Abstract
Provided is a sound-absorbing material, including an adsorbent material and a thermal conductive material. The thermal conductive material is uniformly dispersed in the sound-absorbing material. The thermal conductive material includes a carbon fiber material, and a weight ratio of the carbon fiber material in the sound-absorbing material is within a range of 0.05% to 10%. Further provided are a preparation method of the sound-absorbing material and a speaker using the sound-absorbing material. The sound-absorbing material has higher thermal conductivity and can be added to a rear cavity of the speaker to effectively conduct heat generated when the speaker is working, thereby improving the heat dissipation performance of the speaker.
