Mechanical and electrical characteristics of cymbal transducer

The electromechanical of Cymbal transducer has been researched. Under simple supporting situation, the mechanical and electrical characteristics have been analyzed with Piezoelectric-elastic theory, Kirchhoff's thin shell vibration theory, Rayleigh-Ritz's theory and equivalent circuit method. The approximately solution and series resonance frequency equation have been given. Under no load, equivalent circuit, correlation parameters of Cymbal transducer and the relations between the ratio of cavity depth to radius of Cymbal transducer with resonance frequency, electromechanical coupling coefficient of Cymbal transducer have been researched. According to results of numerical analysis, the best electromechanical coupling coefficient of Cymbal transducer has been gained. It offers a valid theoretical foundation for optimum design of Cymbal transducer.
