摘要： A condenser microphone includes a substrate having a cavity, first and second spacers defining an opening, a diaphragm having a rectangular shape positioned inside of the opening, and a plate having a rectangular shape positioned just above the diaphragm. Plate joint portions integrally interconnected with two sides of the plate are directly attached onto the second spacer. Supports, which are attached onto the second spacer across the opening and project inwardly of the opening, are connected to the prescribed portions of the diaphragm via third spacers relatively to the other two sides of the plate. The center portion of the diaphragm can be designed in a multilayered structure, and the peripheral portion can be bent outwardly. In addition, both ends of the diaphragm are fixed in position, while free ends of the diaphragm vibrate due to sound waves.

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： A vibration transducer (e.g. a condenser microphone) having a high sensitivity is constituted of a housing composed of an airtight material having a through-hole, a vibration conversion die (e.g. a microphone die) which is attached to the interior surface of the housing at the prescribed position embracing the through-hole in plan view, and a barrier diaphragm composed of an airtight material whose external periphery is attached to the exterior surface of the housing in an airtight manner oppositely to the prescribed position. The barrier diaphragm has a vibration area which is larger than the sectional area of the through-hole. A space allowing the barrier diaphragm to vibrate is formed between the barrier diaphragm and the exterior surface of the housing, wherein the distance between the barrier diaphragm and the exterior surface of the housing can be gradually reduced from the vibration axis to the external periphery.

摘要： An electrostatic capacity sensor includes a sensor die including a bias electrode and a signal electrode, which are positioned opposite to each other with a very small distance therebetween, and a shield member including a potential stabilizing conductive film whose external shape encompasses the vertically projected area of the signal electrode. The sensor die joins the joint surface of the shield member. The signal electrode is positioned between the bias electrode and the potential stabilizing conductive film. A noise shield adapted to the signal electrode is formed using the bias electrode and the potential stabilizing conductive film; hence, it is possible to improve the noise resistance of the signal electrode and to increase the S/N ratio in sensitivity.

摘要： A condenser microphone includes a support, a plate having a fixed electrode bridged across the supports, a diaphragm, which has a moving electrode at a center portion thereof and which vibrates due to sound waves applied thereto, and a spacer, in which a first end is fixed to the plate, and a second end is fixed to the near-end portion of the diaphragm so as to surround the center portion of the diaphragm, wherein an air gap is formed between the plate and the diaphragm. This reduces the tensile stress of the diaphragm so as to increase the amplitude of vibration of the diaphragm. Hence, it is possible to increase the sensitivity of the condenser microphone. A structure constituted of the plate, the diaphragm, and the spacer is bridged across the support by means of the bridges, which absorb the residual stress of the diaphragm due to the deformation thereof.
