Abstract
A lens driving device, including a base, a support frame suspended above the base, a lens holder for mounting a lens, a pair of conductive elastic sheets, a support suspension wire, a circuit board, a focusing circuit board, a shared magnet, a focusing coil and an anti-shake coil. The conductive elastic sheets are elastically connected to the support frame and lens holder. The circuit board includes a stationary portion and a movable portion connected thereto. The support suspension wire elastically connects the conductive elastic sheet with the movable portion, and can only support the movable portion. The focusing circuit board fixedly and electrically connects the conductive elastic sheet with the stationary portion, and electrical connection is led from the circuit board, ensuring stable and reliable electrical connection between the conductive elastic sheet, focusing circuit board and circuit board. An electronic device including the lens driving device is provided.
