Patent number: 9315377Abstract: A first sensor section installed in an acceleration sensor employs a first elastic member which is elastically movable according to acceleration in the first and third directions and is stiff against acceleration in second direction so as to restrict elasticity in second direction. Thereby, the first sensor section is provided as a biaxial acceleration sensor which detects the first and third directional acceleration according to a change of electrostatic capacity between a first weight (i.e. the first movable electrode) made movable according to acceleration and the first fixed electrode. A second sensor section installed in the acceleration sensor is structurally identical with the first sensor section and configured to detect acceleration in second and third directions. Thereby, such combination of the first sensor section and the second sensor section constitutes a three-dimensional acceleration sensor.Type: GrantFiled: October 2, 2013Date of Patent: April 19, 2016Assignee: MURATA MANUFACTURING CO., LTD.Inventor: Toshihisa Suzuki

Patent number: 8031890Abstract: 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.Type: GrantFiled: August 15, 2007Date of Patent: October 4, 2011Assignee: Yamaha CorporationInventors: Toshihisa Suzuki, Yuusaku Ebihara, Masayoshi Omura

Patent number: 7579678Abstract: 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.Type: GrantFiled: August 31, 2007Date of Patent: August 25, 2009Assignee: Yamaha CorporationInventors: Toshihisa Suzuki, Junya Suzuki
