Abstract
The present disclosure provides a lens driving apparatus comprising: a base comprising insulated first and second conductive terminals; a supporting frame provided with third conductive terminal electrically connected to second conductive terminal; a barrel comprising insulated first and second conductive wires; and elastic members made of memory alloys and comprising first and second elastic members. The first elastic member has one end fixed to supporting frame and electrically connected to third conductive terminal and another end fixed to barrel and electrically connected to first conductive wire to form current loop for driving barrel to move in positive or negative direction of optical axis. The second elastic member has one end fixed to base and electrically connected to first conductive terminal, and another end fixed to barrel and electrically connected to second conductive wire to form current loop for driving barrel to move in negative or positive direction of optical axis.
