It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] In existing technologies, wearable devices transmit audio via wireless connectivity, but this presents limitations in terms of functional integration. Some solutions attempt to combine a camera with headphones, but the limited internal space of headphones leads to complex structural designs. When users need real-time video calls or action photography, existing integration solutions often require additional support structures, increasing the size of the headphones and affecting wearing comfort. Furthermore, the chaotic internal wiring can cause signal interference; the complex structure and difficult wiring also contribute to the overall size of the headphones.

[0044] Please see Figure 1 This utility model provides a wearable device 100, including: an earphone body 10 and a shooting component 20;

[0045] The earphone body 10 has a shaft 12 on it, which extends towards the end near the shooting component 20. The shaft 12 has a connection channel 121, and a chip 11 is disposed inside the earphone body 10.

[0046] The shooting assembly 20 includes a housing 21 and a camera 22. The housing 21 has a base plate 211 and a through hole 212. The shaft 12 extends into the housing 21 through the through hole 212.

[0047] The ribbon cable 30 passes through the connection channel 121 to connect the camera 22 and the chip 11.

[0048] A shaft 12 is provided on the earphone body 10, extending away from the earphone body 10. The shaft 12 has a connecting channel 121. The camera assembly includes a housing 21 and a camera 22. The housing 21 has a base plate 211 with a through hole 212. The diameter of the through hole 212 is larger than the diameter of the shaft 12, allowing the shaft 12 to pass through the through hole 212 and extend into the camera assembly 20. This allows the camera assembly 20 to rotate on the shaft 12. A ribbon cable 30 is provided in the connecting channel 121. Within 21, the chip 11 located inside the earphone body 10 can be electrically connected to the camera 22 located in the shooting assembly 20 via the ribbon cable 30; by connecting the shooting assembly 20 and the earphone body 10 through the connection channel 121, the ribbon cable 30 can be completely hidden inside the earphone structure, avoiding the ribbon cable 30 being exposed or prone to breakage or tangling due to complex wiring methods, thus improving the connection stability between the chip 11 and the circuit board 60, and increasing production efficiency and product lifespan.

[0049] Please see Figure 2 and Figure 3 In some embodiments, the base plate 211 is provided with an extension 213 protruding into the housing 21 along the through hole 212, the shaft 12 is provided with a first groove 122, a first rubber ring 123 is provided in the first groove 122, and the first rubber ring 123 abuts against the extension 213.

[0050] Understandably, the shaft 12 is provided with a first groove 122, and a first rubber ring 123 is provided in the first groove 122. The base plate 211 is provided with an extension 213 protruding into the housing 21 along the outer periphery of the through hole 212. The first rubber ring 123 abuts against the extension 213, that is, the first rubber ring 123 and the extension 213 are interference fit. The first rubber ring 123 can play a sealing role between the shaft 12 and the extension 213, and can also provide damping force for the shooting component 20 when it rotates around the shaft 12, so that the shooting component 20 can be limited after rotating to the preset position, and avoid the shooting component 20 from moving again when shaking, which would affect the accurate positioning of the shooting component 20.

[0051] Optionally, the first rubber ring 123 and the second rubber ring 124 mentioned above are both made of silicone or rubber, which can achieve multi-dimensional positioning while ensuring rotational flexibility, and solve the wear problem caused by rigid connection.

[0052] Please see Figure 2 and Figure 3 In some embodiments, the base plate 211 is further provided with a limiting part 214 around the outer periphery of the through hole 212, and the shaft 12 is fitted with a second rubber ring 124, which abuts against the limiting part 214.

[0053] Understandably, a second rubber ring 124 is also fitted at the bottom of the shaft 12. The second rubber ring 124 is fitted at the bottom of the shaft 12 and abuts against the abutment part 152, that is, the second rubber ring 124 and the abutment part 152 are interference fit. When the shooting component 20 rotates around the shaft 12, the second rubber ring 124 can also provide friction for the shooting component 20, so that after the shooting component 20 rotates to the preset position, it is affected by the friction of the second rubber ring 124 to prevent the shooting component 20 from shifting, so as to make the positioning of the shooting component 20 more accurate.

