Abstract
An exemplary shutter device includes a base having an aperture defined therein, a shaft mounted on the base, a magnetic element, a shutter blade, a first wire coil and a second wire coil. The magnetic element is connected to the shaft and rotatable around the shaft. The shutter blade is coupled to the shaft and jointly rotatable with the magnetic element. The first wire coil and the second wire coil are mounted on the base arranged on two sides of the magnetic element. The first and second wire coils are configured for driving the magnetic element to rotate, thereby moving the shutter blade to selectively expose the aperture or cover the aperture.
