ANTISTATIC SOUND-ABSORBING MATERIAL AND PREPARATION METHOD THEREFOR, AND LOUDSPEAKER AND ELECTRONIC DEVICE
An antistatic sound-absorbing material and a preparation method therefor, and a loudspeaker and an electronic device. The antistatic sound-absorbing material comprises molecular sieve particles, an adhesive and an antistatic additive, wherein taking the total weight of the molecular sieve particles as 100%, the weight of the antistatic additive is 0.5-10% of the total weight of the molecular sieve particles. By means of providing the antistatic sound-absorbing material provided in the present invention on a rear cavity of a loudspeaker of an electronic device, the problems of agglomeration and interface attachment caused by an accumulation of static electricity generated by friction and collision between materials can be solved, such that loss can be reduced, and the filling quantity is increased, thereby guaranteeing stability during long-term use.
