Description

Technical Field

[0001] This application relates to the field of wearable smart device technology, and more particularly to a smart ring and wearable system. Background Technology

[0002] Smart rings are advanced electronic products that have gained widespread popularity since their introduction. However, due to the lack of sufficient testing in mass production and commercialization of their hardware, manufacturing processes, and structures, numerous technical bottlenecks remain. In particular, the small size and complex layout of smart rings lead to high costs for customizing internal components and high mass production costs. For commercial and market needs, different smart ring sizes are required to accommodate different finger sizes. However, different ring sizes result in different internal component selections and layouts, further exacerbating problems such as high mass production difficulty, poor yield and efficiency, and high overall costs. Therefore, improving the hardware layout and structure of smart rings to make them suitable for different users while simultaneously reducing mass production difficulty, yield, and efficiency has become a pressing issue. Utility Model Content

[0003] The present application discloses a smart ring and wearable system that solves the problems of high mass production difficulty, poor production yield and efficiency, and high overall cost of smart rings. It makes the ring suitable for different users, reduces the difficulty of mass production process and various costs, and improves production yield and efficiency.

[0026] As an emerging wearable device, smart rings have generated a significant impact on the consumer electronics market with every step of their technological development. As a special type of wearable device, smart rings need to be worn on the user's finger. Obviously, different users have different finger sizes. If smart rings can only offer one or a few fixed sizes, it will inevitably cause users discomfort and inconvenience.

[0027] However, smart rings are lightweight, compact, and have a large number of internal electronic components that require custom modifications to fit within the limited space, resulting in high design and manufacturing costs. To provide consumers with a more comfortable wearing experience, a wide variety of ring sizes are needed, requiring different sizes of electronic components and corresponding manufacturing processes to ensure the reliability of the final product. This further increases the product's inventory, material, and manufacturing costs, placing a heavy economic burden on both consumers and manufacturers.

[0028] To address the aforementioned problems, this application proposes a smart ring. Please refer to... Figure 1 and Figure 2 The smart ring 100 may include a housing 10, a battery cell 20, and a circuit assembly 30. The housing 10 forms a receiving cavity 13 around a first axis 15. It should be understood that the first axis 15 can be understood as the central axis of the smart ring 100, and the housing 10 may have a circumferential direction 102 around the first axis 15 and a radial direction 101 perpendicular to the first axis 15.

[0029] In some embodiments, the smart ring 100 may further include an adapter component 60. The battery cell 20, circuit assembly 30, and adapter component 60 may all extend circumferentially 102 and be disposed within the receiving cavity 13. The circuit assembly 30 and the battery cell 20 are electrically connected via the adapter component 60. The circuit assembly 30 is used to load electronic components. Specifically, the circuit assembly 30 may be a rigid PCBA board, an FPC, or a "rigid-flex" board that is partly a PCBA board and partly an FPC. An FPC can also be called a flexible printed circuit. The adapter component 60 can be used to electrically connect the battery cell 20 and the circuit assembly 30. The battery cell 20, adapter component 60, and circuit assembly 30 may all be arranged around the first axis 15. Due to limitations in current electronic and electrical technologies and battery technology, components such as the battery cell 20, electrical connectors, and circuit boards are relatively large in size and thickness. By having the battery cell 20, the adapter component 60, and the circuit component 30 all arranged around the first axis 15, excessive thickness caused by stacking can be prevented, thus preventing problems such as the accommodating cavity 13 being unable to accommodate them or becoming bulky. Those skilled in the art will understand that since the adapter component 60 can be integrally formed with the circuit component 30, and the adapter component 60 itself also includes a conductive circuit structure, the adapter component 60 can be understood as part of the circuit component 30, or as two structures distinct from the circuit component 30.

