Description

Technical Field

[0001] This utility model relates to a neckband earphone. Background Technology

[0002] Neckband headphones are a common type of headphone that reduces pressure on the neck and ears by hanging around the neck; they are suitable for wearing for extended periods.

[0003] Currently, neckband headphones commonly use Bluetooth to wirelessly connect to mobile phones. However, these headphones require an independent power source for operation. Existing technology offers two types of neckband headphones: rechargeable and replaceable batteries. Battery replacement typically involves a mounting cavity containing the battery, protected by a cover. This method lacks a sealed design, compromising waterproofing. In rainy weather or during exercise with heavy sweating, the headphones are directly exposed to the elements and skin, allowing rainwater and sweat to enter the battery mounting cavity, potentially causing damage or even rendering the headphones unusable. Existing patent document "CN219919134U" further supports this. In a neckband Bluetooth headset with a replaceable battery, a rotating cover and a mounting window on the cover are included. Rotating the cover aligns the mounting window with the battery mounting position, opening the headset; disaligning the window closes it. While this installation method provides protection when closed, the rotating cover lacks a sealing design, and a gap exists between the cover and the battery mounting bracket, compromising its waterproof performance. Improving the waterproof performance of the battery mounting is a crucial issue that needs to be addressed in the design of neckband headsets. Utility Model Content

[0024] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0025] like Figure 1-3 As shown, a neckband earphone includes an earphone body 1; the earphone body 1 has a neckband hose 2 and an earplug 3, a battery case 4 is fixedly connected to one end of the neckband hose 2, the other end of the neckband hose 2 is connected to a control unit, and the control unit has buttons for operation, wherein the control unit is equipped with a Bluetooth module for connecting to a mobile phone, and the earplug 3 is used to insert into the ear.

[0026] The battery housing 4 is disposed on the earphone body 1, and the battery housing 4 has a mounting cavity 403, in which a battery 6 is embedded; a telescopic protective sleeve 5 is wrapped around the battery housing 4 to form protection, and one end of the telescopic protective sleeve 5 is fixedly connected to one end of the battery housing 4; a sealing connector is disposed at one end of the telescopic protective sleeve 5, and the telescopic protective sleeve 5 is detachably connected to one end of the battery housing 4 through the sealing connector, and a seal is formed in the connected state.

[0027] In practical implementation, through the design of the telescopic protective sleeve 5 and the sealing connector, one end of the telescopic protective sleeve 5 is directly fixed to the battery shell 4 to form a permanent seal, while the other end is detachably installed to the battery shell 4 through the sealing connector. In the installed state, it forms a seal, ensuring the sealing and protection effect of the battery 6 installation position, improving waterproof performance, and making it difficult for external rainwater and sweat to enter. Furthermore, when replacing the battery 6, it can be removed from the battery shell 4 through the sealing connector, and the telescopic characteristics of the telescopic protective sleeve 5 can be used to retract it, exposing the battery 6 installation position and enabling battery 6 replacement.

[0028] One end of the battery case 4 extends outward to form a first outer edge 401, and the other end of the battery case 4 extends outward to form a second outer edge 402. The end of the telescopic protective sleeve 5 is fixedly sleeved with the first outer edge 401; thus, a closed system is formed by fixing and without gaps at the connection.

[0029] The sealing connector includes a telescopic sleeve and a second sealing gasket 11; the second sealing gasket 11 is fixedly installed at the second outer edge 402, one end of the telescopic sleeve is connected to one end of the telescopic protective sleeve 5, and the other end of the telescopic sleeve is threadedly connected to the second outer edge 402.

[0030] The telescopic sleeve is threadedly connected to the second outer edge 402 to achieve detachable installation.

[0031] The telescopic sleeve includes an inner sleeve 8 and an outer sleeve 9. One end of the inner sleeve 8 extends into the outer sleeve 9, and the other end of the inner sleeve 8 is fixedly sleeved with one end of the telescopic protective sleeve 5. The end of the inner sleeve 8 located inside the outer sleeve 9 extends outward to form a third outer edge 801, which mates with the inner ring of the outer sleeve 9. One end of the outer sleeve 9 extends inward to form an inner edge 901, which mates with the outer ring of the inner sleeve 8. The other end of the outer sleeve 9 is pressed against the second sealing gasket 11. A first sealing gasket 10 is provided between the third outer edge 801 and the inner edge 901, and the first sealing gasket 10 is fixedly connected to the third outer edge 801.

[0032] The sealing between the inner sleeve 8 and the outer sleeve 9 is achieved by the first sealing gasket 10.

[0033] The second outer edge 402 is provided with an external thread 4021; the inner ring of the outer sleeve 9 is provided with an internal thread 902. The external thread 4021 and the internal thread 902 are threadedly connected.

[0034] The telescopic protective sleeve 5 is internally equipped with a helical spring 7. One end of the helical spring 7 is fixedly connected to the first outer edge 401, and the other end of the helical spring 7 is fixedly connected to the inner ring of the inner sleeve 8. By adding the helical spring 7, it is possible to ensure that when the sealing connector is connected to the second outer edge 402, the helical spring 7 is stretched to generate a tensile elastic force, thereby clamping the first sealing gasket 10 between the third outer edge 801 of the inner sleeve 8 and the inner edge 901 of the outer cylinder, ensuring a seal at that position.

[0035] The telescopic protective sleeve 5 is a rubber corrugated hose; the use of rubber corrugated hose achieves the telescopic characteristic, while there are no gaps around it. One end is permanently fixed and sealed, and the other end can be detached and installed. When installed, it forms a seal, ensuring the sealing effect of the battery installation position.

[0036] Instructions for use: When using the entire neckband headphones, insert battery 6 into the mounting cavity 403, as follows: Figure 2 As shown, the telescopic protective sleeve 5 and the sealing connector form a sealed protection for the battery 6 installation position. One end of the telescopic protective sleeve 5 is directly fixed to the battery shell 4 to form a permanent seal. The sealing connector on the other end is threaded to the battery shell 4 through the external thread 4021 and the internal thread 902, which can be disassembled. In the connected state, the outer sleeve 9 presses the second sealing gasket 11, and the helical spring 7 is in a stretched state, providing elastic tension to the inner sleeve 8, so that the third outer edge 801 of the inner sleeve 8 and the inner edge 901 of the outer cylinder clamp the first sealing gasket 10, thereby achieving a seal and ensuring waterproof performance.

[0037] When replacing battery 6, rotate the outer sleeve 9 to separate the external thread 4021 from the internal thread 902. The outer sleeve 9 and the inner sleeve 8 are not fixed together and are both circular. Therefore, the rotation of the outer sleeve 9 is not affected by the inner sleeve 8. Then, slowly loosen the outer sleeve 9. The elastic force of the coil spring 7 causes the telescopic protective sleeve 5 to retract, exposing the mounting cavity 403. Take out the battery 6 from the mounting cavity 403 and replace it with a new battery 6. Then, pull the outer sleeve 9 close to the external thread 4021. When pulling, the outer sleeve 9 drives the third outer edge 801 through the inner edge 901, causing the inner sleeve 8 to move together and stretch the coil spring 7. Then, rotate the outer sleeve 9 to connect the external thread 4021 with the internal thread 902. The outer sleeve 9 presses the second sealing gasket 11, and the third outer edge 801 of the inner sleeve 8 and the inner edge 901 of the outer cylinder clamp the first sealing gasket 10.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
