摘要
非织造布作为驻极体传声器极头防尘布 ,不仅起到阻挡灰尘的作用 ,而且具有吸声隔音、调节传声器频率响应曲线的功能。本文结合声学理论和实验 ,分析比较了不同纤维材料和不同结构防尘布对传声器频率响应曲线的影响 。
As the dustproof material for electret condenser microphone, the nonwovens can not only prevent dust into microphone, but also provide the function of sound insulation and adjusting frequency response for microphone. For dustproof material with various fibers and structure, this paper combines the experimentation and acoustical theory to analyze and compare the influence on frequency response for microphone, and provides essential reference for design and manufacture of dustproof nonwoven.
