The invention provides electronic equipment and a method for determining the position of a lifting lens module. The electronic equipment comprises an equipment body, a lifting lens module, a magnet, amulti-axis magnetometer and a control chip, wherein the equipment body is internally provided with a cavity, one side of the equipment body is provided with a through hole, the cavity is communicatedwith the outside, the lifting lens module is accommodated in the cavity, the lifting lens module is telescopically arranged in the through hole, the multi-axis magnetometer is arranged correspondingto the magnet, one of the magnet and the multi-axis magnetometer is arranged on the elevating lens module, the other one is arranged on the equipment body, the multi-axis magnetometer is used for detecting the magnetic induction intensity of the magnet in two orthogonal directions, and the control chip is electrically connected with the multi-axis magnetometer, obtains magnetic induction intensity, detected by the multi-axis magnetometer, of the magnet in two orthogonal directions, calculates the extension length of the lifting lens module, and finally determines the position of the lifting lens module. The electronic equipment is advantaged in that an internal structure of the electronic equipment is simplified, and the internal space of the electronic equipment is saved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to an electronic device and a method for determining the position of a lifting lens module. Background technique [0002] At present, there are many electronic devices on the market, especially full-screen devices, that use lifting cameras. This solution requires a mechanism to detect and locate whether the lifting camera is in place. The current method needs to use multiple sensors to detect and locate the camera in different states, such as the state where the camera is fully extended from the electronic device and the camera is fully retracted. The status of electronic equipment needs to be detected and positioned by different sensors to ensure the accuracy of the detection and positioning results. However, this structure needs to use multiple sensors, and the structure is relatively complicated, which not only causes a waste of space inside the electronic device, but also...
