Abstract
Handheld radiotelephones are provided with battery packs that facilitate the transmission of a person's voice to internally mounted microphones. A radiotelephone housing end portion is provided with an aperture that is in acoustic communication with an internally mounted microphone. A passageway extends through a battery pack from a sound inlet in a front portion thereof to a sound outlet in an end portion thereof. The sound outlet is in acoustic communication with the aperture when the battery pack is removably secured to the housing end. Accordingly, the sound inlet is in acoustic communication with the microphone via the passageway.
