Abstract
The present application provides an image sensor driving device including a housing, an elastic support assembly, an image sensor assembly, a driving coil, and a magnet. The elastic support assembly includes a first circuit plate, a second circuit plate provided around the periphery of the first circuit plate and is fixed and electrically connected to the first circuit plate, and an elastic member fixed to the housing. The second circuit plate is directly opposite and spaced apart from the magnet, and the driving coil is formed on the second circuit board by material additions or etching, thereby effectively simplifying the assembly process and cost and saving the stacking space, which is conducive to the design of the magnetic circuit to enhance the BL value. Besides, the weight of the driving coil is effectively reduced, and the moving mass is about 10% lower than that of the voice coil.
