[0021] For wireless Bluetooth traffic earphone and true wireless Bluetooth smart earphone, the battery of the earphone is generally welded by wire, assembled by upper and lower shell clamping, sealed and fixed by glue to realize waterproof sealing of the battery compartment and meet the reliability of the product in use. However, the battery of the existing earphone is not easy to replace. In the use process, if the battery needs to be replaced due to battery life or functional problems, consumers cannot quickly replace it themselves, and need to return the product to the manufacturer or find a professional maintenance department for processing, which greatly increases the maintenance cost. At the same time, it is not conducive to the recycling of scrapped batteries.

[0022] Therefore, the earphone assembly provided by the embodiments of the present application realizes the detachable connection of the cover and the body through the interference fit of the flexible sealing body of the cover and the body, so that the user can easily replace the battery and reduce the maintenance cost of the user.

[0023] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings.

[0024] As shown in Figure 1 , Figure 2 , Figure 3 The earphone assembly provided by the embodiments of the present application comprises:

[0025] The body 10 is provided with a receiving cavity and an opening communicating with the receiving cavity;

[0026] The battery unit 20 is arranged in the receiving cavity;

[0027] The cover 30 comprises a cover body 31 and a flexible sealing body 32 arranged along the circumference of the cover body 31. The flexible sealing body 32 can be radially deformed along the cover body 31 to be detachably arranged in the opening and interference-fitted with the opening;

[0028] The fixing structure detachably connects the body 10 and the cover 30.

[0029] In the technical scheme adopted in this embodiment, the storage cavity is provided by the storage body 10, and the battery unit 20 can be stored in the storage cavity. The battery unit 20 can provide power for the earphone, ensuring normal use of the earphone. The storage cavity is protected by the storage cover 30, and when the earphone assembly needs to be assembled, the storage cover 30 covers the opening of the storage cavity. At this time, the storage cover 30 can be connected to the storage body 10 through the deformation of the flexible sealing body 32 by applying an external force to the storage cover 30. When the earphone assembly needs to be disassembled, the storage cover 30 can be separated from the storage body 10 by applying an external force in the opposite direction. Moreover, the flexible sealing body 32 is in interference fit with the opening, which can ensure the sealing between the storage cover 30 and the storage body 10. In addition, the fixed structure can ensure the firm connection between the storage cover 30 and the storage body 10, and facilitate the user to disassemble and install.

[0030] Specifically, the earphone assembly comprises a storage body 10, a battery unit 20, a storage cover 30, and a fixed structure.

[0031] The material of the storage body 10 can be wear-resistant material, which has certain supporting capacity and can support the deformation of the flexible sealing body 32.

[0032] The battery unit 20 is movably arranged in the storage cavity of the storage body 10 and can be charged through a USB interface or other charging methods. It should be noted that the connection between the battery unit 20 and the electronic elements is detachable to replace the battery. The detachable connection can be plug-in or bolted.

[0033] The storage cover 30 is designed to be detachable, thereby realizing the detachability of the battery unit 20. It can be understood that the flexible sealing body 32 can be deformed, thereby facilitating the installation of the storage cover 30 on the storage body 10. Through interference fit, the storage cover 30 can be tightly fixed after installation without the need for additional fixing devices. Moreover, the elastic property of the flexible sealing body 32 also makes the storage cover 30 easily detachable when needed, facilitating the removal of the internal battery unit 20. In addition, the flexible sealing body 32 can provide a sealing effect to reduce dust, moisture or other impurities from entering the inside of the storage cavity. Through interference fit with the opening, the flexible sealing body 32 can be tightly fitted at the opening to form an effective sealing barrier. The flexible sealing body 32 can be made of wear-resistant and aging-resistant materials such as silicone or rubber to ensure performance in frequent opening and closing operations.

[0034] The fixed structure is used to realize the connection between the storage cover 30 and the storage body 10. Through the fixed structure, the connection between the storage cover 30 and the storage body 10 can be strengthened when the storage cover 30 is closed. The fixed structure can adopt threaded connection, buckle 34 connection or other detachable connection methods.

[0035] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of this utility model, the fixing structure includes a clip 14 disposed on the compartment body 10 and a buckle 34 disposed on the compartment cover 30. The buckle 34 cooperates with the clip 14 to realize the connection between the compartment body 10 and the compartment cover 30.

[0036] In this embodiment, the fixing component may further include a locking head 14 and a latch 34. In this embodiment, the latch 34 is disposed on the compartment cover 30 and is designed as a protruding portion for engaging with the locking head 14. The locking head 14 is disposed on the compartment body 10 and is designed as a groove or elastic structure, capable of tightly engaging with the latch 34 to achieve a secure connection. When the compartment cover 30 is closed, the locking head 14 connects with the latch 34, thereby restricting the movement of the compartment cover 30 and effectively reducing the risk of accidental opening during use, ensuring the sealing and stability of the receiving cavity. The latch 34 typically has a certain degree of elasticity so that it can smoothly engage with the locking head 14 during installation and remain secure during use.

