An apparatus for driving micro shutter and aperture is provided, including a permanent magnet, a coil set, an aperture blade, a curve handle, and a base. The coil set is fixed to the base. The permanent magnet is located between the coils of the coil set. The curve handle is installed with the permanent magnet. The curve handle is linked to the aperture blade. When the current runs through the coil set, the generated magnetic force will exert a reaction force on the permanent magnet. The reaction force will generate a torque to rotate the magnet. With the curve handle linked to the aperture blade, the linkage movement can achieve the object of driving the shutter and the aperture
