A drive unit for the movement of an active element with respect to a passive element, wherein the active element includes a resonator and at least one excitation device for exciting oscillations of the resonator. The resonator includes contact regions for exerting forces onto the passive element. The active element may be driven with respect to the passive element by way of oscillating movements. The resonator includes at least two arms, preferably a pair of arms. The at least two arms of an arm pair, proceeding from a connection region of the resonator, are formed on the same side of the resonator. In each case the contact regions are formed at the outer ends of the arms, wherein the contact regions may be moved to and away from one another by way of oscillating movements of the arm pair. Thereby, a relative movement of the passive element with respect to the active element may be effected.
A drive unit comprising an active element which moves with respect to a passive element, wherein the active element comprises a resonator and at least one excitation means for exciting oscillations of the resonator, the resonator comprises contact regions for exerting forces onto the passive element, and the active element may be driven with respect to the passive element by way of oscillating movements of the contact regions, wherein the resonator comprises at least two arms, preferably a pair of arms, and the at least two arms, extending from a connection region of the resonator, are formed on the same side of the resonator, in each case the contact regions are formed at the outer ends of the arms, the contact regions are movable towards one another or away from one another by way of oscillating movements of the arm pair, and thereby a relative movement of the passive element with respect to the active element may be effected.
