In some embodiments, the cover body 60 and the inner shell 50 can also be connected by dispensing. Specifically, a groove can be provided on the inner shell 50 at the contact position between the inner shell 50 and the cover body 60, and the dispensing is applied in the groove, thereby realizing the stable connection between the inner shell 50 and the cover body 60. In some embodiments, a fixing method combining structural snap connection and dispensing connection is also adopted between the cover body 60 and the inner shell 50, so that the inner shell 50 and the cover body 60 are stably connected. This not only simplifies the assembly, but also improves the structural stability of the earphone 10. At the same time, the good sealing structure between the components of the earphone 10 is also beneficial to waterproof the earphone 10, and can effectively improve the service life of the earphone 10.

[0036] Continue to refer to Figure 2 and Figure 5 , in some embodiments, the radial dimension of the installation cavity 31 is larger than the radial dimension of the first opening 32, so as to facilitate placing the inner shell 50 in the installation cavity 31 during production and manufacturing, and at the same time is beneficial to the aesthetics of the earphone 10. Specifically, the outer wall of the inner shell 50 abuts against the cavity wall of the installation cavity 31, so as to make the internal structure of the earphone 10 compact and reduce unnecessary gaps between the structures of the earphone 10. The outer wall of the inner shell 50 abutting against the cavity wall of the installation cavity 31 can prevent water or dust from entering the earphone 10, thereby improving the service life of the earphone 10. The inner shell 50 can tightly press the second outer shell portion 30 against the first outer shell portion 20. Specifically, the side of the inner shell 50 close to the first outer shell portion 20 can abut against the installation wall 23 of the first outer shell portion 20, so as to realize simple and compact assembly of the earphone 10. In some embodiments, the cover body 60, the second outer shell portion 30 and the first outer shell portion 20 can form a gourd-shaped structure, wherein the cover body 60 and the second outer shell portion 30 are arranged on one side of the gourd-shaped structure, and the first outer shell portion 20 is arranged on the other side of the gourd-shaped structure.

[0037] Refer to Figures 4 to 6, one side of the inner shell 50 is provided with a button 52, and the button 52 is electrically connected to the control board 511. The second housing part 30 may be provided with a button 52 hole, and the button 52 hole may be surrounded by an annular flange. The button 52 may be configured to receive the pressing force applied by the user and trigger the switch through the button 52 hole. At this time, the pressing direction of the button 52 on the switch may be parallel to the main surface of the control board 511 to prevent the control board 511 from deforming in a direction perpendicular to its main surface. In one embodiment, a key groove 34 is formed at the position of the second housing part 30 corresponding to the button 52, and a rubber pad 340 that abuts against the button 52 is provided in the key groove 34. The rubber pad 340 seals the key groove 34 and is exposed on the surface of the second housing part 30. Correspondingly, the rubber pad 340 includes a soft rubber pad 3401 and a hard rubber pad 3402. The soft rubber pad 3401 is disposed in the key groove 34 and covers the key groove 34. In some embodiments, the key groove 34 is located on the side of the second housing part 30 facing the ear hook 40. When the user wears the earphone 10 through the ear hook 40, one side of the key groove 34 faces inward, which can improve the aesthetics of the earphone 10. At this time, the user presses the hard rubber pad 3402 to deform the soft rubber pad 3401, and under the avoidance of the key groove 34, a stroke is generated toward the inside of the installation cavity 31, and then acts on the control board 511. Specifically, the soft rubber pad 3401 may include an integrally connected middle convex part and an edge connection part. The edge connection part is used to connect with the second housing part 30, and the middle convex part is used to connect with the hard rubber pad 3402. The depth of the key groove 34 is greater than the thickness of the edge connection part and less than the thickness of the middle convex part. In some embodiments, the soft rubber pad 3401 and the hard rubber pad 3402 are bonded by glue. For example, glue can be injected into the key groove 34, on the upper surface of the soft rubber pad 3401, or into the mating gap between the hard rubber pad 3402 and the soft rubber pad 3401 in various ways. In some embodiments, a plurality of convex blocks that cooperate with the key groove 34 are formed at the bottom edge of the soft rubber pad 3401. When the soft rubber pad 3401 is hermetically consolidated at the key groove 34 by integral injection molding, through the cooperation between the key groove 34 and the convex blocks, the combination between the soft rubber pad 3401 and the second housing part 30 can be made more compact, ensuring the sealing effect of the earphone 10, thereby enhancing the waterproof effect of the earphone 10. In one embodiment, the button 52 may have two key positions, that is, two key positions are provided on the hard rubber pad 3402, and two columns are provided on the bottom surface of the hard rubber pad 3402 corresponding to each key position. Correspondingly, the soft rubber pad 3401 may be provided with two convex platforms, each key position corresponds to a pressing block, and a button 52 is respectively provided below each pressing block. In some embodiments, the number of the soft rubber pads 3401 may be set to two. The button 52 structure of the earphone 10 using double-shot injection molding can make the structure assembly of the earphone 10 simple and have a good waterproof effect.
