The karaoke apparatus K repeatedly performs the processes from step 10 to step 18 until the user finishes using the karaoke apparatus K (until Y in step 19).

As is clear from the above, the karaoke apparatus K according to the present embodiment can communicate with the ventilation system V installed in the karaoke room R. The karaoke device K includes a first reservation section 100 that reserves the performance of a song by registering the song selected by the user in the reservation queue, and a first reservation section 100 that makes a reservation for the performance of the song by registering the song selected by the user in the reservation queue. A calculation section 300 calculates the total performance time, which is the sum of the performance times for each performance time; a determination section 400 determines whether the total performance time satisfies a predetermined condition; a second reservation unit 500 that registers the ventilation music being played in the reservation queue and resets the total performance time; and a system control unit 600 that operates the ventilation system V during the karaoke performance of the ventilation music by the performance means 10d. have

According to such a karaoke apparatus K, the karaoke room R is automatically ventilated at an appropriate timing even if a plurality of songs are reserved for performance. Therefore, the user can always perform karaoke singing in a comfortable environment. That is, according to the karaoke apparatus K according to the present embodiment, the inside of the karaoke room can be ventilated depending on the karaoke singing situation.

Note that a plurality of ventilation music pieces may be set. In this case, the second reservation unit 500 can select ventilation songs in a predetermined order or randomly and register them in the reservation queue. Further, if the karaoke device K is used for a long time at one time, the performance of the ventilation music will be reserved multiple times. In this case, the second reservation unit 500 may always register the same ventilation music in the reservation queue, or may register different ventilation music in the reservation queue.

Further, as long as sufficient time can be secured for one ventilation, the number of ventilation songs scheduled to be performed for one ventilation is not limited to one song. For example, it is assumed that a ventilation music VM1 with a performance time of 5 minutes and a ventilation music VM with a performance time of 6 minutes are set. It is also assumed that 10 minutes is sufficient time. In this case, in the above example, the second reservation unit 500 can reserve the performance of the ventilation music VM1 and the ventilation music VM2 between the reservations of the music X4 and the music X5.

Furthermore, the performance control unit 200 may control the performance means 10d to emit the sound at a volume of the karaoke performance of the ventilation music lower than the volume of the normal karaoke performance. In this case, ventilation efficiency can be increased by opening the doors and windows of karaoke room R.

Furthermore, reservations for songs registered in the reservation queue may be canceled. In this case, the calculation unit 300 recalculates the total performance time based on the cancellation of the reservation (that is, subtracts the performance time of the canceled song from the already calculated total performance time). The determination unit 400 determines whether the recalculated total performance time satisfies a predetermined condition.

Further, the system control unit 600 can cause the display device 30 to display a message that the karaoke room R is being ventilated during the karaoke performance of the ventilation music.

<Modification 1>
The timing of ventilation of the karaoke room is preferably changed depending on the number of users using the karaoke room.

As shown in FIG. 5, in this modification, the CPU executes a program stored in the memory, so that the control means 10e controls the first reservation section 100, the performance control section 200, the calculation section 300, and the determination section 400. , a second reservation section 500, a system control section 600, and an acquisition section 700.

(Acquisition Department)
The acquisition unit 700 acquires the number of users who use the karaoke apparatus K.

The number of people can be obtained in various ways. For example, a photographing means is provided in the karaoke room R. The acquisition unit 700 can acquire the number of users in the karaoke room R by analyzing the video output from the photographing means using a known method. Alternatively, the acquisition unit 700 can acquire the number of users based on the login information of users who have logged in to the karaoke apparatus K.

(Judgment Department)
The determination unit 400 according to this modification changes the predetermined condition according to the obtained number of users.

Preferably, the predetermined conditions are changed so that the ventilation music is scheduled to be played sooner as the number of users increases. That is, it is preferable that the time indicated by the predetermined condition becomes shorter as the number of users increases.

For example, assume that a predetermined condition CT1 of "15 minutes or more" is set in advance. Here, when the number of people acquired by the acquisition unit 700 is one, the determination unit 400 determines whether the total performance time satisfies the predetermined condition CT1.

