Abstract

The invention provides a terminal and a terminal control method. The terminal comprises a terminal shell and a telescopic mechanism which is installed in the terminal shell and can extend out of the terminal shell or retract into the terminal shell; a magnetic field detection structure and a processor; the processor is connected with the telescopic mechanism and the magnetic field detection structure. A magnetic unit and a magnetizing device are arranged on the telescopic mechanism, the magnetizing device is matched with the magnetic unit, and the magnetizing device is connected with the processor. The original magnetic field intensity of the magnetic unit can be recovered, so that the demagnetization problem of the magnetic unit can be avoided, and the detection precision of the telescopic position of the telescopic mechanism can be ensured.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a terminal and a control method for the terminal. Background technique [0002] With the full screen of terminals such as mobile phones and tablets, telescopic mechanisms such as telescopic cameras have appeared. In order to confirm whether the extension and retraction of the telescopic mechanism are in place, the design of the telescopic mechanism usually has a module for detecting the movement stroke of the telescopic mechanism. The commonly used detection scheme is to put a small magnet on the telescopic mechanism, the magnet moves with the telescopic mechanism, and use the Hall sensor to detect the change of the magnetic field strength of the magnet to judge the operating position of the magnet, and then determine the movement stroke of the telescopic mechanism. [0003] In the detection scheme using Hall sensors and magnets, since the magnets are prone to demagn...
