  Here, FIG. 2 shows an explanatory view of the arrangement of the karaoke system in FIG. 1 in the vehicle. In FIG. 2, for example, the passenger car 41 has four seats, and the position where the handle 42 is located is the driver's seat. For example, a karaoke performance device 12 is provided in front of the passenger car 41, and a display unit 13 is disposed in the vicinity thereof. Moreover, the speaker 16 is arrange | positioned ahead (back or front and back). Furthermore, a remote control device 17 is placed in the vehicle.

  And each input terminal M1-M4 which comprises the microphone input terminal 14 to which connection of microphone 15A-15D with which microphone ID was linked | related with each side corresponding to each seat becomes exclusive, respectively is arrange | positioned. The arrangement of the input terminals M1 to M4 may be, for example, a ceiling or a seat portion (a backrest, a headrest, an armrest, a dashboard for a front seat, a backrest or a headrest for a front seat for a rear seat). .

  For example, the input terminal M1 for the front right seat (driver's seat), the input terminal M2 for the front left seat (passenger seat), the input terminal M3 for the rear right seat, and the input terminal for the rear left seat M4 is arranged. For example, a pin microphone 15A (mic ID “A”) that can be clipped is connected to the input terminal M1 of the driver's seat, and hand microphones 15B to 15D (microphone IDs “B” to “D” are connected to the input terminals M2 to M4, respectively. D ") is connected. In order to allow the user to identify the microphones 15A to 15D at the time of music reservation, for example, the pin microphone 15A has a “red” identification color, the hand microphone 15B has a “yellow” identification color, and the hand microphone 15C has “green”. The identification color of “blue” is assigned to each identification color of the hand microphone 15D.

FIG. 3A shows a case where a screen for music reservation is displayed on the display unit 13, and a predetermined passenger uses, for example, the display unit 13 (operation panel 33) of the music search means 26. When a song is selected by searching for a predetermined song by function or by searching for other passengers, for example, the song is displayed with a singer name, a song name, and the like, and the microphone 15A used by the singer on the screen is displayed. 15D is selected with the identification color CL. The identification color CL corresponds to the microphone IDs “A” to “D”.

  The selected music is registered in the reservation queue 24A formed in the RAM 24 by the reserved music registration means 35, as shown in FIG. Here, each reserved music is set to the default state, and a performance flag for performing music of all reserved columns in the reservation queue 24A is set to “1”, and the microphone ID other than the microphone ID of the determined use state microphone is set. The performance flag in the reserved column corresponding to the microphone ID of “1” is set to “1”. Then, the performance flag in the reservation queue is referred to when the performance starts.

  FIG. 4 shows a flowchart of the reserved music performance target process of FIG. 1, and FIG. 5 shows an explanatory diagram of the reserved music performance target process of FIG. In FIG. 4, as shown in FIG. 3, in the reserved music registration means 35, the music selected by the music search means 26 or from the history storage section 36 is reserved in the reservation queue 24A (all performance flags are “1”). It is assumed that it is registered and managed by.

  The input microphone is connected to the microphone (15A to 15D) in use, for example, in which the microphone switch is turned on among the microphones (15A to 15D) connected to the microphone input terminal 14. Detection is performed based on whether or not the terminals (M1 to M4) are energized, and the detected microphone IDs of the microphones (15A to 15D) in use are discriminated and transmitted to the musical piece specifying means 27 (step (S1)).

  For example, when only the driver's microphone 15A is in the use state, the input terminal M1 to which the microphone 15A is connected is detected by the use microphone discrimination means 31 based on the presence / absence of energization. The microphone ID “A” of the microphone 15 </ b> A is discriminated and sent to the performance music specifying means 27.

  In the performance music specifying means 27, the performance flag of the reserved column corresponding to the microphone ID other than the acquired microphone ID in the reservation queue 24A is collectively changed to “0” (S2). For example, as shown in FIG. 5A, among the reserved columns of the reservation queue 24A, the performance flags in the reserved columns of microphone IDs “B” to “D” other than the determined microphone ID “A” Are collectively changed to “0”.

