[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0028] The present application provides an earphone 100, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is an assembly view of part of the structure of an embodiment of the earphone of the present application, Figure 2 is an exploded view of the structure shown in Figure 1 , and Figure 3 is an assembly view of an embodiment of the earphone of the present application.

[0029] The earphone 100 comprises a first shell assembly 10, a circuit board 20 arranged in the first shell assembly 10, and a touch control assembly 30 arranged in the first shell assembly 10. The first shell assembly 10 comprises a first sub-shell 11, the first sub-shell 11 comprises two end walls 111 spaced apart and arranged opposite to each other along a first direction X, and a circumferential side wall 112 connecting the two end walls 111, the circumferential side wall 112 and the two end walls 111 cooperatively form a half-enclosed accommodating space 11a, the accommodating space 11a has an opening side located between the two end walls 111 and arranged opposite to the circumferential side wall 112, the circumferential side wall 112 is respectively provided with a first slot 113 and a second slot 114, the opening directions of the first slot 113 and the second slot 114 are respectively arranged towards the opening side of the accommodating space 11a. The circuit board 20 is inserted into the first slot 113 through the opening side, and is provided with a contact part 21. The touch control assembly 30 comprises a touch control electrode 31 and a support plate 32, the touch control electrode 31 comprises a sheet-shaped main body 311 and a spring sheet 312 connected with the sheet-shaped main body 311, the sheet-shaped main body 311 is attached to a first major surface 321 of the support plate 32, the support plate 32 is inserted into the second slot 114 through the opening side, and the spring sheet 312 elastically abuts on the contact part 21. The first sub-shell 11 can be arranged in a substantially columnar shape, and the first direction X can be the axial direction of the first sub-shell 11, i.e. the length direction.

[0030] In this application, the circuit board 20 is positioned in the first slot 113, and the sheet-like body 311 is attached to the support plate 32 and positioned in the second slot 114. This relatively simple structure achieves the positioning of the circuit board 20 and the sheet-like body 311, reducing assembly difficulty. Furthermore, the spring tab 312 connects to the sheet-like body 311 and abuts against the contact portion 21 on the circuit board 20. This achieves electrical connection between the sheet-like body 311 and the circuit board 20, and further secures the circuit board 20, ensuring reliable fixation. This simplifies the structure and saves internal space in the first sub-shell 11.

[0031] In some embodiments, the earphone 100 may specifically be a clip-on earphone, such as... Figure 3 and Figure 4 As shown, Figure 4 yes Figure 3 The diagram shows the headphones in a wearing state. The headphones 100 may also include a second housing assembly 50 and an elastic connector 60, wherein the elastic connector 60 connects the first housing assembly 10 and the second housing assembly 50.

[0032] like Figure 5 As shown, Figure 5 yes Figure 3 The exploded view of the headphones shown indicates that the headphones 100 may further include a sound-generating component 70, which may be disposed within the second housing component 50. For example... Figure 1 and Figure 2 As shown, the earphone 100 may also include a battery 40, which may be disposed within the first housing assembly 10. When the earphone 100 is in the wearing state, the second housing assembly 50 is disposed within the concha cavity, and the sound emitted by the sound-emitting assembly 70 can enter the concha cavity through the sound outlet hole opened on the second housing assembly 50. The first housing assembly 10 abuts against the back of the auricle, and the elastic connector 60 is wrapped around the periphery of the helix.

[0033] In some embodiments, the headphone 100 may also be an in-ear headphone, an ear-hook headphone, or a behind-the-ear headphone, etc. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0034] like Figure 6 As shown, Figure 6 yes Figure 3 The exploded view of part of the headphone structure shown shows that, in addition to the first sub-shell 11, the first shell assembly 10 may also include a second sub-shell 12 and a third sub-shell 13.

[0035] In some embodiments, the second sub-housing 12 is detachably connected with the first sub-housing 11, and the second sub-housing 12 is used to seal the opening side. The second sub-housing 12 is arranged on the side of the first sub-housing 11 away from the elastic connecting member 60. When the earphone 100 is in the wearing state, the second sub-housing 12 can abut against the back side of the auricle. The surface of the second sub-housing 12 can be covered with silica gel to improve the wearing comfort.

[0036] The circumferential wall 112 of the first sub-housing 11 can be provided with a mounting port 11b in communication with the accommodation space 11a, and the third sub-housing 13 is detachably connected with the first sub-housing 11 and seals the mounting port 11b. The third sub-housing 13 is further connected with the elastic connecting member 60. Specifically, the elastic connecting member 60 can include a metal member 61 and a silica gel coating layer covering the metal member 61, and the third sub-housing 13 can also be covered with a silica gel coating layer. The silica gel coating layer 62 of the metal member 61 and the third sub-housing 13 can be integrally injection molded, and the first housing assembly 10 and the elastic connecting member 60 are connected through the integrally injection molded silica gel coating layer 62.

[0037] The earphone 100 can further include a microphone 80 arranged in the third sub-housing 13 and electrically connected to the circuit board 20 through the mounting port 11b. Specifically, the first housing assembly 10 and the second housing assembly 50 can be respectively provided with a microphone, and the microphone 80 arranged in the first housing assembly 10 and the microphone arranged in the second housing assembly 50 cooperate to improve the sound receiving effect.

[0038] In some embodiments, the third sub-housing 13 can also be integrally formed with the first sub-housing 11. Since the third sub-housing 13 is provided with electronic elements such as the microphone 80, the internal structure of the third sub-housing 13 is relatively complex. The third sub-housing 13 is detachably connected with the first sub-housing 11, which is advantageous in reducing the molding difficulty compared with the scheme of integrally forming the third sub-housing 13 with the first sub-housing 11. On the other hand, when the third sub-housing 13 is integrally formed with the first sub-housing 11, the first sub-housing 11 will be covered with silica gel when the silica gel coating layer 62 is injection molded, which is not conducive to the miniaturization of the first housing assembly 10. By detachably connecting the third sub-housing 13 with the first sub-housing 11, this situation can be avoided.

[0039] Please refer to Figure 2 and Figure 7 , Figure 7 are Figure 2 the structural schematic diagram of the first sub-housing in

[0040] The first slot 113 and the second slot 114 can be arranged at intervals in the first direction X. The second slot 114 is closer to the corresponding end wall 111 than the first slot 113, so that the support plate 32 is closer to the corresponding end wall 111 than the circuit board 20.

[0042] Please refer to Figure 7 In some embodiments, the peripheral side wall 112 is further provided with a partition plate 115, which cooperates with one of the two end walls 111 to form the second slot 114, and the second main surface 322 of the support plate 32 abuts on the partition plate 115 and presses the sheet body 311 on one of the two end walls 111.

[0043] The partition plate 115 can be arranged parallel or approximately parallel to the corresponding end wall 111 and cooperates with the corresponding end wall 111 to form the second slot 114. The sheet body 311 is attached to the support plate 32 and is thus fixed in the second slot 114, thereby realizing reliable fixation of the support plate 32 and the sheet body 311 by a simple structure, which is conducive to saving the internal space of the first sub-housing 11.
