[0056] With the increasing development of computers, electronic technology, and network application technology, electronic devices such as smart glasses are gradually entering people's lives.

[0057] 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 use in increasingly diverse scenarios is increasing. However, in outdoor and industrial settings, voice signals picked up by microphones are easily overwhelmed by strong wind noise, high ambient noise (environmental noise), and hair noise. 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. Therefore, a voice recognition architecture is urgently needed to address these issues.

[0058] In view of this, the present invention provides a nose pad. FIG1 to FIG15 are embodiments of the nose pad provided by the present invention. The nose pad will be described below with reference to specific drawings.

[0059] Please refer to Figures 1 to 15. 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 11 for being placed on both sides of the nose; the bone conduction component 2 includes a shell 21, a vibration module 22 and a vibration pickup module 23. The shell 21 is installed on one of the support parts 11. A vibration cavity 211 and a detection cavity 212 that are at least partially connected are formed in the shell 21. The vibration module 22 is used to pick up vibrations when the user speaks, so as to vibrate the air in the vibration cavity 211. The vibration pickup module 23 is used to pick up the vibration signal of the user's voice through the vibrating air in the vibration cavity 211, and transmit the vibration signal to the control device 300 on the smart glasses 1000 via wired or wireless communication.

[0060] 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's voice signal, the inner cavity of the shell 21 is separated to form the vibration cavity 211 and the detection cavity 212, and the vibration module 22 is set to vibrate when picking up the user's voice to vibrate the air in the vibration cavity 211, and the vibration pickup module 23 is used to pick up the vibration signal of the user's voice through the vibrating air in the vibration cavity 211, and feed back the recognized vibration signal to the control device 300 on the smart glasses 1000. In this way, the generation and detection of the sound vibration are both in The vibration cavity 211 and the detection cavity 212 connected in the shell 21 cannot be affected by external wind noise and high noise, and the sound wave is generated by the vibration module 22 receiving the user's voice vibration, which is associated with the user's voice signal. In this way, the vibration signal picked up by the vibration pickup module 23 can be processed to obtain the user's voice signal, and it avoids its detection and identification of environmental wind noise and environmental noise, greatly reducing 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, meeting the use requirements of complex environments. Based on this, the vibration module 22 in the shell 21 described in this application mainly uses bone conduction to receive the user's pronunciation vibration. Since the position of the nose pad 100 is better for the vibration of human bones when speaking, the bone conduction vibration perception of the vibration module 22 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.

[0061] It can be understood that the vibration module 22 and the vibration pickup module 23 can be separately arranged in different structures to perform a split design. For example, an independent vibration module 22 and a vibration pickup module 23 are arranged on the support portion 11, the vibration cavity 211 is arranged in the vibration module 22, and the detection cavity 212 is arranged in the vibration pickup module 23. The vibration cavity 211 and the detection cavity 212 on the independent vibration module 22 and the vibration pickup module 23 are sealed and connected through a connecting structure, which can also achieve the above-mentioned main functions. In this application, it is mainly proposed to connect the vibration module 22 to the vibration pickup module 23. The block 22 and the vibration pickup module 23 are arranged in an integral structure, that is, the vibration cavity 211 and the detection cavity 212 are formed by enclosing the shell 21, and then the vibration module 22 and the vibration pickup module 23 are arranged corresponding to the vibration cavity 211 and the detection cavity 212. On the one hand, the bone conduction component 2 is arranged as a whole, which is convenient for its installation on the support part 11. On the other hand, the vibration cavity 211 and the detection cavity 212 are separated by the cavity enclosed by the shell 21, and there is no need to set a connecting structure between them. The structure is simple and the degree of sealing is better. It should be noted that, on both sides of the support part 11, one side is used to be close to the user's nose, and the other side is away from the user's nose. The bone conduction component 2 can be set on any side thereof, but the bone conduction component 2 is set on the side of the support part 11 close to the user's nose, so that the bone conduction component 2 is close to the vibration source to reduce the loss of vibration on the support part 11, and directly act on the bone conduction component 2, so that the vibration module 22 vibrates more accurately with the user's voice, thereby improving the vibration pickup accuracy, and then improving the accuracy of sound recognition and acquisition.

