摘要： An ultrasonic probe for coupling acoustic signals between the probe and a medium is provided. The ultrasonic probe has a piezoelectric element having a plurality of piezoelectric layers each having a different acoustic impedance. The piezoelectric layers are stacked in progressive order of acoustic impedance such that the layer with the acoustic impedance nearest to that of the medium is proximate the medium. At least one of said piezoelectric layers is made of piezoelectric composite material. The ultrasonic probe further has an electrode means for electrically coupling the piezoelectric layers to a voltage source for applying an oscillation voltage potential to each piezoelectric layer. The probe further has a control means for controlling the polarization of at least one of the piezoelectric layers.

摘要： An ultrasonic probe for providing efficient and controlled acoustic coupling to a desired medium under examination by the probe. The ultrasonic probe of the present invention employs one or more ultrasonic transducers substantially surrounded by a fluid. The ultrasonic transducer is acoustically coupled to the fluid for transmitting the beam of acoustic signals therethrough. A housing that is acoustically coupled with the fluid substantially encloses the fluid and the transducer. The housing comprises a layer portion of a material contiguous with a bulk remainder portion of the material. Additionally, an impedance matching means is integral with the housing for controlling an acoustic impedance of the layer portion of the housing.

摘要： In the speaker system, an acoustic pipe for conducting a sound wave is arranged in front of a speaker for reproducing a middle and low frequency sound. The acoustic pipe has a rectangular open end portion. A speaker for reproducing a high frequency sound is disposed within the acoustic pipe coaxially with and in front of the speaker for reproducing the middle and low frequency. With this construction, attenuation of middle and high frequency components of sound signals which are produced from the middle and low frequency sound reproducing speaker is suppressed. Moreover, it is possible to conduct the high and middle frequency components and a high frequency component, which is reproduced by the high frequency sound reproducing speaker, as naturally composed sound signals to the open end portion of the acoustic pipe. The speaker system thus exhibits excellent characteristics in sound image localization and articulation of sound, thereby providing a high tone quality to the TV. The TV may be miniaturized with the speaker system.

摘要： An acoustic pressure pulse generator has an electrodynamic pressure pulse source formed by a membrane and a coil, so that when the membrane is electrodynamically rapidly repelled from the coil, an acoustic pressure pulse is generated in an acoustic propagation medium adjacent the membrane. A wall is disposed in the pulse generator spaced from the membrane in the direction of pressure pulse propagation, the wall preferably formed as an acoustic lens. The wall defines a space between the wall and the membrane, which is filled with acoustic propagation medium, and which is maintained liquid-tight from a second space situated at the other side of the wall, also containing an acoustic propagation medium. The acoustic propagation medium contained in the first space is maintained at a static pressure which is necessary for returning the membrane to its initial position after being repelled by the coil. The propagation medium contained in the first space can be maintained pressurized by flowing through a circulatory system which is also used for cooling that acoustic propagation medium.
