| Abstract: | Taking a kind diaphragm of micro loudspeaker as an example,a finite element analysis based an ANSYS Workbench is studied and explained.Stress regulation of diaphragm is obtained by using static analysis; and each rank of modal shape and resonance frequency are all achieved by applying modal analysis; and the relations of different material and the equivalent compliance.And the results of this study,a theoretical reference to design and performance improve of the micro loudspeaker diaphragm is provided. |
