The invention sets the box body side magnetic part 13 on the bottom shell 11, sets the earphone side magnetic part 22 on the earphone box body 211, so that when the wireless earphone 20 is placed at the placing position, the wireless earphone can be aligned and fixed position accurately through the magnetic attraction of the box body side magnetic part 13 and the earphone side magnetic part 22, the single pole Hall switch 14 can only sense the magnetism of the N pole, therefore, when the single pole Hall switch 14 is positioned at the S pole side of the box body side magnetic part 13, the N pole can not be sensed, the box body power supply 17 can not be started, the N pole of the earphone side magnetic part 22 faces outwards, when the wireless earphone 20 is placed at the placing position and the N pole of the earphone side magnetic part 22 and the S pole of the box body side magnetic part 13 are attracted, the single pole Hall switch 14 can sense the N pole of the earphone side magnetic part 22, at this time, the single pole Hall switch 14 can switch the box body power supply 17 from the closing state, the cartridge power supply 17 can charge the earphone main body 21 in the on state. According to the invention, the arrangement mode of the single-pole Hall switch 14 and the box body side magnetic part 13 is set to be that the single-pole Hall switch 14 is positioned on the S pole side of the box body side magnetic part 13, so that the control of the single-pole Hall switch 14 on the box body power supply 17 is not influenced by the installation of the box body side magnetic part 13, the N pole of the earphone side magnetic part 22 faces outwards, so that when the wireless earphone 20 is placed at a placing position, the box body side magnetic part 13 can be magnetically attracted with the earphone side magnetic part 22 to realize alignment and fixation, the wireless earphone 20 is prevented from shaking, the single-pole Hall switch 14 can start the box body power supply 17, and the wireless earphone 20 is charged, therefore, the bottom shell 11 can realize the control of the single-pole Hall switch 14 without being covered by the upper cover 12, and the smooth charging process is ensured.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