[0037] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of this utility model, at least two card heads 14 are provided at intervals along the length direction of the compartment body 10, and each card head 14 is provided with a corresponding buckle 34.

[0038] In the technical solution adopted in this embodiment, by setting it up in this way, the connection between the bin body 10 and the bin cover 30 can be made more stable, reducing loosening or falling off caused by single-point force, and improving the reliability of the fixed structure.

[0039] Furthermore, refer to Figure 2 In one embodiment of the present invention, the cover 30 is provided with a screw hole 33, and the fixing structure also includes a nut embedded in the screw hole 33 and a screw post 11 provided in the body 10. The nut is detachably connected to the screw post 11 by a screw.

[0040] In the technical solution adopted in this embodiment, the fixing structure may further include a nut and a screw post 11. In this embodiment, a copper nut is embedded in the screw hole 33 of the compartment cover 30 and is integrally formed during mold injection. It is fixed to the screw post 11 of the compartment body 10 using a machine thread screw, thus ensuring the service life and reliability of consumers during repeated disassembly and assembly, and improving the stability and durability of the overall structure.

[0041] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of the present invention, the earphone assembly further includes a silicone plug 40, which is movably disposed within the screw hole 33 for filling and sealing.

[0042] In this embodiment, the soft rubber plug fills and seals the screw hole 33 after the screw is installed, seamlessly integrating with the appearance and concealing the screw while enhancing the product's aesthetics. It also improves the sealing effect, reducing the ingress of dust and moisture.

[0043] Furthermore, refer to Figure 4 In one embodiment of the present invention, the earphone assembly further includes a foolproof structure disposed in the screw hole 33 to restrict the rotation of the silicone plug 40.

[0044] In the technical solution adopted in this embodiment, the earphone assembly may also include a foolproof structure. The foolproof structure may be a special shape or groove, for example, a limiting block is provided in the threaded hole, or the threaded hole is set to a non-circular shape, to limit the rotation of the silicone plug 40 in the screw hole 33 and reduce the risk of the silicone plug 40 falling off.

[0045] Furthermore, refer to Figure 3 , Figure 4 In one embodiment of this utility model, the flexible sealing body 32 has an opening groove, which is provided corresponding to the battery unit 20. The headphone assembly also includes a reinforcing piece 50, which is embedded in the opening groove.

[0046] In this embodiment, a clearance groove is created at the contact point between the flexible seal 32 and the battery unit 20 to reduce adhesive residue and create clearance. A reinforcing sheet 50 is then embedded within the clearance groove to reduce the product's wall thickness, increase internal space, and maintain product strength, thereby allowing for the placement of a larger capacity battery. The reinforcing sheet 50 can be made of stainless steel.

[0047] Furthermore, refer to Figure 2 In one embodiment of the present invention, the headphone assembly further includes a circuit board 60, and the circuit board 60 and the battery unit 20 are connected by an electrical connection terminal.

[0048] In this embodiment, a circuit board 60 is used to output audio signals. In this example, the circuit board 60 is plugged into the battery unit 20, allowing the user to remove and replace the battery unit 20. Additionally, the circuit board 60 has a charging interface for connecting an external charger to charge the battery unit 20.

[0049] Furthermore, refer to Figure 2 In one embodiment of the present invention, the headphone assembly further includes a protective sheet 70, which is disposed between the circuit board 60 and the battery unit 20.

[0050] In this embodiment, the protective sheet 70 provides insulation and protection, while also offering structural support. In this embodiment, the protective sheet 70 can be a PET sheet, which has excellent electrical insulation properties, effectively preventing short circuits and ensuring safe circuit operation. PET sheets are typically thin and lightweight, and do not significantly increase the weight of the headphone assembly.

[0051] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of this utility model, the hardness of the cover body 31 is greater than the hardness of the flexible sealing body 32, and the cover body 31 and the flexible sealing body 32 are integrally molded by two-color injection molding; and / or,

[0052] The headphone assembly also includes a faceplate 12, which is inserted into the side wall of the housing 10; and / or,

[0053] The headphone assembly also includes an ear hook body 13, which is connected to the housing 10.

[0054] In this embodiment, the hardness of the cover body 31 is greater than that of the flexible sealing body 32, ensuring sufficient structural strength. This reduces the impact on the shape of the cover body 31 when the flexible sealing body 32 deforms under external force, facilitating its close fit with the housing 10. The integral molding of the flexible sealing body 32 and the cover body 31 reduces the likelihood of separation when the housing cover 30 is disassembled. The faceplate 12 provides additional protection against scratches or damage to the sidewalls of the housing 10. Additionally, some electronic components can be installed inside the faceplate, electrically connected to the internal circuit board 60 through holes in the sidewalls of the housing 10. The ear hook body 13 facilitates user comfort and, connected to the housing 10, ensures the stability of the earphones during use, reducing the risk of loosening or falling off.

[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
