Abstract
Provided is a lens assembly, including: a first base including a first bottom plate, and first and second side plates; a lens; and first and second memory alloy wires. The first memory alloy wire includes ends connected to the first side plate and the lens. The second memory alloy wire includes ends to the second side plate and the lens. Both the first and second memory alloy wires are perpendicular to an optical axis of the lens. According to the present invention, the first and second memory alloy wires are energized to deform, to drive the lens to reciprocate between the first and second side plates to achieve optical image stabilization. Therefore, there is no problem of magnetic field interference, and stability thereof is high. Such driving leads to a simple structure and convenient assembling without an additional Hall element, and has high usage reliability in a special environment.
