摘要
采用有限元静态磁路数值分析方法,分析动圈式扬声器单元的驱动力特性,并将分析结果与Klippel R&D系统的测试结果进行比较,验证了该方法的正确性。该方法不仅可替代有经验的电声工程师预估扬声器磁路特性,还可发现和验证产品设计与实际生产制造可能存在的差异。
One numerical method based on finite element（FEM） ,which can calculate force factor in moving - coil loudspeaker through static magnet analysis is presented. In order to verify this numerical method, two models are analyzed and the results are compared with the resuhs from Klippel R＆D. The resah shows that this numerical method is as accurate as estimated by experienced electro - acoustic engineers, and can find the difference between design and manufacture further more.