[0054] Please see Figures 3 to 6 In some embodiments, it also includes: a fastener 40;

[0055] The shaft 12 is provided with a second groove 125, which is located at the end of the shaft 12 away from the headphone body 10, and the fixing member 40 cooperates with the second groove 125.

[0056] Understandably, a second groove 125 is provided at the end of the shaft 12 away from the headphone body 10. The fixing member 40 is snapped into the second groove 125. The fixing member 40 is a ring-shaped member with an opening 42. The snapping method constrains the shooting component 20 from the shaft 12. At the same time, the snapping member also facilitates the assembly of the shooting component 20 and the shaft 12. That is, when assembling, the fixing member 40 is installed into the second groove 125 to fix the shooting component 20 on the shaft 12, so that the shaft 12 will not be dislodged from the through hole 212 due to external force during rotation, or the shooting component 20 will be displaced during rotation.

[0057] Please see Figure 6 In some embodiments, the fastener 40 includes a guide portion 41;

[0058] The fastener 40 has an opening 42, and guide portions 41 are provided on both sides of the opening 42. The guide portions 41 are inclined to the opening 42 of the guide portions 41.

[0059] Understandably, the fastener 40 has an opening 42 for engaging the fastener 40 into the second groove 125. The fastener 40 is elastic, and when the fastener 40 is installed on the shaft 12, the fastener 40 can deform to enlarge the opening 42, thereby allowing the fastener 40 to engage into the second groove 125 of the shaft 12, so that the fastener 40 and the shaft 12 can cooperate.

[0060] Understandably, the guide portions 41 provided on both sides of the opening 42 are outwardly expanding inclined guide structures, which can be set as inclined surfaces or arc surfaces to achieve guidance. The inclined surfaces or arc surfaces allow the fixing member 40 to be inserted into the shaft 12 more smoothly, so as to fix the shooting component 20. This avoids assembly difficulties caused by misalignment, thereby simplifying the assembly process and improving structural reliability. The fixing member forms a symmetrical guiding structure through the guide portions 41 on both sides of the opening 42, ensuring that the shaft 12 is stable in position within the fixing member 40.

[0061] Please see Figure 6 In some embodiments, it further includes: a plurality of limiting members 50;

[0062] The limiting member 50 is disposed on the top of the fixing member 40 along the axial direction of the fixing member 40, and a plurality of the limiting members 50 are disposed at intervals on the top of the fixing member 40.

[0063] Understandably, multiple limiting members 50 are provided on the top of the fixing member 40. The setting direction of the multiple limiting members 50 is parallel to the axial direction of the fixing member 40, and the multiple limiting members 50 are spaced apart. They can also be mirrored or randomly set, or they can be spaced apart around the circumference of the fixing member 40. The limiting members 50 are used to constrain the position of the circuit board 60. The multiple limiting members 50 all protrude from the side wall of the top of the fixing member 40. The circuit board 60 is mounted on the limiting members 50, which facilitates the fixing and installation of the circuit board 60.

[0064] Please see Figure 6 and Figure 7 In some embodiments, it also includes: a circuit board 60;

[0065] The circuit board 60 is provided with a limiting hole 61, and the limiting member 50 passes through the limiting hole 61 to restrict the circuit board 60.

[0066] Understandably, the shooting component 20 also includes a circuit board 60 and a camera 22. The circuit board 60 is located on top of the fixing member 40. The circuit board 60 is provided with a limiting hole 61. The diameter of the limiting hole 61 is adapted to the diameter of the limiting member 50 so that the limiting member 50 can be inserted into the limiting hole 61, so that the circuit board 60 and the limiting member 50 can be connected and engaged. In this way, the limiting member 50 can limit the circuit board 60 in the horizontal direction. This not only makes the integration of the wearable device 100 higher, but also facilitates the disassembly and maintenance of the circuit board 60.

[0067] Understandably, circuit board 60 can also integrate a wireless communication module. This module enables communication between the mobile phone and camera 22. The communication module can support Bluetooth 5.0 or Wi-Fi to ensure low-latency and highly stable data transmission. Users can view images and videos captured by the camera module 300 in real time via a mobile app and perform remote control.
