Of course, in other embodiments, other fool-proofing means may be used, such as changing the appearance of the headset 10.

Referring to fig. 14 and fig. 15, the following describes the insertion and removal process of the earphone 10 of the earphone assembly 1 provided in this embodiment in detail:

referring to fig. 16, when the earphone 10 needs to be inserted into the charging box 20 for charging, the earphone 10 is obliquely inserted into the accommodating cavity 210 (in the direction indicated by the arrow a in fig. 16), so that the first connector 110 is inserted into the second connector 330. At this time, the female socket tongue 331 is inserted between the plurality of charging pins 1121, so that the charging box 20 charges the earphone 10; the female socket tongue 331 is inserted between the plurality of fixing pins 1122 so that the fixing pins 1122 grip the female socket tongue 331, thereby fixing the earphone 10. Referring to fig. 17, in a state that the first connector 110 and the second connector 330 are kept in a mating state, a downward acting force is applied to the earphone 10, so that the earphone 10 rotates downward (in a direction indicated by an arrow B in fig. 17) relative to the case 200, and the second connector 330, the holder 320 and the first circuit board 310 integrally rotate together under the driving of the earphone 10, wherein the rotating shaft 322 of the holder 320 rotates relative to the rotating shaft support 233 until the earphone 10 is accommodated in the accommodating cavity 210. Referring to fig. 18, in a state that the first connector 110 is connected to the second connector 330, the second circuit board 340 transmits power through the flexible circuit board and the first circuit board 310, so as to charge the earphone 10. At this time, the cover 250 may be rotated (in the direction indicated by the arrow C in fig. 18) to close the cover 250.

When it is necessary to take out the earphone 10 from the charging case 20, the cover 250 is opened by rotating the cover 250 (the rotating direction is opposite to the direction indicated by the arrow C in fig. 18), the earphone head 120 is pulled to rotate the earphone 10 upward to a tilted state (the rotating direction is opposite to the direction indicated by the arrow B in fig. 17), and then the earphone 10 is obliquely pulled upward with a force (the force direction is opposite to the direction indicated by the arrow a in fig. 16) so that the first plug 110 and the second plug 330 are separated, thereby obliquely pulling out the earphone 10.

In summary, in the earphone assembly 1 provided in the embodiment of the present invention, the charging assembly 300 is used to charge the earphone 10 by inserting the first plug connector 110 into the charging assembly 300, and the contact and fixing effects of the earphone 10 and the charging box 20 electrically connected to each other can be enhanced, so that the magnetic attraction fixing can be performed without using a magnet, which not only ensures that the earphone 10 is not easily shaken in the charging box 20, but also saves the internal spaces of the earphone 10 and the charging box 20, reduces the material cost, and improves the assembly process. In addition, by adopting the mode of rotating the earphone 10 after inserting the earphone 10, the plugging stroke can be shortened, effective plugging can be realized more easily, and a user can conveniently confirm whether the earphone 10 is plugged in place, so that the plugging and electrical contact effects are ensured.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