[0030] It should be understood that the adapter component 60 can be a flexible cable or a flexible printed circuit, or it can be a "rigid-flex" board that is partly a PCBA board and partly an FPC. Those skilled in the art will understand that when at least a part of the adapter component 60 is a flexible body such as an FPC or flexible cable, since the circuit component 30 and the adapter component 60 can be used to carry a variety of electronic components, when set in the accommodating cavity 13, regardless of how the ring size and the size of the accommodating cavity 13 are adjusted, the circuit component 30 and the adapter component 60 can form a good fit with the accommodating cavity 13 due to their flexibility. This eliminates the need to adapt different sizes of electronic components according to different ring sizes and to adapt different process processes to ensure the reliability of the final product. This better controls the product's inventory cost, material cost, and process cost, improves production yield and production efficiency, and reduces the difficulty of mass production of the smart ring 100.

[0031] In some embodiments, circuit component 30 may include sensing module 34. Sensing module 34 may include at least one of a second light source component 342 and a first light source component 341, and at least one photoelectric sensor 343. The first light source component 341 includes at least a red light source device and an infrared light source device. The second light source component 342 includes at least a green light source device. It should be understood that because hemoglobin in the blood absorbs light, when the heart contracts, blood flow in the blood vessels increases, absorbing more light energy and resulting in reduced reflected light; the opposite is true when the heart relaxes. Therefore, by emitting light of a specific wavelength, such as green light, red light, and / or infrared light, to the skin and using photoelectric sensor 343 to detect relevant data such as reflected light and transmitted light feedback, the required physiological parameters can be calculated, thereby conveniently and non-invasively achieving real-time monitoring of physiological parameters such as heart rate, blood oxygen saturation, and vascular elasticity. For example, green light can be emitted onto the skin. Since blood volume changes periodically with the heartbeat, the light feedback from the green light will also fluctuate. This fluctuation in light feedback intensity can be extracted as a heart rate waveform. The real-time heart rate can then be calculated by determining the fluctuation frequency (e.g., the number of peaks per unit time) or the fluctuation period (e.g., the average time interval between adjacent peaks). Similarly, red and infrared light can be emitted onto the skin. Because oxyhemoglobin and deoxyhemoglobin in the blood absorb red and infrared light differently—oxyhemoglobin absorbs more infrared light and deoxyhemoglobin absorbs more red light—a preliminary value of blood oxygen saturation (SpO2) can be calculated based on the light feedback from red and infrared light, combined with the ratio of their absorption rates to different light types and a preset algorithm or model. Finally, the detection result is output through data fusion and calibration.

[0032] In some embodiments, the sensing module 34 may include a red light source, two second light source components 342, a red light sensor, and two green light sensors, wherein the second light source components 342, the red light source, and the second light source components 342 are arranged sequentially along the circumferential direction 102. Specifically, the two second light source components 342 may be arranged symmetrically with respect to the red light source. A green light sensor may be arranged on the periphery of each second light source component 342. It should be understood that through the symmetrical arrangement of the dual second light source components 342 and the photoelectric sensors 343, dynamic changes in blood flow can be captured from multiple angles, thereby providing multi-angle signal data for detection data processing and improving the robustness and reliability of biosignal detection.

[0033] In some embodiments, a light-blocking element 344 may be provided around the photoelectric sensor 343 to prevent direct reception of light emitted from a light source, rather than reflected or transmitted light from the skin. This also further prevents interference from ambient light, improving the accuracy and reliability of the detection. The light-blocking element 344 can be light-blocking foam or light-blocking rubber.

[0034] In some embodiments, the housing 10 may have a first region 51 that contacts the user's fingertip, and the sensing module 34 is disposed in the accommodating cavity 13 located in the first region 51. This sensing module 34 may be a sensing module 34 with functions such as biosignal detection. By placing the sensing module 34 with functions such as biosignal detection in the first region 51, the sensing module 34 can be positioned close to the fingertip, thereby fully utilizing the characteristics of the fingertip, such as dense capillaries and thin epidermis, to enhance the penetration of light signals and improve the accuracy of heart rate and blood oxygen detection. This ensures that the optical detection of the sensing module 34 with functions such as biosignal detection is accurate and effective when the user wears the device normally and naturally.

