Abstract:
1. An electroacoustic transducer comprising: a housing having a cavity that has an opening in an exterior; a fixed electrode having a planar shape, which is positioned opposite to the opening and which forms a part of the housing; a diaphragm having an electrode, which is positioned between the opening and the fixed electrode; and an elastic deformation portion for supporting the diaphragm with respect to the housing and for allowing the diaphragm to vibrate in its thickness direction, wherein the fixed electrode is electrically insulated from the electrode of the diaphragm, wherein the diaphragm is distanced from the fixed electrode by means of the elastic deformation portion in a balanced state, and wherein the elastic deformation portion is subjected to elastic deformation so that the diaphragm comes in contact with the fixed electrode.
