Abstract
A vibration device comprises a motor having a stator and a rotor each having one or more magnetic elements. A magnetic element on at least one of the rotor and the stator comprises an electromagnet which can be supplied with an electric current so as to interact with a magnetic element on the other of the rotor and the stator to cause rotation of the rotor with respect to the stator; and the one or more magnetic elements of the rotor, considered together, have a center of mass which is offset from the axis of rotation of the rotor. The rotor and the stator are arranged in, or together form, a cavity containing a liquid.
