Title
(EN) SOUND ABSORBING MATERIAL AND SPEAKER BOX
(FR) MATÉRIAU INSONORISANT ET BOÎTIER DE HAUT-PARLEUR
(ZH) 吸音材料及扬声器箱
Abstract
(EN)
Provided by the present invention is a sound absorbing material, comprising a microporous material and an adsorbate gas absorbed in the microporous material; the microporous material comprises a zeolite molecular sieve, the zeolite molecular sieve comprising a framework and framework outer cations, and the absorption amount of the zeolite molecular sieve for the adsorbate gas is greater than the absorption amount thereof for air. Further provided by the present invention is a speaker box applied to the sound absorbing material. Compared to related technology, the sound absorbing material of the present invention has a good use effect, and the low frequency acoustic properties of the speaker box which employs the described sound absorbing material is better.

La présente invention concerne un matériau insonorisant, comprenant un matériau microporeux et un gaz d'adsorbat absorbé dans le matériau microporeux; le matériau microporeux comprend un tamis moléculaire de zéolite, le tamis moléculaire de zéolite comprenant une structure et des cations externes de structure, et la quantité d'absorption du tamis moléculaire de zéolite pour le gaz d'adsorbat étant supérieure à la quantité d'absorption de celui-ci pour l'air. La présente invention concerne en outre un boîtier de haut-parleur appliqué sur le matériau insonorisant. Par rapport à la technologie associée, le matériau insonorisant de la présente invention présente un bon effet d'utilisation, et les propriétés acoustiques basse fréquence du boîtier de haut-parleur qui utilise le matériau insonorisant décrit sont meilleures.
