Abstract

A dual-stage miniature actuating apparatus comprises: a lens holder, a lens received in the holder, a carriage for holding the holder in a movable manner, at least one magnetic unit mounted on the holder, at least one coil unit furnished on the carriage and corresponding to the magnetic unit, and at least two magnetic conductive units respectively located at a front side and a rear side of the holder. By applying electric current to the coil unit to react with the magnetic field of the magnetic unit, a force will be generated for pushing the holder, so as to move the lens to a predetermined position for achieving either zooming or focusing function. In addition, the magnetic conductive units located in front and behind of the holder can induce the magnetic unit on the holder to stay at their locations. Even if the current of the coil unit is turned off, the lens will still be able to stay at the location of one of the magnetic conductive units firmly. Such that, the goal of less power consumption can be achieved.
