Abstract:
A variable aperture (60), a camera module (100) and an electronic device (1). The variable aperture (60) comprises a fixing base (630), a rotating support (63), a plurality of blades (65) and a first cover body (732). The rotating support (63) is located on an inner side of the fixing base (630) and is rotationally connected to the fixing base (630), and the rotating support (63) defines a space (610). The plurality of blades (65) jointly define a light-transmitting hole (650), the light-transmitting hole (650) communicates with the space (610), and each blade (65) is rotationally connected to the fixing base (630) and is slidably connected to the rotating support (63). The first cover body (732) is fixed to the fixing base (630) and is located on the side of the blades (65) away from the fixing base (630), and the first cover body (732) is made of a metal material. Thus, the first cover body (732) has relatively high structural strength. The blades (65) are not easily damaged by the deformation of the first cover body (732), and the variable aperture (60) has the advantages of a long service life and good reliability.
