Abstract
The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a magnetic linear drive unit having first and second drive components supported for linear displacement relative to each other and adapted to magnetically interact with each other, wherein a drive support is provided for supporting the drive unit onto a mounting structure. The drive support supporting the drive unit onto a mounting structure of the installation environment is adapted to provide for at least one axis of rotation for the drive unit allowing said drive unit to rotate relative to the mounting structure, said axis of rotation being spaced apart from the drive unit to provide for a transmission ratio increasing or decreasing the oscillation amplitude of the functional element driven by the drive unit vis-à-vis the oscillation amplitude of the drive unit.
