Abstract
A lens driving device includes a fixing bracket; first and second support frames; a rotation assembly including first and second rolling balls so that the fixing bracket and the first support frame are spaced apart from each other and form a rotational connection about a first direction, and the first and second support frames are spaced apart from each other and form a rotational connection about a second direction; a driving assembly for driving the fixing bracket to rotate relative to the first and second support frames about the first direction and for driving the first support frame to rotate relative to the second support frame about the second direction; a flexible circuit board; and first and second elastic support components. The lens driving device reduces the height of the overall structure, and effectively reduces the height of the lens driving device.
