Abstract:
A wireless communication device (10) is provided for maintaining acceptable acoustic coupling, increasing display and data input device capability and increasing antenna performance to encourage further miniaturization and weight reduction thereof. Two moveable housing portions (12) and (14) are moveable between a closed (18) and an open (20) housing position and matively engage to provide an expandable housing while aligning earpiece (26) and microphone (28) transducers on a center axis (30) of the device (10). Paging and radiotelephone functions of the device are configured responsive to the position of the housing portion (12). The housing portion has a lens for viewing a display (46) thereunder and keycaps for actuating a keypad (54) thereunder when the housing portion (12) is in the closed housing position (18). An antenna (56) is extendable beyond the moveable housing portion (12).
