In this paper network methods and Finite-Element methods are combined to optimize the design of a piezoelectric sound generator. The FE-model is used to determine network parameters of the transducer model and finally the behavior of the chosen design variant. For the design optimization the network model is used. One design variant reaches a nominal sound pressure level of 93 dB at a center frequency of 497 Hz and a bandwidth of 242 Hz in the simulation. The computation of the dynamic behavior of a single design variant using the network model was approx. 600k times faster than using the FE-model.
