Description

  The present invention relates to an in-vehicle device, and is suitable for use in, for example, an application in which different types of music are individually provided via a plurality of speakers provided in each seat.

Conventionally, in-vehicle devices have a four-channel configuration in which speakers or headphones are installed in each of the driver's seat, the passenger seat, the rear right seat, and the rear left seat, depending on the audio unit installed in the vicinity of the driver seat. Some of the four types of reproduced music are individually output from these four speakers or headphones (see, for example, Patent Document 1).
JP2003-111199

  By the way, in the vehicle-mounted device with such a configuration, when different types of music according to the selection of the user seated in each seat are individually output from the headphones of each seat, each user is Since it is difficult to know what kind of music is being listened to, and because it is difficult to communicate between individual users because the music is being listened to through headphones, all users accidentally listen to the same music. Even if it is, it is not possible for all users to listen to the same music by switching from headphones to speakers.

  The present invention has been made in consideration of the above points, and when different types of content are individually provided to individual users via one of the plurality of first output means, When the content types match, the plurality of first output means is switched to the second output means to propose an in-vehicle device that can provide the same type of content to all individual users.

  In order to solve such a problem, in the in-vehicle device according to the present invention, one piece of content arbitrarily selected from a plurality of types by an individual user via one of a plurality of first output units, respectively. When outputting to each user individually, it is determined whether almost all of the individual users who receive the content receive the same content, and almost all of the plurality of users receive the same content. If it is determined, the plurality of first output means is switched to the second output means so that the same content is simultaneously provided to individual users.

  Thereby, when each individual user listens individually to one content arbitrarily selected from a plurality of types by each individual user via one of the plurality of first output means, respectively. When almost all of the individual users who receive the content are listening to the same content, the same content can be provided simultaneously by switching from the plurality of first output means to the second output means. When the content being listened to by the user is the same content, each user does not listen to and enjoy the same content individually through one of the plurality of first output means, but the second output Through the means, all the individual users can listen and enjoy the same content.

  According to the present invention, in the case of different types of content, each user can enjoy listening individually through one of a plurality of first output means, and in the case of the same content, the second It is possible to realize an in-vehicle device, a content providing method, and a content providing program that can be enjoyed by listening to all individual users from the output means.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Overall Configuration of In-Vehicle Audio System In FIG. 1, 1 indicates an in-vehicle audio system as an in-vehicle device of the present invention as a whole, for an audio main body 2 and a driver seat connected to the audio main body 2. Speaker 3 or driver's headphone 7, passenger's seat speaker 4 or passenger's headphone 8, rear right seat speaker 5 or rear right seat headphone 9, rear left seat speaker 6 or rear left seat headphone 10, The authentication management unit 50 is connected to the main body unit 2.

  In the in-vehicle audio system 1, whether music is output to a user seated in each seat via the driver's seat speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6, Alternatively, whether to output music to a user seated in each seat via the headphone 7 for the driver's seat, the headphone 8 for the passenger seat, the headphone 9 for the rear right seat, and the headphone 10 for the rear left seat is sitting in each seat. Determined by the user's will.

  The authentication management unit 50 includes a driver seat authentication unit 11 provided near the driver seat, a passenger seat authentication unit 21 provided near the passenger seat, a rear right seat authentication unit 31 and a rear left seat provided near the rear right seat. The rear left seat authentication unit 41 provided in the vicinity individually authenticates each user seated in each seat, and outputs the authentication result to the audio main unit 2 as the external key S1. ing.

  The driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31 and the rear left seat authentication unit 41 include button switch groups 12, 22, 32 having button switches from “1” to “4”, and For example, when a button switch “1” is registered by Mr. A who sits in the driver's seat, the driver's seat authentication indicates that the button switch “1” corresponds to Mr. A. The unit 11 can recognize and output the authentication result to the audio main unit 2 as the external key S1A.

  Similarly, when the button switch “2” is registered by Mr. B who is seated in the passenger seat, the passenger seat authentication unit 21 can recognize that the button switch “2” corresponds to the user B. The authentication result is output to the audio main unit 2 as the external key S1B.

