Abstract

A new way to design demodulation rings in loudspeakers is explored, using the finite elements model.\nThe lossy inductance of the motor coil is characterized for small signals, then this process is extended to the large signals.\nThus a genetic algorithm, based on the differential evolution theory, is developed and coupled with the finite elements software Comsol:\nusing the Pareto optimality concept, the minimisation of impedance variation togheter with the amount of material used is found.
