<p>An audible vibratory biased reed assembly having the properties of being activated or commencing vibration upon being subjected to a predetermined energy level. This assembly utilizes a straight, flat, elongated, closed or clapping reed, to produce a clatter or buzzing sound, with the reed being biased through application of a bias force to one edge to distort its flatness adjacent its free extremity. The bias force is applied by an angular transverse bridge which substantially triples the frequency of the mechanical clatter.</p> |
