手机扬声器面盖开孔的电声性能初步探讨

Electroacoustic Effect by the Cover Apertures for Speaker Used in Mobile Phone

手机扬声器的面盖不仅起保护扬声器的作用,而且会对电声性能产生影响。研究了面盖开孔率、均匀与对称排列方式、非均匀和非对称排列方式与手机扬声器电声性能的关系。实验测试表明,面盖开孔对手机扬声器电声性能有明显影响。并给出结合扬声器设计面盖的实例。

The mobile phone speaker cover can not only protect the speaker, but also have an influence on the electroacoustic characteristics. Perforated ratio, even and symmetry perforation, as ,sell as uneven and asymmetry perforation are analyzed by the electroacoustic measurement. The results indicate that apertures on the cover can affect electroacoustic performance. An example of designing cover is given.
