Abstract
An acoustic speaker device () according to the present invention comprises at least two types of gas adsorption materials in a cabinet () thereof. A porous carbon material package member (A), which is one of the gas adsorption materials, can adsorb or eliminate air in the cabinet () by a porous carbon material () during the operation of a speaker unit () so as to buffer compression or expansion of air in the cabinet (). A sheet-like moisture adsorbing material (B), which is the other of the gas adsorbing materials, is formed by dispersing copper ion-exchanged ZSM-5 zeolite () in a thermoplastic resin composition (), and is stuck on at least a section of an inner wall of the cabinet (). This configuration allows moisture in the cabinet () to be rapidly adsorbed.
