For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and selection via COMSOL Multiphysics® software. The validation is made by comparing with both the corresponding combined FE-LE model and the full FE model. Numerical results prove the developed model is not only as effective as the combined FE-LE model, but also much more efficient.
