Subject matter disclosed herein may relate to lens actuators used, for example, in auto-focus and/or vibration compensation systems of digital cameras.

Multi-drive mechanism lens actuator

A lens actuation device for an optical system includes a housing, a carrier at least partially installed in the housing, and a plurality of transducers arranged around the carrier in the housing. All the transducers are coupled with the mount, and at least one transducer includes at least one magnet and at least one coil. At least one transducer includes at least one yoke. All the transducers when powered on may generate independent or consistent movement to cause the mount to make linear movement, rotation, or both relative to the housing. An optical system adopting the lens actuation device and a camera using the same are also presented. The device of the present invention uses the transducers to drive the carrier, such that the lens set is driven to make linear movement, rotation, or both, thereby achieving the flexible manipulation of the lens.

Lens actuation device, optical system and camera

The subject matter disclosed herein relates to an actuator to adjust a position of a lens.

Miniature actuator and optical apparatus

There is provided an actuator used in an optical system comprising a housing, a carrier disposed at least partly inside the housing, and a plurality of linear motion transducers coupled to the carrier and substantially evenly spaced around the carrier within the housing. Each linear motion transducer is able to produce linear motion when energized displacing the carrier relative to the housing to produce linear motion, tilting motion, or both of the carrier.
