ABSTRACT:
A vibration-detecting-type microphone for detecting voice vibrations by being contacted to the buccal region or the mastoid of the temporal region of a user. This microphone has a belt-like diaphragm whose both ends are fixed to a casing with one end open, a piezoelectric element installed on the rear central part of this diaphragm, and a vibration pickup situated on the external surface of this diaphragm and designed to be contacted with the human body. The rear surface of the vibration pickup has at least one pair of sensing elements, and these sensing elements are located in such a way that they will not oppose the piezoelectric element through the diaphragm. This arrangement makes it possible to select and set the resonance frequency of the diaphragm and microphone, as desired. In addition, since the sensing elements of the vibration pickup are supported at two points or more by the diaphragm, the concentration of stress into the diaphragm as well as the damaging of the piezoelectric element can be prevented.