  The rear right seat authentication unit 31 and the rear left seat authentication unit 41 are registered with a button switch “3” and a button switch “4” by Mr. C sitting on the rear right seat and Mr. D sitting on the rear left seat. In this case, it can be recognized that the button switch of “3” corresponds to Mr. C and the button switch of “4” corresponds to Mr. D, and the external keys S1C and S1D are obtained as authentication results, respectively. Output to 2.

  Accordingly, the authentication management unit 50 recognizes that the user is Mr. C and is seated in the driver's seat when the user presses the button switch “3” in the driver's seat authentication unit 11, for example. When S1C is output to the audio main unit 2 and the button switch “1” is pressed by a user in the rear right seat authentication unit 31, the user is Mr. A and is seated in the rear right seat. Recognizing this, the external key S1A is output to the audio main unit 2.

  Further, the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, and the rear left seat authentication unit 41 include a non-contact IC card receiving unit 13 for authenticating each of Mr. A to Mr. D, 23, 33 and 43 are provided, and each receiving unit 13, 23, 33 and 43 reads each non-contact IC card and recognizes the user ID (identification) of Mr. A to Mr. A. It is possible to individually recognize who is seated in which seat among Mr. D and from which speaker the music is provided.

  Further, the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, and the rear left seat authentication unit 41 are provided with display units 14, 24, 34, and 44, which are liquid crystal displays, and are being reproduced. By displaying the music name, the playback time, and other various contents, various information is notified to the seated user.

(2) Circuit Configuration of Audio Main Unit As shown in FIG. 2, the audio main unit 2 includes a CPU (Central Processing Unit) configuration microcomputer included in the output control unit 73 as a whole, and a ROM (not shown). By starting a basic program or application program (output control program or content providing program) stored in (Read Only Memory) on a RAM (Random Access Memory) (not shown), a normal audio playback function and output control processing described later Procedures are made to execute.

  Actually, the audio main unit 2 reproduces music data stored in the hard disk of the hard disk drive 61 built in the audio main unit 2 and sends the reproduction data to the data processing unit 63 via the memory 62. To do. The music data storage destination is not limited to a hard disk, but may be a CD (Compact Disc) or an MD (Mini Disc) or other various disc-shaped recording media such as a Blu-ray disc.

  Here, the hard disk drive 61 can play back music for four channels almost simultaneously by controlling the movement of the magnetic head at high speed, and a data processing unit 63 described later while buffering the playback data in the memory 62. , A speaker 3 for a driver's seat, a speaker 4 for a passenger seat, a speaker 5 for a rear right seat, and a speaker 6 for a rear left seat installed in an interior space via an audio signal generator 64, an electronic volume circuit 65 and amplifiers 66-69. By outputting from, the music for the four channels can be provided to A to D without interruption and almost simultaneously in parallel.

  The data processing unit 63 performs processing according to a predetermined format on the reproduction data, and sends the processing result to the audio signal generation unit 64. The audio signal generation unit 64 generates an audio signal corresponding to, for example, a preset concert mode, hall mode, or jazz mode, and sends it to the electronic volume circuit 65.

  The electronic volume circuit 65 outputs an audio signal to the amplifiers 66 to 69 under the control of the microcomputer 70. The electronic volume circuit 65 selects the radio reception signal and the audio signal selected by the tuner 71 according to the control of the microcomputer 70, and outputs the selected one to the amplifiers 66 to 69.

  The amplifiers 66 to 69 amplify the audio signals input from the electronic volume circuit 65, and respectively amplify them through the driver seat speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6. By outputting, music is provided to the user sitting in each seat. Note that the microcomputer 70 can also limit the output from the amplifiers 66 to 69 to the speakers 3 to 6 by controlling the mute circuit 72.

  Further, the microcomputer 70 responds to the external key S1 (S1A to S1D) supplied from the authentication management unit 50, the driver seat speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6. Which music is to be provided is determined, and an output control process to be described later is executed.

(3) Output Control Method Specifically, as shown in FIG. 3, the microcomputer 70 includes a driver seat speaker 3 and a passenger seat speaker via amplifiers 66 to 69 as a basic output control method (1). 4. The rear right seat speaker 5 and the rear left seat speaker 6 can all output an audio signal AD1 relating to the same music.

