[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 2As shown, this utility model provides a novel neckband Bluetooth headset, including two sets of earphones 11 and a display module 12. Each set of earphones 11 has a mounting frame 13 at one end, providing a stable mounting base. Each set of mounting frames 13 has a mounting slot on one side, providing space for a small fan 14. A small fan 14 is installed in each of the mounting slots, generating airflow for heat dissipation. One set of mounting frames 13 also has a mounting groove on one side, used to fix the display module 12. The display module 12 is installed within the mounting groove. Both sets of small fans 14 are electrically connected to the display module 12. The display module 12 can be an OLED-12864 model, and the small fans 14 can be controlled to start and stop via the display module 12.

[0026] like Figures 3 to 4 As shown, the mounting frame 13 also has a mounting slot on one side corresponding to the mounting through slot. The mounting slot is used to install the cord winding assembly. The cord winding assembly can store the headphone cord 24. The cord winding assembly includes a rotating shaft 16, which can rotate to wind the headphone cord 24. Limiting plates 17 are provided on both sides of the rotating shaft 16. The limiting plates 17 can prevent the headphone cord 24 from deviating from the rotating shaft 16 when it is wound. A coil spring 18 is provided on one side of one set of limiting plates 17. The coil spring 18 can provide a restoring force to make the rotating shaft 16 rotate automatically.

[0027] Another set of limiting plates 17 is also provided with a limiting clip 19 on one side. The limiting clip 19 can cooperate with the limiting plate 17 to achieve locking. The limiting clip 19 is provided with multiple sets of first limiting chamfers on one side. One set of limiting plates 17 is provided with multiple sets of second limiting chamfers on one side corresponding to the first limiting chamfers. The first limiting chamfers and the second limiting chamfers are interlocked. Through this interlocking relationship, the position of the rotating shaft 16 can be fixed to prevent it from rotating on its own under the action of the coil spring 18. The locking function is achieved through the interlocking of the first limiting chamfers and the second limiting chamfers.

[0028] A coil spring 18 is sleeved on one end of a rotating shaft 16. A limiting groove is provided on one side of the rotating shaft 16. The limiting groove can fix one end of the coil spring 18. One end of the coil spring 18 is locked in the limiting groove. The mounting frame 13 is provided with multiple sets of limiting protrusions on one side of the coil spring 18. The limiting protrusions can fix the other end of the coil spring 18. The other end of the coil spring 18 is locked on one set of limiting protrusions. Compression springs 21 are sleeved on all four sets of limiting protrusions. The compression springs 21 can apply pressure to the limiting clips 19 to enhance the interlocking effect of the first limiting chamfer and the second limiting chamfer. The elastic recovery function of the coil spring 18 is achieved through the fixing of both ends and its own deformation.

[0029] A through groove is provided on one side of the mounting frame 13 corresponding to the rotating shaft 16. The through groove provides a rotation channel for the rotating shaft 16, which rotates through the through groove. A pressing plate 22 is provided at one end of the rotating shaft 16 corresponding to the limiting clip 19. Pressing the pressing plate 22 can drive the rotating shaft 16 to move, so that the first limiting chamfer and the second limiting chamfer are disengaged. A dust plug 23 is sleeved on the other end of the rotating shaft 16. The dust plug 23 can prevent dust from entering the interior of the mounting frame 13. The dust prevention function is achieved by sealing the gap between the rotating shaft 16 and the through groove by the dust plug 23.

[0030] Both sets of earphones 11 have earphone cables 24 at their bottom. One end of each of the two mounting frames 13 has a through hole corresponding to the earphone cables 24, providing a passage for the earphone cables 24 to pass through. A winding hole is provided on one side of the rotating shaft 16, allowing the earphone cables 24 to be fixed at one end of the winding hole. One end of the earphone cable 24 is wound around the rotating shaft 16 and electrically connected to the display module 12. The winding function of the cable winding assembly is achieved by winding the earphone cables 24 around the rotating shaft 16. When the earphone cables 24 are pulled, the rotating shaft 16 rotates, compressing the coil spring 18 and stopping. When the pull is stopped, the limiting plate 17 and the limiting clip 19, under the action of the compression spring 21, cooperate through the first limiting chamfer and the second limiting chamfer to lock the rotating shaft 16 and prevent the headphone cable 24 from retracting. When it is necessary to retract the headphone cable 24, press the pressing plate 22, the compression spring 21 is compressed, and the limiting plate 17 and the limiting clip 19 are disengaged. The coil spring 18 rebounds and drives the rotating shaft 16 to reverse, releasing the headphone cable 24 and realizing the automatic retraction of the headphone cable 24. In this way, the headphone cable 24 can be stored and released when the rotating shaft 16 rotates.

[0031] like Figures 1 to 2 As shown, each of the two sets of earphones 11 has an earplug 25 at one end. The earplug 25 enhances the sealing and comfort of wearing, ensuring a strong seal by fitting the ear canal. Each of the two sets of earphones 11 has an ear hook 26 on one side, which helps the earphones 11 to be worn more stably on the ear. Each of the two sets of mounting frames 13 is connected at one end by a neck strap 27, which is convenient for wearing around the neck. The outer walls of both the mounting frames 13 and the neck strap 27 are made of silicone, which has good flexibility and skin-friendliness, enhancing wearing comfort. Multiple sets of limiting holes are provided on one side of the limiting clip 19 and one side of the mounting frame 13. These limiting holes provide installation positions for the fixing shaft, and the fixing shaft passes through each of the multiple limiting holes to prevent the limiting clip 19 from rotating.

[0032] Each of the two sets of small fans 14 has a filter screen 15 on each side corresponding to the two sets of mounting slots. The filter screen 15 can filter impurities in the air and prevent impurities from entering the mounting frame 13 and affecting the normal operation of the internal components.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When in use, the neck strap 27 is worn around the neck, the ear hooks 26 are hung on the auricle, and the earplugs 25 fit into the ear canal for stable wear. The small fan 14 can be turned on via the display module 12. The airflow generated by the small fan 14 is filtered by the filter 15 and then blown toward the neck to reduce the stuffiness caused by wearing for a long time.

[0035] When the length of the headphone cable 24 needs to be adjusted, pull the headphone cable 24. The rotating shaft 16 rotates accordingly, causing the coil spring 18 to compress. After pulling stops, the limiting plate 17 and the limiting clip 19 interlock through chamfering under the action of the compression spring 21, fixing the length of the headphone cable 24. When the headphone cable 24 needs to be stored, press the pressing plate 22. The limiting clip 19 disengages from the limiting plate 17, and the coil spring 18 rebounds, causing the rotating shaft 16 to reverse, automatically winding and retracting the headphone cable 24. The dust plug 23 prevents dust from entering the device. The silicone neckband 27 and mounting frame 13 improve wearing comfort, meeting audio listening needs while enhancing convenience and comfort during use.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
