Abstract
A speaker system includes an enclosure defining a resonance chamber, a loudspeaker received in the resonance chamber, and a sound wave reflecting member. The enclosure includes a front panel and a base. The loudspeaker is exposed at the front panel. The base includes a back panel facing the front panel, an inner tube, and an outer tube. The back panel defines a back bass port. The inner tube and the outer tube extend from the back panel and are received in the resonance chamber. The inner tube surrounds the back bass port. The outer tube surrounds the inner tube. The sound wave reflecting member is coupled with the outer tube and the inner tube. The sound wave reflecting member, the outer tube, and the inner tube cooperatively form a resonator. The resonator communicates with the resonance chamber and the back bass port.
