[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0028] The utility model embodiment provides a headset, such as Figures 1 to 7 As shown, the earphone includes a shell 1, which includes a front shell 11 and a middle shell 12. The front shell 11 and the middle shell 12 are installed together to form a sound cavity 13; a battery 2 and a battery holder 3 are arranged in the sound cavity 13, the battery holder 3 is installed on the middle shell 12, and the battery 2 is installed on the battery holder 3.

[0029] A rear pressure relief hole 121 is opened on the middle shell 12 , and a sound guide tube 31 is provided on the battery holder 3 corresponding to the rear pressure relief hole 121 . The sound guide tube 31 is connected to the rear pressure relief hole 121 , and connects the rear pressure relief hole 121 to the sound cavity 13 .

[0030] The utility model is provided with a sound guide tube 31 on the battery holder 3 corresponding to the rear pressure relief hole 121. After the battery holder 3 is installed, the sound guide tube 31 is docked with the rear pressure relief hole 121, and the sound guide tube 31 connects the rear pressure relief hole 121 to the sound cavity 13. In this way, when the middle shell 12 and the front shell 11 are installed by gluing, even if the glue overflows, due to the obstruction of the battery holder 3 and the sound guide tube 31, the glue is not easy to flow to the rear pressure relief hole 121 and block the rear pressure relief hole 121, thereby improving the convenience of assembly. In addition, since the rear pressure relief hole 121 is connected to the sound cavity 13 through the sound guide tube 31, the concern about the rear pressure relief hole 121 being blocked can be reduced when other components are arranged, which facilitates the arrangement of components in the sound cavity 13 and reduces the difficulty of the internal layout of the earphone.

[0031] Specifically, the technical solution of the present invention is particularly suitable for headphones (TWS+ANC dual-feed noise-cancelling headphones) that integrate true wireless stereo technology (TrueWireless Stereo, TWS) and active noise cancellation (Active Noise Cancelling, ANC) function.

[0032] The battery holder 3 is provided with a connecting seat 32, and a through connecting channel 321 is provided on the connecting seat 32. The sound guide tube 31 is installed on one end of the connecting channel 321 away from the rear pressure relief hole 121, and the sound guide tube 31 is connected to the rear pressure relief hole 121 through the connecting channel 321. By providing the connecting seat 32 and the through connecting channel 321, the sound guide tube 31 can be stably installed on the connecting channel 321, which facilitates the connection between the sound guide tube 31 and the rear pressure relief hole 121. This helps to ensure the stability of the connection between the sound guide tube 31 and the rear pressure relief hole 121, and ensures the effective connection of the rear pressure relief hole 121, thereby maintaining the sound quality and sound effect of the earphone.

[0033] The outer side of the connecting seat 32 is provided with a raised frame edge 322, and the raised frame edge 322 is arranged around the connecting channel 321 to form a recessed area 323, and the connecting channel 321 is located in the recessed area 323. In this solution, the raised frame edge 322 surrounds the connecting channel 321 to form the recessed area 323, which can increase the gap at one end of the connecting channel 321 close to the rear pressure relief hole 121, increase the alignment area with the rear pressure relief hole 121, and make it easy for the connecting channel 321 to align and communicate with the rear pressure relief hole 121. Specifically, the raised frame edge 322 can be rectangular or in other shapes, which are not specifically limited here.

[0034] Furthermore, a speaker bracket 4 and a speaker 5 are also provided in the sound cavity 13, a sound outlet 111 is provided at one end of the front shell 11, the speaker bracket 4 is installed on the front shell 11 near the sound outlet 111, and the speaker 5 is installed on the speaker bracket 4 and the front shell 11 near the sound outlet 111. In this solution, a speaker bracket 4 is further provided on the front shell 11, and the speaker bracket 4 can cooperate with the front shell 11 to provide a mounting position for the installation of the speaker 5, so as to facilitate the installation and fixation of the speaker 5. A step surface 1121 can be further provided on the supporting edge 112 of the front shell 11, and the edge support of the speaker 5 is fixed on the step surface 1121 and the speaker bracket 4. The speaker 5 can be further bonded to the step surface 1121 and the speaker bracket 4 by glue, and the speaker bracket 4 can also be bonded to the front shell 11 by glue. Since the provision of the speaker bracket 4 solves the problem of fixing the speaker 5 on the front shell 11, the front shell 11 can be more freely designed into a required shape or structure, thereby increasing the design space of the front shell 11. The sound produced by the speaker 5 is transmitted through the sound outlet 111 so that the user can hear the sound.

[0035] The front shell 11 is provided with a front pressure relief hole 411, and the speaker 5, the speaker bracket 4, and the front shell 11 are sealed and connected on one side of the sound outlet 111 to form a front cavity 132, and the front cavity 132 is connected to the front pressure relief hole 411. In the area of ​​the sound cavity 13 away from the front cavity 132, the battery 2 is installed on the side of the battery bracket 3 away from the speaker 5; the battery bracket 3, the speaker 5 and the middle shell 12 are sealed and connected to form a rear cavity 131 in a part of the sound cavity 13. The speaker 5, the speaker bracket 4 and the front shell 11 are sealed and connected together to form the front cavity 132, and the battery bracket 3, the battery 2, the speaker 5, and the middle shell 12 are arranged to cooperate to form an independent rear cavity 131. In this way, while ensuring the normal function of the front pressure relief hole 411 and the rear pressure relief hole 121, the space of the front cavity 132 and the rear cavity 131 are relatively small, which can save the remaining space of the sound cavity 13, and the remaining space can be used to assemble other accessories, which is conducive to the further miniaturization of the earphone. Specifically, the rear pressure relief hole 121 is connected to the rear cavity 131 through the sound guide tube 31. Specifically, the front shell 11 and the middle shell 12 are bonded by glue. When the front shell 11 and the middle shell 12 are bonded by glue, the glue is easy to overflow to the inner wall surface of the rear cavity 131. At this time, the glue may flow to the rear pressure relief hole 121 to block the rear pressure relief hole 121. After the rear pressure relief hole 121 is connected to the sound guide tube 31, it is connected to the rear cavity 131, ensuring the connection between the rear pressure relief hole 121 and the rear cavity 131. At the same time, due to the obstruction of the sound guide tube 31 and the connecting seat 32, the glue is not easy to flow to the rear pressure relief hole 121 to block the rear pressure relief hole 121.

[0036] Specifically, the speaker bracket 4 is provided with a mounting protrusion 41 embedded in the front shell 11 , and the front pressure relief hole 411 is opened on the mounting protrusion 41 , so that the front shell 11 has the front pressure relief hole 411 .

[0037] A mesh 6 is provided between the raised frame edge 322 and the rear pressure relief hole 121. The mesh 6 can prevent dust and other tiny particles from entering the interior of the earphone, thereby avoiding damage to the speaker 5 or other sensitive components. Specifically, the mesh 6 includes a tuning mesh 6, foam and adhesive that are stacked in sequence; the mesh 6 is bonded to the rear pressure relief hole 121 and / or the raised frame edge 322 by adhesive. The tuning mesh 6 can fine-tune the sound, affecting the sound quality characteristics of the earphone, so as to achieve a better listening effect.