On the other hand, when the number of people acquired by the acquisition unit 700 is two, the determination unit 400 changes the predetermined condition CT1 to a predetermined condition CT2 of “13 minutes or more”. The determination unit 400 determines whether the total performance time satisfies a predetermined condition CT2. Alternatively, when the number of people acquired by the acquisition unit 700 is three, the determination unit 400 changes the predetermined condition CT1 to a predetermined condition CT3 of “11 minutes or more”. The determination unit 400 determines whether the total performance time satisfies a predetermined condition CT3.

As is clear from the above, the karaoke apparatus K according to this modification includes an acquisition unit 700 that acquires the number of users who use the karaoke apparatus K. The determination unit 400 changes the predetermined conditions according to the obtained number of users. According to such a karaoke apparatus K, the inside of the karaoke room can be ventilated according to the karaoke singing situation and the number of users.

<Modification 2>
It is more preferable not to perform karaoke singing while the karaoke room is being ventilated. The system control unit 600 in this modification controls the performance means 10d to prohibit the emission of sound based on the audio signal when an audio signal is input through the microphone 40 during the karaoke performance of ventilation music. .

For example, suppose that user U, who does not know that the karaoke room R is being ventilated, tries to sing karaoke along with the karaoke performance of ventilation music VM. In this case, an audio signal is input to the karaoke apparatus K via the microphone 40.

On the other hand, the system control unit 600 controls the performance means 10d to prohibit the emission of sound based on the audio signal. The performance means 10d outputs a performance signal of the ventilation music VM to the speaker 20, but does not output an audio signal. Therefore, only the karaoke performance sound of the ventilation music VM is emitted from the speaker 20, and the singing sound is not emitted.

As is clear from the above, when an audio signal is input via the microphone 40 during the karaoke performance of ventilation music, the system control unit 600 of the karaoke apparatus K according to the present modification is configured to control the system control unit 600 of the karaoke apparatus K according to the present modification, when an audio signal is input via the microphone 40 during the karaoke performance of ventilation music, the system control unit 600 controls the The performance means 10d is controlled to prohibit sound emission. According to such a karaoke apparatus K, a user who wants to sing karaoke can easily be made aware that the karaoke room R is being ventilated.

<Second embodiment>

Specifically, when the karaoke performance of the ventilation music VM starts, the system control unit 600 displays a message recommending sterilization of the microphone 40 (for example, "Please set the microphone in the microphone sterilizer") on the display device 30. Display it on the display screen. The system control unit 600 also transmits a signal to the microphone sterilizer S to start driving. The microphone sterilizer S starts operating based on the signal. When the user who has seen the message sets the microphone 40 in the microphone sterilizer S, the microphone sterilizer S sterilizes the microphone 40.

On the other hand, when the karaoke performance of the ventilation music VM ends, the system control unit 600 ends the display of the message. Furthermore, the system control unit 600 transmits a signal to the microphone sterilizer S to stop driving. The microphone sterilizer S ends its operation based on the signal.

In this embodiment, it is preferable that the ventilation music VM has a performance time longer than the time required for the sterilization process by the microphone sterilizer S.

==About processing in karaoke equipment==
Next, processing in the karaoke apparatus K according to this embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing the processing in the karaoke apparatus K. Note that the karaoke apparatus K can communicate with a ventilation system V installed in the karaoke room R. Furthermore, a microphone sterilizer S is connected to the karaoke machine K.

Steps 20 to 27 are similar to steps 10 to 27 in the first embodiment.

The system control unit 600 causes the display device 30 to display a message recommending sterilization of the microphone 40, and starts the operation of the microphone sterilizer S (message display and operation of the microphone sterilizer S starts. Step 28). Karaoke device K can execute step 27 and step 28 in parallel.

Thereafter, when the karaoke performance of the ventilation music ends, the system control unit 600 ends the operation of the ventilation system V (end of the operation of the ventilation system. Step 29). Further, the system control unit 600 ends the display of the message recommending sterilization of the microphone 40, and ends the operation of the microphone sterilizer S (message display ends, operation of the microphone sterilizer ends. Step 30). Karaoke device K can execute step 29 and step 30 in parallel.

The karaoke apparatus K repeatedly performs the processes from step 20 to step 30 until the user finishes using the karaoke apparatus K (until Y in step 31).

As is clear from the above, the system control unit 600 in the karaoke device K according to the present embodiment causes the display device 30 to display a message recommending sterilization of the microphone 40 during the karaoke performance of ventilation music, and also causes the karaoke device K to display a message recommending sterilization of the microphone 40.
