[0003] The earphone charging box has the function of storing and charging the earphones. The earphone body is placed in the charging box for charging. At present, most designers of the charging box will design and place the earphone body in order to solve the shaking of the earphone body in the charging box. It is located at the bottom of the charging box; and most charging boxes will be designed with a charging box cover. In order to solve the possible movement interference between the charging box cover and the earphone body when the charging box is opened, the earphone body will also be placed The bottom of the charging box is designed to be installed at a relatively deep position, which causes users to only be able to grasp a small part of the top of the earphone body when taking the earphones. It is relatively smooth, and the friction between the user's fingers is very small, making it difficult for the user to take the earphone body out of the charging box smoothly, which affects the user experience

[0004] In the existing charging technology, due to the small size of the TWS earphone body, wireless charging cannot be implemented on the earphone body at present. The existing TWS earphones usually need to be equipped with a charging box with both charging and storage functions. The TWS earphone has a charging contact. The charging box has a power supply spring contact pin that is in contact with the charging contact pin. Since the contact area between the charging contact pin and the power supply contact pin is usually small, in order to achieve stable charging, it is usually necessary to fix the TWS earphone in the charging box so that the charging contact pin The pins squeeze and contact each other; however, there are still some defects in the fixing method of the existing TWS earphones

The charging box is generally composed of a charging box body and a cover. The cover is assembled and fixed by the outer shell and the upper inner support. The body is assembled and fixed by the lower inner support and the outer shell. The charging box body and the cover are connected by a shaft, The hinges or hinges are hinged to each other; a positioning slot is designed between the upper inner support and the lower inner support to limit the position of the TWS earphone. Considering the convenience of consumers to take the TWS earphone, the cavity size of the positioning slot is usually slightly larger than the shape of the TWS earphone Due to the small size, the positioning groove cannot reliably define the position of the TWS earphone, and the positioning reliability is relatively poor

An opposite-sex magnet needs to be designed between the positioning groove and the TWS earphone body to assist positioning. In order to achieve reliable positioning, it is usually necessary to increase the magnetic attraction force appropriately, so as to increase the magnet adsorption area, and a large number of magnets need to be distributed; this leads to two Problem, the magnetic field formed by the magnet inside the earphone will affect the antenna effect of the earphone, affect the use of the TWS earphone and the pairing of the two earphones, and increase the later debugging work; another problem is that the magnet will take up a large space and make the earphone The size of the TWS headset becomes larger and the structure is not compact; moreover, the large-area distribution of magnets still cannot completely avoid the risk of dislocation of the TWS earphones, which affects the reliability of positioning and thus affects the reliability of charging.
