Abstract

PURPOSE:To simplify a switching operation, by executing the switching operation between a loudspeaker and a headphone loudspeaker by means of an opening operation of a headphone arm. CONSTITUTION:In case of a state that a plug 3' has been inserted into a jack 4', in a state that a headphone 2' has been detached from a head, that is to say, in a closed state of a headphone arm, as for a switch 7, its common contact 7a is connected to the second contact 3'b of the plug 3', that is to say, a switching contact 7b corresponding to a contact connected to a loudspeaker 5', and the loudspeaker 5' is driven. In a state that the headphone 2' has been mounted to a head, that is to say, in an opened state of the headphone arm, the common contact 7a of a changeover switch 7 is switched and connected to a switching contact 7c at the side of a headphone loudspeaker 9 from the switching contact 7b, and the headphone loudspeaker 9 is driven.
