ABSTRACT:
A focus driving apparatus with impact resistance is provided, including a lens carrier seat, a fixed base, a hanging element set, and a shake-resistant element set. The lens carrier seat is for carrying a lens. The hanging element set further includes a plurality of metal wires. The shake-resistant element set includes at least a soft resilient plate. One end of the metal wires of hanging element set is fixed to the lens carrier seat, and the other end penetrates the holes on the soft and resilient plate on the fixed base and is fixed to the shake-resistant element set. The shake-resistant element set can absorb the external impact force by deformation to provide protection to the hanging element set and lens carrier seat.
