Loudspeaker simulation is used to inform the designer as to the performance of a design. In recent years the Finite Element Method (FEM) has been used to model the mechanical and acoustical attributes of a loudspeaker with varying success. This paper shows how a model that incorporates the magnetic, electromagnetic, mechanical and acoustical domains performs. These domains will be coupled where necessary and the model will focus on accuracy while trying to remain simple. The results will be directly compared with measured data showing the performance of the model. The results of the simulation show good correlation with the measurements both in the frequency domain and for the electrical impedance.
