[0037] 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.

[0038] Figures 1 to 3 The overall or partial schematic structure of the nose pad module according to embodiments of the present invention is shown from different angles.

[0039] like Figures 1 to 3As shown in the figure, the nose pad 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 6 disposed on the module bracket, and a first microphone 51 and a second microphone 52 arranged in parallel on the circuit board 6. A soft rubber nose pad 2 is also disposed on the module bracket, covering the circuit board 6, the first microphone 51 and the second microphone 52. The soft rubber nose pad 2 is in direct contact with the user, which can improve wearing comfort. At the same time, the dual microphones enrich the function of the nose pad module and improve the accuracy of user's mouth sound signal recognition.

[0040] The module bracket further includes a gearbox 1, a lower gear 11 (drive gear) disposed within the gearbox 1, and an upper gear 7 that is confined within the gearbox 1 and meshes with the lower gear 11. The upper gear 7 is fixedly connected to the circuit board 6. By driving the upper gear 7 through the lower gear 11, the tilt angle of the circuit board 6 can be adjusted. The gearbox 1 is a box-like structure, and a power component that drives the lower gear 11 can be disposed inside it. This power component is connected to the control unit of the nose pad module or the control unit of a smart wearable device equipped with a nose pad module. The control unit sends drive command information to control the movement of the lower gear 11. Furthermore, through the meshing of the lower gear 11 with the upper gear 7, the upper gear 7 and the circuit board 6 on it are controlled to move, thereby adjusting the pickup angle of the first microphone 51 and the second microphone 52 to achieve multi-angle, full-range pickup effects.

[0041] Furthermore, to facilitate the positioning between the upper gear 7 and the circuit board 6, an extension 4 extending from the gearbox 1 can be provided on one side of the upper gear 7. The side of the extension 4 away from the gearbox 1 forms a plate-shaped or groove-shaped limiting structure, that is, one side of the extension 4 can form a structure similar to a support plate. The circuit board 6 is directly attached and positioned on the extension 4. The soft nose pad 2 can be wrapped around the extension 4 and the circuit board 6 after molding, or it can be directly formed on the extension 4 and the circuit board 6 by wrapping. The present invention does not specifically limit the formation method of the soft nose pad 2. The movement of the extension 4 can drive the circuit board 6 to move synchronously and complete the position adjustment of the microphone on it.

[0042] In addition, a rotating shaft 8 can be provided inside the gearbox 1. At the same time, two corresponding limiting holes can be provided inside the gearbox 1. A fixing hole is provided through the upper gear 7 at the center position of the upper gear 7. After the upper gear 7 and the lower gear 11 are meshed, the fixing hole is located between the two limiting holes. At this time, the upper gear 7 is moved and limited by the rotating shaft 8 passing through the two limiting holes and the fixing hole. Similarly, the lower gear 11 can also be positioned by the corresponding rotating shaft 8 to ensure that the two can mesh normally.

[0043] It should be noted that the angle adjustment range of the circuit board 6 is related to the rotation angle of the upper gear 7. Specifically, the angle adjustment range of the circuit board 6 can be limited according to the limiting structure between the extension 4 and the gearbox 1 to ensure that the microphone can effectively pick up sound signals within this range. In this invention, the upper gear 7 can adopt a half gear head structure, which can be combined with the extension 4 to form an integrated structure.

[0044] In one specific embodiment of the present invention, an upper vent 41 communicating with the first microphone 51 is provided in the extension 4, and a lower vent 21 communicating with the second microphone 52 is reserved in the soft rubber nose pad 2. The upper vent 41 and the lower vent 21 are respectively located on both sides of the extension 4. The first microphone 51 collects sound signals through the upper vent 41, and the second microphone 52 collects sound signals through the lower vent 21. The two microphones can achieve 180-degree sound collection. Then, by delaying and aligning the sound signals, an omnidirectional sound pickup effect is achieved. In addition, automatic calibration can be performed based on the signals of the first microphone 51 and the second microphone 52. Then, in conjunction with the control unit, the first microphone 51 and the second microphone 52 are adjusted to the optimal sound pickup angle through the upper gear 7 and the lower gear 11.

[0045] As can be seen, in the application of the nose bridge module, both the first microphone 51 and the second microphone 52 are used to pick up sound signals. The external control unit sends a drive signal, i.e., drive command information, to the lower gear 11 according to the sound signal. The lower gear 11 drives the upper gear 7 to move according to the drive signal to adjust the sound pickup direction of the first microphone 51 and the second microphone 52. It can adjust the two microphones to the optimal sound pickup angle according to the difference of the scene, thereby improving the accuracy and omnidirectionality of sound pickup.

[0046] Furthermore, a wire groove can be provided in the extension 4, and the circuit board 6 can be electrically connected to external components through wires located in the wire groove. The external components here include other components in the smart wearable device that is equipped with the nose pad module, such as the control unit of the smart wearable device that is equipped with the nose pad module of the present invention.

[0047] In another specific embodiment of the present invention, an outer conduit 3 may be provided on the upper side of the gearbox 1. One end of the outer conduit 3 is connected to the wire groove, and the other end is connected to the connecting bracket. The connection between the nose wing module and the connecting bracket is realized through the outer conduit 3. The nose wing module may include a left nose wing module and a right nose wing module. The left nose wing module and the right nose wing module are detachably electrically connected to the connecting bracket, and the detachable electrical connection can be realized through the outer conduit 3 and the wire and corresponding connector located in the outer conduit 3. For example, a connector may be provided at the end of the outer conduit 3, and the detachable connection with the connecting bracket can be made through the connector.

[0048] 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.

[0049] According to the nose pad module and smart wearable device of the present invention, a first microphone and a second microphone are arranged side by side on the circuit board on the module bracket, and then a soft rubber nose pad is set on the module bracket, covering the circuit board, the first microphone and the second microphone. Sound is collected through vents in both the front and back directions, which can realize multi-angle sound pickup. At the same time, with the help of the micro gearbox structure, the microphone angle can be automatically adjusted, improving the sound pickup quality and the flexibility of sound pickup, and meeting the user's need for higher performance.

[0050] 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.
