Even after noise reduction algorithms are applied, the voice signal cannot be effectively extracted, resulting in suboptimal call and voice wake-up / recognition performance, or even inability to function properly.

[0049] With the increasing development of computers, electronic technology, and network application technology, electronic devices such as smart glasses are gradually entering people's lives.

[0050] Currently, smart wearable devices such as smart audio glasses and AR / VR all have functions such as calls and voice wake-up / recognition. Due to the trend towards thinner and lighter smart wearable devices, the demand for them in increasingly diverse scenarios. However, in outdoor and industrial settings, voice signals picked up by microphones are easily overwhelmed by wind noise and high-level noise (ambient noise). Even after noise reduction algorithms are applied, the voice signal cannot be effectively extracted, resulting in suboptimal calls and voice wake-up / recognition performance, or even inability to function properly. Therefore, a voice recognition architecture is urgently needed to address these issues.

[0051] In view of this, the present invention provides a nose pad. FIG1 to FIG9 are embodiments of the nose pad provided by the present invention. The nose pad will be described below with reference to specific drawings.

[0052] Referring to Figures 1 to 9, the nose pad 100 is used for smart glasses 1000, wherein the nose pad 100 includes a support member 1 and a bone conduction component 2. The support member 1 includes two support portions for being placed on both sides of the nose, wherein one of the support portions is a first support portion 11, and the first support portion 11 has a first side 111 and a second side 112 opposite to each other; the bone conduction component 2 includes a vibration module 21 and a MEMS module 22, wherein the vibration module 21 is provided on the first side 111 of the first support portion 11, and the MEMS module 22 is provided on the first side 111 of the first support portion 11. 22 is arranged on the second side 112 of the first supporting part 11, the vibration module 21 has a vibration cavity 211, and the MEMS module 22 has a detection port 221a, and the detection port 221a is connected to the vibration cavity 211. The vibration module 21 is used to pick up the vibration of the user when speaking, so as to vibrate the air in the vibration cavity 211, and the MEMS module 22 is used to pick up the vibration signal of the user's voice through the vibrating air in the vibration cavity 211, and feed the vibration signal back to the control device on the smart glasses 1000.

[0053] In the technical solution of the present invention, in order to avoid the influence of environmental wind noise and environmental noise on the smart glasses 1000 picking up the user voice signal, the detection port 221a of the MEMS module 22 is connected with the vibration cavity 211 of the vibration module 21, and the vibration module 21 receives the user's pronunciation vibration and generates corresponding air flow inside the vibration cavity 211 thereof to convert the structural vibration into air vibration. The air vibration is transmitted through the connection between the detection port 221a and the vibration cavity 211 and is recognized by the MEMS module 22. In this way, the generation and detection of the air vibration are combined. The detection and recognition are all in the communication structure between the detection port 221a and the vibration cavity 211. External wind noise and high noise cannot affect it. The air vibration is generated by the vibration module 21 receiving the user's voice vibration, which is associated with the user's voice signal. In this way, the MEMS module 22 can detect and recognize the user's voice signal and avoid the detection and recognition of environmental wind noise and environmental noise, greatly reducing the impact of environmental wind noise and environmental noise on the pickup of the user's voice signal, so that the smart glasses 1000 can effectively extract the user's voice signal in a complex noise environment, meeting the use requirements of complex environments. Based on this, the vibration module 21 in this application mainly uses bone conduction to receive the user's voice vibration. Since the position of the nose pad 100 is better when the human bone vibrates during speaking, the bone conduction vibration perception of the vibration module 21 set on the nose pad 100 is also better, which can generate a high-sensitivity, high-signal-to-noise ratio voice vibration signal, thereby greatly improving the quality of the acquired voice signal, achieving a good call noise reduction effect, and a high wake-up rate and high recognition rate voice wake-up / recognition effect.

[0054] It should be noted that the vibration module 21 and the MEMS module 22 provided on the first support portion 11 are provided independently of each other, and can ensure that the detection port 221a is stably connected to the vibration cavity 211. Therefore, there can be multiple ways of connection. Therefore, the positional relationship between the vibration module 21 and the MEMS module 22 does not need to be limited. The vibration module 21 and the MEMS module 22 can be connected by setting a corresponding connection method to meet the above-mentioned stable connection requirements. In this application, the structure in which the vibration module 21 and the MEMS module 22 are provided on two side surfaces of the first support portion 11, namely the first side 111 and the second side 112, is specifically described. In addition, the MEMS (micro-electromechanical system) microphone is used in this application. Its structural volume is smaller, so as to reduce the structural volume of the bone conduction component 2, making it easier to set it on the smaller nose pad 100 structure. The sensitivity of the MEMS (micro-electromechanical system) microphone is more stable, not easily affected by environmental changes, and more practical.