[0062] Specifically, a partition 215 is provided in the shell 21, and the partition 215 partitions the shell 21 into the vibration cavity 211 and the detection cavity 212; a connecting hole 213 is provided on the partition 215 for connecting the vibration cavity 211 and the detection cavity 212. The vibration cavity 211 and the detection cavity 212 in the shell 21 can be formed as parts of an integral inner cavity, that is, a cavity is formed in the shell 21, and the part close to the vibration module 22 is set as the vibration cavity 211, and the part close to the vibration pickup module 23 is set as the detection cavity 212. However, such a setting, on the one hand, the integrally formed cavity is not easy to adjust the local structure, that is, the vibration module 22 and the vibration pickup module 23 need to be adaptively set, and there are restrictions on the size and shape of the vibration module 22 and the vibration pickup module 23. On the other hand, the cavity is inversely adapted to the vibration modules 22 and the vibration pickup modules 23 of different sizes and shapes. The dynamic pickup module 23 may cause difficulties in structural molding. Therefore, in the present application, the spacer 215 is provided in the shell 21 to independently form the vibration cavity 211 and the detection cavity 212 on both sides of the spacer 215, so as to facilitate the molding of the related structures of the vibration cavity 211 and the detection cavity 212 and to adaptably adjust them independently. The vibration cavity 211 and the detection cavity 212 are then connected by the connecting hole 213 provided in the spacer 215. Without affecting the sealed connection between the vibration cavity 211 and the detection cavity 212, the shell 21 is facilitated to be molded as a whole, thereby reducing the difficulty of production and manufacturing, thereby reducing the design and manufacturing costs.

[0063] Specifically, the vibration module 22 includes a diaphragm 221 disposed in the vibration cavity 211. The vibration module 22 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 22 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 providing the diaphragm 221 in the vibration cavity 211 is mainly adopted. The solution is more mature in the acoustic structure, so as to make it more stable.

[0064] Furthermore, a connecting hole 213 is provided between the vibration cavity 211 and the detection cavity 212, and one side of the diaphragm 221 is provided corresponding to the connecting hole 213. The vibration module 22 also includes a mass block 222 provided on the diaphragm 221. The connecting hole 213 provided between the vibration cavity 211 and the detection cavity 212 has been described above and will not be repeated here. However, the structure of the diaphragm 221 has better vibration effects on both sides of the vibration direction. Therefore, in this application, one side of the diaphragm 221 is provided corresponding to the connecting hole 213 to improve the quality of vibration signal transmission. In addition, the diaphragm 221 generally has a light structure, resulting in a small inertia. When the shell 21 vibrates with the user's nose, the diaphragm 221 cannot move 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. Therefore, the present application sets the mass block 222 on the diaphragm 221 to improve the above situation without affecting the function of the diaphragm 221 to drive the air flow fluctuations in the vibration cavity 211. In addition, it is understandable that the diaphragm 221 can serve as the cavity wall of the vibration cavity 211 to enclose the vibration cavity 211 with the shell 21, but its vibration direction is bidirectional. Even if it is set in this way, a 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 221 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 221 is built into the vibration cavity 211, which also has a certain protective effect. Considering the assembly of the diaphragm 221, the present application sets the shell 21 in a split manner, setting the diaphragm 221 to cover the main part of the shell 21, and then the protective cover structure formed by another part of the shell 21 is set on the main part of the shell 21 to enclose the vibration cavity 211. This facilitates the installation of the diaphragm 221 and meets the structural requirements of the diaphragm 221 being located in the vibration cavity 211.

[0065] In addition, the shell 21 has a vibration end, and the vibration cavity 211 is formed at the vibration end. The vibration end is exposed on the inner side of the support part 11 so as to be in contact with the user's nose. The above mainly describes the technical characteristics and effects of "setting the bone conduction component 2 on the side of the support part 11 close to the user's nose, so that the bone conduction component 2 is close to the vibration source, so as to reduce the loss of vibration on the support part 11, directly act on the bone conduction component 2, so that the vibration module 22 vibrates more accurately with the user's voice, so as to improve the vibration pickup accuracy, and then improve the accuracy of sound recognition and acquisition". Specifically, it is mainly to ensure that the vibration cavity 211 located at the vibration end is as close to the vibration source as possible, that is, close to the user's nose. In this application, the vibration end is exposed on the inner side of the support part 11 so as to be in contact with the user's nose to meet the above requirements. On this basis, the bone conduction component 2 can be directly arranged on the inner side of the support part 11, or it can be passed through the support part 11, with only the vibration end exposed on the inner side of the support part 11. There is no limitation here, and the actual structural design shall prevail.

