MICROPHONE

摘要

PROBLEM TO BE SOLVED: To make a novel microphone available while leaving a conventional casing section unchanged. SOLUTION: A cylindrical tube 32 having an angular hole is prepared to cover a parallelopiped microphone 31. Thus, the external form of the microphone practically becomes columnar and can be attached in the conventional microphone housing part of equipment as it is. The tube is made of elastic materials and when the tube covers the microphone, it is held by elasticity. The outside dimension of the same microphone can be changed into any dimension and can be adaptive to the dimension series of the conventional product.
