ABSTRACT:
A device for generating controlled vibration in an uncontrolled temperature environment includes a driving circuit that generates a signal having a first frequency and has a temperature-sensitive driving unit, a vibratory element coupled to the driving unit that vibrates at the first frequency according to the generated signal, and a temperature control circuit to control the temperature of the driving unit.
