[0032] In this specification and the embodiments, any processing of personal information will be carried out only under the premise of legality (such as obtaining the consent of the personal information subject, or being necessary for the performance of a contract), and will only be carried out within the scope stipulated or agreed upon. A user's refusal to process personal information other than that necessary for basic functions will not affect the user's use of basic functions.

[0033] As mentioned earlier, smart rings, as a niche market within wearable devices, have gradually gained favor with tech giants and consumers in recent years. They typically connect wirelessly to devices such as smartphones to monitor human health and push notifications to users via their phones.

[0034] However, most existing ring technologies are limited to basic indication or monitoring functions, failing to fully utilize their ease of wear and compact design to enhance the user experience. Currently, rings on the market typically lack audio output capabilities, requiring users to rely on other devices for information transmission or audio playback.

[0035] Embodiments of this disclosure provide a ring to solve, or at least partially solve, the aforementioned problems or other potential problems present in conventional rings. Figure 1 A cross-sectional view of a ring according to an embodiment of the present disclosure is shown. Figure 2 It shows Figure 1 An enlarged view of part A in the middle, and Figure 3 An exploded view of the ring is shown.

[0036] like Figures 1 to 3 As shown, the ring according to an embodiment of the present disclosure generally includes a housing 101, a protrusion 102, and a speaker assembly 103. The housing 101 is configured to have a ring shape suitable for a user to wear on their finger. Various sizes of housing 101 can be provided to accommodate differences in finger size. The protrusion 102 protrudes outward from a predetermined position on the housing 101 to form a speaker cavity at that predetermined position. The protrusion 102 has a sound outlet 1021.

[0037] A loudspeaker assembly 103 is disposed within a loudspeaker cavity and includes a sound-generating component 1031 and a cavity shell 1033 adapted to form a resonant cavity 1032. The sound-generating component 1031 is disposed within the cavity shell 1033 and communicates with the resonant cavity 1032 via airflow. The resonant cavity 1032 can increase the air pressure change during the movement of the diaphragm of the sound-generating component 1031, thereby enhancing the sound output at specific frequencies. When the diaphragm vibrates, it causes the air within the cavity to resonate, which can enhance the output of the sound-generating component 1031 at certain frequencies, especially low frequencies. Furthermore, the shape and internal structure of the resonant cavity 1032 can affect the propagation of sound waves. Sound wave reflection within the resonant cavity 1032 can enhance sound waves at certain frequencies while attenuating or eliminating sound waves at other frequencies, thereby improving the frequency response of the loudspeaker.

[0038] The sound-generating component 1031 is positioned corresponding to the sound outlet 1021 so that the sound emitted by the sound-generating component 1031 can be transmitted through the sound outlet 1021. This correspondence means that the diaphragm of the sound-generating component 1031 is at least partially aligned with the sound outlet 1021, thereby facilitating sound output. The sound outlet 1021 can be an array of multiple small holes arranged according to a predetermined rule. Parameters such as the shape of the array, the shape of the small holes, and their spacing can be adjusted as needed, and are not limited herein.

[0039] By incorporating a speaker assembly 103 with a vibrating cavity 1032, a small ring worn on a user's finger can output audio. In this way, users can transmit information or play audio without relying on external devices, thus overcoming the shortcomings of traditional rings in audio interaction and improving the user experience.

[0040] In some embodiments, the second length L2 of the sound-generating component 1031 in the tangential direction of the ring is in the range of 8 mm to 10 mm, for example, 9 mm; the second width W2 in the axial direction is in the range of 5 mm to 7 mm, for example, 6 mm; and the second height H2 in the radial direction is in the range of 1 mm to 3 mm, for example, 2 mm or 3 mm. Figure 1 and Figure 3 As shown. Using this size of sound-generating component 1031 allows the ring to be smaller and easier to wear.

