Abstract

The application discloses an aperture assembly, a camera, and electronic equipment, wherein the aperture assembly includes: a base, the base has an accommodation cavity, and a light hole is provided on the bottom wall of the accommodation cavity; There are a plurality of shading sheets, and the plurality of shading sheets are evenly distributed along the circumferential direction of the light through hole; the piezoelectric motor is arranged in the housing cavity, and the piezoelectric motor drives the shading sheets to move along the radial direction of the light through hole to change The light entrance area of ​​the light hole. According to the diaphragm assembly of the present application, a piezoelectric motor is provided, and the infinite change of the moving distance of the piezoelectric motor can be realized by changing the number of driving pulses of the piezoelectric motor. At the same time, the piezoelectric motor can drive the shading sheet to move, thereby realizing the The stepless change of the moving position can further realize the stepless change of the light entrance area of ​​the light hole.
