Claim Text:
1. A sealed speaker system, comprising: an enclosure including an opening; a transducer diaphragm mounted within the enclosure, wherein an increase in air pressure within the enclosure results in an outward movement of the diaphragm toward an exterior of the enclosure, and a decrease in air pressure within the enclosure results in an inward movement of the diaphragm toward an interior of the enclosure; and a pressure vent provided in the enclosure, the pressure vent including an exterior portion mounted to the enclosure aligned with the opening, an interior portion disposed within the enclosure aligned with the opening, and a damping material disposed therebetween, wherein the exterior and interior portions are generally rectangular and include a plurality of apertures formed therein for allowing air to pass through, the pressure vent allowing a gradual transfer of air between the enclosure interior and the enclosure exterior to substantially maintain a pressure equilibrium between the enclosure interior and the enclosure exterior.