[0066] In addition, the support portion 11 is provided with a flexible shell 4 that is sleeved on the support member 1, and the vibration end is at least partially located in the flexible shell 4. The nose pad 100 is mainly used to contact and support the user's nose to support the smart glasses 1000 as a whole. Therefore, the nose pad 100 is in direct contact with the user's nose and applies a certain weight pressure to the user's nose. In order to improve the user's comfort, the support portion 11 is covered with the flexible shell 4, and the flexible shell 4 covers the support member 1 and contacts the user's nose to improve wearing comfort. The flexible setting of the flexible shell 4 also further improves the user's wearing comfort. Furthermore, based on the structural feature requirements of the vibration end in contact with the user's nose and the structural function requirements of the flexible shell 4, the present application sets at least a portion of the vibration end in the flexible shell 4 to balance the functional requirements of the two.

[0067] In addition, the vibration pickup module 23 includes a MEMS microphone. Compared to other microphones such as traditional ECM (electret capacitor) microphones, the MEMS (micro-electromechanical system) microphone used in this application has a smaller structure and volume, thereby reducing the structural volume of the bone conduction component 2 and facilitating installation on the smaller nose pad 100 structure. In addition, the sensitivity of the MEMS (micro-electromechanical system) microphone is more stable and less susceptible to changes in environmental influences, making it more practical.

[0068] Specifically, a connecting hole 213 is provided between the vibration cavity 211 and the detection cavity 212; the vibration pickup module 23 includes a vibration diaphragm 231, and the vibration diaphragm 231 is provided corresponding to the connecting hole 213, so as to be vibrated by the air so as to cause the vibration pickup module 23 to produce changes in electrical parameters. The setting of the connecting hole 213 between the vibration cavity 211 and the detection cavity 212 has been described in detail above and will not be repeated here. The vibration pickup module 23 includes the vibration diaphragm 231, which is similar in structure to the vibration membrane 221. The vibration diaphragm 231 structure is provided at a position of the detection cavity 212 corresponding to the connecting hole 213, so as to efficiently receive the vibration signal emitted by the vibration membrane 221 through the connecting hole 213. It should be noted that, in addition to the vibration diaphragm 231, the vibration pickup module 23 is also provided with a signal processor 232 to amplify and filter the electrical parameters generated at the vibration diaphragm 231 and then transmit them to the control device 300 on the smart glasses 1000 for subsequent processing.

[0069] Specifically, an annular sealing portion 216 is provided at one end of the connecting hole 213, and the vibrating diaphragm 231 is provided to cover the annular sealing portion 216. The vibrating diaphragm 231 can be directly set to a position covering the connecting hole 213 in the detection cavity 212 to directly receive the vibration signal transmitted by the diaphragm 221, but such a setting is not convenient for the positioning and installation of the vibrating diaphragm 231, and may cause a gap between the vibrating diaphragm 231 and the connecting hole 213, affecting the vibration signal pickup of the vibrating diaphragm 231, and further affecting the quality of the later output sound signal. Therefore, in the present application, the annular sealing portion 216 is provided at the connecting hole 213, and the annular sealing portion 216 protrudes from the spacer 215. In this way, the vibrating diaphragm 231 only needs to cover the annular sealing portion 216 to ensure its sealed installation, so as to avoid the above-mentioned problems.

[0070] In addition, the nose pad 100 further includes a connecting portion 5, which is used to be detachably connected to the smart glasses 1000 to achieve detachability of the nose pad 100. Obviously, the nose pad 100 and the smart glasses 1000 can be connected via wired or wireless communication.

