本文对电动式纸盆扬声器所产生的阻尼作了较为系统的分析,同时介绍其测量方法。且文中以直径55毫米扬声器为例进行实际测定,从测量结果表明:阻尼的分析与测定,不仅可以控制扬声器的频率响应特性,而且亦为扬声器低频段的设计工作提供参考数据。 This paper makes a systematic analysis of the damping caused by the electric cone speaker, and introduces the measurement method. In the paper, 55mm diameter speaker is taken as an example to make an actual measurement. The measurement results show that the analysis and determination of damping can not only control the frequency response characteristics of the speaker, but also provide reference data for the design work of the speaker in the low frequency range.