[0055] Specifically, in the first embodiment of the nose pad 100 (see FIG3 ), the first supporting portion 11 is provided with a connecting hole 113 running through the first side 111 and the second side 112 thereof; the vibration cavity 211 is connected to one end of the connecting hole 113, and the detection port 221a is connected to the other end of the connecting hole 113, so that the detection port 221a is connected to the vibration cavity 211. The vibration cavity 211 and the MEMS module 22 are respectively arranged on both sides of the first supporting portion 11. In this embodiment, in order to shorten the communication path between the two as much as possible, the connecting hole 113 is opened on the first supporting portion 11, and the vibration cavity 211 is connected to the detection port 221a of the MEMS module 22 via the connecting hole 113. In this way, the attenuation of the airflow fluctuation caused by the communication path is reduced, thereby improving the quality of the acquired voice signal.

[0056] It is understandable that the communication channel formed after the vibration cavity 211 is connected to the MEMS module 22 can be a completely closed structure or a common docking structure, that is, there is no need to consider non-closed structures such as gaps, as long as the above-mentioned communication channel is stably connected and can play the required function. However, setting the communication channel as a closed structure is obviously more able to isolate external interference and has a better effect. Therefore, in this application, the vibration cavity 211, the connecting hole 113 and the inner cavity of the MEMS module 22 are connected to form a closed cavity. Specifically, the method of forming the closed structure is not limited here, including but not limited to sealant sealing, contact surface gasket sealing, etc., as long as the sealing function can be achieved.

[0057] In addition, in the second to sixth embodiments of the nose pad 100 (see Figures 4 to 8), the detection port 221a is connected to the vibration cavity 211 through the connecting cavity 6. According to the method in the first embodiment of the nose pad 100 mentioned above, the vibration cavity 211 and the detection port 221a on the MEMS module 22 must be arranged relative to each other on the first side 111 and the second side 112 of the first support portion 11. The position setting is not flexible and may be inapplicable. Therefore, other embodiments are also provided in this application, specifically including the second to sixth embodiments of the nose pad 100 (see Figures 4 to 8), in which the connecting cavity 6 is arranged between the vibration cavity 211 of the vibration module 21 and the detection port 221a of the MEMS module 22. , in order to connect the two, the connecting cavity 6 only needs to cover the opening of the vibration module 21 and the detection port 221a of the MEMS module 22, so as to connect the vibration cavity 211 in the vibration module 21 with the detection port 221a on the MEMS module 22. There is no need for precise alignment, and the assembly is simple. In addition, the setting of the connecting cavity 6 is relatively free, and there is no need to limit the relative position between the vibration module 21 and the MEMS module 22, which can be convenient for specific setting. At the same time, the structural design is simple, easy to design and manufacture, can meet various structural forms, and is more applicable.

[0058] It can be understood that, similar to the above-mentioned communication method of directly connecting the detection port 221a on the MEMS module 22 and the vibration cavity 211 through the connecting hole 113 opened in the first support part 11 to directly connect the vibration cavity 211 and the detection port 221a, the method of connecting the detection port 221a and the vibration cavity 211 through the connecting cavity 6 in this embodiment can also be a completely closed structure or an ordinary docking structure. Based on the same recognition as above, the connecting cavity 6 in this embodiment connects the vibration cavity 211 and the detection port 221a to form a closed cavity, thereby improving the effect of isolating external interference and achieving better sound reception effect.

