减少音箱振动影响的技术途径初探

对音箱的无益振动和现有的处理技术作了分析,并对"单元悬浮技术"和在音箱里采用"穿孔板吸声结构"的新技术途径进行初步探讨。"单元悬浮技术"可以达到目前最好的振动隔离,而"穿孔板吸声结构"在音箱里的应用,不但解决了音箱内的低频声波未能得到有效吸收的问题,而且还有降低箱体的驻波、提高隔声量等附加作用。

Discussion for the New Techniques to Decrease Vibrations of Loudspeaker Boxes

The unnecessary vibrations and the processing technique at present are analyzed, and the new techniques inclu- ding ＂the driver suspension technique＂ and ＂the sound absorption structure of perforated plates＂ are primarily discussed. In this paper, the driver suspension technique is described as the best one to isolate vibration from the driver. And applications of the sound absorption structure of perforated plates in loudspeaker boxes, not only absorb low sound frequency components with effect, but also decrease the intensity of standing wave and increase the sound insulation factor.
