Abstract
A portable voice communication device such as a cellular telephone incorporates a virtual image display module so as to provide a virtual image of displayed information that is viewable while the user is communicating via the phone. The virtual image display module is movably mounted on a hand held frame so that it can be moved from a compact storage position to an extended in-use position. Moreover, a linkage between the virtual image display module and an earphone speaker module increases the distance between the two modules to accommodate a comfortable viewing distance when the earphone is positioned adjacent a user's ear.
