发明名称 Speaker system
摘要 A speaker system includes a cabinet, at least one speaker unit fixed to the cabinet, and a gas adsorbent which is situated inside the cabinet and which is made from a porous material. The speaker unit is configured with moisture-proof component parts. In the speaker system, a tubular structure which has a tubular hollow allows ventilation between an inside and an outside of the cabinet. A resonant frequency which is determined by an acoustic impedance of the tubular structure and an acoustic impedance of the cabinet is lower than a minimum resonant frequency of an acoustic impedance of the speaker system.
