Abstract

The invention discloses a driving device, a camera module and electronic equipment. The driving device comprises: an inner carrier assembly, wherein the inner carrier assembly comprises a lens mount and a focusing coil, the focusing coil is fixed on the lens mount, the lens mount is provided with a mounting hole, and the mounting hole is used for mounting a lens; an outer carrier assembly, which annularly sleeves the outer side of the inner carrier assembly and comprises a magnet support and a common magnet, wherein the common magnet is arranged on the magnet support, and the position of the common magnet corresponds to the position of the focusing coil; and an anti-shake assembly, which is annularly arranged on the outer side of the outer carrier assembly in a sleeving mode and comprises a fixing support and an anti-shake coil, wherein the anti-shake coil is fixed to the fixing support, the anti-shake coil corresponds to the position of the common magnet, the common magnet is used for generating a magnetic field, and the focusing coil and the anti-shake coil are located in the magnetic field. According to the driving device provided by the invention, the problem of magnetic interference can be avoided.

Description

technical field [0001] The invention relates to the technical field of voice coil motors, in particular to a driving device, a camera module and electronic equipment. Background technique [0002] With the development of electronic technology, the camera performance of electronic equipment is becoming more and more powerful. Existing electronic devices can not only automatically focus, but also automatically stabilize the image when taking pictures. [0003] At present, when an electronic device takes a picture, both automatic focusing and automatic anti-shake are realized through a driving device arranged in the electronic device. Specifically, the driving device can realize the auto-focus function through the magnet used to realize the auto-focus function, and realize the automatic anti-shake function through the magnet used to realize the automatic anti-shake function. [0004] However, there is a serious problem of magnetic interference between the magnetic field gener...
