发明名称 MICROPHONE
摘要 This invention, directed to a displacement type bone vibration ear microphone possessing an electroacoustic transducer element planted in one of the end faces of a support member and a damper member formed so as to enclose therewith the electroacoustic transducer element, is characterized by disposing a flexible reinforcing member around or near the electroacoustic transducer element, allowing a free end of the electroacoustic transducer element and a outer end of the reinforcing member to be joined or juxtaposed to each other, and enclosing the periphery of the electroacoustic transducer element and the reinforcing member with the damper member thereby providing protection for the electroacoustic transducer element and heightening the efficiency of electroacoustic conversion.
