Abstract

PURPOSE:To prevent sound-electric signal conversion from being spoiled by inserting a handset into a receptacle by an operator and then detecting sound leakage, to couple the receptacle with the handset always in the optimum state. CONSTITUTION:In the top surface of a main body 9, receptacle parts 10 and 13 made of elastic materials such as rubber are fixed to fit and couple the transmission and reception parts of a handset therein respectively, and a speaker 11 and a microphone 14 are embedded in the centers of them respectively. Further, microphone switches 12a-12c, and 15a-15c for detecting sound leakage are provided around the speaker 11 and microphone 14 in the same bodies with the receptacle parts 10 and 13 respectively. When the handset which is not shown in the figure is inserted into the receptacle parts 10 and 13 and the microphone switches are all in operation, it is recognized that the coupling between the coupler and handset is excellent, thereby turning on a lamp 16.