[0059] Specifically, in the second embodiment and the third embodiment of the nose pad 100 proposed in the present application (see Figures 4 to 5), the first side 111 of the first support part 11 is also provided with a sealed shell 3, and the sealed shell 3 is located next to the vibration membrane block and is arranged corresponding to the MEMS module 22. The sealed shell 3, the vibration module 21 and the first side 111 of the first support part 11 are jointly enclosed to form the connecting cavity 6; the side wall of the vibration cavity 211 adjacent to the connecting cavity 6 is provided with an exhaust hole 211a, and the vibration cavity 211 is connected with the connecting cavity 6 through the exhaust hole 211a; the first support part 11 is provided with a first connecting hole 114 running through its first side 111 and the second side 112, and the first connecting hole 114 connects the connecting cavity 6 and the detection port 221a. On the basis that the vibration module 21 and the MEMS module 22 are respectively arranged on both sides of the first support part 11, the first connecting hole 114 is opened on the first support part 11 to shorten the connecting path. The first connecting hole 114 can be used to connect the vibration cavity 211 and one of the detection port 221a. In this embodiment, the first connecting hole 114 is used to connect the detection port 221a, and the first side 111 of the first support part 11 is provided with a sealed shell 3 with one end overlapping the vibration module 21 and the other end supported by the first side 111 of the first support part 11. The sealed shell 3, the outer wall of the vibration module 21 and the first side 111 are enclosed to form the connecting cavity 6, and the exhaust hole 211a opened on the vibration cavity 211 is arranged corresponding to the connecting cavity 6. At the same time, the first connecting hole 114 on the first support part 11 is also arranged corresponding to the connecting cavity 6. In this way, the technical solution of connecting the detection port 221a and the exhaust hole 211a through the connecting cavity 6 and the first connecting hole 114 is realized.

[0060] In addition, the nose pad 100 further includes a covering shell 4 covering the first supporting portion 11 . The vibration module 21 and the MEMS module 22 are both disposed in the covering shell 4 . The inner cavity of the covering shell 4 forms the communicating cavity 6 . In some embodiments of the nose pad 100, only the covering function of the covering shell 4 is required to enhance the user's wearing experience, while in some embodiments, an inner cavity is required to be provided in the covering shell 4 to form the connecting cavity 6. In the fourth embodiment (see FIG6 ) and the fifth embodiment (see FIG7 ) of the nose pad 100 proposed in the present application, an inner cavity is provided in the covering shell 4, so that the covering shell 4 and the first supporting portion 11 are enclosed to form the connecting cavity 6. The vibration module 21 and the MEMS module 22 are placed in the covering shell 4, and the connecting cavity 6 connects the exhaust hole 211a of the vibration cavity 211 in the vibration module 21 with the detection port 221a on the MEMS module 22 to achieve connection between the two. Obviously, this structural setting does not require the addition of additional structures to form the connecting cavity 6, has fewer parts, is convenient for assembly, and reduces costs.

[0061] Specifically, in the fourth embodiment of the nose pad 100 proposed in this application (see FIG6 ), the vibration module 21 is provided with an exhaust hole 211a on the side facing away from the first support portion 11. The exhaust hole 211a connects the inner cavity of the covering shell 4 and the vibration cavity 211. The first support portion 11 is provided with a second communication hole 115 that passes through the first side 111 and the second side 112 thereof. The second communication hole 115 connects to the detection port 221a. In this embodiment, for the same reason as described above, the second communication hole 115 is provided on the first support portion 11 to connect to the detection port 221a. The exhaust hole 211a provided on the vibration module 21 connects to the second communication hole 115 through the inner cavity of the covering shell 4, and then connects to the detection port 221a. This achieves a technical solution in which the detection port 221a and the exhaust hole 211a are connected through the communication cavity 6 and the second communication hole 115.

[0062] In addition, in the fifth embodiment of the nose pad 100 proposed in the present application (see FIG7 ), the second side 112 of the first supporting portion 11 is provided with an exhaust hole 211a communicating with the vibration cavity 211, and the exhaust hole 211a is provided to communicate with the inner cavity of the covering shell 4 and the vibration cavity 211. In contrast to the fourth embodiment, the opening on the first supporting portion 11 is used to directly communicate with the vibration cavity 211, that is, the opening forms the exhaust hole 211a on the vibration cavity 211. Therefore, in this embodiment, the inner cavity of the covering shell 4 is mainly used to communicate with the detection port 221a, and then the inner cavity is used to communicate with the exhaust hole 211a provided on the second supporting portion, and then communicate with the vibration cavity 211, thereby realizing a technical solution in which the detection port 221a and the vibration cavity 211 are communicated with the exhaust hole 211a on the first supporting portion 11 through the connecting cavity 6.

