A flip style cellular telephone includes a main housing, a microphone mounted in the main housing and a flip, pivotably mounted to the main housing by a hinge. The flip is formed with an acoustic pipe on a peripheral edge of the flip. The acoustic pipe extends from the free end to the hinged end of the flip, and includes a plurality of holes for a sound inlet at the free end of the flip. The hinge is hollow, and the acoustic pipe connects with the microphone through the hollow hinge. Sound of the user's voice is carried by the acoustic pipe from the inlet to the microphone. The acoustic pipe advantageously only minimally changes the profile and aesthetics of the telephone.
