Electroacoustic transducer

Abstract

The object of the present invention is to provide an electroacoustic transducer characterized in that the desirable tension of a diaphragm is not changed, the interval between the diaphragm and the electrode portion can accurately be kept, the amplitude of the diaphragm in response to sound waves can be increased, and the influence of an external force can be reduced. According to an aspect of the present invention, there is provided an electroacoustic transducer comprising a carrier portion, a diaphragm supported by the carrier portion, an electrode portion opposed to the diaphragm at a predetermined interval, and a housing for accommodating the diaphragm and the electrode portion, wherein the carrier portion has a saucer-like shape, at the bottom surface of which a plurality of posts are provided, and wherein the surface of the periphery of the carrier portion and the end surfaces of the posts are allowed to be in the same plane, the diaphragm is bonded to the surface of the periphery of the carrier portion and the end surfaces of the posts, and the electrode portion is fixed to the end surfaces of the posts which are covered by the diaphragm with spacers interposed therebetween.
