Abstract
he present invention relates to a focus module. The focus module includes a substrate, a holder, and a lens. The lens is fixed on the holder. The holder faces to the substrate. The holder can be movable along the optical axis of the focus module relative to the substrate. A first magnet is fitted on the substrate. The profile of the holder is rectangle. The focus module also includes a spring element and a second magnet. The second magnet is fixed on the holder. The second magnet faces to the first magnet. The spring element is long-strip configuration. The spring element includes a first end, a second end, and at least one bend portion. The shape of the bend portion is ''⊂ ''. The spring element is fitted on the edge of the holder. The two sides of the bend portion parallel to the side of the holder. The profile of the spring element is perpendicular to the optical axis of the lens. The first end of the spring element is fixed on the holder. The second end of the spring element is fixed on the substrate. At least one of the first magnet and the second magnet can be changed magnetic polarity. The present invention also provides a method for manufacturing the focus module.
