<p>This acoustic speaker (10) is provided with at least two gas adsorbents inside of the speaker cabinet (12). When a speaker unit (13) operates, one of the gas adsorbents, a porous carbon material package (14A), adsorbs or desorbs air by means of a porous carbon material (41) so as to buffer expansion or compression of air in the cabinet (12). The other gas adsorbent, a sheet-form moisture adsorption material (14B), comprises copper ion-exchanged ZSM-5 type zeolite (43) dispersed in a thermoplastic resin composition (44) and is adhered to at least one part of the inner walls of the cabinet (12). By this means, the moisture content in the cabinet (12) can be speedily adsorbed.</p> |
