Abstract: An aperture assembly includes a driving mechanism, a support base, and a plurality of blades. A first light entering hole is disposed on the support base, all the plurality of blades are rotatably connected to the support base, the plurality of blades form a light transmission hole, the light transmission hole is in communication with the first light entering hole, and all the plurality of blades are connected to the driving mechanism. Driven by the driving mechanism, all the plurality of blades are rotatable relative to the support base, to adjust an amount of light entering the light transmission hole.

Abstract: An aperture module, a camera module, and an electronic device are disclosed. The aperture module includes a base, a blade group, a gear carrier, and a driving member. A light passing hole is formed in the base. The blade group is disposed on the base and includes a plurality of blades. A light entering hole opposite to the light passing hole is formed among the plurality of blades. The driving member is connected to the gear carrier. The driving member is capable of driving the gear carrier to move relative to the base. In a process in which the gear carrier moves relative to the base, the gear carrier drives the blades in the blade group to rotate relative to the base in the direction towards or away from the center of the light entering hole, to adjust the size of the light entering hole.
