Abstract:
The present disclosure provides an acoustic absorption material having a composite zeolite molecular sieve and a speaker using the acoustic absorption material, where the composite zeolite molecular sieve includes a first zeolite molecular sieve having a first micropore diameter and a second zeolite molecular sieve having a second micropore diameter, and the first micropore diameter is greater than the second micropore diameter, and the first zeolite molecular sieve is used as an adsorbent, and the second zeolite molecular sieve is used as a low-frequency enhancement material. In the present disclosure, a zeolite molecular sieve having a larger diameter is added as an adsorbent to a zeolite molecular sieve, to effectively absorb various volatile organic compounds (VOCs) in an application environment, thereby avoiding performance degradation or failure of the zeolite molecular sieve used as a low-frequency enhancement material.