[0035] To accommodate different wearers, in some embodiments, the adapter component 60 may have a length adaptable to different housings 10. In some embodiments, the length of the adapter component 60 along the circumferential direction 102 ranges from 15mm to 25mm. It should be understood that this length range of the adapter component 60 can be understood as an arc length range. It should be further understood that the position of the detection device in the circuit component 30 and the overall length of the circuit component 30 need to be adjusted according to different ring sizes so that the detection device is set to the fingertip, ensuring that the overall layout of the detection device, etc., can effectively support functions such as biosignal detection. Since the adapter component 60 and / or the circuit component 30 may have flexible parts such as FPC and flexible cables, the length of the adapter component 60 and / or the circuit component 30 in the circumferential direction 102 can be adaptively adjusted according to the size of the smart ring 100, thereby effectively ensuring that the sensing module 34 can be stably set in the receiving cavity 13 of the first region 51 and aligned with the user's fingertip, ensuring the consistency of the positional layout of the sensing module for different ring sizes. Typically, but not limitingly, the length of the adapter 60 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, or any range of two values.

[0036] In some embodiments, the housing 10 may have an inner housing 11, which defines a wearing hole 111 around a first axis 15. The diameter of the wearing hole 111 ranges from 17mm to 23mm. It should be understood that since the user can wear the smart ring 100 through the wearing hole 111 of the inner housing 11, the user's skin can easily and frequently come into contact with the inner housing 11. The sensing module 34 may include a light source and a photoelectric sensor 343, and at least a portion of the sensing module 34 may be fitted into the inner housing 11. This fitted design of the inner housing 11 reduces ambient light interference and motion artifacts. Simultaneously, multiple light sources and photoelectric sensors 343 can be arranged to capture dynamic changes in blood flow from multiple angles. Furthermore, the skin-friendly and anti-slip properties of stainless steel and other metallic materials can work synergistically to ensure that the sensor maintains close contact and data reliability during long-term wear. Typically, but not limitingly, the diameter of the wear hole 111 can be 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, or any range of two values.

[0037] In some embodiments, please refer to the supplementary information. Figure 5 and Figure 6 ,like Figure 2 , Figure 5 and Figure 6As shown, a second window 114 may be provided on the inner housing 11, which may correspond to the sensor module 34. It should be understood that the second window 114 prevents the inner housing 11 from blocking the light propagation path of the "light source-human body-photoelectric sensor 343," thereby improving the stability and reliability of functions such as biosignal detection. It should be further understood that since the sensor module 34 may have multiple light sources and photoelectric sensors 343, multiple second windows 114 may be provided on the inner housing 11 corresponding to the light sources or photoelectric sensors 343.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 ,like Figure 2 and Figure 3 As shown, the adapter component 60 may have a first end 61 and a second end 62 arranged opposite each other along the circumferential direction 102. The first end 61 is electrically connected to the battery cell 20, and the second end 62 is electrically connected to the circuit assembly 30. Since both the circuit assembly 30 and the battery cell 20 are large in size and difficult to accommodate, by setting the adapter component 60 between the circuit assembly 30 and the battery cell 20, the accommodating flexibility of the internal components of the smart ring 100 and the adaptability of the internal components to different ring sizes of the smart ring 100 can be improved more effectively, thereby reducing mass production costs and improving production yield and efficiency.

[0039] Specifically, at least a portion of the structure between the first end 61 and the second end 62 of the adapter component 60 can be bent or folded along the circumferential direction 102. It should be understood that at least a portion of the adapter component 60 can be bent to form a wave-like or serrated folded structure. By adjusting the overall extension through the wave-like / serrated folded structure, it can both adapt to smart rings 100 with different finger sizes and release mechanical stress during wear, avoiding bending fatigue fracture.

[0040] In some embodiments, the length of the adapter component 60 may range from 15mm to 25mm. The adapter component 60 may also include an FPC with laser-etched lines or pre-cut markings. It should be understood that, to achieve the cutting function, the cutable FPC can use a thinner, more flexible substrate, such as a polyimide (PI) film, wherein the laser-etched lines and pre-cut markings further facilitate adaptation cutting by manufacturers or users. Furthermore, since the length can reach 15mm-25mm, it can be cut or bent to fit smart rings 100 of different sizes.