  Therefore, the performance music specifying means 27 sequentially specifies only the music whose performance flag in the reservation queue is “1” in accordance with the start of the performance, extracts the corresponding music from the music DB 25, and extracts background video data and lyrics telop. The performance is performed by sending the data to the reproduction control unit 28 and sending the music song data to the music song output unit 29 (S3).

  The use microphone discrimination means 31 constantly monitors whether or not the microphone is in use depending on whether or not the microphone input terminals M1 to M4 are energized. In addition to the microphone 15A, for example, the microphone 15B is switched on. If the microphone 15B is detected while the input terminal M2 is energized, the microphone ID “B” of the microphone 15B is determined, and the performance music specifying means 27 reserves the microphone ID “B”. The performance flag of the column is collectively changed from “0” to “1” (S1, S2). That is, the reserved column of the microphone ID “B” that is not the performance target is restored to the performance target all at once. In this state, as shown in FIG. 5B, the performance flags in the reserved columns with the microphone IDs “A” and “B” are set to “1” and are set as performance targets (S3).

  Then, the process is repeated until all the music pieces whose performance flag is “1” in the reservation column of the reservation queue 24A are finished (S4). Note that when the microphone ID in the reservation column of the previous performance order is determined for the music being played and the performance flag is set to “1”, the reservation column of the played music is deleted. What is necessary is just to return to the music of the performance flag "1" with a young turn, and to make it play in order.

  In this way, it is possible to specify the corresponding music pieces of the entire reserved music piece as a performance target from the microphone IDs “A” to “D” of the microphones 15A to 15D in use, and use the microphones 15A to 15D in use. If the user does not want to sing the reserved music, the user can sing the reserved music by switching off the corresponding microphone. The intention can be reflected immediately, and these can be made possible with the existing essential tool of the karaoke system called the microphone.

  Next, FIG. 6 shows a block diagram of a second embodiment of the karaoke system according to the present invention. The in-vehicle karaoke system 11 shown in FIG. 6 includes a microphone receiving unit 37 including the use microphone discrimination means 31 instead of the microphone input terminal 14 and the use microphone discrimination means 31 described above. Wireless microphones 15A to 15D that transmit microphone IDs “A” to “D” are arranged as microphones. That is, the microphones 15 </ b> A to 15 </ b> D send the microphone IDs “A” to “D” to the microphone receiving unit 37 when the microphones 15 </ b> A to 15 </ b> D are in an operating state by being switched on. Other configurations are the same as those in FIG.

  The microphones 15 </ b> A to 15 </ b> D are dedicated to, for example, a user, and each carrier wave having a different frequency is transmitted as a microphone ID to the microphone receiving unit 37 when the microphones 15 </ b> A to 15 </ b> D are used by switching on. The microphone receiving unit 37 receives the carrier wave that is transmitted when the predetermined microphone among the predetermined microphones 15A to 15D is in a used state, so that the used microphone discriminating means 31 uses the carrier wave. The microphone IDs “A” to “D” are discriminated by the frequency of the carrier wave and transmitted to the performance music specifying means 27, and the singing voice signal from the corresponding microphone is transmitted to the mixing amplifier 30. And an electronic circuit.

  That is, when the microphone receiving unit 37 receives a carrier wave from the microphone in use, the microphone used in the microphone detection unit 31 detects the microphone in use from the carrier wave, and determines the microphone ID based on the frequency. As shown in FIG. 5, the specifying unit 27 collectively sets the performance flags in the reserved columns of microphone IDs other than the determined microphone ID to “0”, and plays all the songs with the performance flag “1” in order. It is something to be made.

  As described above, even if the microphone used is wireless, the corresponding music of the entire reserved music is played from the microphone IDs “A” to “D” of the microphones 15A to 15D in the same manner as above. It can be specified as a target, and since it can be determined whether or not the music is to be played depending on whether or not the microphones 15A to 15D are in use, the corresponding microphone is used when the user does not want to sing the reserved music. By switching off, the user is not played and the user's intention to sing can be reflected immediately, and these can be made possible with the existing essential tool of the karaoke system called a microphone.

  The karaoke system of the present invention can be used for karaoke systems installed in automobiles, trains, airplanes, and ships of private cars and commercial vehicles (trucks, buses, etc.) in addition to karaoke boxes.
