Abstract: A single-lens mechanic zero tilt angle adjustment method is disclosed, comprising a preparation step, an adjustment step and an engagement step, wherein preparation step comprising: disposing a lens at a voice coil motor (VCM), with a gap between the bottom of VCM and an engagement surface of an adaptor and the lens optical axis forming a tilt angle with the normal the adaptor plane; adjustment step comprising: adjusting the tilt angle by moving VCM and/or adaptor to zero degree and the optical axis perpendicular to the adaptor plane; and engagement step comprising: adhering the bottom of VCM to an engagement surface of adaptor to obtain a structure of single-lens mechanic zero tilt angle. As such, the adaptor plane is engaged to the image sensor, and the tilt angles between the lens optical axis o and the axis of the image sensor is zero to improve imaging quality.

Abstract: A dust-proof assembly for the lens driving device is disclosed, including at least a ring-shaped element and at least a flexible element. The at least a ring-shaped element is disposed with a tiny gap surrounding a lens assembly. The at least a flexible element fixes the at least a ring-shaped element to a bottom. The dust-proof assembly is able to prevent external foreign objects, such as particles or dusts, from falling onto a sensor element.