[0041] In some embodiments, the smart ring 100 may further include a coil assembly 40, which is at least used for energy transmission; wherein the coil assembly 40 is directly or indirectly connected to the circuit assembly 30. It should be understood that users may experience sweaty palms during exercise. The coil assembly 40 can be completely sealed within the ring's receiving cavity 13. For the smart ring 100, the coil assembly 40 with energy transmission function enables functions such as wireless charging, preventing the charging / discharging interface from being exposed to sweat, moisture, or other environments, and even preventing other electronic components from being corroded by liquid intrusion. This effectively improves the reliability and safety of the smart ring 100, ensuring stable and reliable touch, interaction, communication, charging / discharging, and other functions. Specifically, the coil assembly 40 may include a wireless charging coil, at least a portion of which is embedded or attached to the adapter assembly 60. The wireless charging coil is electrically connected to the battery cell 20 through the adapter assembly 60. Specifically, the housing 10 has an inner housing 11 defining a wearing hole 111 around a first axis 15, and the coil assembly 40 is disposed in the inner housing 11. This design allows the charging area to be concealed from the outer casing 12, giving the ring more design flexibility and a more stylish and attractive appearance.

[0042] In some embodiments, please refer to the supplementary information. Figure 5 and Figure 6 ,like Figure 2 , Figure 5 and Figure 6 As shown, the inner housing 11 may have a first window 113, and the coil assembly 40 is disposed on the side of the accommodating cavity 13 near the inner housing 11 and exposed to the first window 113. It should be understood that since the coil assembly 40 may include coils such as wireless charging coils for energy transmission, when the inner ring is made of metal, the first window 113 can be opened in the inner housing 11 to prevent the energy transmission path from being blocked by the metal material, and to prevent eddy currents and shielding effects during energy transmission. When the coil assembly 40 includes coils such as NFC coils for signal communication, if the inner ring is made of metal, the first window 113 also needs to be opened in the inner housing 11 to prevent the signal communication path from being blocked by the metal material, to prevent signal shielding problems, and to improve the stability and reliability of the smart ring 100's interaction and transmission.

[0043] In some embodiments, at least a portion of the coil assembly 40 overlaps the battery cell 20 along the radial direction 101 of the housing 10. By overlapping at least a portion of the coil assembly 40 with the battery cell 20 along the radial direction 101 of the housing 10, the relatively thin structure of the coil assembly 40 itself can be utilized to improve the space utilization efficiency of the accommodating cavity 13, making the smart ring 100 more compact, lightweight, and suitable for wearing. Furthermore, by overlapping at least a portion of the coil assembly 40 with the battery cell 20 along the radial direction 101 of the housing 10, the battery cell 20 can be used to provide additional mechanical structural strength to the thin and fragile coil assembly 40, ensuring the morphological stability and reliability of the coil assembly 40 and guaranteeing the efficiency of energy and signal transmission.

[0044] In some embodiments, at least a portion of the coil assembly 40 may be disposed adjacent to the circuit assembly 30 along the circumferential direction 102. By disposing at least a portion of the coil assembly 40 adjacent to the circuit assembly 30 along the circumferential direction 102, the distance between the coil assembly 40 and the circuit assembly 30 can be reduced, thereby reducing the interference that the electrical signal between the coil assembly 40 and the circuit assembly 30 may receive during transmission and ensuring that the electrical signal is stable and reliable.

[0045] In some embodiments, the coil assembly 40 can also be used for signal transmission, the signals transmitted by the coil assembly 40 including at least one of charging information of the battery cell 20 or tag information of the smart ring 100. For example, the coil assembly 40 may include an active NFC coil or a passive NFC coil, and the above functions can be achieved by the active NFC coil or the passive NFC coil.

