摘要： A lens driving device comprises an annular magnet carriage acting as the outer frame of the lens driving device. A magnet and a coil are disposed in the annular magnet carriage. A lens holder with a lens is disposed in the central circular hole of the annular magnet carriage. A front spring with front gasket is disposed in front of the lens holder, and a rear springs with rear gasket is disposed in back of the lens holder, and the spring strings of the front and rear spring are located centrosymmetrically to avoid the rotation offsetting caused by the distortion and to prevent the small offsetting of the optical axis when the lens holder is moving. The structure of nested seamless connection between the rear spring and the base can prevent small matter and disturbing optical entering into the lens driving device Four triangular prism-shaped magnets are respectively disposed in the four corners of the cavity of the annular magnet carriage. The annular magnet carriage, the front spring, the rear spring, the front gasket, the rear gasket, the lens holder, and the base are all in the shape of flat plate and nested connect with each other to form a position mechanism.
