Problems solved by technology

Although the size of the variable aperture structure is small, it still cannot meet the thickness requirements of some electronic devices, and has the following problems:
[0006] (1) Since the variable aperture structure is to control the rotation of the rotatable blade to a predetermined position to change the size of the aperture, the rotation is more complicated, which increases the difficulty and precision of the control of the rotation, that is, increases the demand for the control accuracy of the motor , which will increase the complexity and cost of the preparation process
[0007] (2) The magnet in the motor that controls the focus of the lens in the camera will generate a magnetic field, which can easily cause magnetic interference to the motor that controls the rotation of the rotatable blade, affecting the normal working state of the motor, and then affecting the

The invention further discloses a camera module comprising the variable aperture structure, the size of the camera module is small, and the imaging quality is high. The invention further discloses an electronic device comprising the camera module, the electronic device is relatively thin, andhigher-quality pictures can be taken.

Description

technical field [0001] The present invention relates to an aperture structure, in particular to a variable aperture structure, a camera module based on the variable aperture structure, and electronic equipment based on the variable aperture structure and / or the camera module. Background technique [0002] As an essential part of a camera, the aperture can significantly improve the camera's photographic effect. Specifically, by adjusting the structural size of the aperture to control the amount of light passing through the lens, the depth of field of the camera can be controlled, and the background blur effect can be improved, thereby improving image quality. [0003] As electronic devices such as mobile phones and tablet computers become thinner and thinner, the size of the camera installed in the electronic device needs to be as small as possible to accommodate the thickness of the electronic device. In the prior art, in order to adapt to the thickness of the electronic de...
