Zusammenfassung:	A lens drive device, including a screening can (01); periphery of the inside an upper cover (05) and driving magnets (08); a lens support (06) is further provided inside the screening can (01); a driving coil (07) is winded at a outer periphery of the lens support (06); the driving magnets (08) include a first driving magnet and a second driving magnet; a structure of each of the first driving magnet and the second driving magnet includes corner segment (082) distributed along a corner of the screening can (01) and edge segment (081) distributed along an edge of the screening can (01); and the first driving magnet and the second driving magnet are in a central symmetry around an axial center of the lens drive device. By improving a structure of the lens drive, the lens drive device has beneficial effects of low power consumption and large driving force.
