an electric appliance includes an electric motor having a first oscillatory element, a second oscillatory element and an electric coil configured to generate a magnetic field to drive the first and second oscillatory elements. The electric appliance also includes a movable component and a first spring element connecting the movable component to the first oscillatory element. Notably, the first oscillatory element and the second oscillatory element are arranged to drive each other in oscillatory motions of opposite phase in response to the magnetic field of the electric coil.
