ABSTRACT:
A telephone set (10) comprises a housing (12), a microphone (16) and a keypad (20). The microphone (16) is carried by the housing (12) and is adapted to convert an acoustic input signal (26) into an electric input signal (28). The keypad (20) is carried by the housing (12) and has an aperture (32) extending therethrough. The microphone (16) is disposed behind the keypad (20) essentially opposite to the aperture (32) of the keypad (20) 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) with the keypad (20).