[0063] In addition, in the sixth embodiment of the nose pad 100 proposed in the present application (see Figure 8), the second side 112 of the first support part 11 is provided with an exhaust hole 211a connected to the vibration cavity 211; the second side 112 of the first support part 11 is also provided with a cover 5, and the cover 5 covers the exhaust hole 211a and the MEMS module 22, and the cover 5 and the second side 112 of the first support part 11 enclose the connecting cavity 6. Similarly, in this embodiment, an opening is provided on the first support portion 11, and the exhaust hole 211a connected to the vibration cavity 211 is formed by the opening. At this time, the starting end of the exhaust hole 211a and the MEMS module 22 are located on the second side 112 of the first support portion 11. In this embodiment, the cover 5 is directly provided on the second side 112 to cover the MEMS module 22 and the exhaust hole 211a through the cover 5. The cover 5 and the second side 112 of the first support portion 11 are enclosed to form the connecting cavity 6. The detection port 221a of the MEMS module 22 accommodated in the connecting cavity 6 is located in the connecting cavity 6, thereby realizing the technical solution of the detection port 221a and the exhaust hole 211a being connected through the connecting cavity 6.

[0064] In addition, the vibration module 21 is provided with an exhaust hole 211a that communicates with the vibration cavity 211, and the exhaust hole 211a is connected to the detection port 221a. The exhaust hole 211a is provided at the end of the vibration module 21 facing away from the first support portion 11; or, the exhaust hole 211a is provided on the side of the vibration module 21; or, the exhaust hole 211a is provided through the second side 112 of the first support portion 11 to communicate with the vibration cavity 211. It is understood that the specific location of the exhaust hole 211a on the vibration module 21 that communicates with the vibration cavity 211 depends on the actual connection method between the vibration module 21 and the MEMS module 22. Based on the above embodiment, this application mainly proposes three configuration methods, including but not limited to being provided at the end of the vibration module 21 facing away from the first support portion 11, being provided on the side of the vibration module 21, and being provided through the first support portion 11. These configuration methods are based on actual needs and are not specifically limited, as long as they can meet the connection requirements.

[0065] In addition, the MEMS module 22 includes a MEMS sensor and a circuit board 222, wherein the detection port 221a is provided on the MEMS sensor, and the MEMS sensor is electrically connected to the circuit board 222. The MEMS sensor needs to be electrically connected to the control device on the smart glasses 1000 via an electrical connection structure. The electrical connection structure can be a connecting wire structure, that is, the MEMS sensor is fixed to the first support part 11, and then connected to the MEMS sensor via the connecting wire structure to connect to the control device on the smart glasses 1000. In this application, the circuit board 222 is attached to the first support part 11, and the MEMS sensor is patched on the circuit board 222 to position and fix the MEMS sensor and connect it to the control device of the smart glasses 1000. This facilitates installation and operation and has strong stability. It should be noted that, in the above scheme, it is necessary to open an opening on the first support part 11 so that when the detection port 221a on the MEMS sensor is docked with the opening, the circuit board 222 should adaptively open an avoidance hole at the corresponding position to meet the docking requirements of the MEMS sensor and the opening. At the same time, in order to ensure the degree of sealing at the docking point, a sealing gasket can also be arranged between the circuit board 222 and the first support part 11, and the sealing gasket can be arranged in a ring shape to enclose the opening and the avoidance hole.

[0066] Specifically, the vibration module 21 includes a diaphragm 212 disposed in the vibration cavity 211. The vibration module 21 is mainly used to receive the vibration generated when the user speaks and convert it into air vibration in the vibration cavity 211. That is, the vibration module 21 needs to be provided with a structure that vibrates when the user speaks to disturb the air in the vibration cavity 211. There are many types of such structures, including vibration rods, vibration membranes and other structures, all of which can achieve similar functions. In this application, the embodiment of disposing the diaphragm 212 in the vibration cavity 211 is mainly adopted. The solution is more mature in the acoustic structure, so as to make it more stable. In addition, it can be understood that the diaphragm 212 can also serve as the cavity wall of the vibration cavity 211, but its vibration direction is bidirectional. Even if it is set in this way, an avoidance space still needs to be set on the side facing away from the vibration cavity 211. Therefore, the present application directly sets the diaphragm 212 to be located in the vibration cavity 211 and covers a cross-section of the vibration cavity 211 so that it has a bidirectional vibration space. At the same time, the diaphragm 212 is built into the vibration cavity 211, which also plays a certain protective effect.

