示回路。In a speaker position indicating circuit of a movable speaker system in which a speaker installed in a vehicle interior is incorporated into a mechanism movable by a motor, a potentiometer converts the current position of the speaker into a voltage value, and a detected voltage of the potentiometer is connected to the speaker. It has a comparator that compares with a reference voltage that indicates the stop position, a voltage dividing resistor network that can generate voltage by switching multiple types of the reference voltage, and multiple input terminals that receive different switch inputs, depending on the level of each input terminal. and an integrated circuit that turns on or off the corresponding output terminal.
The voltage dividing resistor network includes a first resistor having one end connected to a power supply, and a plurality of second resistors each having one end connected to the other end of the resistor, and each of the second resistors 1. A speaker position indicating circuit for a movable speaker system, characterized in that the output terminal of the integrated circuit is made to vary depending on the stop position of the speaker, and the other end is selectively grounded through each output terminal of the integrated circuit.
