摘　　要：扬声器磁路系统的主要作用是为扬声器发声提供驱动力,而驱动力大小直接影响扬声器的电声转换效率。使用COMSOL 5.6仿真软件和FEMM 4.2仿真软件对磁路系统进行电磁仿真,针对不同的扬声器搭配不同的零部件可以获得高性价比的磁路系统。通过仿真软件模拟,对T铁、磁铁、华司及短路环等零部件的尺寸和材质等参数进行调整以优化磁路设计,可以用最少的成本获得最优的声学性能。The main function of loudspeaker magnetic system is to provide driving force for loudspeaker sound.The driving force directly affects the electro-acoustic conversion efficiency of loudspeaker.The magnetic circuit system is simulated by COMSOL 5.6 simulation software and FEMM 4.2 simulation software.High cost performance magnetic circuit system can be obtained for different speakers with different parts.Through simulation software,optimize magnetic circuit system design for different sizes and materials of T-Yoke,magnet,Washer,short circuit ring and other components,so as to obtain the optimal acoustic performance at the lowest cost.