[0041] In some embodiments, a waterproof and acoustically permeable membrane may be provided in the speaker cavity between the sound outlet 1021 and the sound-generating component 1031. The waterproof and acoustically permeable membrane can effectively prevent water from entering the speaker cavity and causing damage to the sound-generating component 1031, and can also allow sound to be transmitted from inside the sound-generating component 1031.

[0042] from Figure 3 As can be seen from the example, the housing 101 has an outer peripheral wall, an inner peripheral wall, and axially opposed sidewalls located between the inner and outer peripheral walls. When worn on a user's finger, the inner peripheral wall contacts the user's finger, and the outer peripheral wall is located at the radially outermost edge of the ring. In some embodiments, the sidewalls may have a generally planar structure, and optionally, they may have an arcuate or bent transition at the junction with the inner and outer peripheral walls. In some embodiments, the sidewalls of the housing 101 may also have an outwardly convex arcuate shape, thereby making the housing 101 more rounded overall.

[0043] In some embodiments, the shape of housing 101 described above can be achieved using a structure including an outer shell 1011 and an inner shell 1012. Specifically, in some embodiments, housing 101 may include an outer shell 1011 and an inner shell 1012 that are radially coupled together. The outer shell 1011 includes a protrusion 102 formed or disposed thereon. For example, in some embodiments, the protrusion 102 may be integrally formed with the outer shell 1011. In some alternative embodiments, the protrusion 102 may also be coupled to other portions of the outer shell 1011 in a suitable manner. The outer shell 1011 may have a complete annulus and a U-shaped cross-section in the radial direction. The inner shell 1012 is disposed radially inside the outer shell 1011 and is hermetically coupled to the outer shell 1011 to form the speaker cavity mentioned above and at least one functional chamber 1013. As will be described in detail later, at least one functional chamber 1013 is used to house functional components, which may include, but are not limited to, at least one of a microphone unit 1051, a communication unit, an indicator unit 1052, a button unit 1053, a battery unit 1054, a vibrator unit, and a sensor unit. In some embodiments, similar to the outer shell 1011, the inner shell 1012 may also have a complete annulus and a U-shaped cross-section in the radial direction, thereby forming a speaker cavity and at least one functional chamber 1013.

[0044] In the housing 101 having an outer shell 1011 and an inner shell 1012, the radial outer wall of the outer shell 1011, as mentioned above, forms the outer peripheral wall of the housing 101, the inner peripheral wall of the housing 101 is formed by the radial inner wall of the inner shell 1012, and the sidewalls are formed jointly by the outer shell 1011 and the inner shell 1012. In some alternative embodiments, the housing 101 may also be formed by two or more other structures, which will not be described in detail below.

[0045] In some embodiments, when the ring is worn, the protrusion 102 is located on the outer side of the ring, away from the back of the finger, thereby facilitating sound output to the outside. In some embodiments, the protrusion 102 may include a platform portion 1022 and a connecting portion 1023. The platform portion 1022 is arranged away from the inner shell 1012 and includes the sound outlet 1021 mentioned above. That is, the platform portion 1022 may be part of the outer peripheral wall mentioned above. The sound cavity shell 1033 is arranged inside the platform portion 1022. The connecting portion 1023 is arranged to connect the platform portion 1022 to other parts of the outer shell 1011, such as... Figure 1 and Figure 3As shown, the portion of the connecting part 1023 located between the axial end walls of the housing 101 (i.e., the portion belonging to the outer peripheral wall) extends along the tangential direction of the annular shape of the housing 101. In some embodiments, the platform portion 1022 is connected to the connecting part 1023 via a transition portion, which may include at least one of a chamfer or a fillet. In this way, the structure of the protrusion 102 can be made more ergonomic, making the ring more aesthetically pleasing and comfortable for the user to wear.

[0046] In some embodiments, the first length L1 of the platform portion 1022 in the tangential direction of the ring is in the range of 9mm to 11mm, for example, 10mm; the first width W1 in the axial direction is in the range of 7mm to 9mm, for example, 8mm; and the first height H1 of the platform portion 1022 from the inner circumferential surface of the ring is in the range of 2.5mm to 4mm, for example, 3mm, 3.4mm, 3.5mm, etc. Figure 1 and Figure 3 As shown. The use of this size platform section 1022 allows the ring to be smaller and easier to wear.