[0046] In some embodiments, please refer to Figure 4 ,like Figure 2 and Figure 4 As shown, the adapter component 60 can be an FPC, and at least a portion of the coil assembly 40 can be embedded in its first end 61. It should be understood that since the coil assembly 40 itself is relatively soft and has low structural strength, embedding at least a portion of the coil assembly 40 in the circuit connection board 33 or the adapter component 60 can effectively protect the internal structure and layout of the coil assembly 40, provide additional mechanical structural strength, and facilitate a stable and reliable connection between the coil assembly 40 and the battery cell 20. For example, the coil assembly 40 may include a wireless charging coil, and the circuit connection board 33 may include an FPC, in which the wireless charging coil can be embedded. It should be understood that when the coil assembly 40, such as the wireless charging coil, performs energy transfer tasks, certain current fluctuations will occur due to the corresponding current transfer. Embedding the wireless charging coil in the FPC and shortening the connection distance between the wireless charging coil and the battery cell 20 can prevent parasitic capacitance and inductance problems caused by current fluctuations over a wider range.

[0047] In some embodiments, please refer to the supplementary information. Figure 3 ,like Figures 2 to 4 As shown, the second end 62 of the adapter component 60 can be provided with welding positions adapted to different housing lengths 10. By setting welding positions adapted to different housing lengths 10, the flexibility and length advantages of the adapter component 60 can be better utilized to solve the mass production adaptation problem when the housing 10 has different ring numbers, simplifying the mass production process and reducing mass production costs. For example, in the process, different preset lengths of the adapter component 60 can be obtained according to the ring number requirements, and then the battery cell 20 or circuit assembly 30 can be welded to different welding positions according to the preset length. Finally, the adapter component 60, circuit assembly 30 and battery cell 20 are placed in the receiving cavity 13. Unused FPCs can also be cut off according to actual needs to further save internal space in the receiving cavity 13.

[0048] In some embodiments, the first end 61 of the adapter component 60 can be soldered to the circuit component 30 via a solder pad or a connector. The connector may include any suitable component such as a socket or a connecting wire. Similarly, the second end 62 can be soldered to the battery cell 20 via a solder pad or a connector. Using connectors for electrical connection simplifies the assembly process, promotes modular production, facilitates mass production, reduces process costs, provides higher connection strength, and improves product reliability. Solder pad soldering reduces the number of different types of raw materials, lowers material costs, and eliminates the need to adapt and equip different connectors for different models of circuit components 30 and battery cells 20.

[0049] In some embodiments, the adapter assembly 60 may include an FPC with a recessed area 63. The smart ring 100 may also include a wireless communication module 35, which includes an antenna disposed within the receiving cavity 13 corresponding to the recessed area 63. Specifically, the housing 10 may have a first region 51, a second region 52, and a third region 53. The first region 51 may be the region that contacts the user's fingertip, the second region 52 may be the region disposed radially 101 of the housing 10 opposite to the first region 51, and the third region 53 may be the region disposed between the first region 51 and the second region 52. The circuit assembly 30 also includes the wireless communication module 35, and the adapter assembly 60 has a recessed area 63 so that the wireless communication module 35 is disposed within the receiving cavity 13 of the third region 53 near the second region 52. It should be understood that antennas are often large and require no electronic components to obstruct them, making it difficult to house them within the compact housing 10. By creating a clearance area 63 on the FPC, space can be reserved for the placement of antenna devices, and obstruction and signal interference caused by electronic devices installed on the FPC can be reduced. It should be further understood that, due to the clearance area 63, the wireless communication module 35 can be placed within the accommodating cavity 13 on the side of the third region 53 closest to the second region 52, thereby ensuring that the wireless communication module 35 is prevented from being obstructed by fingers or other body parts under different hand gestures, thus ensuring stable antenna signal strength.

[0050] Specifically, the housing 10 may have a first region 51 that contacts the user's fingertip, a second region 52 disposed opposite to the first region 51 along the radial direction 101 of the housing 10, a third region 53 disposed between the first region 51 and the second region 52, and a fourth region 54 disposed opposite to the third region 53 along the radial direction 101 of the housing 10. Those skilled in the art will understand that the division of regions is for the convenience of reading and understanding the text and drawings of this technical solution, and should not be mechanically considered to include only a specific angular range on the circumferential direction 102 of the smart ring 100.

