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 …