[0047] Of course, it should be understood that, such as Figure 1 and Figure 3 The structure of the protrusion 102 shown is merely illustrative and is not intended to limit the scope of this disclosure. The protrusion 102 may have any other suitable structure, provided that the speaker assembly 103 can be reasonably accommodated. For example, in some alternative embodiments, the protrusion 102 may also protrude along one or both sides of the ring in the axial direction.

[0048] In some embodiments, the inner shell 1012 can be formed by potting and curing. Specifically, the outer shell 1011 can be first placed in an appropriate position in a mold, and the various units of the functional components can be placed according to predetermined positions. After the various units of the functional components are placed in the appropriate positions of the outer shell 1011, the positions of the various units can be fixed by appropriate jigs, and liquid glue can be poured into the mold. After the glue cures, appropriate grinding or trimming can be performed to form a sealed chamber and the inner shell 1012 simultaneously. In this way, the ring can be made easier to manufacture and has better sealing performance, improving the sealing and waterproof performance of the ring.

[0049] In some embodiments, the vibrating cavity 1032 can be designed as a rear cavity, that is, the vibrating cavity 1032 is arranged on the side of the sound-generating component 1031 away from the sound outlet 1021. The rear cavity design makes efficient use of the limited space of the ring. Furthermore, as the rear cavity volume increases, the low-frequency response of the speaker is improved. In addition, the volume of the vibrating cavity can also be reasonably set according to the needs of the sound-generating component 1031, for example, within 0.2 mm. 3 ~0.5mm3 Unequal or any other suitable size, for example, it could be 0.2mm. 3 .

[0050] The following will combine Figure 1 and Figure 3 This will illustrate the specific structure of the acoustic cavity shell 1033. For example... Figure 1 and Figure 3 As shown, the acoustic cavity housing 1033 includes a top portion and a bottom portion 1035. The top portion is disposed on the side of the acoustic cavity housing 1033 adjacent to the sound outlet 1021. The top portion has a top opening 1034 aligned with the sound outlet 1021. A sound-emitting component 1031 is disposed inside the top portion. The bottom portion 1035 is disposed on the side of the acoustic cavity housing 1033 away from the sound outlet 1021 and is configured to have an arcuate shape to conform to the annular shape of the housing 101.

[0051] In some embodiments, a sealing ring may be provided between the top opening 1034 and the sound-generating component 1031, thereby effectively preventing the risk of foreign objects or moisture entering the sound cavity shell 1033. In this way, the sealing ring can improve the overall waterproof capability and shock resistance of the ring.

[0052] In some embodiments, the acoustic cavity shell 1033 further includes a circumferential wall. The circumferential wall is formed circumferentially between the top portion and the bottom portion 1035 to form a resonant cavity 1032 together with the top portion and the bottom portion 1035. For example... Figure 3 As shown, the circumferential wall may include a pair of planar walls arranged opposite each other in the axial direction of the ring and a pair of protruding walls located between the ends of the pair of planar walls. The shape of each pair of protruding walls is convex. For example, in some embodiments, the shape of the protruding walls includes at least one of an arcuate shape or a bent shape. Figure 1 and Figure 3 The diagram shows that the outer protrusion has a bent shape. The portion of the outer protrusion adjacent to the connecting portion 1023 can follow the shape of the connecting portion 1023.

[0053] On the one hand, the use of a speaker assembly 103 with a sound cavity shell 1033 facilitates the manufacturing of the entire ring. During manufacturing, the various units of the functional components, including the speaker assembly 103, are placed according to predetermined positions. After fixing the positions of each unit with a suitable jig, liquid colloid is poured into a mold to form the inner shell 1012. This manufacturing process is simple and quick and does not affect the interior of the speaker assembly 103. On the other hand, the use of an outwardly convex wall optimizes the space occupied by the sound cavity shell 1033 and effectively avoids the generation of standing waves.

