Abstract

The invention provides an anti-shake system for miniature camera shooting, which is mainly characterized in that a flexible circuit board is arranged at four inner peripheries and the top of the system, and comprises two pairs (four) of shake-proof coils and a focusing coil which are accommodated in the flexible circuit board; a bracket is arranged with four corner seats, and the bracket is attached to the inner edge of the flexible circuit board; the four shake-proof coils are arranged among the four corner seats of the bracket, and every two shake-proof coils are oppositely arranged in series to form the stator part of the hand shock prevention system. In addition, a magnetic yoke is arranged around a camera shooting objective lens bearing, four magnets are arranged on the periphery of the objective lens bearing respectively, and the four magnets and the four shake-proof coils are arranged at intervals to form the mover part of the hand shock prevention system; and an upper elastic sheet and a lower elastic sheet are respectively connected with the stator part and the rotor part to form the anti-hand-shake system capable of independently moving in the X-Y-Z axis.

Description

technical field

[0001] The invention relates to an anti-shake system for miniature cameras, in particular to an anti-shake focusing motor device that can be used as a three-dimensional three-axis magnetic circuit system, which can be widely used in miniature photographic equipment or matched with mobile phone camera systems Equipped, it has the advantages of saving parts and assembly costs, and not occupying a volume. Background technique

[0002] While photographic devices are becoming thinner and smaller, the technology of motors for micro-camera modules is becoming more and more important. Especially when mobile phones become an indispensable item in life, the need for micro-motors on mobile phones is even greater. Therefore, the requirements for the anti-shake technology of micro motors are constantly increasing.

[0003] The Optical Image Stabilization (OIS) in the camera mainly uses the internal lens or photosensitive element to correct the movement of the camera such...
