Kind Code:
A3
Abstract:
A device (7) for producing mechanical vibrations comprises a component (19) displaceable under the action of a magnetic field and a coil configuration (14) surrounding the component (19) and energy supply means (21) for supplying energy to the coil configuration (14), wherein magnetic fields may be generated by means of the coil configuration (14) for displacing the component (19) to and fro and wherein counterforce means (22) are provided, which constantly exert counterforces on the component (19) and form an oscillatory system (27) with the component (19).
