[0047] With the increasing development of computers, electronic technology, and network application technology, electronic devices such as smart glasses are gradually entering people's lives.

[0048] 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.

[0049] In view of this, the present invention provides a nose pad. FIG1 to FIG5 are embodiments of the nose pad provided by the present invention. The nose pad will be described below with reference to specific drawings.

[0050] Please refer to Figures 1 to 5. 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 a first support portion 11; the bone conduction component 2 includes a vibration module 21 and a MEMS module 22. The vibration module 21 and the MEMS module 22 are both provided on the first support portion 11. The vibration module 21 has a vibration cavity 211. The vibration module 21 includes a vibration member (including a diaphragm 212 and a mass block 213) and a vibration cavity 211. The vibration member divides the vibration cavity 211 into two parts. The vibration cavity 211 has a vibration cavity 211 with the vibration member. The first end wall 211a and the second end wall 211b are opposite to each other, and the distance between the vibrator and the first end wall 211a and / or the distance between the vibrator and the second end wall 211b is greater than the maximum amplitude of the vibrator. 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. 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.

[0051] 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.

[0052] Furthermore, the distance between the vibrating member and the first end wall 211a and / or the distance between the vibrating member and the second end wall 211b is greater than the maximum amplitude of the vibrating member, so as to provide the vibrating member with a sufficiently large vibration space to prevent the vibrating member from colliding with the first end wall 211a and / or the second end wall 211b during vibration.

[0053] It should be noted that the vibration module 21 and the MEMS module 22 provided on the first support portion 11 are independently provided, 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 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 addition, the MEMS (micro-electromechanical system) microphone used in this application has a smaller structural volume 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.

[0054] In one embodiment, the support member 1 includes two support portions arranged on either side of the nose, one of which is a first support portion 11. The bone conduction component 2 is mounted on at least the first support portion 11, with the bone conduction component 2 positioned proximate to the free end of the first support portion 11. It is understood that when the first support portion 11 is placed on the user's nose, its free end is closer to the user's nasal cavity. When a user speaks, their nasal cavity vibrates more effectively. Therefore, in addition to positioning the bone conduction component 2 on the first support portion 11, the bone conduction component 2 is further positioned proximate to the free end of the first support portion 11 to further enhance the bone conduction vibration perception of the vibration module 21 of the nose pad 100, thereby further improving the quality of the acquired voice signal.

[0055] In addition, referring to FIG3 , which is a first embodiment of the nose pad 100 provided in the present application, the vibration cavity 211 is provided with an exhaust hole 211a, and the detection port 221a of the MEMS module 22 is docked with the exhaust hole 211a, so that the detection port 221a is connected to the vibration cavity 211. It can be understood that the shorter the communication path between the detection port 221a and the vibration cavity 211, the smaller the loss of vibration energy, which can further ensure the quality of the vibration sound signal detected and identified by the MEMS module 22. Therefore, in this embodiment, the vibration module 21 and the MEMS module 22 are arranged on the same side of the first support portion 11, and the vibration module 21 and the MEMS module 22 are abutted, so that the exhaust hole 211a on the vibration cavity 211 is directly docked with the detection port 221a on the MEMS module 22, thereby forming a communication structure with a shorter path and obtaining a higher sound signal quality.

[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, a non-closed structure without considering gaps, etc., as long as the above-mentioned communication channel is stably connected, it 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 is connected to the inner cavity of the MEMS module 22 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 some embodiments of the nose pad 100, the detection port 221a is connected to the vibration cavity 211 through a connecting cavity 6. A method of directly docking the exhaust hole 211a on the vibration cavity 211 with the detection port 221a on the MEMS module 22 can obtain higher sound signal quality. However, during the assembly process of the vibration module 21 and the MEMS module 22, the process accuracy requirements for accurately docking the exhaust hole 211a of the vibration cavity 211 with the detection port 221a of the MEMS module 22 are high, which makes the cost high, and the structure that must be abutted against each other is relatively fixed and inflexible, and there may be situations where it is not applicable. Therefore, other embodiments are also provided in the present application, in which the connecting cavity 6 is provided between the vibration cavity 211 of the vibration module 21 and the detection port 221a of the MEMS module 22 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 to connect the vibration module 21. The vibration cavity 211 inside is connected with the detection port 221a on the MEMS module 22, and does not require precise alignment, so 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 facilitate 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 connection method of directly connecting the exhaust hole 211a opened in the vibration cavity 211 with the detection port 221a on the MEMS module 22, 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, referring to Figure 4, which is a second embodiment of the nose pad 100 given in this application, the first supporting portion 11 is covered with a covering shell 3, the MEMS module 22 and the vibration module 21 are both arranged in the covering shell 3, and the vibration module 21 is provided with an exhaust hole 211a connecting the vibration cavity 211 and the inner cavity of the covering shell 3, and the inner cavity of the covering shell 3 forms the connecting cavity 6. In some embodiments of the nose pad 100, only the covering function of the covering shell 3 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 3 to form the connecting cavity 6. In this embodiment, an inner cavity is provided in the covering shell 3, so that the covering shell 3 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 3, and the connecting cavity 6 connects the exhaust hole 211a of the vibration cavity 211 in the vibration module 21 and the detection port 221a on the MEMS module 22 to achieve communication 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.

