摘要： A system and method for providing effective acoustic impedance matching for a broadband ultrasonic transducer device (UTD) by adding at least one impedance matching plate (IMP) and a shim to the UTD. The IMP is a flat plate with a grid of holes and the shim is disposed between the IMP and the ultrasonic transducer, e.g. piezoelectric transducer, of the UTD.

摘要： A broadband ultrasonic transducer device (UTD) is disclosed that utilizes a plurality of narrow- band piezo electric elements grouped into single-frequency sub-arrays to provide a relatively simple, highly-reliable deterrent unit (DU) capable of emitting ultrasonic energy over a wide coverage area and at a sound pressure level that meets or exceeds other DU approaches. In an embodiment, the broadband UTD includes a housing portion configured to couple to a plurality of piezo sub-array plates. Each piezo sub-array plate includes a plurality of pockets or cavities to receive respective narrow-band (e.g., 1-3kHz) piezo electro transducer elements with characteristics, e.g., geometries and material composition, that cause each to emit ultrasonic energy at a particular resonant frequency. A controller of the UTD implements a control scheme to emit ultrasonic energy in a plurality of output modes including a white noise node and a single-frequency mode for deterrence applications.

摘要翻译：公开了一种宽带超声波换能器装置（UTD），其利用分组为单频子阵列的多个窄带压电元件来提供相对简单的，高度可靠的威慑单元（DU ）能够在广泛的覆盖范围内以及达到或超过其他DU方法的声压级发射超声波能量。在一个实施例中，宽带UTD包括被配置为耦合到多个压电子阵列板的壳体部分。每个压电子阵列板包括多个凹穴或空腔以接收具有例如几何形状和材料组成的特性的各个窄频带（例如1-3kHz）压电电子换能器元件，所述特性使得每个压电电子元件在特定谐振频率。 UTD的控制器实施一种控制方案，以便以包括用于威慑应用的白噪声节点和单频模式的多种输出模式发射超声波能量。
