The signal corresponding to the external noise is transmitted to the signal processor 104.

The signal processor 104 receives a signal transmitted from the external noise detector 102 and outputs a control signal for controlling the volume controller 106 connected to the rear stage according to the input signal.

The volume controller 106 adjusts the volume of the auto acoustic device according to the control signal input from the signal processor 104. As such, the volume controlled by the volume controller 106 is output to the outside through the speaker 110.
