Abstract: We present a novel time-dependent simulation method to calculate the response of a loudspeaker motor. The model allows for the simulation of complex signals and predicts the large-signal behavior including motor nonlinearities using only the motor geometry and material parameters without the need to measure physical samples. The transient large-signal simulation is made possible by the implementation of a moving-mesh algorithm for the displacement of the voice coil. Two motor geometries are simulated with different input signals, ranging from simple sine to complex random signals. The method provides previously unavailable insight into effects of flux modulation. The results are validated against a lumped parameter model and experimental measurements. The presented method can be used to compare different motor geometries before the prototyping stage, which is a useful tool for loudspeaker transducer engineers.
