A personal hygiene device has a resonant motor and a motor control unit for applying a periodic voltage signal with a driving frequency at the resonant motor for driving the resonant motor into an oscillating motion with an oscillating frequency equal to the driving frequency. The motor control unit comprises a synthesizer circuit for digitally synthesizing the periodic voltage signal from voltage pulses of variable length provided with a pulse frequency higher than the driving frequency such that at least two voltage pulses are applied at least in one of two half cycles of each period of the periodic voltage signal.

A shaving head for an electric shaving apparatus, having an under cutter comprising at least one blade which is drivable in at least one direction of movement relative to an outer cutter. To achieve a good shaving result while at the same time protecting the skin to be best possible effect, it is proposed providing the blade with an outer boundary section which is raised in relation to the cutting edge, faces in the direction of the outer cutter and inclines upwardly from the cutting edge toward the outer cutter.

The invention is directed to a shear system for an electric hair removing apparatus, in particular for an electric shaving apparatus, including at least one shearing unit having an outer cutter and an undercutter that are set in relative motion. The shear system of the invention includes at least one feeding device arranged to precede the shearing unit and is characterized in that the feeding device is set in motion relative to the outer cutter.
