20150070765 | DUST-FREE LENS DRIVING APPARATUS - A dust-free lens driving apparatus includes a lens holder for holding a lens, a housing having a central bore in which the lens holder moves, and a film having a first contact region, a second contact region and a buffer region. The first contact region is defined by a first peripheral portion of the film and is used to sealingly attach the film to and around the lens holder. The second contact region is defined by a second peripheral portion of the film and is used to sealingly attach the film to and around a connection portion of the housing. The buffer region is defined by a remaining region of the film between the first and second contact regions and is used to seal an exit of a gap between the lens holder and the housing. | 03-12-2015 |
