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).

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).

A cellular speakerphone (100) includes a housing (101) containing a transceiver circuit (203), a processor and switching circuit (205), a coupler (209), and a hands-free user interface (207). The processor and switching circuit (205) and the hands-free user interface (207) operate the cellular speakerphone (100) in a default hands-free mode that is automatically interruptable to permit the cellular speakerphone (100) to operate in a handset mode when an optional handset (127) is operably coupled to the cellular speakerphone (100) via the coupler (209).

Improved backlighting apparatus evenly illuminates positive and negative LCDs under all ambient lighting conditions. Incandescent lamps (301-304) provide light for distribution by a light pipe (101). The bottom of the light pipe (101) is selectively painted white to reflect light to the top of the light pipe (101) while the unpainted areas reflect light internal to the light pipe (101), controlling hot and dim spots. The corners of the light pipe (101) near the lamps (301-304) are dual angled to reflect the light into the center of the display. The burn-out of a lamp (301-304) will not substantially affect the even lighting capabilities of the apparatus.
