Abstract
A vibratory apparatus, including a housing having an internal chamber, wherein the internal chamber includes a lever having a first end and a free second end, and a piezoelectric element adapted to deform in response to an applied voltage, wherein deformation of the piezoelectric element displaces the free second end of the lever, and wherein displacement of the free second end of the lever within the internal chamber imparts a vibration to the housing.
