折环劲度系数与磁场力因子的匹配

Matching of Edge Stiffness Factor and Magnetic Force Factor

失真是扬声器的一个重要性能指标,引起扬声器失真的主要因素是折环与磁路系统的非线性。将折环和磁路系统当作一个整体来研究。介绍了折环的劲度系数如何与磁场力因子配合,以达到降低失真的效果。

Distortion is an important performance index of loudspeaker. And the principle elements to cause distortion are the nonlinearity of edge and magnetic circuit system. The edge and magnetic circuit system is combined as a whole to research. The method to match the edge stiffness factor for the magnetic force factor is introduced to reduce distortion.
