Driving structure for optical actuator and corresponding camera module

Abstract

The present application relates to a driving structure for an optical actuator including: a first driving part adapted to mounting a camera lens; and a second driving part adapted to mounting a photosensitive assembly, wherein the first driving part and the second driving part have a common magnet, the common magnet is arranged on a first base part or a second base part, the photosensitive assembly includes a photosensitive chip, and the first driving part drives the camera lens to translate in x-axis and y-axis directions by means of the electromagnetic induction of a camera lens driving coil and the common magnet, and the second driving part drives the photosensitive chip to translate in the x-axis and y-axis directions by means of the electromagnetic induction of a photosensitive assembly driving coil and the common magnet; and the camera lens and the photosensitive chip are configured to be driven simultaneously and move in opposite directions. Further provided in the present application is a corresponding camera module. According to the present application, the anti-shake stroke and the anti-shake response speed of the camera module may be improved while keeping the volume of the module relatively small.
