This invention is related to a focusing structure, which can be applied into an, image device. The focusing structure comprises a base, a lens seat and an electromagnetic dynamic loop. The electromagnetic dynamic loop is a hollow loop and made by a magnet, at least a yoke and a coil, wherein the coil surrounds the yoke. When a current occurs in the coil, due to the direction of the current and the direction of the magnetic field, the coil will move through a rod of the base. Hence the image device has the focusing function.
