Abstract: The present application provides a sound adsorbing material, including a microporous material and an adsorbate gas adsorbed in the microporous material. The microporous material includes a zeolite molecular sieve, and the zeolite molecular sieve has a framework and extra-framework cations. An adsorption capacity of the adsorbolite molecular sieve to the adsorbate gas is greater than an adsorption capacity of the adsorbolite molecular sieve to air. The present disclosure further provides a speaker box adopting the sound adsorbing material. Compared with the related art, the sound adsorbing material provided by the present disclosure has good application effects, and the speaker box using the sound adsorbing material has a better low frequency acoustic performance.

Abstract: The present disclosure relates to a molecular sieve, preparation thereof and acoustic absorption material and speaker containing the same. The molecular sieve having an MFI-structure, comprising a framework and an off-framework cation, wherein the framework comprises SiO2 and a metal oxide MxOy with M comprising boron, gallium or aluminium; the off-framework cation is at least one of hydrogen ion, alkali metal ion and alkaline earth metal ion. The molecular herein can effectively prevent the failure of the molecular sieve and improve the performance stability of the speaker.

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.
