In this embodiment, the magnetic field sensor detects one of the magnetic field direction and magnetic field strength of the magnet 300 to distinguish wristbands 200 of different styles. It can be understood that among multiple sets of wristbands, for different sets of wristbands with similar styles, the magnetic field direction or magnetic field strength of the magnet 300 can be set to be the same, and it can also achieve a harmonious effect when matched with the same display mode of the display part; For different sets of wristbands 200 of different styles, at least one of the magnetic field direction or magnetic field strength of the magnet 300 should be set to be different for induction by the magnetic field sensor, so that the display part can switch to different display modes accordingly, thereby ensuring that the wristband is worn on the wrist. The overall style of the device can be consistent. Certainly, in other embodiments, it is also possible that the magnetic field sensor detects the magnetic field direction and the magnetic field strength of the magnet 300 at the same time. magnetic field direction, and the magnets 300 in different sets of wristbands in the same series can be set to different magnetic field strengths; corresponding to multiple series of wristbands 200, the display part has multiple series of display modes, and each series The display modes also include a plurality of display modes with similar styles, so as to correspond to different sets of wristbands in the same series one by one, so that the wristband 200 and the display modes can be matched more harmoniously.

Further, in this embodiment, different sets of wristbands 200 are configured with the magnets 300 of the same shape, and at least two sets of wristbands 200 have different magnetization directions or magnetization amounts of the magnets 300 , In order to make the magnetic field directions or magnetic field strengths different. It should be noted that different sets of wristbands 200 are configured with magnets 300 of the same shape, which means that the magnets 300 of the same shape are installed at the same position of the wristband 200 at the same installation angle.

Further, in this embodiment, after the wristband body 220 and the connecting portion 210 on which the magnet 300 is mounted are integrally formed, the magnet 300 is magnetized so that the magnet 300 has a magnetic field. It can be understood that, in this embodiment, the connecting portion 210 is integrally formed with the wristband body 220 by encapsulation, and during this process, if the ambient temperature is too high, the magnet 300 will be demagnetized. In this embodiment, after the magnet 300 and the wristband 200 are integrally formed, the magnet 300 is magnetized to avoid the above problems. Of course, in other embodiments, if the magnet 300 is not exposed to high temperature environment during the processing of the wristband 200, the magnet 300 after magnetization can also be installed on the wristband 200, and then the magnet 300 and the wristband Belt 200 is integrally formed.
