FEMM在扬声器磁路分析中的应用

Applications with FEMM in bass speaker magnetic-circuit analysis

本文介绍了适用于低音扬声器的几种不同充磁方向的应用磁路,并引入有限元法,利用磁场有限元分析软件FEMM对选择的磁路进行分析,得到了较好的效果,指出了一种新的磁路分析途径。

This paper presents several kinds of magnetic- circuits for bass speaker, which are magnetized in different orientations. It carries on the analysis using magneticfield finite element analysis software FEMM to the magnetic-circuit choice, and obtained a better effect. One new magnetic-circuit analysis way has been pointed out.
