[0026] Example:

[0027] like Figures 1 to 3 , Figure 6As shown, this utility model provides a foldable neckband wireless earphone, including a left neckband post 11, a right neckband post 12, and an earphone body 13. Each of the left and right neckband posts 11 and 12 has an instrument box 14 on one side and a connector on the other side. Multiple connectors have connecting posts passing through them, allowing the left and right neckband posts 11 and 12 to be rotatably connected via the connecting posts. The right neckband post 12 has a charging port. Each of the multiple instrument boxes 14 contains an instrument connection board 15, which can be a BES2500YP connection board. Each of the multiple instrument connection boards 15 contains a battery 16. One end of each of the multiple earphone bodies 13 is connected to an instrument connection board 15. Each of the multiple instrument boxes 14 has a winding base 17, with a rotating shaft passing through it. A winding frame is fitted onto the rotating shaft, and the earphone body 13's cable is wound around the winding frame. A rotating knob is fitted onto one side of the rotating shaft.

[0028] Specifically, the left neckband 11 and right neckband 12 serve as the main support for the neckband. The folding function is achieved through the rotating connection between the connector and the connecting post, allowing for storage and space saving when not in use. The instrument box 14 integrates core electronic components, and the instrument connection plate 15 provides a stable mounting carrier for the battery 16. The battery 16 powers the headphone body 13 and various functional modules. The winding base 17, the rotating shaft, and the winding frame constitute the cable winding and unwinding system. Rotating the knob can manually drive the rotating shaft to wind and unwind the headphone cable, preventing tangled cable. The charging port provides a channel for charging the battery 16, ensuring the headphone's battery life.

[0029] A guide platform 18 is provided on one side of the winding base 17. A motor and a fixing protrusion 19 are provided on one side of the guide platform 18. A sliding groove and a limiting sliding groove are provided on the guide platform 18. A sliding block 21 is provided in the sliding groove. One side of the sliding block 21 passes through the limiting sliding groove.

[0030] Specifically, the guide table 18 provides guidance and support for the winding of the yarn, the motor provides the power source, and the fixing protrusion 19 is used to fix the position of the drive shaft; the slide groove provides a sliding track for the sliding block 21, and the limiting slide groove further restricts the movement direction of the sliding block 21 to ensure that it moves smoothly along a straight line and avoids tangling or jamming due to deviation when the yarn is wound.

[0031] A drive shaft is provided on the fixed protrusion 19, the motor shaft end is connected to the drive shaft, one end of the sliding block 21 is sleeved on the drive shaft, and a guide cylinder 22 is provided on the sliding block 21. The headphone body 13 is threaded on the guide cylinder 22.

[0032] Specifically, the motor transmits power through the connection between the shaft end and the transmission shaft, driving the sliding block 21 to move along the slide groove; the sliding block 21 drives the guide cylinder 22 to move synchronously, and the guide cylinder 22, after being fitted with the headphone cable, standardizes the cable's direction and prevents the cable from twisting and knotting. In conjunction with the movement of the sliding block 21, the cable is evenly wound on the winding frame, improving winding efficiency and cable lifespan.

[0033] The instrument box 14 is equipped with a water removal sleeve 23, which is located on one side of the guide table 18. The water removal sleeve 23 is fixedly connected to the instrument box 14 by bolts. The water removal sleeve 23 is fitted with a water-absorbing cotton sleeve, and the headphone body 13 is threaded onto the water removal sleeve 23.

[0034] Specifically, the desiccant sleeve 23 is fixed inside the instrument box 14 by bolts. The internal absorbent cotton sleeve is absorbent. When the earphone gets wet with sweat or water, the cable passes through the desiccant sleeve 23 and the absorbent cotton sleeve can quickly absorb the moisture, preventing moisture from entering the instrument box 14 and damaging electronic components (such as the battery 16 and control panel 27), thus improving the earphone's moisture resistance and durability.

[0035] An infrared light sensor 24 is provided on one side of the water removal sleeve 23, and a cover 25 is provided on one side of the infrared light sensor 24. The headphone body 13 is threaded onto the infrared light sensor 24 and the cover 25. A sealing ring 26 is provided on one side of the instrument box 14. A control panel 27 is attached to the instrument box 14. One side of the control panel 27 is in contact with the sealing ring 26 and the instrument box 14.

