Abstract

A radiotelephone having a hinged flip cover that protects a keypad when closed and assists the operation of the microphone when open. The key pad and display are located on the same side of the radiotelephone and a microphone and speaker are on the other side. The flip cover is hinged to a bottom edge of the radiotelephone. The hinge pivots through an angle of greater than 180 degrees. Accordingly, the hinge folds over at least a portion of the keypad when closed and unfolds to the opposite side of the radiotelephone to form an angle of less than 180 degrees with that opposite side. A microphone and antenna may be located within the flip cover.
