Abstract
A portable communication device includes an audio driver movable within an audio driver housing which forms an expandable chamber. The portable communication device includes at least two portions that are moveably connected to each other allowing the device to be in at least a closed position and an open position. The audio driver can be maintained in a compressed position when the portable communication device is in an open position. Accordingly, the volume of the chamber is independent of the relative position between the portions forming the portable communication device.
