[0029] To provide a detailed description of the nose pad module and smart wearable device of the present invention, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Figures 1 to 4 The overall or partial schematic structure of the nose pad module according to embodiments of the present invention is shown from different angles.

[0031] like Figures 1 to 4 As shown in the figure, the nose bridge module of this embodiment includes a connecting bracket and nose wing modules symmetrically arranged at both ends of the connecting bracket; wherein, each nose wing module further includes a module bracket, a circuit board 7 disposed in the module bracket and a microphone disposed on the circuit board 7, and an adjustable guide tube 3 is also disposed in the module bracket. One end of the adjustable guide tube 3 corresponds to the position of the microphone's pickup hole, and the other end extends to the outside of the module bracket. By adjusting the angle or position of the adjustable guide tube 3, the recognition of voice signals from multiple positions can be realized, thereby improving the accuracy and flexibility of voice recognition.

[0032] The adjustable guide tube 3 further includes a fixed tube 31 that is limited and fixed within the module bracket, and an adjusting tube 32 that is movably connected to the fixed tube 31. One end of the fixed tube 31 is sealed to the microphone's pickup hole, and the other end extends to the adjusting tube 32. The pickup position can be changed by rotating the adjusting tube 32. It can be seen that one end of the adjusting tube 32 can rotate around the fixed tube 31; or, based on the sealed connection between the adjusting tube 32 and the fixed tube 31, rotating the adjusting tube 32 around the module bracket can also change the position of the other end of the adjusting tube 32.

[0033] Specifically, when the adjusting tube 32 and the fixed tube 31 are connected by a thread or by a combination of limiting grooves and buckles, the rotation angle of the adjusting tube 32 is not less than 180°. The position of the tube opening of the adjusting tube 32 can be located below or on both sides of the module bracket, which can pick up the voice signal near the wearer's mouth from multiple angles, realize the adjustment of the sound source direction, and achieve the purpose of improving the accuracy and stability of sound signal acquisition.

[0034] To prevent over-adjustment of the adjustment tube 32, two limiting protrusions can be provided on the module bracket. During rotation, the adjustment tube 32 can be limited within these two protrusions for position adjustment. Furthermore, a dustproof protective film can be installed inside the opening of the adjustment tube 32. When the opening of the adjustment tube 32 faces outwards from the module bracket, the dustproof protective film can isolate external foreign objects, ensuring the stability and reliability of the nose pad module's performance.

[0035] In one specific embodiment of the present invention, the module support includes a fixed shell 51, an adjustable shell 52 movably connected to the fixed shell 51, and a soft rubber nose pad 1 disposed on the adjustable shell 52. The circuit board 7 is fixed on the adjustable shell 52, and the soft rubber nose pad 1 covers the circuit board 7 and the microphone. The adjustable shell 52 and the fixed shell 51 can be movably connected through various means such as a rotating shaft 4. During the process of the user wearing the nose pad module, the position of the adjustable shell 52 can be adjusted by the adaptation between the adjustable shell 52 and the user's nose position, so that the soft rubber nose pad 1 on the adjustable shell 52 can directly contact the user's skin, thereby improving the wearing comfort.

[0036] One side of the adjusting shell 52 is movably connected to the fixed shell 51, and the other side can form a plate-shaped or shallow groove-shaped structure. The soft rubber nose pad 1 can be wrapped around the adjusting shell 52 and the circuit board 7 after molding, or it can be directly formed into an integrated structure by wrapping the adjusting shell 52 and the circuit board 7 with glue. The present invention does not specifically limit the forming method of the soft rubber nose pad 1.

[0037] Specifically, at least one microphone can be provided on the circuit board 7, for example, it can include a first microphone 61 and a second microphone 62; wherein, the first microphone 61 and the second microphone 62 are used to collect sound signals from different positions. For example, a rear through hole 8 communicating with the first microphone 61 can be provided on the adjustment shell 52. The pickup hole and the rear through hole 8 are located on both sides of the circuit board 7, and the aforementioned adjustable guide tube 3 is connected to the second microphone 62 located below. By delaying and aligning the sound signals of the first microphone 61 and the second microphone 62, an omnidirectional sound pickup effect can be achieved.

[0038] In addition, in another specific embodiment of the present invention, a conduit 2 may be provided on the fixed shell 51; wherein, a wire connected to the circuit board 7 is provided in the conduit 2, one end of the conduit 2 is connected to the circuit board 7, and the other end is connected to the connecting bracket, and the connection with external control unit or chip and other components is realized through the connecting bracket. The external control unit may be other control chips of the head-worn smart device equipped with the nose pad module of the present invention.

[0039] Furthermore, the nose wing module may include a left nose wing module and a right nose wing module, which are detachably electrically connected to the connecting bracket. This detachable electrical connection can be achieved through the conduit 2, the wires located within the conduit 2, and the corresponding connectors. For example, a connector can be provided at the end of the conduit 2, and the detachable connection can be made with the connecting bracket through the connector.

[0040] In another invention, the present invention also provides a smart wearable device, including the aforementioned nose pad module. It should be noted that embodiments of the smart wearable device can be found in the descriptions of the nose pad module embodiments, and will not be repeated here.

[0041] According to the nose pad module and smart wearable device of the present invention, an adjustable guide tube is provided in the module bracket. One end of the adjustable guide tube corresponds to the position of the microphone's pickup hole, and the other end extends to the outside of the module bracket. The angle of the adjustable guide tube is adjustable, which can achieve multi-angle sound pickup effect and improve the flexibility and accuracy of sound pickup. In addition, omnidirectional sound pickup effect can be achieved through two microphones with different pickup directions to meet the user's demand for higher performance.

[0042] The nose pad module and smart wearable device according to the present invention have been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the nose pad module and smart wearable device proposed in the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the content of the appended claims.
