ホン切替回路。[Claims for Utility Model Registration] A headphone of a multi-amplifier audio device in which a plurality of input acoustic signals with different sound ranges are amplified by a plurality of amplifiers, and the output signals from the plurality of amplifiers drive a plurality of speakers or headphones. a switching circuit that applies a shunt to an acoustic signal input to an amplifier in a predetermined sound range among the plurality of amplifiers, and stops driving a speaker in the predetermined sound range among the plurality of speakers; and the headphone. When the plug is inserted into the jack and the headphone is driven, the plug operates in conjunction with the insertion operation of the plug to disconnect the amplifier from the speaker of the plurality of speakers whose sound range is different from the predetermined sound range. A headphone switching circuit for a multi-amplifier audio device, characterized in that it is equipped with a speaker mute switch that switches the above-mentioned shoot circuit to the operating side.