[0067] Furthermore, the vibration module 21 also includes a mass block 213 disposed on the diaphragm 212. The diaphragm 212 generally has a light structure and mass, resulting in a small inertia. When the vibration module 21 vibrates with the user's nose, the diaphragm 212 cannot follow the movement in time, and is affected by the air resistance in the vibration cavity 211, resulting in a small vibration amplitude, which affects the generation of air flow fluctuations in the vibration cavity 211 and thus affects the subsequent sound pickup quality. Therefore, the present application sets the mass block 213 on the diaphragm 212 to improve the above situation without affecting the function of the vibration of the diaphragm 212 to drive the air flow fluctuations in the vibration cavity 211.

[0068] In addition, the nose pad 100 also includes a mounting portion 7 connected to the support member 1, and the mounting portion 7 is used to be detachably mounted on the glasses body 200 of the smart glasses 1000. The nose pad 100 can be integrally formed with the smart glasses 1000, but considering that the electronic components are installed in the nose pad 100 and may require subsequent maintenance, repair, and replacement, the present application provides that the nose pad 100 is detachably connected to the smart glasses 1000, and the mounting portion 7 for detachable connection with the smart glasses 1000 is provided as an independent detachable structure.

[0069] It should be noted that the closed channel can be set to a longer structure. For example, in some specific needs, it is necessary to bypass the closed channel on the basis of connecting the vibration module 21 and the MEMS module 22. This structural form can also form the above-mentioned closed structure. Although the longer the closed channel, the greater the impact on the propagation of airflow, which in turn affects the acquisition of user voice signals, it is sufficient to meet the set requirements. Based on actual usage needs, there is no need to limit the closed channel to the shortest structural form connecting the vibration module 21 and the MEMS module 22 in the above embodiments. On the basis of the above embodiments, the closed channel can be bypassed to extend its path to meet specific usage needs.

In addition, it can be understood that the diaphragm 212 can also serve as the cavity wall of the vibration cavity 211, but its vibration direction is bidirectional. Even if it is set in this way, it is still necessary to set an avoidance space on the side facing away from the vibration cavity 211. Therefore, this application directly sets the diaphragm 212 to be located in the vibration cavity 211 and covers a cross-section of the vibration cavity 211, so that it has a bidirectional vibration space.

Furthermore, the vibration module 21 also includes a mass block 213 disposed on the diaphragm 212. The diaphragm 212 is generally light in structure, resulting in a small inertia. When the vibration module 21 vibrates with the user's nose, the diaphragm 212 cannot follow the movement in time, and it is affected by the gas resistance in the vibration cavity 211, resulting in a small vibration amplitude, which affects the generation of air flow fluctuations in the vibration cavity 211, thereby affecting the subsequent sound pickup quality.

The nose pad 100 may be integrally formed with the smart glasses 1000, but considering that the electronic devices are arranged in the nose pad 100, there may be later maintenance, repair and replacement. In this application, the nose pad 100 is set to be detachably connected to the smart glasses 1000, and the mounting portion 7 for detachably connecting to the smart glasses 1000 is set as an independent detachable structure. It should be noted that the closed channel can be set to a structure with a longer size. For example, in some specific needs, it is necessary to bypass the closed channel on the basis of connecting the vibration module 21 and the MEMS module 22. This structural form can also form the above-mentioned closed structure. Although the longer the closed channel is, the greater the impact on the propagation of airflow, which in turn affects the acquisition of user voice signals, it is sufficient to meet the set requirements. It is mainly based on actual usage needs. There is no need to limit the closed channel to the shortest structural form connecting the vibration module 21 and the MEMS module 22 in the above-mentioned embodiments.

