Abstract

The invention provides a voice coil motor. The voice coil motor comprises a frame, a magnetic part arranged on the frame, a coil assembly arranged in an inner cavity of the frame, a first elastic part, a flat coil and a base, wherein the magnetic part is arranged around the coil assembly in a surrounding mode, the flat coil is arranged on the base, the frame is arranged on the flat coil, the first elastic piece comprises a first connecting ring connected to the coil assembly and a first positioning part, the coil assembly is connected to the frame through the first positioning part, the first positioning part is used for moving and resetting the coil assembly relative to the frame, a positioning mechanism is arranged between the frame and the base, the positioning mechanism is used for positioning the coil assembly, and the positioning mechanism is used for moving and resetting the frame relative to the base. The invention further provides a camera provided with the voice coil motor and electronic equipment.

Description

technical field [0001] The invention relates to the field of electric control devices, in particular to a voice coil motor, a camera provided with the voice coil motor, and electronic equipment provided with the camera. Background technique [0002] With the rapid development of the mobile phone industry and faster technological innovation, consumers have increasingly stringent requirements for mobile phone camera functions, which poses greater challenges to cameras. The motors in mobile phone cameras currently on the market generally have AF (Auto Focus) motors and OIS (Optical image stabilization) motors; among them, the OIS motors used in high-end mobile phones are divided into ball motors and shrapnel suspension wire motors. For the motor, the shrapnel suspension wire motor has a reliable open-loop linear current control because of the force balance system of the linear structural reaction force, while the ball motor has only the reaction force of the static and dynamic ...
