摘要
探讨了在电动式低音扬声器单元中非线性失真的原因,并且提出了减少偶次谐波的带对称磁路的电动式扬声器单元的某些结构方案。介绍了已进行的降低偶次谐波的方法即应用双低频扬声器单元,该方法还能减小声系统箱体的容积。
The cause of nonlinear distortion in electrodynamic bass loudspeaker unit is discussed, some structural solutions of reducing the even harmonics with symmetrical magnetic eleetrodynamic loudspeaker unit are proposed. The method of re- ducing even harmonics that using dual frequency speaker unit is introduced, and it can reduce the volume of sound system cabinet.