  In this case, the same music is provided from the driver seat speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6, so Mr. A who is seated in each seat All Mr. D can listen and enjoy the same music.

  The microcomputer 70 does not receive music from the driver's seat speaker 3, the passenger's seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6 by A to D, but for the driver's seat. When it is selected that the music is provided from the headphones 7, the passenger seat headphones 8, the rear right seat headphones 9 and the rear left seat headphones 10, the driver seat headphones 7 and the passenger seat headphones 8 are selected. The audio signal AD1 relating to the same music can be output from the rear right seat headphones 9 and the rear left seat headphones 10.

  As shown in FIG. 4, the microcomputer 70 receives the audio signal AD1 of the music from the driver's seat speaker 3 as shown in FIG. 3, for example, when Mr. A selects a different type of music. Outputs the audio signal AD2 of the selected different types of music from the driver seat speaker 3, and the passenger seat speaker 4, the rear right seat speaker 5 and the rear left seat speaker 6 are the same as before. The audio signal AD1 relating to the music is continuously output.

  By the way, Mr. A who was originally seated in the driver's seat changed his seat to replace driving with Mr. C who was seated in the rear right seat for a break, and Mr. A changed the rear right seat authentication unit 31 after the change. And when the user presses the button switch “3” in the driver seat authentication unit 11 after the change, or when the user A and C respectively change the rear right seat after the change. When the authentication unit 31 and the driver's seat authentication unit 11 place individual contactless IC cards on the reception unit 33 and the reception unit 13, the microcomputer indicates that the seat has changed between Mr. A and Mr. C. 70 is made to recognize.

  Specifically, the microcomputer 70 is in a state in which Mr. A can sit on the rear right seat and receive music from the rear right seat speaker 5, and Mr. C can sit on the driver seat and perform the driving. It is possible to recognize that the player can receive music from the seat speaker 3.

  As a result, as shown in FIG. 5, the microcomputer 70 changes the audio signal AD2 (FIG. 4) of the music that Mr. A has listened to so far to output from the rear right seat speaker 5, and the driver seat. The voice signal AD2 is returned to the voice signal AD1 from the driver speaker 3, and the voice signal AD1 can be changed to be output from the driver seat speaker 3, the passenger seat speaker 4, and the rear left seat speaker 6. Has been made.

  Subsequently, an output control processing procedure using the above-described output control methods (1) to (3) will be described below.

(3-1) Output Change Processing Procedure Based on Button Switch Pressing An output control processing procedure based on button switch pressing actually executed by the microcomputer 70 in accordance with the output destination control program stored in the ROM will be described with reference to the flowchart of FIG. Will be described in detail.

  When the power is turned on, the microcomputer 70 of the output control unit 73 in the audio main unit 2 enters from the start step of the routine RT1, and proceeds to step SP1.

  In step SP1, the microcomputer 70 uses the button switches 12, 22, 32, and 42 in the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, and the rear left seat authentication unit 41. If it is confirmed that the user registration corresponding to the button switch pressing operation is performed, the process proceeds to the next step SP2.

  In step SP2, the microcomputer 70 reproduces the music arbitrarily selected by each of A to D in each seat by the hard disk drive 61 almost simultaneously in parallel, and the driver seat speaker 3, the passenger seat speaker 4, Different music is provided from the rear right seat speaker 5 and the rear left seat speaker 6, respectively, and the process proceeds to the next step SP3.

  In step SP3, the microcomputer 70 changes the seats of the button switches 12, 22, 32, and 42 of the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, and the rear left seat authentication unit 41. It is determined whether or not the external keys S1A to S1D corresponding to the pressing are input when the key is pressed by any of A-D.

  If a negative result is obtained here, this means that none of the external keys S1A to S1D has been input, and all of Mr. A to D have not changed their seats. At this time, the microcomputer 70 Returns to step SP2 and continues to reproduce the music as before.

  On the other hand, if a positive result is obtained in step SP3, this means that there is a seat change among A to D, and the button switch of the number assigned to the user who changed the seat changes after the seat change. The driver's seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31 and the rear left seat authentication unit 41 are pressed and the corresponding external keys S1A to S1D are input. The microcomputer 70 proceeds to the next step SP4.

