    摘要: The present disclosure provides a sound absorbing material. The sound absorbing material includes a sound absorbing material comprising an MFL-structural-type molecular sieve, the MFL-structural-type molecular sieve comprising a skeleton, the skeleton comprising SiO2 and Ga2O3, and the molar ratio of Si/Ga atoms in the skeleton is between 100 and 600. The invention also provides a method for preparing a sound absorbing material and a speaker box using the same. The sound absorbing material provided by the invention, the preparation method thereof and the speaker box using the sound absorbing material can further improve the performance of the speaker box, reduce the failure of the molecular sieve, and improve the performance stability of the lifting speaker box.

    摘要: The present disclosure provides a sound absorbing material. The sound absorbing material comprising a heteroatom zeolite molecular sieve comprising a framework and an extra-framework cation, the framework comprising SiO2 and a metal oxide MxOy comprising a metal element M, wherein the framework has a molar ratio of Si/M between 250 to 500, wherein the M includes Fe, and that the extra-framework cation is at least one of a monovalent copper ion, a monovalent silver ion, a monovalent gold ion, an alkali metal ion or an alkaline earth metal ion. The sound absorbing material provided by the present disclosure, sound absorbing material to have better oxygen adsorption capacity, good waster repellency and stability. When such a sound absorbing material is applied to a speaker box, the speaker box will have better low frequency acoustic performance and better reliability.
