Abstract

This paper presents a simulation study of diaphragm based piezoelectric acoustic sensor. It describes the results of modeling, dynamic behavior study of circular and square structured diaphragm and comparative study of diaphragm structure on the basis of SPL(sound pressure level) and Displacement using Comsol Multiphysics.
