Abstract
A resonator for applying vibrational energy to a member, for example a photoreceptor belt or developer/donor member, includes an energy transmitting horn member having a platform portion and a horn portion, the horn portion including a contacting portion for contacting a surface of the member, and a piezoelectric material in association with the horn member for driving the horn member to vibrate, the piezoelectric material responsive to a voltage signal from a voltage source. The piezoelectric material is a composite of at least one piezoceramic material and at least one of a polymer or air, and has a 1-3 configuration. By the selection of a piezoceramic/polymer composite material having the specified configuration for use as the vibratory energy producing source, or transducer, of a resonator, improved piezoelectric material performance is achieved, particularly with respect to control and/or elimination of undesired transverse vibration, and manufacturing complexity is reduced.
