摘要：PURPOSE:To facilitate an easy handling and at the same time to realize the common use to the transmitter microphones and telephone receivers of each country, by providing an elastic flange which is opposite to the counter part of the transmitter microphone or the telephone receiver, a holding part of the flange and an electro-acoustic transducer. CONSTITUTION:A sound coupler 21 which is set at a telephone receiver base 11 has a basement 22 containing a loudspeaker at the center, and a circular projection 23 is set at the outer circumference of the basement 22. Another circular projection 25 is provided at the inside of the projection 23, and a circular flange 26 made of an elastic material is provided on the projection 25. Then the base 11 is put on the flange 26 based on the projection 23. Thus the flange 26 is pressed down, and the base 11 has a contact with the end parts 26-1 and 26-2 of the flange 26 through the contact surfaces (c) and (d). In such constitution, the sound never leaks outside and furthermore the noise mixed from outside can be avoided.
