Abstract

This application relates to a coil structure, a voice coil motor and a camera module, suitable for a voice coil motor, including: a first coil group, the first coil group includes coils symmetrically distributed on the center points of the sides of a polygon, and the polygon is in the form of A centrally symmetrical regular polygon; the second coil group, the number of coils in the second coil group is an integer multiple of the number of coils in the first coil group, and the coils in the second coil group are evenly distributed inside the first coil group, the second coil group The first coil group is connected with the second coil group. Traditional voice coil motors have only one pair of coils in the X direction or Y direction. The stroke of the voice coil motor is limited, the adjustment accuracy of the lens is not high, and the power consumption of the voice coil motor for anti-shake compensation is relatively high. However, the voice coil motor in this application includes two sets of coils, and the two coil sets can receive current independently, in parallel, or in series, because each coil set can have a smaller motor stroke, so The adjustment accuracy of the lens is higher.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a coil structure, a voice coil motor and a camera module. Background technique [0002] With the continuous development of camera technology, people's requirements for taking pictures of electronic equipment cameras are increasing day by day. The anti-shake voice coil motor in traditional electronic equipment or cameras has a limited stroke, low anti-shake accuracy, and high power consumption when performing anti-shake compensation through the anti-shake voice coil motor. As people's requirements for taking pictures of electronic devices are increasing day by day, how to further improve the quality of taking pictures of electronic devices or cameras and meet the higher needs of users for taking pictures is an urgent problem to be solved. Contents of the invention [0003] Embodiments of the present application provide a coil structure, a voice coil motor, and a cam...
