The invention discloses a voice coil motor, a camera module and an electronic device. The voice coil motor comprises a plastic base, a plastic shell, a coil base and a magnetic body. A plastic terminal is arranged on the plastic base; the plastic terminals and the plastic base are integrally formed by injection molding; metal pins are arranged on the plastic terminals; the plastic shell covers theplastic base, a containing space is defined by the plastic shell and the plastic base, the coil base comprises a lens carrying base arranged in the containing space and a coil body arranged on the lens carrying base in a sleeving mode, the coil body is electrically connected with the metal pins, and the magnetic body surrounds the coil body and is arranged in the containing space. According to the invention, the plastic shell is used for replacing a metal shell in the prior art, the purpose of reducing electromagnetic interference generated by the magnetic body to the coil body is achieved, the accuracy of automatic focusing or zooming of the camera module is improved, the plastic terminal and the plastic base are integrally formed in an injection molding mode, and the assembly cost and the risk of poor assembly can also be reduced.
Description
technical field [0001] The invention relates to the technical field of photography, in particular to a voice coil motor, a camera module and electronic equipment. Background technique [0002] At present, the voice coil motor is generally used to drive the lens part of the camera module to focus or zoom, but the voice coil motor will generate electromagnetic interference (Electromagnetic Interference, EMI) during the driving process. However, the shell of the existing voice coil motor is generally made of metal shell, which cannot shield electromagnetic interference, which affects the accuracy of autofocus or zoom of the camera module, and the terminals on the base of the voice coil motor are assembled separately from the base, resulting in assembly costs. Increase, there is a risk of poor assembly, such as: easy bending, oxidation, and weak soldering during terminal assembly. [0003] In view of this, it is necessary to provide a voice coil motor, a camera module and an el...
