Abstract

A small electric appliance drive mechanism includes a first drive component, a second drive component, and a coil configured to produce a magnetic field extending from the first drive component and acting on the second drive component. The first drive component and the second drive component are movably arranged in the small electric appliance and adapted to oscillate in phase opposition to one another.
