影响扬声器纸质振膜动态力学性能的因素
The Factors Influencing the Dynamic Mechanical Properties of Paper Diaphragm of the Loudspeaker
摘要
Abstract
The elastic modulu and loss factor of diaphragm are closely related to the acouse characteristic of the loudspeaker.An ideal loud-speaker diaphragm requires higher elastic modulu and proper loss factor.In this work,the influence of paper cone grammage,beating degree of the pulp used for producing paper cone,and lamination structure of paper cone on dynamic mechanical properties of the paper cone was investigated.It was found that with the beating degree and basis weight increasing the elastic modulu of paper cone increased,while the loss factor showed an opposite trend.The lamination structure had an effect on the dynamic properties of the paper cone.Compared with the base paper,dry lamination derived higher density and loss factor and wet lamination derived lower density and higher loss factor.However,there was no significant change in elastic modulu whether dry or wet lamination method was used.关键词
