Electromagnetic-Mechanical Analysis of a Balanced Armature Receiver by Considering the Nonlinear Parameters as a Function of Displacement and Current

A balanced armature receiver is a multi-physics product in which there is a coupling between the electromagnetic and mechanical domains. To come up with a more accurate analysis method, the nonlinear parameters are considered as functions of current and displacement based on the finite-element method. The current and displacement are solved using the voltage equation through the numerical iteration method. Simulation results are verified through experiments.
