Abstract
A telephone set (10) comprises a first housing (12), a second housing (14), a rotate (54) or a slide (34) mechanism, a microphone (16), an earpiece (18) and a keypad (20). The rotate (54) or the slide (34) mechanism couples the first housing (12) to the second housing (14) and permits the first housing (12) to be moveable relative to the second housing (14) between a first, closed or contracted, position (22) and a second, open or expanded, position (24). The microphone (16) is carried by the first housing (12) and is adapted to convert an acoustic input signal (26) into an electric input signal (28). The earpiece (18) is carried by the second housing (14) and is adapted to convert an electric output signal (30) into an acoustic output signal. The keypad (20) is carried by one of the first housing (12) and the second housing (14) and has an aperture (32) extending therethrough. In a first embodiment, the earpiece (18) is disposed behind the keypad (20) essentially opposite to the aperture (32) of the keypad (20) when the keypad (20) is carried by the second housing (14) to permit the acoustic output signal generated by the earpiece (18) to be ported through the aperture (32) of the keypad (20). In a second embodiment, the microphone (16) is disposed behind the keypad (20) essentially opposite to the aperture (32) of the keypad (20) when the keypad (20) is carried by the first housing (12) to permit the acoustic input signal (26) to be ported through the aperture (32) of the keypad (20) to be received by the microphone (16). The present invention advantageously permits the telephone set (10) to be made shorter by integrating the microphone (16) or the earpiece (18) with the keypad (20).
