矩形板式压电骨传导听觉装置声发生元件关键参数仿真研究

Resonance frequency and displacement are two important parameters in measuring the loudness at the low frequency region of piezoelectric bone conduction hearing device. Using Ansys to build the finite element model, analyzing the influence of different sizes of piezoelectric oscillator and support column on resonance frequency and displacement by simulation analysis, thus to provide the theoretical basis for searching appropriate vocal element for hearing device.
