When the earphone is taken out, the earphone tail handle 4 moves upward, the distance between the first magnet 15 and the second magnet 41 increases, the magnetic force gradually decreases, and the sleeve 2 passes the upward elastic force of the elastic member 17 Moving upward from the first relative position to the second relative position, due to the upward movement of the sleeve 2, the contact 12 is retracted from the first through hole 15 to the side wall of the sleeve 2 and the earphone Between the side walls of the accommodating slot 11, the earphone tail handle 4 can be completely taken out without interference.

An embodiment of the present application further provides an earphone device, as shown in FIG. 3 and FIG. 4 , including the earphone charging box and an earphone;

The earphone includes: an earphone tail handle 4, the bottom of which is provided with a second magnet 41; two charging contacts 5 are arranged on the side wall of the earphone tail handle 4, and the two The charging contacts 5 are respectively located on opposite sides of the side wall of the earphone tail handle 4; when the earphone is put into the earphone accommodating slot of the earphone charging box, the second magnet 41 and the earphone accommodating slot The first magnet is used to drive the sleeve 2 to the first relative position, and the contacts of the earphone charging box are in contact with the charging contacts 5; , the sleeve 2 is in the second relative position. The bottom of the earphone tail handle 4 includes a tail plug 42, and the tail plug 42 is buckled with the earphone tail handle 4 to form an accommodating space, and the second magnet 41 is arranged in the accommodating space.

The charging contact 5 can be integrally formed with the earphone tail handle 4 by in-mold injection, and the tail plug 42 and the earphone tail handle 4 can be fixed by an adhesive such as glue. The state where the earphone tail handle 4 of the earphone is put into the earphone accommodating slot 11 of the earphone charging box is shown in FIG. 4 , and FIG. 3 is an exploded view of the earphone and the earphone charging box. The principle of charging the earphone through the earphone charging box is as follows:

After the earphone end handle 4 enters the inner space of the earphone accommodating slot 11 and the sleeve 2, the magnetic force between the first magnet 15 and the second magnet 41 at the bottom of the earphone accommodating groove 11 increases, and the earphone end handle The bottom of the sleeve 2 presses the bottom of the sleeve 2, so that the sleeve 2 moves downward from the second relative position to the first relative position, and the bottom of the sleeve 2 presses the elastic member 17, so that the The elastic member 17 is in a compressed state, and the earphone is in a balanced state. The contact 12 protrudes from the first through hole 21 and contacts the charging contact 5 on the earphone tail handle 4, and the earphone enters the charging state. When the earphone is taken out, the earphone tail handle 4 moves upward, the magnetic force of the first magnet 15 and the second magnet 41 becomes smaller, and the sleeve 2 moves upward to the second relative position by the upward elastic force of the elastic member 17, so The contact 12 is retracted from the first through hole 21 of the sleeve 2 to between the side wall of the sleeve 2 and the side wall of the earphone accommodating slot 11, and the earphone tail handle 4 can be free from interference. Take out completely.

In the embodiment of the present application, the earphones are placed vertically, and the two side walls are used for charging, which effectively increases the distance between the two charging contacts and reduces the risk of electrolytic corrosion. The earphones are placed in the earphone charging box. When charging, the contacts of the charging box automatically pop up for charging, and when the earphones are taken out, the contacts retract to avoid friction with the sidewall of the earphones and cause scratches.

It should be noted that the structure of the automatic expansion and contraction of the contacts in the present application can be applied not only to wearable devices such as TWS earphones, but also to other electronic devices with a charging function, such as mobile phones and watches.
