Specifically, when it is judged according to the state information that the possibility of the current user removing the external device from the charging stand is low, the magnetic attraction component is controlled to provide a greater magnetic attraction force to ensure that the external device can be fixed on the charging stand. The suction force resists external shocks such as vibrations to ensure charging efficiency. When judging from the status information that the current user is more likely to remove the external device from the charging stand, the magnetic attraction component is correspondingly controlled to reduce the magnetic attraction force so that the magnetic attraction force between the charging stand and the external device is not enough to carry the charging stand. Pulling the external device can automatically separate the charging base from the external device, or control the magnetic component to adjust the magnetic pole of the magnetic component, so that the magnetic component cooperates with the inherent magnetic pole of the external device to exert a reverse repulsive force on the external device to avoid charging The seat moves with the external equipment.

Correspondingly, when it is determined through the state information that the earphone is currently in the non-wearing state, it means that the user has taken off the earphone, removed the charging box and put the earphone into the charging box with a high probability, and then controls the magnetic attraction component to adjust the magnetic attraction strength To the second strength, to reduce the adsorption force on the charging box through the weak magnetic field, so that the user will not drag the charging stand when taking the charging box later, thereby improving the user experience and eliminating the need to manually separate the charging stand and the charging box. .

Specifically, as shown in FIG. 6, when it is judged according to the state information that the probability that the current user takes away the external device is low, the power supply part is controlled to output voltage V1, the current generated in the coil is I1, and the magnetic field strength generated by the coil is the first. Intensity B1.
