The electromechanical of Cymbal transducer has been researched. Under simple supporting condition, the mechanical and electrical characteristics have been analyzed by using Piezoelectric-elastic theory, Kirchhoff ’s thin shell vibration theory, Rayleigh-Ritz’s theory and equivalent circuit method. The approximate 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. The best electromechanical coupling coefficient of cymbal transducer has been gained from the results of numerical analysis. It offers a valid theoretical foundation for optimum design of cymbal transducer. The electromechanical of Cymbal transducer has been researched.