[0054] It should be understood that, Figure 1 and Figure 3 The structure of the acoustic cavity shell 1033 shown is merely illustrative and is not intended to limit the scope of this disclosure. Any other suitable structure of the acoustic cavity shell 1033 is possible as long as it can accommodate the sound-generating component 1031 and provide an effective vibration cavity 1032. For example, in some alternative embodiments, the outer protruding walls of the acoustic cavity shell 1033 may also be formed in an arc shape. In some embodiments, the acoustic cavity shell 1033 may be made of a metallic material to reduce wall thickness while maintaining structural strength. The various parts of the acoustic cavity shell 1033 may be manufactured by welding, stamping, or a combination of both.

[0055] The functional components mentioned above can be connected to the sound-generating component 1031 via cables or flexible printed circuit boards (FPCs). In some embodiments, appropriate locations on the outer protrusions of the acoustic cavity housing 1033 may have perforations or slots for cables or flexible printed circuit boards to pass through, thereby facilitating the electrical connection of the sound-generating component 1031 and other functional components via cables or flexible printed circuit boards.

[0056] The communication unit in the functional components can establish a data transmission link with an external device and transmit data through appropriate means. These appropriate means may include, but are not limited to, Bluetooth, Wi-Fi, cellular networks, or Near Field Communication (NFC). Considering the low-power transmission performance of Bluetooth, the ring in the embodiments of this disclosure can connect to an external device via Bluetooth.

[0057] In some embodiments, the speaker assembly 103 can be electrically connected to the communication unit and used to play sound data received via the communication unit. In this way, users can conveniently hear sound through the ring without headphones or other sound output devices, thereby further improving the user experience. In some embodiments, the ring is connected to a mobile phone via Bluetooth, and voice messages played by the voice assistant on the mobile phone can be transmitted to the ring via Bluetooth and played through the speaker assembly 103 on the ring.

[0058] The microphone unit 1051 can be configured to receive external sound from the pickup hole of the housing 1011 and is electrically connected to the communication unit to transmit the external sound to an external device. By equipping the microphone unit 1051, in certain usage scenarios, such as when it is inconvenient for the user to take out an external device like a mobile phone, the user can use the microphone unit 1051 on the ring to input voice information or voice commands to the external device, conveniently controlling the external device to perform various functions or input information. In this way, the user experience when using the ring and external devices can be significantly improved.

[0059] In some embodiments, the functional chamber 1013 may include at least a microphone chamber and a communication chamber to accommodate the microphone unit 1051 and the communication unit, respectively. In some embodiments, the microphone chamber and the communication chamber may be independent and sealed chambers, and the electrical connection between the microphone unit 1051 and the communication unit is established only by appropriate means. The pickup hole mentioned above is arranged on the outer wall corresponding to the microphone chamber to facilitate the introduction of sound into the microphone chamber from the outside. Keeping the microphone chamber and other parts of the chamber, including the communication chamber, independent and sealed can improve the sound pickup performance of the microphone unit 1051 and improve the overall waterproof capability of the ring. Of course, in some alternative embodiments, the microphone chamber and the communication chamber may also be chambers that are interconnected in terms of airflow, and the embodiments of this disclosure are not limited to this.

[0060] In some embodiments, to facilitate user operation of the ring, the ring may also include a button unit 1053. The button unit 1053 may include a button, which may include at least one of a mechanical button, a capacitive button, and a pressure-sensitive button. For ease of description, the following description will primarily use a mechanical button as an example to illustrate the concept of this disclosure. It should be understood that the same applies to other types of buttons, and they will not be described in detail below.

