摘要： A piezoelectric electro-acoustic transducer has a substantially decreased resonant frequency without having to modify the size of a piezoelectric diaphragm or the shape of casing members used therein. The piezoelectric electro-acoustic transducer has a piezoelectric diaphragm including a metal plate and a piezoelectric ceramic disc disposed on one surface of the metal plate, wherein the piezoelectric diaphragm is to be supported at its periphery. A plurality of projections are specifically provided for stress transmission suppression at the periphery of the piezoelectric diaphragm in order to suppress or eliminate occurrence of circumferential transmission of a stress at the periphery during activation of the transducer.

摘要： A resonant beam or cantilever is implemented in single crystal silicon or polysilicon. Adjacent the end of the cantilever is an electrode capable of receiving a variable voltage. The cantilever has a natural mechanical resonant frequency when vibrated, and the varying electrostatic field resulting from the variation of applied voltage to the electrode is used to alter the natural restoring force of the cantilever so that a chosen vibration frequency of the cantilever can be achieved. Such vibrating cantilever can be used as the bases for a voltage control oscillator.

摘要： A transducer includes an elongated piezoelectric sensor having only a single integrated mass of piezoelectric material and a pair of relatively longer opposite edges and a pair of relatively narrower opposite edges. The transducer also includes a sensor support that imposes less constraint on one of the pairs of edges than on the other pair.A transducer has two piezoelectric sensors, and a support for supporting the two sensors back-to-back. Each of the sensors being held on opposite edges by a pair of opposite ledges, while two other opposite edges of the sensors are less constrained. The maximum displacement of the two less constrained edges of each sensor are limited by another pair of opposite ledges which are spaced away from the sensor when the sensor is in its normal position.A transducer has two piezoelectric sensors mounted back-to-back on a housing that includes a rib which supports an edge of each sensor. The rib has a hole that opens onto a surface of each of the sensors, and a mass of conductive material is formed in the hole to make electrical connection between the surfaces of the sensors.A transducer includes an elongated chamber having at least one open end to allow fluid to flow into the chamber, and a piezoelectric sensor mounted inside the chamber. The sensor has faces defined by edges, and wicking material is inserted inside the chamber between the sensor and the chamber, for wicking fluid into the chamber.

摘要： For certain applications, such as detecting of glass breakage, it is advantageous to use frequency-selective ultrasonic transducers. In this case, one can dispense with using costly filter configurations to filter out relevant frequency components of the received ultrasonic spectrum. An ultrasonic sandwich transducer, which shows a high sensitivity for certain predetermined frequencies, can be produced by selectively adapting at least one of its geometric dimensions to the frequency selectivity which is required of the transducer. The ultrasonic sandwich transducer preferably has a piezoelectric-ceramic wafer, which is surrounded on at least one of its two wafer surfaces by a layer of low acoustical impedance. The piezoelectric-ceramic wafer is effectively rectangular, resulting in a block-shaped member. One of the dimensions of height, length and width is fixed to correspond to a desired fundamental frequency.
