Abstract: A variable aperture, a camera module, and an electronic device are provided. The variable aperture includes a base, a fixed plate connected to the base, a rotation plate disposed around the fixed plate, a plurality of blades rotatively connected to the fixed plate and the rotation plate, a first SMA wire, and a second SMA wire. The first SMA wire or the second SMA wire is configured to shrink when power is on, to drive the rotation plate to rotate relative to the fixed plate. Each of the blades rotates relative to the fixed plate and slides relative to the rotation plate, so that an aperture of the aperture hole changes.
