| Abstract: | In this paper, a mechanical model of electroacoustic converting system is established, the quantitative relationship between exciting force and input electric power of the system is determined, and the output amplitude response is simulated using the finite element method. Testing experiments indicate that simulating results may meet the needs of the design of electroacoustic converting system. It is a simple and effective method for inspecting the design and manufacture of the system. |
