    • 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.
    • 用于相对于无源元件移动有源元件的驱动单元,其中所述有源元件包括谐振器和用于激励所述谐振器的振荡的至少一个激励装置。 谐振器包括用于向无源元件施加力的接触区域。 有源元件可以通过振荡运动相对于无源元件被驱动。 谐振器包括至少两个臂,优选地为一对臂。 从共振器的连接区域开始的臂对的至少两个臂形成在谐振器的同一侧上。 在每种情况下,接触区域形成在臂的外端处,其中接触区域可以通过臂对的振荡运动而彼此移动并远离彼此。 由此,可以实现无源元件相对于有源元件的相对移动。
