摘要
根据PSS公司提供的定芯支片样本,测试了支片顺性的对称性,发现有三分之二的支片顺性有明显的不对称,而且都是支片向外运动的顺性大于向内运动的顺性,这种不对称性将导致扬声器纸盆向外运动振幅大于向内运动振幅,从而产生大量偶次谐波,造成扬声器的声音失真。
According to the spider sample from PSS, the symmetry of compliance is tested. Two - thirds of spiders have strong asymmetries and the upward movement of compliance is greater than the downward movement. This results in loud- speakers outward movement amplitude greater than inward movement amplitude, and generates a large number of even - or- der harmonic distortion which causes the distortion of the sound from loudspeakers.
