Design method of cymbal transducer structure parameters based on finite element analysis

Structure parameters of cymbal transducer play an impotent role in its performance. It is complicated to analysis the cymbal transducer with traditional methods, such as equivalent circuit method. The results of traditional methods are difficult to be used for structure optimization. Finite element method (FEM) takes structure parameters into account, and result data are more accurate and direct. Admittance, transmitting voltage response (TVR) and free field voltage sensitivity (FFVS) of cymbal transducers with different structure parameters were researched with FEM. Conclusions were drew out from results of finite element analysis (FEA) about how structure parameters affect transducer´s performance. A sample transducer was developed and tested in an anechoic tank. Data from measurement agreed well with data calculated from FEA software ANSYS. Methods discussed in this article are useful to optimize cymbal transducers and develop cymbal transducer array.