[0060] In addition, referring to FIG5 , which is a third embodiment of the nose pad 100 provided in the present application, the first support portion 11 is provided with a connecting hole 111 running through both sides thereof, and the MEMS module 22 and the vibration module 21 are provided on both sides of the first support portion 11, and correspondingly sealed and docked with both ends of the connecting hole 111. Similar to the first embodiment of the nose pad 100 described above, when the MEMS module 22 and the vibration module 21 are provided on both sides of the first support portion 11, in order to shorten the communication path between the two, in this embodiment, the connecting hole 111 is provided on the first support portion 11, and the vibration cavity 211 is connected to the detection port 221a of the MEMS module 22 via the connecting hole 111. In this way, the attenuation of the airflow fluctuation by the communication path is reduced, thereby improving the quality of the acquired voice signal.

[0061] Furthermore, the width of the area corresponding to the first support portion 11 and the vibration cavity 211 is D1, and the width of the communication hole 111 is D2, where D2≥0.1D1, so as to ensure the size of the communication hole 111 for convenient exhaust.

[0062] Specifically, the MEMS module 22 includes a circuit board 222 and an EMS sensor disposed on the circuit board 222. The circuit board 222 covers the communication hole 111, and the detection port 221a is disposed on the circuit board 222 and communicates with the inner cavity of the MEMS sensor. The detection port 221a communicates with the communication hole 111, and the circuit board 222 is sealed and attached to the periphery of the communication hole 111. The MEMS sensor needs to be electrically connected to the control device of the smart glasses 1000 via an electrical connection structure. This electrical connection structure can be a connecting wire structure. Specifically, the MEMS sensor is fixed to the first support portion 11 and then connected to the MEMS sensor via the connecting wire structure to connect to the control device of the smart glasses 1000. However, in this application, the circuit board 222 is attached to the first support portion 11 and the MEMS sensor is patched onto the circuit board 222 to position and secure the MEMS sensor and connect it to the control device of the smart glasses 1000. This method facilitates installation and operation and provides strong stability. It should be noted that in the above scheme, it is necessary to open the connecting hole 111 on the first supporting part 11 so that when the detection port 221a on the MEMS sensor is docked with the connecting hole 111, 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 connecting hole 111.

[0063] Furthermore, in order to ensure the sealing degree of the joint between the MEMS sensor and the connecting hole 111, a sealing ring 4 is provided between the circuit board 222 and the first support part 11 and is arranged around the connecting hole 111 to enclose the connecting hole 111 and the avoidance hole located on the circuit board 222.

[0064] In addition, the vibration module 21 includes a diaphragm 212 arranged 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 and other structures, all of which can achieve similar functions. In this application, the embodiment of setting 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.

[0065] 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.

[0066] Furthermore, the mass block 213 occupies a local area of ​​the diaphragm 212 , so that the diaphragm 212 has an outer ring surrounding the mass block 213 , so that the outer ring maintains the elasticity of the diaphragm 212 to facilitate its vibration deformation.

[0067] Furthermore, the vibration cavity 211 is divided into a first cavity 2111 and a second cavity 2112 by the diaphragm 212, and the mass block 213 is located in the first cavity 2111. The size of the first cavity 2111 in the vibration direction of the vibration member is larger than the size of the second cavity 2112 in the vibration direction of the vibration member, so that the first vibration cavity 2111 provides sufficient vibration space for the mass block 213.

[0068] In one embodiment, the second cavity 2112 is provided with an exhaust hole 211 a communicating with the detection port 221 a to facilitate exhaust.
