1. A hand part of an electric toothbrush having a brush head, the hand part comprising:
- a housing,a drive that is elastically mounted on the housing by a spring device and that can be moved with an oscillatory driving motion in at least one plane of motion, anda transmission element that is connected to the drive,wherein the spring device has different spring constants in two different directions in the plane of motion of the drive such that the oscillatory motion of the brush head has different amplitudes in these directions, and wherein the spring device and the driving frequency of the drive are adapted to one another in such a way that the brush head carries out an elliptical driving motion.

25. An electric toothbrush having a removably mounted brush head, the electric toothbrush comprising:
-
a hand part comprising a housing, a drive that is elastically mounted on the housing by a spring device and can be moved with an oscillatory driving motion in at least one plane of motion, and a transmission element that is connected to the drive and configured to transmit the driving motion to the brush head, wherein the spring device has different spring constants in two different directions in the plane of motion of the drive such that the oscillatory motion of the brush head has different amplitudes in the these directions, and wherein the spring device and the driving frequency of the drive are adapted to one another in such a way that the brush head carries out an elliptical driving motion. - View Dependent Claims (26)
