摘要： An electroacoustic transducer serving as a speaker or a microphone is reduced in size and weight and is capable of generating sound with relatively high sound pressure. It is constituted of a housing having a cavity having an opening in the exterior, a fixed electrode positioned opposite to the opening of the housing, a diaphragm having an electrode 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 the thickness direction. The fixed electrode is electrically insulated from the electrode of the diaphragm. The diaphragm is distanced from the fixed electrode by means of the elastic deformation portion placed in the balanced state. When the elastic deformation portion is subjected to elastic deformation, the diaphragm vibrates with relatively large amplitude such that it comes in contact with the fixed electrode.

摘要： The present invention provides a condenser microphone, in which, with a simple manufacturing process, vibration characteristics of a diaphragm are improved, and a parasitic capacitance occurring between the diaphragm and a back plate is reduced, thus improving sensitivity. Specifically, the diaphragm having a gear-like shape including a center portion and a plurality of arms and the back plate having a gear-like shape including a center portion and a plurality of arms are positioned opposite to each other above a substrate, wherein the arms of the diaphragm and the arms of the back plate are not positioned opposite to each other. Alternatively, it is possible to independently support the diaphragm and the back plate above the substrate. Furthermore, it is possible to support the back plate above the substrate by means of a plurality of supports inserted into a plurality of holes formed in the center portion of the diaphragm.

摘要： A condenser microphone includes a substrate having an opening in a back cavity, a diaphragm including a center portion and a plurality of arms extended in the radial direction from the center portion, a plate positioned opposite the diaphragm, and a support structure for supporting the periphery of the diaphragm and the periphery of the plate above the substrate while insulating the diaphragm and the plate both having conductive properties from each other. The support structure forms gaps between the substrate, the diaphragm, and the plate. Projections having insulating properties are formed in the center portion and the arms of the diaphragm so as to project towards the substrate and are separated from each other in the circumferential direction of the diaphragm. This prevents the diaphragm from being unexpectedly adhered and fixed to the substrate, thus improving the sensitivity of the condenser microphone.
