Abstract

PURPOSE:To improve greatly the fidelity of the whole transmission system by magnetically coupling a transmitting-receiving magnetic coil and the voice coil of a receiver mutually opposing. CONSTITUTION:Telephone set 6 is provided with transmitter 6a and receiver 6b, small shock-proof projections 2a and 2b are formed on the external surface of coupler body 2, and main body 2 is fitted in housing 1. Then, telephone set 6 is inserted into a clearance between housing 1 and main body 2, transmitter 6a is blocked by main body 2, and trasmitting-receiving coil 3 couples magnetically with the voice coil of receiver 6b opposing to it. Consequently, a current flowing through the voice coil of receiver 6b is picked up by coil 3 and the fidelity of the whole transmission system can greatly be improved.
