A numerical model for optimization of loudspeakers mounted in infinite baffles is presented in this paper. The optimization is carried out by using objective functions based on basic response characteristics for loudspeakers such as the on axis frequency response. In-order to create a realistic model of the speaker we include the
excitation of the speaker from the motor system. The interaction between acoustic medium and structure is modelled with the finite element method. As most loudspeaker drivers are nearly symmetric, the presented model is a 2D axisymmetric finite element model. The exterior domain is modelled with perfectly matched
layers, which ensure free-field radiation conditions. Optimized designs for a selection of objective functions are presented and discussed.
