For example, when the operation element 7 is a button switch or a rocker switch, on / off linked to the operation of the operation element 7. When an off-contact circuit is used for the operation amount detection circuit 20 and the operation element 7 is a rotary switch, a movable contact that moves along with the rotation of the operation element 7 has a fixed contact arranged in a circular shape. A circuit configured to sequentially contact the children is used as the operation amount detection circuit 20.

  The apparatus main body 2 includes a control circuit 30 that controls each part of the in-vehicle acoustic device 1, a power line 31 that transmits power from the ACC power source of the vehicle, and the five connector insertion parts 9, and each connector insertion part. 9, connector insertion ports 9A to 9C are provided. The power supply line 31 is connected to the control circuit 30 and various circuits (not shown), and is connected to the connector insertion ports 9A to 9C of each connector insertion portion 9, and the connector terminal 10 of the operation block piece 6 is a connector. When inserted into the insertion ports 9 </ b> A to 9 </ b> C, the power supply line 31 is electrically connected to the power line 12 of the connector terminal 10 to supply power to the operation block piece 6. A voltage adjusting resistance element or the like is interposed between the connector insertion portion 9 and the power supply line 31.

  Further, the control circuit 30 and the connector insertion ports 9A to 9C are connected by three signal lines of first to third common signal lines 32A to 32C, and each connector insertion port 9A is connected to the first common signal line. Each connector insertion port 9B is connected to the second common signal line 32B, and each connector insertion port 9C is connected to the third common signal line 32C. That is, only the operation amount of the volume adjustment operator 6A is applied to the first common signal line 32A, only the operation amount of the preset selection / adjustment operation element 6B is applied to the second common signal line 32B, and the third common communication line Only the operation amount of the function selection operator 6C is transmitted to the signal line 32C.

Then, when an operation amount is input from the operation block piece 6 (volume adjusting operation element 6A) via the first common signal line 32A, the control circuit 30 determines the magnitude of the audio output signal according to the operation amount. When the operation amount is input from the operation block piece 6 (preset selection / adjustment operation element 6B) via the second common signal line 32B, the preset value is selected and changed according to the operation amount. When an adjustment operation is performed and an operation amount is input from the operation block piece 6 (function selection operator 6C) via the third common signal line 32C, a function selection operation is performed according to the operation amount. Execute.
Thus, the control circuit 30 can appropriately execute the processing corresponding to the operation without determining what operation the operation amount sent out by the operation block piece 6 is for.
