ABSTRACT:
A speaker system that includes a speaker unit, a cabinet, a plurality of protruding materials, and a gas adsorbing material. The cabinet forms a chamber at a backside of the speaker unit. The plurality of protruding materials are formed inside the chamber and connected to the cabinet. The gas adsorbing material is supported, in a space, by the plurality of protruding materials. Accordingly, it is possible to easily increase a contact area between the gas adsorbing material and the space theresurrounding.
