专利汇可以提供Electroacoustic transducer专利检索,专利查询,专利分析的服务。并且An electroacoustic transducer includes an electroacoustic transducer element and inner and outer acoustical reflection plates respectively positioned within an exterior to the transducer element. The electroacoustic transducer element emits an acoustic signal, such as an ultrasonic wave, from both the inner and outer surfaces of the element by expansion and contraction oscillations caused by an electrical signal applied thereto. Similarly, the transducer element can generate an electrical signal by applying an acoustical oscillation thereto. The inner and outer acoustical reflection plates will reflect acoustic oscillations emitted from the inner and outer surfaces in an axial direction in such a manner that a variable range of directivity may be realized and a high acoustic output obtained. The acoustic reflection plates are provided at suitable inclined angles so that the phases of acoustic oscillations emitted in the radial direction from both the inner and outer surfaces of the cylindrically shaped element of the electroacoustic transducer will essentially coincide.,下面是Electroacoustic transducer专利的具体信息内容。

1. An electoacoustical transducer comprising: a cylindrically shaped electroacoustical transducer element, a first conical acoustical reflection plate having a given acoustical impedance mounted within said transducer element for changing the direction of transmission of acoustical osciallations therefrom, and, a second acoustical reflection plate having an acoustical impedance which is the same assaid second acoustical reflection plate mounted in said electroacoustical transducer abutting an exterior surface of said transducer element for changing the direction of taansmission of acoustical oscillations therefrom, said first and second reflection plates having different respective reflecting angles relative to said electroacoustical transducer element and said first and second reflection plates so that the phases of all of the acoustical oscillations reflected from said first and second reflection plates will substantially coincide with each other in the axial direction of the cylindrically shaped electroacoustical transducer element.
