Abstract

A small electric appliance with a drive mechanism for generating an oscillatory motion of at least one working unit of the small electric appliance. The drive mechanism has a first drive component, a second drive component and a coil for producing a magnetic field that extends from the first drive component and acts on the second drive component that is movably arranged in the small electric appliance, in such a way that the second drive component is set in an oscillatory motion. The first drive component is movably arranged in the small electric appliance in order to execute an oscillatory motion in phase opposition to the second drive component. The mass centers of gravity of the first drive component and the second drive component, including parts co-moving with the first drive component or the second drive component, move on a common straight line.
