摘　　要：用Ansys有限元软件对扬声器磁路进行计算机仿真计算。内磁式和外磁式两种扬声器磁路计算表明,要达到相同的气隙磁场,内磁式磁路可以减小永磁体的用量和漏磁场。因此,该仿真计算为扬声器磁路的计算和设计提供了理论依据,并且为扬声器磁路的进一步优化设计提供了一种计算方法。Ansys finite element software was used for the calculation of speaker magnetic circuit. The calculation for both inner- and outer-magnet type circuit indicated that for the same gap magnetic-field, less volume of magnet is needed and leak field is reduced for the inner-magnet circuit. So the simulation can provide not only the theoretical basis for the peaker magnetic-circuit＇s calculation and design, but also a calculation method for further optimum design of speaker magnetic circuit.
