ABSTRACT:
A magnet array member with more than four poles is used for being mounted on a shutter of a camera module of a portable mobile communication device, adjacent to one side of a yoke iron of the shutter. The magnet array member includes a disc portion and a driving portion. The disc portion has more than four N poles and S poles, and an annular side face and opposite first end face and second end face. The driving portion protrudes from one of the first end face and the second end face of the disc portion in a vertical direction. Since the driving portion protrudes from one end face of the disc portion, the disc portion can form more than four N poles and S poles when magnetized, thereby being convenient for mass production.