[0061] In some embodiments, when the ring is worn, the button is located on the thumb side of the ring. This allows the user to easily press and operate the button. In some embodiments, the button unit 1053 is arranged in a cavity and configured to generate a press input signal in response to receiving a user press on the button. The press input signal can be transmitted to an external device via a communication unit, thereby providing input to the external device to achieve the corresponding function. Furthermore, in some embodiments, the press input signal can also be used to directly control the microphone unit 1051 and / or the speaker assembly 103 to turn on and off, as will be further explained below.

[0062] In some embodiments, for ease of button installation and user pressing, the housing 101 includes a button hole 1014, and the functional chamber also includes a button cavity corresponding to the button hole 1014. One end of the button is connected to the button unit 1053 inside the button cavity, and the other end of the button is exposed to the outside through the button hole 1014 for user pressing.

[0063] In some embodiments, to prevent moisture or dust from entering the cavity through the key hole 1014, the ring may also include a key sealing ring. The key sealing ring is disposed in the key cavity and surrounds the key hole 1014. The key sealing ring includes an insulating layer disposed between the key and the key unit 1053. In this way, the key unit 1053 can be effectively isolated in a sealed key cavity while still allowing the user to press the exposed key, thereby improving waterproofing and enhancing the user experience.

[0064] In some embodiments, the functional component may further include a processor. The processor is disposed within the functional chamber and is at least configured to control the microphone unit 1051 to turn on or off based on a press input signal. That is, the processing unit may be coupled to the button unit 1053 to cause the user to turn the microphone unit 1051 on or off in response to a press input signal generated by the user pressing the button. For example, when a user needs to input voice commands to an external device, they can turn on the microphone unit 1051 and input sound into the microphone unit 1051 by pressing and holding (or other suitable pressing method). In some embodiments, the processor may also control the speaker assembly 103 to turn on or off based on a press input signal.

[0065] Of course, it should be understood that the above examples of controlling the microphone unit 1051 and / or speaker assembly 103 to turn on or off via buttons are merely illustrative and are not intended to limit the scope of this disclosure. The buttons and button unit 1053 may also have other uses, and the microphone unit 1051 or speaker assembly 103 may be turned on or off in other ways. For example, in some embodiments, the press input signal emitted by the button unit 1053 may also provide corresponding input for other functions of an external device to achieve the corresponding function. In some embodiments, the microphone unit 1051 or speaker assembly 103 may also be turned on or off via control of an external device.

[0066] In some embodiments, the indicator unit 1052 in the functional components can provide light output. For example, the indicator unit 1052 is electrically connected to a communication unit to output light with a predetermined frequency and / or predetermined color, at least based on a control signal provided by the communication unit. For example, an external device can output a specified signal to the indicator unit 1052 via the communication unit. The indicator outputs flashing, constant light (for a predetermined time), single color, and / or alternating multi-color light according to the corresponding signal.

[0067] In some embodiments, the indicator light unit 1052 may be arranged in an indicator light cavity within a chamber. The indicator light cavity has a light output portion formed on its outer wall, thereby allowing light to be emitted from the indicator light cavity. In some embodiments, the light output portion may be a through hole formed on the outer wall. In this case, in order to maintain the airtightness of the indicator light cavity while allowing light to pass through, a light-transmitting but airtight material may be provided inside the through hole. In some embodiments, the light output portion may also be a transparent or translucent portion formed on the outer wall.

[0068] In some embodiments, the light output portion may have a suitable shape and size. For example, in some embodiments, the light output portion may be a through-hole for light to pass through, and the cross-sectional shape of the through-hole may include, but is not limited to, a circle, an ellipse, a square, a triangle, a star, a polygon, or other suitable regular or irregular shapes. In some embodiments, the indicator light cavity 1015 also has a light output portion formed on the sidewall. In such embodiments, alternatively or additionally, the light output portion may also be a light strip extending along a portion of the ring's contour. That is, the light output portion formed on the sidewall may have a semi-circular or annular shape.

[0069] In some embodiments, the vibrator unit in the functional component is arranged in a functional chamber and electrically connected to a communication unit to vibrate at least based on a control signal provided by the communication unit.