In addition, the vibration module 21 is provided with an exhaust hole 211a connected to the vibration cavity 211, and the exhaust hole 211a is connected to the detection port 221a: wherein, The exhaust hole 211a is arranged at the end of the vibration module 21 facing away from the first support part 11; or, the exhaust hole 211a is arranged at the side of the vibration module 21; or, the exhaust hole 211a connected to the vibration cavity 211 is penetrated from the second side 112 of the first support part 11. It can be understood that the specific setting position of the exhaust hole 211a on the vibration module 21 connected to the vibration cavity 211 is mainly based on the actual connection method between the vibration module 21 and the MEMS module 22. Based on the above embodiments, three setting methods are mainly proposed in this application, including but not limited to setting at the end of the vibration module 21 facing away from the first support part 11, setting at the side of the vibration module 21, and penetrating on the first support part 11. It is mainly based on actual needs and is not specifically limited. It only needs to meet the connection requirements. In addition, the MEMS module 22 includes a MEMS sensor and a circuit board 222, wherein the detection port 221a is provided on the MEMS sensor, and the MEMS sensor is electrically connected to the circuit board 222. The MEMS sensor needs to be electrically connected to the control device on the smart glasses 1000 through an electrical connection structure, and the electrical connection structure can be a connecting wire structure, that is, the MEMS sensor is fixed on the first support part 11, and then connected to the MEMS sensor through the connecting wire structure to connect to the control device on the smart glasses 1000. In this application, the circuit board 222 is attached to the first support part 11, and the MEMS sensor is pasted on the circuit board 222 to position and fix the MEMS sensor and connect it to the control device of the smart glasses 1000, which is convenient for installation and operation, and has strong stability. It should be noted that, in the above scheme, it is necessary to open an opening on the first support part 11 so that when the detection port 221a on the MEMS sensor is docked with the opening, the circuit board 222 should adaptively open an avoidance hole at the corresponding position to meet the docking requirements of the MEMS sensor and the opening. At the same time, in order to ensure the degree of closure at the docking point, a sealing gasket can also be arranged between the circuit board 222 and the first support part 11, and the sealing gasket can be arranged in a ring shape to enclose the opening and the avoidance hole. Specifically, the vibration module 21 includes a diaphragm 212 disposed in the vibration cavity 211. The vibration module 21 is mainly used to receive the vibration when the user speaks, and convert it into air vibration in the vibration cavity 211, that is, the vibration module 21 needs to be provided with a structure that vibrates when the user speaks to disturb the air in the vibration cavity 211. There are many types of such structures, including vibration rods, vibration membranes, etc. And reduce costs.

In contrast to the fourth embodiment, the opening on the first supporting portion 11 is used to directly connect to the vibration cavity 211, that is, the opening forms the exhaust hole 211a on the vibration cavity 211.

