Abstract:
A stereo speaker system including: a speaker unit having a plurality of speakers which output audio; and a filter unit selectively receiving low frequency components of the outputted audio. The filter unit eliminates the received low frequency components to decrease back pressure on the speakers. Thus, the phenomenon of air-loading caused by back-pressure is removed and the low frequency characteristic of stereo speakers is improved by activating the vibration of a vibrating plate.
