  • Patent number: 10892699
    Abstract: An inverse-movement-type voice coil actuating apparatus includes a case structure, a stationary lens module, and a movable image sensing and focusing assembly. The case structure has a case. The lens module is assembled in the case to define an optical axis. The image sensing and focusing assembly is received in the case and moves back and forth along the optical axis with respect to the lens module to focus. Thus, the path of the back-and-forth movement of the image sensing and focusing assembly can be ensured to remain consistent with the optical axis and the lens can be pre-screwed without dropping the dust during the assembly process to further increase the production yield.
    Type: Grant
