DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0029] The present invention provides a headset, such as Figures 1 to 3 As shown, the earphone includes a shell 1, a speaker module 2, a fixing bracket 3 and a battery 4; an installation cavity 11 is formed in the shell 1, and the speaker module 2 is installed in the installation cavity 11, and the installation cavity 11 is divided into a front sound cavity 111 and a rear sound cavity 112; the front sound cavity 111 is provided with a sound outlet 12 connected to the outside world, and the rear sound cavity 112 is provided with a pressure relief hole 13 connected to the outside world.

[0030] The rear sound cavity 112 includes a first inner space side 112a and a second inner space side 112b opposite to the first inner space side 112a. In the direction from the front sound cavity 111 to the rear sound cavity 112, the height of the second inner space side 112b is greater than that of the first inner space side 112a.

[0031] The fixed bracket 3 is installed in the rear sound cavity 112. The fixed bracket 3 has an inclined mounting surface 31. The inclined mounting surface 31 is located on the side of the first inner space side 112a and is inclined toward the direction close to the speaker module 2. The side of the second inner space side 112b is inclined toward the direction away from the speaker module 2.

[0032] The earphones of the present invention are provided with a fixing bracket 3, through which the battery 4 inside is mounted in the rear sound cavity 112 separated by the speaker module 2. The fixing bracket 3 has an inclined mounting surface 31 adapted to the spatial shape of the first inner space side 112a and the second inner space side 112b of the rear sound cavity 112. The side located on the first inner space side 112a is inclined toward the speaker module 2, and the side located on the second inner space side 112b is inclined away from the speaker module 2. The battery 4 is then mounted on the inclined mounting surface 31. This allows the battery 4 to be installed as closely as possible to the spatial shape of the rear sound cavity 112, improving the space utilization of the battery 4 installation, reducing the difficulty of installing the battery 4, and reducing the difficulty of arranging other components after saving space.

[0033] Specifically, if Figure 4 As shown, the earphone package is installed on the main control circuit board 5 of the earphone outer rod 8 and the FPC circuit board 6 is installed in the shell 1. The main control circuit board 5 is electrically connected to the battery 4 and the speaker module 2 through the FPC circuit board 6. The specific connection between them can be set up using conventional technology and will not be repeated here. The speaker module 2 can be fixed in the installation cavity 11 by glue, and the front sound cavity 111 and the rear sound cavity 112 are separated by glue sealing. The sound generated by the speaker module 2 is transmitted through the sound outlet 12, and the pressure relief hole 13 is used to relieve pressure on the rear sound cavity 112, maintain the air pressure balance of the installation cavity 11, and improve the sound quality. The pressure relief hole 13 is opened on the shell 1 at the second inner space side 112b.

[0034] Specifically, if Figure 5 As shown, support edges 32 are provided on opposite sides of the inclined mounting surface 31. These edges are mounted on the inner wall of the housing 1. The fixing bracket 3 is mounted on the inner wall of the housing 1 via the support edges 32, enabling convenient and stable installation. A limiter 321 is provided on the support edge 32. The limiter 321 limits the side position of the battery 4 mounted on the fixing bracket 3, ensuring a stable installation of the battery 4 on the fixing bracket 3. The battery 4 can be further bonded to the fixing bracket 3 using glue or other means.

[0035] like Figures 5 to 7 As shown, the inner wall surface of the housing 1 is provided with a plurality of spaced support ribs 14 corresponding to the support edges 32. The support edges 32 are supported on the support ribs 14. The provision of the support ribs 14 provides support for the support edges 32, resulting in a simple structure and stable support. Specifically, two support ribs 14 are provided corresponding to each support edge 32. Of course, the fixing bracket 3 can be further bonded to the inner wall of the housing 1 using glue.

[0036] The end of the support edge 32 is provided with a retaining portion 322. A retaining slot 15 is provided on the inner wall of the housing 1 corresponding to the retaining portion 322. The retaining portion 322 retains within the retaining slot 15. In this embodiment, the cooperation between the retaining portion 322 and the retaining slot 15 further enables pre-positioning and post-installation positioning of the fixed bracket 3, ensuring convenient and secure installation of the fixed bracket 3. Furthermore, the cooperation between the support rib 14 and the support edge 32, as well as the cooperation between the retaining portion 322 and the retaining slot 15, further ensures a secure and stable installation of the fixed bracket 3.

[0037] Furthermore, a snap-fitting portion 33 is provided on the side edge of the fixing bracket 3 located on the first inner space side 112a. A snap-fitting piece 16 is provided on the inner wall of the housing 1 corresponding to the snap-fitting portion 33. The snap-fitting piece 16 has a snap-fitting interface 161 formed on the snap-fitting piece 16, and the snap-fitting portion 33 is snap-fitted into the snap-fitting interface 161. This solution further provides a snap-fitting portion 33 on the side edge of the fixing bracket 3 located on the first inner space side 112a. The snap-fitting portion 33 snaps into the snap-fitting interface 161 on the snap-fitting piece 16, and cooperates with the supporting rib 14, the supporting edge 32, the snap-fitting portion 322, and the snap-fitting slot 15 to achieve a secure overall installation of the fixing bracket 3.

[0038] More specifically, the clamping portion 33 is provided with a limiting protrusion 331, which abuts the side of the clamping piece 16 facing the fixed bracket 3. When the fixed bracket 3 is installed, when the clamping portion 33 is inserted into the clamping interface 161, the limiting protrusion 331 can abut the side of the clamping piece 16 facing the fixed bracket 3, indicating that the clamping portion 33 is properly installed, achieving convenient and accurate assembly of the clamping portion 33.

[0039] Furthermore, the inclined mounting surface 31 is provided with a support surface 311 and a hollow area 312. The support surface 311 serves as a supporting portion to support the battery 4, while the hollow area 312 can improve heat dissipation of the battery 4.

[0040] The present invention also discloses an earphone kit, comprising an earphone charging compartment and the aforementioned earphones, which can be stored and charged in the compartment. This earphone kit has the same structure and benefits as the earphones in the aforementioned embodiments. The structure and benefits of the earphones have been described in detail in the aforementioned embodiments and will not be repeated here.

[0041] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
