Abstract
The present invention provides a lens driving device and an electronic device, wherein the lens driving device comprises a housing and a lens assembly; the lens assembly includes a lens module and a shell for accommodating the lens module; a bottom wall of the housing is formed an arc-shaped rail; the lens driving device further includes a ball disposed between the housing and the shell and located in the arc-shaped rail; a first driving structure for driving the lens assembly to rotate around an optical axis is further arranged between the housing and the shell; and the first driving structure includes a magnet and a coil opposite to the magnet. The present invention realizes rotation of the lens module around the optical axis direction, thus avoiding the swaying of the lens driving device caused by hand movement, achieving image stabilization, and improving the imaging effect of the lens module.
