<p>A speaker system (10) includes a speaker box (12) and a speaker (14) mounted thereon. A bass reflex duct (16) is provided in the speaker box (12) at a position corresponding to an approximate center portion of the speaker (14). In addition, another duct (20) is provided around the speaker (14) in the speaker box. The bass reflex duct (16) is arranged inside of this other duct (20) so that the bass reflex duct (16) and the duct (20) overlap each other. The speaker system is arranged to efficiently direct the back pressure of the speaker (14) to the bass reflex duct (16) and greatly increases the sound pressure in resonance even when a compact speaker box is used. <IMAGE></p> |
