Abstract
A small, lightweight, efficient, quiet electric shaver is provided in which one or more piezoelectric drivers are mechanically coupled to a cutting blade. The cutting action of the blade is generated by the piezoelectric drivers which, when electrically energized, oscillate at a predetermined frequency. The piezoelectric driver is electrically energized by a regenerative drive circuit. Hair shafts, which protrude from the surface to be shaved through a perforated foil member, are sheared at their base by the oscillating action of the blade.
