The top-support is fixed on the bottom of LCD lens.
The drive mechanism is any one in voice coil motor, memorial alloy motor and ultrasonic motor, the voice coil loudspeaker voice coil
Motor is any one in spring-piece type structure, ball-type structure and frictional structure.
After said structure, the present invention is that top-support is set between optical lens and LCD lens, passes through top
The annulus top of support is mutually extruded, contacted or separated with the lower surface of LCD lens by the movement of adjustable pedestal, liquid crystal
When camera lens is extruded by support annulus, after the dress liquid inside LCD lens is squeezed, liquid flowing is so as to form new song
Rate size, curvature is bigger, and the distance that can be shot becomes near, is closely focused so as to realize, the present invention can photograph 2CM recently.Phase
Compared with the existing camera lens that focusing is realized by changing liquid crystal curvature, the present invention controls Curvature varying, its structure using mechanical system
Simply, easily realize, and complicated circuit need not be set, reduce energy consumption, reduce the fraction defective of product.
In addition, the present invention can also finely tune the angle of top-support by the movement of driving mechanisms control adjustable pedestal, from
And make the camera lens that there is the function of stabilization.
