In this paper the applicability of an efficient numerical calculation scheme in the computer-aided design of electrodynmic loudspeakers is demonstrated. This modeling scheme is based on a finite element method (FEM) and allows the precise calculation of the electromagnetic, mechanical and acoustic fields including their couplings. Furthermore, nonlinear effects in the mechanical behavior of the spider as well as magnetic nonlinearities due to the nonhomogeneity of the magnetic field are taken into account.
