Abstract
A magnetic component having at least four poles is applied to a shutter of a photographing module of a portable mobile communication device and is installed at the yoke iron side of the shutter. The magnetic component includes a disc part and a driving part. The disc part forms at least four poles of N-pole and S-pole, and the disc part has a ring side surface and the corresponding first end surface and second end surface. The driving part extrudes from one of the first and the second end surfaces of the disc part along the vertical direction. By the aforementioned designed that the driving part extrudes from the end surface of the disc part, at least four poles of N-pole and S-pole can be formed on the disc part when a magnetic field is applied, thereby facilitating mass production.
