Abstract
A speaker enclosure includes a gas cavity and an air cavity separated by a flexible membrane. A diaphragm is located roughly in an opening of the enclosure surrounding the gas cavity and attached to the enclosure by an outer suspension member. The enclosure, the flexible membrane, the diaphragm, and the outer suspension member are gas and air impermeable. The enclosure surrounding the air cavity has a vent hole to allow air to travel into and out of the air cavity for barometric pressure equalization of the gas cavity. Other embodiments are also described and claimed.
