Problems solved by technology

Because the Hall sensor is generally built into the VCM, this makes the processing technology of the VCM complicated, and the processing yield is low. The increase in motor pins in the mobile phone module factory makes the processing technology of the module complex and the cost is high.

Abstract

The invention discloses a camera module, which comprises a PCB and a hall element arranged on the PCB, wherein the hall element is connected with a control unit arranged on the PCB and sensing current is outputted according to the sensed position of a magnetic part arranged on a lens; according to the sensing current, the control unit controls driving current outputted to the coil of a voice coil motor, and the position of the lens is controlled. Besides, the invention also discloses an electronic device. The electronic device comprises the above camera module. According to the camera module and the electronic device, through arranging the hall element on the PCB and being connected with the control unit, as the hall element is not arranged inside the voice coil motor independently, connection with the control unit through a lead is only needed, the voice coil motor processing process becomes simple, the yield improvement is improved, and the manufacturing cost of the camera module and the manufacturing cost of the electronic device are reduced.

Description

technical field [0001] The invention relates to the technical field of digital photography, in particular to a camera module and electronic equipment. Background technique [0002] With the continuous development and progress of society, people's demand for photography and video recording continues to increase, and the application of digital photography is becoming more and more extensive, such as mobile phones and computer cameras. [0003] Since the common camera module is in the process of taking pictures, if the operator shakes, the camera module moves during the shooting process, and the shooting effect will be reduced. Therefore, a focus motor is generally added to improve the shooting effect. [0004] At present, the focus motor (closed-loop motor, optical image stabilization motor) used in the existing mobile phone camera module, the Hall sensor is built into the VCM (short for Voice Coil Motor, voice coil motor). The camera of the smart phone can adjust the positio...
