Abstract
A portable electronic device, such as a portable radiotelephone (100), with a speaker assembly is described. The portable radiotelephone (100) has a housing, which includes an upper housing (102) and a lower housing (108), configured to carry at least one of a receiver and a transmitter. A speaker (342) has a front side acoustically coupled to a first air space in front of an ear placement region (120) of the upper housing (102). The speaker (342) has a rear side acoustically coupled to a second air space. At least a first passage acoustically couples the first air space to a third air space that is substantially separated from the second air space.
