Abstract: 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.

Abstract: A condenser microphone includes a microphone chip and an LSI chip, which are stored in a microphone package having a sound hole. External sound enters the sound hole so as to propagate through the internal space of the microphone package, so that it is received by the microphone chip. The microphone package is designed to set the Helmholtz resonance frequency within the audio frequency range. The output signal of the microphone chip is supplied to an impedance converter included in the LSI chip. The output signal of the impedance converter is attenuated by an attenuation device with respect to the prescribed frequency band including the Helmholtz resonance frequency, which decreases when the condenser microphone is installed in the housing of an electronic device. Thus, it is possible to achieve the flat frequency characteristics in the output signal of the condenser microphone, which is thus improved in the S/N ratio.

Abstract: An electroacoustic transducer includes a condenser microphone, which includes a package having a cavity and a through-hole, a plate whose thickness is thinner than the length of the through-hole and which has a sound hole overlapping with the through-hole in plan view, and an electroacoustic transducer die, which is stored in the cavity of the package. The electroacoustic transducer die includes a fixed electrode and a diaphragm electrode, which are positioned opposite to each other and which are supported by and enclosed inside of a support. The sound hole of the plate is reduced in dimensions realizing a small sectional area and a small depth, thus realizing a high resonance frequency higher than the audio frequency range.

Abstract: A condenser microphone 14 and an accelerometer 16 are placed on a device substrate 12 with arranging same sides in a same direction. Both condenser microphone 14 and accelerometer 16 are formed of condenser microphones. Sizes of the condenser microphone 14 and accelerometer 16 are same other than diameters of back cavities 20 and 120. A step 40 that decreases an inner diameter of the back cavity 20 is formed inside the back cavity 20 to function as an audio resistance, whereas the back cavity 120 of the accelerometer 16 has no step (audio resistance). A microphone output is obtained by subtracting a terminal voltage of the condenser microphone 14 by a terminal voltage of the accelerometer 16.

Abstract: 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.
