[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Reference Figures 1 to 4 As shown, a Bluetooth headset structure includes two Bluetooth headset bodies 1 and a neckband 2. The neckband 2 includes a neckband arc rod 21 and connecting parts 22 disposed at both ends of the neckband arc rod 21. At least one of the connecting parts 22 is provided with a battery. Both connecting parts 22 are connected to a charging interface 23. The charging interface 23 is connected to the battery of the connecting part 22 through a wire 24. The two Bluetooth headset bodies 1 are detachably connected to the two charging interfaces 23 respectively. When the Bluetooth headset body 1 is inserted into the charging interface 23, the battery charges the Bluetooth headset body 1.

[0026] The two Bluetooth earphone bodies 1 are the left and right ear Bluetooth earphones, respectively. The Bluetooth earphone bodies 1 can be in-ear Bluetooth earphones or semi-in-ear Bluetooth earphones.

[0027] Users can use the Bluetooth headset 1 alone, or assemble it with the neckband 2 to create a neckband-style Bluetooth headset. This combines the advantages of in-ear or semi-in-ear Bluetooth headsets with neckband-style Bluetooth headsets, overcoming the limitations of traditional headphone designs and meeting user needs in different scenarios. For example, the Bluetooth headset 1 can be used alone during daily work. When traveling or exercising, the Bluetooth headset 1 and neckband 2 can be assembled to create a neckband-style Bluetooth headset, thereby increasing the battery life of the Bluetooth headset 1 and effectively reducing the risk of loss through physical connection.

[0028] Reference Figure 4 As shown, specifically, the charging interface 23 has a recess 231, and a charging pin 232 is located at the bottom of the recess 231. The Bluetooth headset body 1 has a charging port for the charging pin 232 to be inserted. When charging is required, the Bluetooth headset body 1 is inserted into the recess 231, and the charging port is aligned with the charging pin 232.

[0029] The charging port 23 is magnetically connected to the Bluetooth headset body 1 via a first magnetic attraction structure. This first magnetic attraction structure prevents the Bluetooth headset body 1 from accidentally falling out when inserted into the charging port 23.

[0030] Specifically, the first magnetic attraction structure can be achieved by setting opposite magnetic poles on the charging port 23 and the Bluetooth headset body 1 to attract each other.

[0031] In another embodiment, the first magnetic structure can be provided with a magnet in either the charging port 23 or the Bluetooth headset body 1, and the other component can be provided with a magnetically conductive material to achieve mutual attraction between the two.

[0032] Reference Figure 4 As shown, the outer circumferential surface of the Bluetooth headset body 1 is provided with an annular groove 11, and the charging interface 23 is provided with a plurality of spring pins 25 embedded in the annular groove 11. Through the cooperation of the spring pins 25 and the annular groove 11, the spring pins 25 pop out under the action of elasticity and lock into the annular groove 11 to form a mechanical lock, ensuring a stable connection and preventing loosening due to vibration or external force. This further prevents the Bluetooth headset body 1 from detaching from the charging interface 23 and avoids accidental drop of the Bluetooth headset body 1.

[0033] Reference Figure 2 and Figure 3 As shown, both connecting portions 22 have positioning slots 221 on their outer sides for embedding the charging interface 23. When the user does not need to use the Bluetooth headset body 1, embedding the charging interface 23 into the positioning slots 221 can prevent the Bluetooth headset body 1 from shaking significantly due to the redundant length of the wire 24 during movement, thus avoiding the risk of the Bluetooth headset body 1 detaching from the charging interface 23 due to inertia, without affecting the charging status of the Bluetooth headset body 1.

[0034] As one embodiment, refer to Figure 3 As shown, the connecting part 22 is provided with a plurality of deformation hooks 222 arranged along the length direction of the positioning groove 221. The deformation hooks 222 are used to fix the charging interface 23 in the positioning groove 221, thereby preventing the charging interface 23 from falling out of the positioning groove 221.

[0035] In another embodiment, the positioning groove 221 and the charging interface 23 are magnetically connected by a second magnetic attraction structure, thereby preventing the charging interface 23 from detaching from the positioning groove 221.

[0036] The second magnetic attraction structure can be specifically designed by setting opposite magnetic poles in the charging interface 23 and the positioning slot 221 to attract each other.

[0037] In another embodiment, the second magnetic attraction structure can be provided with a magnet in either the charging interface 23 or the positioning slot 221, and a magnetically conductive material in the other component, so that the two attract each other.

[0038] The connecting part 22 includes a contact switch protruding from the positioning groove 221. A buzzer is provided in the connecting part 22. When the charging interface 23 is disengaged from the contact switch, the buzzer emits a prompt sound for several seconds.

[0039] Specifically, when the charging interface 23 is inserted into the positioning slot 221, the contact switch is pressed, and the contact switch sends a signal to the chip. The chip then records the connection status of the charging interface 23, shuts down the buzzer drive circuit, and enters a low-power standby mode to reduce system power consumption. When the charging interface 23 is removed from the positioning slot 221, the contact switch resets. After detecting the signal change, the chip immediately exits the standby mode and controls the buzzer to emit a beeping sound for several seconds to remind the user that the headphone charging interface 23 has been removed from the positioning slot 221. This prevents the Bluetooth headset body 1 from being removed from the positioning slot 221 along with the charging interface 23. It also avoids the risk that the Bluetooth headset body 1 may be removed from the charging interface 23 due to inertia during movement, caused by the redundant length of the wire 24.

[0040] Both connecting portions 22 are equipped with the rechargeable battery, and both connecting portions 22 have a display screen on their outer side for displaying the battery level. The two batteries charge the two Bluetooth headset bodies 1 respectively. The dual-battery design increases the number of charging cycles, and the dual-screen design can display the battery levels of the left and right batteries separately, avoiding the problem of one side not being able to charge due to uneven power levels.

[0041] The neck-hanging arc rod 21 is made of nickel-titanium shape memory alloy. Users can bend the neck-hanging arc rod 21 into a suitable shape according to their own wearing needs, so as to accurately fit the curvature of different users' necks.

[0042] When the battery in the connection part 22 charges the Bluetooth headset body 1, the internal power storage module of the Bluetooth headset body 1 does not work. Instead, the battery powers the power consumption module in the Bluetooth headset body 1 and charges the power storage module at the same time. This avoids the power storage module being used while it is being charged, thus improving the lifespan of the power storage module. The circuit design of this part can refer to the circuit planning design of desktop lamps and desktop fans, which is existing technology and will not be described in detail here.
