    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: A vibration transducer includes a substrate, a diaphragm formed using deposited films having conductive property, which has a plurality of arms extended from the center portion in a radial direction, a plate formed using deposited films having conductive property, and a plurality of diaphragm supports formed using deposited films, which join the arms so as to support the diaphragm above the substrate with a prescribed gap therebetween. A plurality of bumps is formed in the arms of the diaphragm so as to prevent the diaphragm from being attached to the substrate or the plate. When the diaphragm vibrates relative to the plate, an electrostatic capacitance therebetween is varied so as to detect variations of pressure applied thereto. In addition, a plurality of diaphragm holes is appropriately aligned in the arms of the diaphragm so as to improve the sensitivity while avoiding the occurrence of adherence.

    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.

    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 semiconductor microphone unit includes a semiconductor microphone chip having a diaphragm covering an inner hole of a support. The support is adhered onto the surface of a support substrate whose thermal expansion coefficient higher than the thermal expansion coefficient of the support via a thermosetting adhesive in such a way that the diaphragm is positioned opposite to the surface of the support substrate. The thermosetting adhesive has a tensile elastic modulus allowing a contraction of the support substrate to be transmitted to the support in a hardened state when the semiconductor microphone chip is cooled together with the support substrate. Thus, it is possible to reduce the tensile stress of the diaphragm, which occurs during the manufacturing of the semiconductor microphone chip, thus preventing the diaphragm from being unexpectedly reduced in strength; hence, it is possible to improve the sensitivity of the semiconductor microphone chip.
