Abstract
The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a drive unit having first and second drive components adapted to magnetically interact with each other, and a magnetic shielding at least partially surrounding the drive unit. Said magnetic shielding is formed by structural parts supporting the drive unit and/or transmitting drive movements of the drive unit, wherein such structural parts are made of a soft magnetic material. More particularly, a mounting frame and a transmitter frame together form a magnetic shielding cage which is movable as the mounting frame and the transmitter frame are movable relative to each other.
