The vibroacoustic behavior of loudspeakers has a closed form mathematical model only for limited low frequency range and for simple geometry. With recently powerful computers and commercial numerical software, it is possible to model accuratelyreal loudspeakers in the whole frequency range. This paper demonstrates the use of the commercial softwares packages in the analysis of the vibroacoustics characteristics of loudspeakers. The vibration response is calculated by the finite element method (FEM), with the applied force obtainedpreviously by use of the lumped-parameter model. The vibration result is then used to calculate numerically the acoustic radiation response by the boundary element method (BEM). The modal analysis of a three dimensional cone was presented in [1], while an experimental modal analysis was already reported in [2]. In this paper, the theoretical results of modal analysis by FEM of a three dimensional model for the loudspeaker cone are compared with results of an experimental modal analysis and the predictedsound pressure level is compared with frequency response measurements.
