Abstract

PURPOSE:To obtain a sound coupler usable for general purposes, by varying the interval of two receptacles which are respectively coupled with a receiver and a transmitter of a handset. CONSTITUTION:A long groove 10 is provided on the upper surface of a main body chassis of a sound coupler, and a slide plate 11 is inserted to the long groove 10 freely slidably. On the upper surface of the slide plate 11, a receptacle 12 made of elastic material such as rubber to which a transmitter of a hand set is coupled, and fixed. A speaker 13 is built in the center of the receptacle 12, and the speaker 13 is connected internally with flexible wires such as flexible cables. On a slope 9A of the chassis 9, a receptacle 14 made of elastic material to which the receiver is coupled, and fixed, and microphone 15 is built in.
