Title: PIEZOELECTRIC MOTORS AND MOTOR DRIVING CONFIGURATIONS
Abstract:
A shaver for cutting facial and body hair comprising: at least one blade head (22) comprising at least one cutting blade (24) having a cutting edge (26) for cutting hair; a coupling surface (34) coupled to the at least one blade head so that when the coupling surface moves, the blade head moves; at least one piezoelectric motor (20) having a motor-coupling surface region (48) resiliently pressed to the coupling surface; and a driving circuit that energizes the at least one piezoelectric motor (20) and excites thereby vibrations in the motor-coupling surface (48) of the piezoelectric motor that moves the coupling surface (34) and thereby the blade head and at least one cutting blade.