[0051] In some embodiments, the housing 10 includes an inner housing 11 and an outer housing 12. The inner housing 11 defines a wearing opening 111, and the inner housing 11 and the outer housing 12 together define a receiving cavity 13. The circuit assembly 30 also includes a touch module 31, which includes a touchpad 311 for recognizing touch signals. The touchpad 311 is disposed adjacent to the outer housing 12 along the radial direction 101 of the housing 10. Specifically, the touchpad 311 can be attached to or embedded in the outer housing 12. Touch interaction can be realized through the touchpad 311, avoiding the occupation and impact of button switches on the designable space of the outer surface of the smart ring 100. Furthermore, the touchpad can also support various gesture operations such as swiping, further improving the interactive experience.

[0052] In some embodiments, the housing 10 has an indicator 55 on the side opposite to the receiving cavity 13, and the indicator 55 is disposed in the second region 52 and / or the fourth region 54. Since the smart ring 100 is ring-shaped, without the indicator 55, it would be difficult for users to identify structural areas such as the "finger pad area" for accurate wearing and functional assurance. Furthermore, it would be inconvenient to adjust the specific position of the smart ring 100 after wearing it, especially in dark environments where users would have difficulty finding the touch area for interactive functions and the finger pad area for health monitoring. By placing the indicator 55 in the second region 52 and / or the fourth region 54, users can accurately complete tasks such as wearing, adjusting, touching, interacting, and detecting the smart ring 100 without observing it, further improving the functional stability, interactive reliability, and wearing comfort of the smart ring 100.

[0053] Furthermore, the indicator portion 55 may include at least one of a protrusion or a recess. A specific logo may also be provided on the indicator portion 55 itself or between multiple indicator portions 55. It should be understood that the indicator portion 55 may be a structural protrusion or recess, or it may be a specific mark or texture. Those skilled in the art will understand that marks and textures themselves can also be expressed in the form of protrusions or recesses, and therefore also fall within the scope of protection of this application.

[0054] In some embodiments, a passive NFC coil may be disposed in the second region 52 of the accommodating cavity 13, or the housing 12 may have a hole space in which the passive NFC coil may be disposed. Specifically, the hole space may be disposed in the ceramic layer of the housing 12. The passive NFC coil may be disposed corresponding to the indicator 55 or the logo. Since the passive NFC coil is disposed corresponding to the indicator 55 or the logo, it facilitates users in aligning with external devices more easily when using the NFC function, thereby achieving a stable and reliable communication connection.

[0055] In some embodiments, the smart ring 100 may further include a support member 131, which is disposed between any two of the inner housing 11, the touch module 31, and the battery cell 20, so that the touch panel 311 is close to the outer housing 12. Specifically, the support member 131 may include support foam, support gel, etc. It should be understood that different users can fit different ring sizes, and the slope of the housing 10 and the size of its accommodating cavity 13 are also different. If a traditional fixing method is used, it is necessary to adapt different parts, or even customize some components, to achieve a sufficiently strong iron and fixation. Moreover, for wearable devices such as the smart ring 100, the compact structure itself determines the difficulty of standardization, and it is difficult to set mass-produced, standardized fasteners in the narrow accommodating cavity 13. Therefore, by employing elastic support components 131 such as support foam and support colloid, flexible assembly can be achieved. This not only reduces the difficulty of mass production assembly processes and significantly improves production efficiency and yield, but also works synergistically with the relative positional relationship between the aforementioned touch module 31 and battery cell 20 to form a support force transmission path, ensuring the stable fit of the touch panel 311 to the housing 12 and guaranteeing the stability and reliability of touch interaction. It should be understood that the fit between the touch component and the housing 10 is often not tight enough, and there is relative movement between the battery cell 20 and the housing 10, resulting in insufficient stability. The support foam is used to indirectly adjust the fit between the touch component and the housing 10 and to strengthen the relative fixation strength between the battery cell 20 and the housing 10.

