Abstract
A pivotable flip element for use with hand-held radiophone units is specially configured to provide highly efficient coupling of acoustic energy into and out of the radiophone by virtue of an acoustic horn precisely formed as an interior cavity of the planar pivotable element. When arranged as a device for coupling acoustic energy into a microphone fixedly mounted to the radiophone housing, incident sound is directed from the horn mouth to its throat section, and thereafter through a rotary acoustic joint to an input channel to the microphone. The continuously rotatable rotary joint accommodates flip element rotations, allowing for the dualpurpose operations of protecting and covering the radiophone keyboard when not in use, and efficient input sound coupling when deployed.
