摘 要: 研究了测量扬声器振膜杨氏模量和损耗因数(阻尼)的方法。同时针对扬声器纸盆不均厚与弯曲的特点,设计出一种测试精度高,测试结果有重复性的扬声器纸盆成品杨氏模量和损耗因数(阻尼)测量仪器。 The methods measuring Young's modulus and loss factor (damping) of loudspeaker cone is studied in this paper, meanwhile a high-precision instrument is desiqned with the repeatability of test results used for measuring Young's modulus and loss factor (damping) of loudspeaker cone according to non-uniform thickness and bending characteristics of loudspeaker cone.
