Abstract
Provided is a driver assembly for driving a moving component. The driver assembly includes: a motor; a transmission portion; and an execution portion; and a shape memory alloy wire connecting the moving component with the execution portion. The moving component is slidably connected to the transmission portion and spaced apart from the execution portion. The motor can drive the transmission portion to lead the execution portion to move along a first direction, in such a manner that the moving component is driven by the shape memory alloy wire to move along the first direction. The shape memory alloy wire is configured to drive the moving component to move along the first direction relative to the execution portion under an external electrical signal. When being applied in the camera module, the driver assembly can drive the movable lens assembly to move along an optical axis, facilitating the zooming and autofocus.
