Abstract
Official abstract text for this publication.
An acoustic speaker device ( 10 ) according to the present invention comprises at least two types of gas adsorption materials in a cabinet ( 12 ) thereof. A porous carbon material package member ( 14 A), which is one of the gas adsorption materials, can adsorb or eliminate air in the cabinet ( 12 ) by a porous carbon material ( 41 ) during the operation of a speaker unit ( 13 ) so as to buffer compression or expansion of air in the cabinet ( 12 ). A sheet-like moisture adsorbing material ( 14 B), which is the other of the gas adsorbing materials, is formed by dispersing copper ion-exchanged ZSM-5 zeolite ( 43 ) in a thermoplastic resin composition ( 44 ), and is stuck on at least a section of an inner wall of the cabinet ( 12 ). This configuration allows moisture in the cabinet ( 12 ) to be rapidly adsorbed.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acoustic speaker device, comprising: a cabinet; a speaker unit mounted on the cabinet; and a gas adsorption material provided inside of the cabinet and being capable of adsorbing moisture and a gas component in the cabinet; wherein the gas adsorption material is composed of at least a porous carbon material and a sheet-like moisture adsorbing material, wherein the sheet-like moisture adsorbing material is formed by dispersing c…
