A voice coil motor, comprising: a casing; a first lens support; a second lens support; a first electromagnetic drive assembly, the first electromagnetic drive assembly includes a first magnetic steel part and a phase with the first magnetic steel part a first coil cooperated to generate a first electromagnetic force, the first electromagnetic driving component is used for driving the second lens holder to move in the moving direction; and a second electromagnetic driving component is used for driving The first lens holder moves along the moving direction; the first magnetic steel part includes a first magnet and a second magnet. The first coil includes a first wire portion and a second wire portion, wherein when the first coil conducts electricity, the current direction in the first wire portion and the current direction in the second wire portion have at least a direction along the components in the opposite direction. Compared with the prior art, the present invention can solve the problem of jamming during zooming of the existing voice coil motor, and also increases the zooming stroke.
Description
technical field [0001] The invention relates to a voice coil motor, which belongs to the technical field of electronic product photography. Background technique [0002] A camera module of an electronic product generally includes a focus unit and a zoom unit arranged in a housing, wherein the focus unit and the zoom unit cooperate with each other to realize focusing and zooming of the camera module. [0003] In the prior art, when the zoom function is used, the image displayed in the camera module cannot be directly enlarged or reduced, but needs to be analyzed and calculated by software, which causes the zoom function of the camera module to take a lot of time, which in turn leads to the camera module. When the module is used for zooming, there will be a stuck phenomenon, which affects the normal use of electronic products. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a voice coil motor that reduces the stutter phenomenon during zo...
