The magnetic response of the PZT disc of 40 mm diameter has also been studied. For studying the stationary and dynamic performances of the PZT disc, simulation of the disc for a set range of frequency using COMSOL Multiphysics is done. A circular PZT disc is modelled and analysed practically for variation in thicknesses and diameters of its plate on COMSOL Multiphysics. The fundamental design requirements like oscillations in the audible frequency range and maximum surface displacement have been considered. Displacements of diaphragm under different magnetic field strengths have been analysed. A novel simulation has been executed to find the behaviour of the piezo structure under the influence of magnetic field. In the following paper, an analysis for the design of efficient piezoelectric-based speaker is carried out. When acoustic voltage signals are put across the ceramic part of the piezoelectric speakers, it leads to the oscillation of the material. When voltage is applied to the speaker, it will create waves of sound. Piezoelectric speakers work on the inverse piezoelectric effect to produce sound.