  In step SP4, the microcomputer 70 analyzes who the external keys S1A to S1D supplied from the authentication management unit 50 recognizes who has changed from Mr. A to Mr. D and moves to step SP5. .

  In step SP5, the microcomputer 70 stores in the memory 62 the type of music and the elapsed playback time output from the speaker of the original seat before the seat change. The output destination is changed by outputting the same music that was output from the speaker of the seat at the timing after the elapsed playback time, and the process returns to step SP2.

  As described above, the microcomputer 70 is configured such that the button switch having the number assigned to the user who changed the seat changes the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31 or the rear left seat after the seat change. When pressed by the authentication unit 41, the same music as that output from the speaker before the seat change is controlled to be continuously reproduced from the speaker after the seat change, and the output destination is changed from the speaker before the seat change to the seat. By changing to the speaker after the change, even when a plurality of users change the seat, the same music as that before the seat change can be output from the speaker after the seat change.

(3-2) Output Control Processing Procedure Using Non-Contact IC Card Next, an output control processing procedure using the non-contact IC card, which is actually performed by the microcomputer 70 according to the output control program stored in the ROM, will be described with reference to the flowchart of FIG. Will be described in detail.

  When the power is turned on, the microcomputer 70 of the output control unit 73 in the audio main unit 2 enters from the start step of the routine RT1 and proceeds to step SP11.

  In step SP11, the microcomputer 70 compares the A to D among the receiving units 13, 23, 33, and 43 in the driver seat authenticating unit 11, the passenger seat authenticating unit 21, the rear right seat authenticating unit 31, and the rear left seat authenticating unit 41. If it is confirmed that the user registration has been performed based on the individual non-contact IC card deceived by the above, the process proceeds to the next step SP12.

  In step SP12, the microcomputer 70 operates via operation buttons (not shown) provided in the driver seat authentication unit 11, the passenger seat recognition unit 21, the rear right seat authentication unit 31, and the rear left seat authentication unit 41 of each seat. A plurality of types of music pieces arbitrarily selected by Mr. A to D are reproduced almost simultaneously in parallel by the hard disk drive 61, and the driver seat speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and Different music pieces are provided from the rear left seat speaker 6, and the process proceeds to the next step SP13.

  In step SP13, the microcomputer 70 changes the seats for the receiving sections 13, 23, 33, and 43 of the driver seat authenticating section 11, the passenger seat authenticating section 21, the rear right seat authenticating section 31, and the rear left seat authenticating section 41. It is determined whether or not the information of the non-contact IC card is recognized in response to each of the non-contact IC cards of Mr. A to D being deceived.

  If a negative result is obtained here, this means that the non-contact IC cards of Mr. A to Mr. D are the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, and the rear left seat authentication after the seat change. This means that no one has been deceived by the receiving section 13, 23, 33 or 43 of the section 41, that is, all of Mr. A to Mr. D have not changed their seats. Returning to step SP12, the reproduction of the music is continued as it is.

  On the other hand, if an affirmative result is obtained in step SP13, this means that the non-contact IC cards of Mr. A to Mr. D are the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31 after the seat change. And the receiver 13, 23, 33, or 43 of the rear left seat authentication unit 41, that is, any of A to D is changing seats, The computer 70 proceeds to the next step SP14.

  In step SP14, the microcomputer 70 recognizes the information of the non-contact IC card in step SP13, and as a result, determines whether or not it is completely new data that has not been registered so far.

  If an affirmative result is obtained here, this means that the information on the non-contact IC card is from an unregistered user and it is necessary to register as a new user. Control goes to step SP15.

  In step SP15, the microcomputer 70 performs user registration by storing new data by the unregistered user read from the contactless IC card in a registration data storage area different from the music storage area of the hard disk drive 61, and then performs step SP12. Go back to continue providing music to users who do not change seats.

  On the other hand, if a negative result is obtained in step SP14, this means that the information of the non-contact IC card has already been registered as a user, and it is not necessary to newly register a user. The microcomputer 70 proceeds to the next step SP16.

