Abstract

The invention discloses an aperture assembly, a camera and electronic equipment, and the aperture assembly comprises a pedestal which is provided with an accommodation cavity, and the bottom wall of the accommodation cavity is provided with a light through hole; shading pieces which are arranged in the containing cavity, and the multiple shading pieces are evenly distributed in the circumferentialdirection of the light through hole; a piezoelectric motor which is arranged in the containing cavity, and the piezoelectric motor drives the anti-dazzling screen to move in the radial direction of the light through hole so as to change the light inlet area of the light through hole. In the aperture assembly, a piezoelectric motor is arranged, stepless change of the moving distance of the piezoelectric motor can be achieved by changing the number of driving pulses of the piezoelectric motor, meanwhile, the piezoelectric motor can drive the shading piece to move, stepless change of the movingposition of the shading piece can be achieved, and stepless change of the light inlet area of the light through hole can be achieved.

Description

technical field [0001] The present application relates to the technical field of cameras, and in particular to an aperture assembly, a camera and electronic equipment. Background technique [0002] In the related art, when the aperture assembly adjusts the light-incoming area, it can only realize two-level or three-level changes, but cannot achieve infinite changes in the light-incoming area.
