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.
