摘要：
A speaker device includes a cabinet, a speaker unit, a port, a cartridge, and an adsorbent material. The adsorbent material is disposed in the interior of the cartridge. The cartridge is a container removable from the cabinet. When the adsorbent material is deteriorated, the cartridge is replaced or the adsorbent material is reactivated, thereby making it possible to maintain, over a long period of time, the effect of physical adsorption provided by the adsorbent material.