The cover 5 and the second side 112 of the first support portion 11 are enclosed to form the connecting cavity 6, and the MEMS module 22 contained in the connecting cavity 6 is contained in the connecting cavity 6. Specifically, in the second embodiment and the third embodiment of the nose pad 100 proposed in the present application (see Figures 4 to 5), a sealing shell 3 is further provided on the first side 111 of the first supporting portion 11, and the sealing shell 3 is located next to the vibration membrane block and is arranged corresponding to the MEMS module 22, and the sealing shell 3, the vibration module 21 and the first side 111 of the first supporting portion 11 together enclose a connecting cavity 6; the side wall of the vibration cavity 211 adjacent to the connecting cavity 6 is provided with an exhaust hole 211a, and the vibration cavity 211 is connected with the connecting cavity 6 through the exhaust hole 211a; the first supporting portion 11 is provided with a first connecting hole 114 running through its first side 111 and the second side 112, and the first connecting hole 114 connects the connecting cavity 6 and the detection port 221a. On the basis that the vibration module 21 and the MEMS module 22 are respectively arranged on both sides of the first support part 11, the first connecting hole 114 is opened on the first support part 11 to shorten the connecting path. The first connecting hole 114 can be used to connect the vibration cavity 211 and one of the detection port 221a. In this embodiment, the first connecting hole 114 is used to connect the detection port 221a, and the first side 111 of the first support part 11 is provided with a sealed shell 3 with one end overlapped on the vibration module 21 and the other end supported on the first side 111 of the first support part 11. The sealed shell 3 and the outer wall of the vibration module 21 and the first side 111 are surrounded to form the connecting cavity 6, and the exhaust hole 211a opened on the vibration cavity 211 is arranged corresponding to the connecting cavity 6. At the same time, the first connecting hole 114 on the first support part 11 is also arranged corresponding to the connecting cavity 6. In this way, the technical solution of connecting the detection port 221a and the exhaust hole 211a through the connecting cavity 6 and the first connecting hole 114 is realized. In addition, the nose pad 100 further includes a covering shell 4 that covers the first supporting portion 11 , the vibration module 21 and the MEMS module 22 are both disposed in the covering shell 4 , and the inner cavity of the covering shell 4 forms the connecting cavity 6 . In some embodiments of the nose pad 100, only the covering function of the covering shell 4 is used to enhance the wearing experience of the user, and in some embodiments, an inner cavity is further provided in the covering shell 4 to form the connecting cavity 6. In the fourth embodiment (see FIG. 6 ) and the fifth embodiment (see FIG. 7 ) of the nose pad 100 proposed in the present application, an inner cavity is provided in the covering shell 4 so that the covering shell 4 and the first supporting portion 11 are enclosed to form the connecting cavity 6, the vibration module 21 and the MEMS module 22 are placed in the covering shell 4, and the connecting cavity 6 connects the exhaust hole 211a of the vibration cavity 211 in the vibration module 21 with the detection port 221a on the MEMS module 22 to achieve the connection between the two. Obviously, this structural setting does not require the addition of additional structures to form the connecting cavity 6, has fewer parts, and is easy to assemble. 113 is connected, thus reducing the attenuation of airflow fluctuations by the connection path to improve the quality of the acquired voice signal. It is understandable that the connecting channel formed after the vibration cavity 211 is connected with the MEMS module 22 can be a completely closed structure or a common docking structure, that is, a non-closed structure without considering gaps, etc., which can ensure the stable connection of the above-mentioned connecting channel and play the required function. However, setting the connecting channel as a closed structure is obviously more able to isolate external interference and has a better effect. Therefore, in this application, the vibration cavity 211, the connecting hole 113 and the inner cavity of the MEMS module 22 are connected to form a closed cavity. Specifically, the method of forming a closed structure is not limited here, including but not limited to sealant sealing, contact surface sealing gasket sealing, etc., as long as the sealing function can be achieved. In addition, in the second to sixth embodiments of the nose pad 100 (see FIGS. 4 to 8 ), the detection port 221a is connected to the vibration cavity 211 through the connecting cavity 6. According to the method in the first embodiment of the nose pad 100 described above, the vibration cavity 211 and the detection port 221a on the MEMS module 22 must be arranged opposite to each other on the first side 111 and the second side 112 of the first support portion 11. The position setting is not flexible and may be inapplicable. Therefore, other embodiments are also provided in the present application, specifically including the second to sixth embodiments of the nose pad 100 (see FIGS. 4 to 8 ), in which the connecting cavity 6 is arranged between the vibration cavity 211 of the vibration module 21 and the detection port 221a of the MEMS module 22. , in order to connect the two, the connecting cavity 6 only needs to cover the opening of the vibration module 21 and the detection port 221a of the MEMS module 22, so as to connect the vibration cavity 211 in the vibration module 21 with the detection port 221a on the MEMS module 22. There is no need for precise alignment, and the assembly is simple. The setting of the connecting cavity 6 is relatively free, and there is no need to limit the relative position between the vibration module 21 and the MEMS module 22, which can be convenient for specific setting. At the same time, the structural design is simple, easy to design and manufacture, can meet various structural forms, and is more applicable. It can be understood that, similar to the above-mentioned connection method of directly connecting the detection port 221a on the MEMS module 22 and the vibration cavity 211 through the connecting hole 113 opened on the first supporting part 11, so as to directly connect the vibration cavity 211 and the detection port 221a, the method of connecting the detection port 221a and the vibration cavity 211 through the connecting cavity 6 in this embodiment can also be a completely closed structure or a common docking structure. Based on the same recognition as above, the connecting cavity 6 in this