The use of finite element analysis is quite common in modern design techniques. Modeling allows to save time and efforts, especially when complex phenomena have to be considered. A compression driver is an example of a product with a problematic design, because the great number of variables and the different physics that are involved in the sound generation process makes the direct solution of mathematical models not trivial. In this paper an algorithm that optimizes the design parameters of the driver through an evolution strategies based procedure, taking advantage of the accuracy of the results from finite elements simulation, is presented. The method has been tested by optimizing a real compression driver and the results are reported.