[0056] In some embodiments, at least a portion of the housing 10 may be configured as a metal portion 112. It should be understood that the metal portion 112 may be an area on the housing 10 that is in contact with the human body for a long time during wear, or it may form the inner ring of the housing 10, or it may be a ring. The metal portion 112 only needs to be able to make an electrical connection with the human body under certain circumstances, and no specific limitation is made here.

[0057] In some embodiments, the battery cell 20 and the circuit assembly 30 may be disposed in the accommodating cavity 13, wherein the circuit assembly 30 is electrically connected to the battery cell 20. Specifically, the circuit assembly 30 may include a touch module 31, a control module 32, and a grounding portion, with the touch module 31 and the control module 32 being electrically connected. The touch module 31, the control module 32, and the metal portion 112 are directly or indirectly electrically connected to the grounding portion. It should be understood that the touch module 31 may be a self-capacitive or mutual-capacitive touch module 31. When the user wears the smart ring 100 on their finger, static electricity from the human body will be conducted to the housing 10, or static charge will be generated on the housing 10 due to skin friction, thereby causing potential fluctuations in the housing 10, which will interfere with the capacitive sensing signal and have a significant impact on the accuracy, precision, and smoothness of human-computer interaction. By directly or indirectly connecting the touch module 31, the control module 32, and the metal part 112 to the grounding part, the electrostatic charge can be released to the grounding part in a timely manner through the metal part 112, preventing the electrostatic charge from accumulating in the housing 10 for a long time and changing the potential of the housing 10.

[0058] Those skilled in the art will understand that the specific shape, layout, material, and other related schemes of the grounding part can be adjusted according to the actual circuit wiring needs and various factors such as board type and material. The grounding part is set on the circuit assembly 30 and can form a direct or indirect electrical connection with the touch module 31, the control module 32, and the metal part 112. No specific restrictions are imposed here.

[0059] In some embodiments, the metal part 112 and the grounding part can be connected by an electrical connector 14. The electrical connector 14 can be conductive foam, wire, or FPC. For example, at least a portion of the circuit connection board 33 can be an FPC, and the housing 10 is directly soldered to the FPC, thereby electrically connecting the metal part 112 and the grounding part through the FPC. Alternatively, the metal part 112 and the grounding part can be electrically connected by a single section of FPC. It should be understood that by connecting with conductive foam 14, it is not necessary to solder the stainless steel inner housing 11 to the FPC, reducing the number of processes, reducing mass production difficulty, saving process costs, improving production yield and efficiency, and the fit of the circuit connection board 33 relative to the housing 10 can be adjusted by the conductive foam 14, further improving structural reliability and stability.

[0060] This application also proposes a mobile communication system, which includes a mobile communication device and a smart ring 100 as described in any embodiment of this application. The mobile communication device is capable of communicating with the smart ring 100. It should be understood that the mobile communication device may include mobile devices with communication functions such as wireless headphones, tablets, mobile phones, and game consoles, as well as wearable devices with communication functions such as smart glasses and smart bracelets. The communication connection between the mobile device and the smart ring 100 can be one-to-one, many-to-one, one-to-many, or many-to-many, and no specific limitations are imposed here. The mobile communication device can also be used in conjunction with the smart ring 100 to form a wearable system.

[0061] This application also provides a wearable system, which may include a wearable device and a smart ring 100 as described in any embodiment of this application. The wearable device is communicatively connected to the smart ring 100. It should be understood that, due to the compact and small size of wearable devices such as smart glasses, it is difficult to achieve convenient and rich interaction within the existing size or weight. Adding interactive modules such as a touchpad 311 to smart glasses would require excessive user movements, causing discomfort and inconvenience. Simple voice interaction would expose user privacy and make it difficult to achieve functions such as mobile payment and password input. Therefore, the smart ring 100 can be used as an interaction medium with smart glasses. For example, touch interaction with the smart ring 100 can enable the transmission and reception of control signals between the smart ring and the smart glasses, thereby achieving convenient, elegant, and private human-computer interaction.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
