First, the procedure for incoming calls will be described with reference to FIG. That is, when there is an incoming call from the outside (step 301) and the call button is pressed down (step 302), since the two-zone function is ON (step 303), the communication detection unit 30a detects the incoming call, and the voice notification The unit 30b causes the rear seat headphones 6 to output an interrupt sound (see 6a in FIG. 1) (step 304).

  Note that the notification sound may be a chime, a buzzer, a synthesized sound, or the like. This sound is generated by the sound synthesizing circuit 31, mixed with the sound signal of the DVD by the sound mixer 32, and output.

  In addition, the image notification unit 30c displays an interrupt video (see 5a in FIG. 1) on the rear display device 5 (step 305). For example, the visual information is displayed on the display screen as small characters or pictures on a part of the entire screen.

  Furthermore, the output sound from the front speaker 3 is switched from the radio to the hands-free mode (step 306) and transitions to a hands-free call-enabled state (step 307). In this way, the rear passenger who knows that a call has been interrupted is quiet in consideration of the speaker.

[When calling]
Next, the procedure for outgoing calls will be described with reference to FIG. That is, when a call is made by a predetermined operation on the front seat side (step 401), unless it is interrupted (step 402), since the two-zone function is ON (step 403), the communication detector 30a sends a call. Upon detection, the sound notification unit 30b causes the headphone 6 at the rear seat to output an interrupt sound (step 404).

  In addition, the image notification unit 30c displays an interrupt video on the rear display device 5 (step 405). Furthermore, the output sound from the front speaker 3 is switched from the radio to the hands-free mode (step 406) and transitions to a hands-free call-enabled state (step 407). Thus, the passenger in the rear seat who knows that the call has been made is quiet in consideration of the speaker.

[When the call ends]
Further, the procedure when the call is terminated will be described with reference to FIG. That is, when the call end button is pressed down (step 502) from the state during the call (step 501), the call is ended (step 503). The output sound from the front speaker 3 is switched from the hands-free call sound to the original source, for example, radio (step 504).

  Since the two-zone function is ON (step 505), the communication detection unit 30a detects the end of the call, and the voice notification unit 30b outputs a sound indicating that the call has ended to the headphone 6 at the rear seat (step 506). In addition, the image notification unit 30c causes the rear display device 5 to display a video for ending the call (step 507). Thus, the passenger in the rear seat who knows the end of the call knows that no consideration for the speaker is required.

[Effect of the embodiment]
According to the present embodiment as described above, in the case of incoming / outgoing calls on the front side, the rear seat passenger is also notified in the same way as the driver and passenger in the front seat. The presence or absence of a call can be shared as information, and consideration for the speaker can be taken. In particular, the passenger is surely informed because it is forcibly notified to the passenger in the rear seat by voice and video. In addition, by notifying the rear seat to that effect at the end of the call, unnecessary consideration can be prevented and convenience can be provided.

  In addition, each time a call is made, the speaker does not have to call the rear seat passenger verbally, gesturing, touching directly, or performing a selection operation, which is troublesome and does not hinder driving. Realize comfortable calls and safe driving.
