Abstract

The embodiment of the invention discloses a control method and device and electronic equipment, which are applied to the electronic equipment. The electronic equipment is internally provided with a liftable camera module, a detection assembly and a driving device; the detection assembly comprises at least one magnetic field sensor and a magnet. The magnet is fixedly connected with the liftable camera module. The method is characterized by comprising the following steps: in the process that the driving device drives the liftable camera module to ascend, acquiring magnetic field change information through the at least one magnetic field sensor, and adjusting the rotating speed of the driving device based on the magnetic field change information. Through the method, the rotating speed of thedriving device for driving the liftable camera module can be adjusted on the basis of the detected magnetic field change information, so the problem that the liftable camera shrinks automatically dueto long-time high-rotating-speed stalling of the driving device is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a control method, device and electronic equipment. Background technique [0002] With the continuous development of electronic technology, electronic devices such as mobile phones and tablet computers have become a necessity for people's life and work. In order to meet people's needs for screens, full-screen mobile phones have gradually become the mainstream of the market. The display effect, the liftable camera module came into being. [0003] The liftable camera module is mainly driven by the stepping motor in the electronic device, and the stepping motor can control the rise and fall of the liftable camera module and the magnet. During the lifting process of the liftable camera module, the magnetic flux detected by the Hall switch in the electronic device will change with the movement of the magnet, so the magnetic flux detected by the Hall switch can be used t...
