<p>An EMI-proof miniature lens focusing mechanism includes a frame having four magnets mounted therearound; a lens holder holding a miniature lens therein and being enclosed in a winding element; at least one elastic element having a fixed outer portion connected to the frame and a movable inner portion connected to the lens holder, so that the lens holder is elastically and movably suspended within the frame; an upper and a lower cover located above and below the frame to assist in connecting the elastic element to the frame; and a metal housing enclosing an assembly of the upper cover, the elastic element, the lens holder, the frame, and the lower cover. The metal housing is provided at a bottom with at least one conducting plate for grounding, so that electromagnetic effects on external environment are eliminated and electromagnetic interference and electrostatic charge from external environment are isolated.</p> |