[0036] Specifically, an infrared light sensor 24 detects the real-time entry and exit status of the headphone cable. This infrared sensor 24 can be a 403B-S0 sensor. When the cable is pulled out of the winding frame and passes through the sensor's detection area, the sensor recognizes the cable's exit status in real time and feeds back an electrical signal to the control panel 27 (which can be an iKFW5 control panel). This signal is then transmitted to the motor, causing the guide cylinder 22 to move. When the cable retracts into the winding frame and gradually leaves the sensor's detection area, the sensor recognizes the cable's retraction status and again feeds a signal back to the control panel, which in turn transmits it to the motor, causing the guide cylinder 22 to move. This completes the full monitoring of the cable's winding and unwinding process.

[0037] like Figures 2 to 5 As shown, the instrument box 14 has slots on both sides, and each slot has a breathable membrane 28. The charging port has a charging interface 29, and the two ends of the charging interface 29 are connected to the battery 16 respectively. The control panel 27 is electrically connected to the headphone body 13.

[0038] Specifically, the slot provides installation space for the breathable diaphragm 28, which allows air circulation inside and outside the instrument box 14, dissipates the heat from the internal components in a timely manner, avoids high temperature affecting performance, and blocks dust from entering; the charging interface 29 connects to an external power source and battery 16 through the charging port to achieve charging; the control panel 27 serves as the core of operation, is electrically connected to the headphone body 13, and can adjust the volume, switch modes, etc., and transmit electrical signals to achieve audio playback.

[0039] The inner wall of the left neck post 11 and the right neck post 12 is provided with spring abutments 31. One side of the multiple sets of spring abutments 31 is connected to the instrument box 14. The left neck post 11 and the right neck post 12 are fitted with soft sleeves 32. The left neck post 11, the right neck post 12, the multiple sets of instrument boxes 14 and the soft sleeves 32 are provided with multiple sets of position adjustment holes. Two of the sets of position adjustment holes are provided with adjustment knobs.

[0040] Specifically, the spring stop 31 cushions the impact of external forces on the instrument case 14 through elastic deformation, reducing the impact of vibration on internal components; the soft sleeve 32 uses skin-friendly material to improve wearing comfort and avoid neck pressure; the position adjustment hole and adjustment knob work together to adjust the relative positions of the left neck hanging post 11, the right neck hanging post 12 and the instrument case 14 according to the user's neck size and wearing habits, so as to achieve personalized adaptation and enhance wearing stability.

[0041] The specific usage and function of this embodiment are as follows:

[0042] When using the headphones, first complete the basic wearing and adjustment: unfold the left neckband 11 and the right neckband 12, and adjust them to a comfortable position that fits the neck using the adjustment knob. The soft sleeve 32 provides cushioning when in contact with the neck. At this time, the headphone cable is in a wound state, and the infrared light sensor 24 does not detect any movement of the cable through it, indicating that it is in the initial standby mode.

[0043] Cable release and detection trigger: When headphones are needed, rotate the knob on the winding base 17 or start the motor via the control panel 27, and the winding frame will rotate to release the cable. When the cable passes through the detection area of ​​the infrared light sensor 24, the sensor recognizes the cable entry / exit signal and transmits the signal to the motor, causing the guide cylinder 22 to move; at the same time, the sliding block 21 moves along the slide groove, and the guide cylinder 22 guides the cable to smoothly pass through the desiccant sleeve 23, while the absorbent cotton sleeve simultaneously dries the surface of the cable.

[0044] Rewinding and Function Deactivation: After use, activate the rewinding function. The cable will gradually retract into the instrument box 14 as the rewinding frame rotates. When the cable completely leaves the detection area of ​​the infrared light sensor 24, the sensor detects the cable retraction signal and starts the motor to activate the guide cylinder 22.

[0045] Charging and maintenance: When charging the battery 16 through the charging port of the right neck post 12, the infrared light sensor 24 can keep the battery 16 in a low power consumption state because it does not detect the movement of the cable. Regularly clean the absorbent cotton sleeve inside the water removal sleeve 23 to ensure the dryness of the cable when it is wound up and down. At the same time, check whether there is dust on the surface of the infrared light sensor 24 to avoid detection failure.

[0046] 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.
