Total Harmonic Distortion of a Piezoelectric MEMS Loudspeaker in an IEC 60318-4 Coupler Estimation Using Static Measurements and a Nonlinear State Space Model

We propose a method to evaluate the Total Harmonic Distortion generated by a cantilever-based PZT loudspeaker inside an IEC 60318-4 coupler.The model is validated using experimental data of a commercial loudspeaker.Using the time domain equations of the equivalent electrical circuit of the loudspeaker inside the coupler and a state space formulatio
