The boss 111 is used to limit the distance that the sleeve 2 moves toward the opening direction of the earphone receiving groove 11, and prevent the sleeve from being separated from the earphone receiving groove 11. The boss 111 is uniformly disposed around a circumference of the side wall of the earphone accommodating groove 11, and the height of the boss 111 in the depth direction of the earphone accommodating groove 11 should ensure that the height of the recess space formed below the boss 111 is greater than the height of the sleeve 2. The sidewall of the sleeve 2 is positioned in a recess space formed below the boss 111 and can move up and down in the recess space. The inner space of the sleeve 2 and the space of the earphone accommodating groove 11 surrounded by the boss 111 together form an accommodating space of the earphone.
Wherein, the height of the concave space formed below the boss 111 is greater than the height of the sleeve 2, so that the sleeve 2 can move up and down in the earphone accommodating groove 11. As shown in fig. 2, when the earphone is placed in the earphone accommodating groove 11 and the earphone tail 4 enters the inner space of the sleeve 2, the bottom of the earphone tail 4 presses the bottom of the sleeve 2, so that the sleeve 2 moves downward to a first relative position (as shown in fig. 2, there is a residual space between the top of the side wall of the sleeve 2 and the bottom of the boss 111), and in the first relative position, the contact 12 may extend into the sleeve 2 through the first through hole 21 on the sleeve 2, so as to be in contact connection with the charging contact 5 on the earphone tail 4, so as to realize earphone charging.
When the earphone is moved out of the earphone accommodating groove 11 and the earphone tail handle 4 is moved out of the inner space of the sleeve 2, as shown in fig. 1, the bottom of the earphone tail handle 4 no longer presses the bottom of the sleeve 2, so that the sleeve 2 moves upward to a second relative position (as shown in fig. 1, there is a remaining space between the bottom of the sidewall of the sleeve 2 and the bottom of the earphone accommodating groove 11), and in the second relative position, the contact 12 is retracted from the first through hole 21 of the sleeve 2 and is located between the sidewall of the sleeve 2 and the sidewall of the earphone accommodating groove 11.
