基于ANSYS Workbench的微型扬声器磁路优化分析

摘要

For the problem of the analysis of the square loudspeaker is less . This paper using Solid Works to establish the magnetic circuit part of the square model micro loudspeaker, the magnetic circuit are electromagnetic analysis by ANSYS Workbench, get the distribution of magnetic flux lines and the voice coil BL graphs (the diagram between magnetic flux density and width of voice coil winding) , and analysis magnetic flux density changes in different positions of the square coil, provide a basis for further optimization design of the speaker. This paper provides an alternative analysis method for the magnetic circuit of the speaker.%针对方型扬声器的分析目前较少的问题。本文利用 Solid Works 对方型微型扬声器磁路部分进行建模，在ANSYS Workbench中对磁路进行电磁分析仿真，得到磁力线分布以及音圈的BL曲线（磁通密度与音圈绕线宽度关系图），并分析方型音圈上不同位置的磁通密度变化，为扬声器的进一步优化设计提供依据。本文为扬声器的磁路分析提供了一种可选择的方法。
