摘要

The performance of a miniature loudspeaker used in computer, communication, and consumer electronics products is an integrated function with coupled magnetic, electrical, mechanical, and acoustical fields. Through the finite element method, optimal design parameters to enhance the performance of a miniature loudspeaker are obtained. The sound pressure response of the miniature loudspeaker is simulated by using an equivalent circuit method. Its electrical driver, mechanical motion, and acoustical radiation are analogized by their equivalent elements individually. For the present work, such an analysis is carried out for a miniature loudspeaker manufactured in the cellular phone industry. All speaker parameters in the analysis are experimentally measured. Sound pressure responses are experimentally taken by PULSE Electroacoustics in an anechoic chamber. The equivalent-circuit analysis show fairly good agreement with the experimental results.