  In step SP16, the microcomputer 70 has a non-contact IC card deceived by one of A to D who have already registered as a user, and a combination of each seat and the user ID read from the non-contact IC card is used. Determine if there has been a change.

  If a negative result is obtained here, the microcomputer 70 can determine that there has been no change of seats by Mr. A to Mr. D, so at this time the process returns to step SP12 and continues to provide music as before.

  On the other hand, if an affirmative result is obtained in step SP16, this indicates that the seat has been changed by any of A to D. At this time, the microcomputer 70 is notified from the authentication management unit 50. After receiving the input of the external keys S1A to S1D according to the seat change, the process proceeds to the next step SP17.

  In step SP17, the microcomputer 70 recognizes who A-D has changed to which seat by analyzing the external keys S1A-S1D input from the authentication management unit 50, and proceeds to step SP18.

  In step SP18, the microcomputer 70 reads out from the memory 62 the type of music and the elapsed playback time output from the speaker of the original seat before the seat change, and based on this, the speaker of the original seat before the seat change. The output destination is changed by outputting the same music as that output from the speaker after the seat change at a timing after the playback elapsed time, and the process proceeds to step SP15.

  As described above, the microcomputer 70 uses the information on the non-contact IC card of the user who has changed the seat as the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, or the rear left seat authentication after the seat change. When the reception unit 13, 23, 33 or 43 of the unit 41 recognizes, the same music that was output from the speaker before the seat change is reproduced to be continuously output from the speaker after the seat change, and the output destination Can be changed from a speaker before changing seats to a speaker after changing seats, even when the user changes the seat, the user can change the output destination of the music with a simple operation that makes the user trick the non-contact IC card It is made like that.

(3-3) Output Destination Change Processing Procedure from Headphone to Speaker The microcomputer 70 provides music from the driver's seat speaker 3, the passenger's seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6. If the music is provided from the driver's headphone 7, the passenger's headphone 8, the rear right seat headphone 9 and the rear left seat headphone 10 according to the user's selection, a certain condition is satisfied. Sometimes music is provided via the headphones 7 to 10 through the driver seat speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6. An output control processing procedure for forcibly changing the output destination from the headphones to the speaker will be described.

  As shown in FIG. 8, the output control processing procedure for changing the output destination from the headphones to the speaker, which is actually performed by the microcomputer 70 in accordance with the content providing program stored in the ROM, goes from the start step of the routine RT3 to step SP21. Move.

  In step SP21, the microcomputer 70 reproduces different music pieces arbitrarily selected by each of A to D at each seat by the hard disk drive 61 almost simultaneously in parallel, and the driver's headphone 7 and the passenger's headphone 8 are reproduced. Provided from the rear right-seat headphones 9 and the rear left-seat headphones 10 respectively, the process proceeds to the next step SP22.

  In step SP22, the microcomputer 70 determines whether or not the music pieces being played back simultaneously and in parallel by the hard disk drive 61 are the same. If a negative result is obtained, the microcomputer 70 returns to step SP21 to play back the music. On the other hand, if a positive result is obtained, the process proceeds to the next step SP23.

  In step SP23, the microcomputer 70 displays the information on the driver's seat authentication unit 11 because all of Mr. A to Mr. D have been provided with the same music in the driver's seat, front passenger seat, rear right seat and rear left seat. This is notified through the display unit 24, the display unit 24 of the passenger seat recognition unit 21, the display unit 34 of the rear right seat authentication unit 31, and the display unit 44 of the rear left seat authentication unit 41, and the process proceeds to the next step SP24.

  Incidentally, when the power of the audio main unit 2 is turned on, and when Mr. A to Mr. D start to reproduce music by the hard disk drive 61 for the first time, there is a high possibility that the same music will be reproduced. It's easy for everyone to receive the same song.

  In step SP24, if all of A to D are provided with the same music in the driver's seat, the passenger seat, the rear right seat, and the rear left seat, the microcomputer 70 is not the individual headphones 7 to 10 but all. If the same music is output using the driver's seat speaker 3, the passenger's seat speaker 4, the rear right seat speaker 5 and the rear left seat speaker 6, the surround effect in the vehicle interior space is high and a comfortable acoustic space can be provided. Therefore, A to D are inquired about permission to switch from the headphone output by the individual headphones 7 to 10 to the speaker output using all the speakers 3 to 6, and the process proceeds to the next step SP25.