embodiment connects the vibration cavity 211 and the detection port 221a to form a closed cavity, thereby improving the effect of isolating external interference and achieving better sound reception effect. The air vibration is transmitted to be recognized by the MEMS module 22, so that the generation and detection and recognition of the air vibration are all in the connecting structure between the detection port 221a and the vibration cavity 211, and the external wind noise and high noise cannot affect it. Moreover, the air vibration is generated by the vibration module 21 receiving the user's voice vibration, and it is related to the user's voice signal. In this way, the MEMS module 22 can detect and recognize the user's voice signal, and avoid the detection and recognition of environmental wind noise and environmental noise, which greatly reduces the influence of environmental wind noise and environmental noise on the pickup of user voice signals, so that the smart glasses 1000 can effectively extract the user's voice signal in a complex noise environment and meet the use requirements in complex environments. Based on this, the vibration module 21 described in the present application mainly utilizes bone conduction to receive the user's pronunciation vibration. Since the position of the nose pad 100 is better for the human bone vibration when speaking, the bone conduction vibration perception of the vibration module 21 arranged on the nose pad 100 is also better, and can generate a high-sensitivity, high-signal-to-noise ratio voice vibration signal, so as to greatly improve the quality of the acquired voice signal, achieve a good call noise reduction effect, and a high wake-up rate and high recognition rate voice wake-up / recognition effect. It should be noted that the vibration module 21 and the MEMS module 22 arranged on the first support part 11 are arranged independently of each other, and can ensure that the detection port 221a is stably connected with the vibration cavity 211, so there are multiple ways of connection, so the positional relationship between the vibration module 21 and the MEMS module 22 does not need to be limited, and the corresponding connection method is set to connect the vibration module 21 and the MEMS module 22 to meet the above-mentioned stable connection requirements. In this application, the vibration module 21 and the MEMS module 22 are arranged on two side surfaces of the first support part 11, that is, the first side 111 surface and the second side 112 surface. In addition, the MEMS (micro-electromechanical system) microphone is used in this application, and its structure volume is smaller, so as to reduce the structure volume of the bone conduction component 2, and it is convenient to be set on the smaller nose pad 100 structure, and the sensitivity of the MEMS (micro-electromechanical system) microphone is more stable, not easily affected by the environment, and more practical. Specifically, in the first embodiment of the nose pad 100 (see FIG. 3 ), the first supporting portion 11 is provided with a connecting hole 113 penetrating the first side 111 and the second side 112 thereof; the vibration cavity 211 is connected to one end of the connecting hole 113, and the detection port 221a is connected to the other end of the connecting hole 113, so that the detection port 221a is connected to the vibration cavity 211. The vibration cavity 211 and the MEMS module 22 are respectively arranged on both sides of the first supporting portion 11. In this embodiment, in order to shorten the communication path between the two as much as possible, the connecting hole 113 is opened on the first supporting portion 11, and the vibration cavity 211 and the detection port 221a of the MEMS module 22 are connected via the connecting hole. Or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model. With the increasing development of computers, electronic technology, and network application technology, electronic devices such as smart glasses are gradually entering people's lives. At present, smart wearable devices such as smart audio glasses, AR / VR, etc. all have functions such as calls, voice wake-up / recognition, etc. Due to the trend of thin and light smart wearable devices, the scene requirements are becoming more and more diverse. In outdoor and industrial scenes, due to the influence of wind noise and high noise (environmental noise), the voice signal picked up by the microphone is easily submerged by strong wind noise and strong environmental noise. Even after being processed by the noise reduction algorithm, the voice signal cannot be effectively extracted, resulting in unsatisfactory call and voice wake-up / recognition effects, or even unable to be used normally. Therefore, a voice recognition structure is urgently needed to solve the above problems. In view of this, the present invention provides a nose pad. FIG. 1 to FIG. 9 are embodiments of the nose pad provided by the present invention. The nose pad will be described below in conjunction with specific drawings. Please refer to FIG. 1 to FIG. 9 , the nose pad 100 is used for smart glasses 1000, wherein: The nose pad 100 includes a support member 1 and a bone conduction component 2. The support member 1 includes two support parts for being placed on both sides of the nose, one of which is a first support part 11, and the first support part 11 has a first side 111 and a second side 112 opposite to each other; the bone conduction component 2 includes a vibration module 21 and a MEMS module 22, the vibration module 21 is arranged on the first side 111 of the first support part 11, and the MEMS module 22 is arranged on the second side 112 of the first support part 11, the vibration module 21 has a vibration cavity 211, and the MEMS module 22 has a detection port 221a, and the detection port 221a is connected to the vibration cavity 211. The vibration module 21 is used to pick up the vibration of the user when speaking, so as to vibrate the air in the vibration cavity 211, and the MEMS module 22 is used to pick up the vibration signal of the user's voice through the vibrating air in the vibration cavity 211, and feed the vibration signal back to the control device on the smart glasses 1000. In the technical solution of the utility model, in order to avoid the influence of environmental wind noise and environmental noise on the smart glasses 1000 picking up the user voice signal, the detection port 221a of the MEMS module 22 is connected with the vibration cavity 211 of the vibration module 21, and the vibration module 21 receives the user's pronunciation vibration and generates corresponding air flow inside the vibration cavity 211 to convert the structural vibration into air vibration. The air vibration is transmitted through the connection between the detection port 221a and the vibration cavity 211.
