Abstract
A user interface construction is provided for a portable terminal of a communication system. It comprises a circuit board (301, 603) having a first surface as well as a keypad (303, 304), a display unit (307) and a loudspeaker (306) on said first surface. Additionally it comprises an outer cover (311) arranged to essentially cover said keypad (303, 304), display unit (307) and loudspeaker (306). It comprises also between the keypad (303, 304), display unit (307) and loudspeaker (306) and the outer cover (311) an extended display frame (308, 602). It is electrically conductive, coupled to a ground potential member (604) appearing on the circuit board (301, 603) and arranged to hold the keypad (303, 304), display unit (307) and loudspeaker (306) in place with respect to the circuit board (301, 602). Additionally it is arranged to essentially cover the keypad (303, 304), the display unit (307) and the loudspeaker (306) so as to protect them against electrostatic discharges.
