[0002] A sealing ring is arranged between the key and the earphone shell of the TWS earphone, for ensuring the sealing property of the earphone shell.

[0003] At present, the TWS earphone on the market adopts an O-shaped sealing ring, which is installed in the installation groove between the circumferential side wall of the key and the earphone shell. The gap between the outer end surface of the key and the outer surface of the earphone shell is exposed to the outside. In the daily use process, dirt is easily hidden in the gap on the surface. Moreover, the width of the gap is usually about 0.1 mm. If the gap is too small, it is difficult to clean the dirt, which causes a serious appearance problem. Moreover, the O-shaped sealing ring is usually made of silica gel, which relies on the compression in the installation groove to play a sealing role.

[0040] The technical solutions of the present application are further illustrated below by specific embodiments in conjunction with the drawings.

[0041] As Figures 1 to 4As shown, the present embodiment provides a sealing ring 1 for sealing the gap 10 between the shell 2 and the button 3 mounted on the shell 2, the sealing ring 1 comprises a first connecting ring 11, a flexible deformation ring 12 and a second connecting ring 13 connected in sequence from inside to outside, the first connecting ring 11 is used for connecting to the outer surface of the button 3, the second connecting ring 13 is used for connecting to the outer surface of the shell 2, and the flexible deformation ring 12 is used for covering the gap 10 between the button 3 and the shell 2.

[0042] The sealing ring 1 provided by the present embodiment, in use, the first connecting ring 11 of the sealing ring 1 is connected to the outer surface of the button 3, the second connecting ring 13 is connected to the outer surface of the shell 2, and the flexible deformation ring 12 covers the gap 10 between the button 3 and the shell 2. When the button 3 is pressed and moved, the flexible deformation ring 12 is deformed by the pulling of the button 3, allowing the button 3 to move relative to the shell 2, ensuring the normal function of the button 3; the sealing ring 1 covers the gap 10 on the outer surface of the shell 2, which not only achieves sealing, but also prevents dirt from entering the gap 10, improving the appearance. Therefore, the sealing ring 1 provided by the present embodiment improves the sealing of the shell 2 and improves the appearance of the appearance.

[0043] Specifically, as shown in Figure 1 , Figure 2 and Figure 5 , the inner side of the first connecting ring 11 is provided with a first protrusion 111, and the first protrusion 111 is connected to a first groove 311 on the outer surface of the button 3; the inner side of the second connecting ring 13 is provided with a second protrusion 131, and the second protrusion 131 is arranged on a second groove 2131 on the outer surface of the shell 2. The mutual cooperation of the first protrusion 111 and the first groove 311 plays a limiting role for the first connecting ring 11 when the flexible deformation ring 12 deforms and pulls the first connecting ring 11, thereby improving the firmness of the connection between the first connecting ring 11 and the button 3; similarly, the second protrusion 131 and the second groove 2131 cooperate with each other, and the second connecting ring 13 plays a limiting role when the flexible deformation ring 12 deforms and pulls the second connecting ring 13, thereby improving the firmness of the connection between the second connecting ring 13 and the shell 2.

[0044] Specifically, the first connecting ring 11 is bonded to the outer surface of the button 3, and the second connecting ring 13 is bonded to the outer surface of the shell 2. The bonding connection mode can not only meet the connection strength, but also will not increase the connection structure on the outer surface, ensuring the appearance. More specifically, the first protrusion 111 is bonded to the first groove 311 by glue, and the second protrusion 131 is bonded to the second groove 2131 by glue, so that the bonding area is increased, and the connection strength is further improved.

[0045] Specifically, the flexible deformation ring 12 is an arc structure protruding towards the direction away from the gap 10. The arc structure allows the flexible deformation ring 12 to have a certain range of stretch, ensuring the moving range of the button 3.

[0046] Specifically, the first connecting ring 11, the flexible deformation ring 12 and the second connecting ring 13 are all made of plastic material.

[0047] Optionally, the sealing ring 1 is made of rubber, silicone rubber, TPU or TPE, etc.

[0048] Specifically, the first connecting ring 11, the flexible deformation ring 12 and the second connecting ring 13 are integrally formed, improving the production efficiency and the connecting strength.

[0049] Specifically, as shown in Figure 1 , Figure 2 and Figure 6 , the embodiment also provides a TWS earphone, which comprises a shell 2 and a button 3 installed in a mounting hole 212 of the shell 2, and further comprises the above-mentioned sealing ring 1, the first connecting ring 11 is connected to the outer surface of the button 3, the second connecting ring 13 is connected to the outer surface of the shell 2, and the flexible deformation ring 12 is covered in the gap 10 between the button 3 and the shell 2.

[0050] Specifically, as shown in Figure 3 , the shell 2 comprises a lower shell 21 and an upper cover 22 rotatably connected to the top of the lower shell 21, the top of the lower shell 21 is provided with an earphone accommodating groove for placing the earphone 20, and the upper cover 22 is used for covering the earphone accommodating groove to cover the earphone 20. The button 3 is used for controlling the opening of the upper cover 22 or controlling the opening of the charging of the earphone 20.

The cooperation of the first protrusion 111 and the first groove 311 plays a limiting role for the first connecting ring 11 when the flexible deformation ring 12 deforms and pulls the first connecting ring 11, thereby improving the firmness of the connection between the first connecting ring 11 and the button 3; similarly, the cooperation of the second protrusion 131 and the second groove 2131 plays a limiting role for the second connecting ring 13 when the flexible deformation ring 12 deforms and pulls the second connecting ring 13, thereby improving the firmness of the connection between the second connecting ring 13 and the shell 2.

[0054] Specifically, the color of the outer surface of the sealing ring 1 is different from the colors of the outer surfaces of the shell 2 and the button 3. The different color of the outer surface of the sealing ring 1 not only improves the appearance, but also facilitates finding the position of the button 3 and facilitates operation.

In the process of being pressed inwardly, the contact head 33 first abuts against the switch 6, then pushes the switch 6 to gradually approach the contact 5, until the switch 6 contacts the contact 5, the circuit is turned on, and the execution operation controlled by the button 3 is started. After the pressing force is removed, the button 3 returns to the original position, and the switch 6 is separated from the contact 5.

[0057] Specifically, the inner wall of the shell 2 is bonded with the rear cover 4, the rear cover 4 covers the inward end of the button 3, the contact 5 and the switch 6 are connected to the rear cover 4, the rear cover 4 not only realizes the limitation of the moving range of the button 3, but also plays the role of installing the contact 5 and the switch 6.