  In step SP25, the microcomputer 70 determines whether or not the consent of switching from the headphone output to the speaker output has been obtained from all of the persons A to D in each seat, and obtains a negative result if the consent has not been obtained from all of the seats. Returning to step SP21, the headphone output is continued, whereas if a positive result is obtained, the process proceeds to the next step SP26.

  In step SP26, the microcomputer 70 uses the same music piece that has been provided individually from the headphone 7 for the driver seat, the headphone 8 for the passenger seat, the headphone 9 for the rear right seat, and the headphone 10 for the rear left seat, for all the driver seats. Switching to speaker output using the speaker 3, the passenger seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6 is carried out, and the process proceeds to the next step SP27 to end the processing.

  At this time, as shown in FIG. 9, the microcomputer 70 has different reproduction elapsed times (indicated by arrows) of the same music, even though all of A to D receive the same music. For this reason, when switching from headphone output to speaker output, the same music is replayed from the beginning.

  When the microcomputer 70 switches from the headphone output to the speaker output as shown in FIG. 10, the headphone output is changed from the headphone output to the speaker output in accordance with the timing when Mr. D, who has not played the same music at the longest playback time. You may make it switch.

  If the microcomputer 70 switches from the headphone output to the speaker output in accordance with the timing of Mr. C, who has the longest playback time, parts that could not be heard by Mr. A, Mr. B, and Mr. C occurred. However, by matching with the timing of Mr. D's playback progress, a part of the music to be listened to for Mr. A to Mr. C is slightly generated, but a part that Mr. D cannot hear is generated. It is possible to provide all the music without missing.

(4) Operation and Effect In the configuration described above, the microcomputer 70 of the audio main body 2 has the Mr. A through the driver's seat speaker 3, the passenger's seat speaker 4, the rear right seat speaker 5, and the rear left seat speaker 6. The type of music and the elapsed playback time individually provided to Mr. -D are stored in the memory 62.

  In the driver seat authentication unit 11, the passenger seat authentication unit 21, the rear right seat authentication unit 31, and the rear left seat authentication unit 41 of the authentication management unit 50, pressing operations on the button switches of the button switch groups 12, 22, 32, and 42 are performed. , A-D can be individually recognized according to the operation of deceiving the non-contact IC card with respect to the receivers 13, 23, 33 and 43, so that the A-D can change the seat. Even if it is done, the positional relationship before and after the seat change can be accurately grasped.

  Thereby, the microcomputer 70 of the audio main unit 2 changes the seat by playing the same music as the music output from the speaker before the seat change when the seats A to D are changed. Since it can be output from a later speaker, the user does not need to perform complicated operations such as selecting music again after changing seats, and only a simple operation such as pressing a button switch or tricking a non-contact IC card. Thus, the same music that was listened to before the seat change can be automatically heard from the speaker after the seat change.

  Further, the microcomputer 70 of the audio main body 2 has all of the same music recorded through the headphone 7 for the driver's seat, the headphone 8 for the passenger seat, the headphone 9 for the rear right seat, and the headphone 9 for the rear right seat. When listening, only when the consent of all of Mrs. A to D is obtained, the speaker for driver's seat 3, speaker for passenger's seat 4, speaker for rear right seat 5 and rear left seat for these headphone outputs By switching to speaker output using all the speakers 6, instead of enjoying music individually by headphone output until all of Mr. A to Mr. D are listening to the same music, switching to speaker output and switching to A Everyone can enjoy the same song.

  Further, the microcomputer 70 of the audio main unit 2 is configured such that when A to D are listening to the same music through headphone output, the speaker 3 for the driver's seat, the speaker 4 for the passenger seat, the speaker 5 for the rear right seat, and the left rear portion. By switching to speaker output using all the seating speakers 6, a so-called surround effect or presence in the vehicle interior space can be expected, and a sound effect far superior to headphone output can be given to the user.
