Cymbal换能器技术的新进展
New Development of Cymbal Transducer Techniques
摘要
Abstract
The double resonance Cymbal transducer and concave Cymbal transducer were designed to improve bandwidth including resonance frequency and compression resistance, increase receiving sensitivity, reduce resonance frequency and decrease volume. The influences of different voltage position and Cymbal cavum height on impedance, bandwidth, transmitting voltage response and receiving sensitivity were analyzed by means of finite element method (FEM) and ANSYS simulation, and the influences of different thickness of piezoelectricity ceramic ring on electromechanical characteristics of concave Cymbal transducer were analyzed by means of finite element method (FEM) and ANSYS simulation. The research result shows that the double resonance Cymbal transducer and concave Cymbal transducer would have a good base of research for engineering application of the Cymbal transducer.关键词
