喜欢自制音箱的朋友,都知道在自制音箱时,箱内必须填充吸音材料。那么,吸音材料有什么作用,又如何选取和使用呢?现作简要介绍,供自制音箱的朋友参考。箱内吸音材料的作用是增加声阻尼,消除音箱在谐振频率附近的共振现象以及在中频段和高频段产生的驻波,使音箱有均匀的频率特性,并改善非线性失真和瞬态响应。温度均衡材料除具有一般吸声材料的阻尼作用外,还有一个重要作用,就是使音箱腔体工作在等温状 Friends like homemade speakers, all know that in the homemade speakers, the box must be filled with sound-absorbing materials. So, what is the role of sound-absorbing materials, and how to choose and use it? Now make a brief introduction for self-made speakers friends reference. The role of sound-absorbing material box is to increase the acoustic damping, eliminating the resonance of the speaker near the resonant frequency and in the mid-band and high frequency band generated standing, so that speakers have a uniform frequency characteristics and improve nonlinear distortion and transient response. Temperature equalization materials in addition to the damping effect of the general sound-absorbing material, there is an important role is to make the speaker cavity isothermal
