动态耳机非线性特性的研究

Study on the Nonlinear Features of Dynamic Earphones

在对动态耳机非线性特性数学分析基础上,提出一种新颖的研究方法并用实验进行了验证。结果表明,这种方法对于耳机这种较弱的非线性系统能很好地定性分析,界定耳机的线性与非线性区域;并且能同时测量耳机的脉冲响应和频率响应,这是常规方法所无法比拟的。

A novel researching method based on the analysis of the nonlinear features of the dynamic earphones is presented. The experimental results show that by using this method,the nonlinear systems in.earphones can be analyzed qualitatively, that the linear and nolinear regions can be determined, and that the pulse and frequency response can be measured simultaneously.
