Further, wireless earphone box that charges still includes the switch lid detection device who detects switch lid state, and when switch lid detection device detected lid 2 and storehouse body 1 not lock, processing unit control rechargeable battery did not discharge, only when wireless earphone in the storehouse body 1 and lid 2 lock on the storehouse body 1, processing unit could control rechargeable battery and discharge. Of course, the function can also be used for charging one earphone monomer independently.

It should be noted that, the switch cover detection device can also use a hall sensor and a magnet, and the working principle of the switch cover detection device is the same as the detection principle of detecting whether the wireless earphone is placed in the bin body 1, which is not described herein again. Of course, the switch cover detection device can also select a micro switch (for example, judge through detecting whether the bin body 1 and the cover body 2 are in contact) or a contact switch (for example, judge through detecting whether the bin body 1 and the cover body 2 are in contact), which is not limited to this.

The utility model discloses a theory of operation does: after the detection module detects that the wireless earphone is completely placed in the bin body 1, the charging contact 30 of the charging module 3 extends out of the side wall and is electrically connected with the charging contact 203 on the wireless earphone for charging.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments.
