This paper presents a numerical modelling technique for loudspeakers in which a finite element model is coupled with a lumped parameter model. Our approach includes the electric motor system of the loudspeaker in the numerical simulation without increasing the computational cost. This is achieved by considering the motor system as a lumped component, furthermore, parts of the mechanical system are also included in the lumped parameter model.
Lastly, initial results are presented, where we illustrate the effect of including the electric motor system by comparing the proposed model with an acoustic-mechanical finite element model.