[0071] Furthermore, in one embodiment, the connecting portion 5 has a built-in accommodating cavity 51, and one end of the connecting portion 5 is provided with a first slot 52 communicating with the accommodating cavity 51, the support member 1 is inserted into the first slot 52, and a contact terminal 53 is provided on one side of the connecting portion 5. One end of the contact terminal 53 located in the accommodating cavity 51 is electrically connected to the vibration pickup module 23, and the other end of the contact terminal 53 extends out of the accommodating cavity 51 and is detachably electrically connected to the smart glasses 1000. The nose pad 100 structure can be integrally formed with the smart glasses 1000, but considering that the nose pad 100 is provided with electronic components and may require subsequent maintenance, repair, and replacement, in this application, the nose pad 100 is configured to be detachably connected to the smart glasses 1000, and the connecting portion 5 for detachably connecting to the smart glasses 1000 is configured as an independent detachable structure. Specifically, the nose pad 100 is provided with the connecting portion 5 for detachably connecting to the smart glasses 1000, and the accommodating cavity 51 is provided in the connecting portion 5, and the first slot 52 connected to the accommodating cavity 51 is opened on one side of the connecting portion 5, so that the support member 1 can be inserted into the accommodating cavity 51 from the first slot 52, or removed from the accommodating cavity 51 from the first slot 52, so as to realize the detachable connection between the connecting portion 5 and the support member 1, which is convenient for later maintenance and disassembly. In particular, the contact terminal 53 is provided on the connecting portion 5. When an abnormality occurs in the electrical connection between it and the vibration pickup module 23 in the bone conduction component 2, the bone conduction component 2 and the contact terminal 53 can be separated by removing the support member 1, which is convenient for maintenance and repair. It should be noted here that the detachable connection method between the connecting part 5 and the support member 1 can be set in a variety of ways, including but not limited to connection through an additional connecting structure, magnetic connection by setting a magnetic structure between the two, etc. In this embodiment, the support member 1 is inserted into the accommodating cavity 51 from the first slot 52. On the one hand, it is convenient for the positioning and docking of the support member 1 and the connecting part 5. On the other hand, the support member 1 is partially inserted into the accommodating cavity 51, so that the connection between the connecting part 5 and the support member 1 is more stable. On the other hand, considering that the structure on the support member 1 needs to be electrically connected to the structure on the smart glasses 1000, the contact terminal 53 is set on the connecting part 5 here, so that the connection between the contact terminal 53 and the vibration pickup module 23 is located in the accommodating cavity 51, which plays a protective role for the electrical connection structure.Of course, the electrical connection structure derived from the vibration pickup module 23 can also be directly positioned and fixed on the surface of the connecting part 5. However, with such an arrangement, on the one hand, the connection between it and the connecting part 5 is located on the end face of the connecting part 5 and has no structural protection. On the other hand, its electrical connection structure needs to be positioned and installed on the connecting part 5 by itself to correspond to the connection contacts on the smart glasses 1000. The operation is complicated and the accuracy is poor. Therefore, this application directly adopts the structure of the preset contact terminal 53 to connect with the electrical connection structure derived from the vibration pickup module 23 in the accommodating cavity 51 to avoid the above problems.

[0072] Specifically, a circuit board 3 is also attached to the support portion 11. The vibration pickup module 23 is electrically connected to one end of the circuit board 3, and the other end of the circuit board 3 extends from the first slot 52 into the accommodating cavity 51 to be electrically connected to the contact terminal 53. With this arrangement, one end of the circuit board 3 is electrically connected to the bone conduction component 2, while the other end is inserted into the accommodating cavity 51 from the first slot 52 and connected to the contact terminal 53. By inserting the circuit board 3 from the first slot 52 into the accommodating cavity 51 and connecting with the contact terminal 53, the circuit board 3 and the support member 1 can be simultaneously inserted into the accommodating cavity 51. That is, a single installation action can simultaneously achieve the structural connection between the support member 1 and the connecting portion 5 and the electrical connection between the circuit board 3 and the contact terminal 53, thereby improving assembly convenience.

[0073] It should be noted that the vibration pickup module 23 needs to be electrically connected to the control device 300 on the smart glasses 1000 through an electrical connection structure. The electrical connection structure can be a connecting line structure, that is, the vibration pickup module 23 located on the support part 11 is connected to the control device 300 on the smart glasses 1000 through the connecting line structure. In this application, the circuit board 3 is attached to the support part 11, and the vibration pickup module 23 is electrically connected to the circuit board 3, so as to be connected to the control device 300 of the smart glasses 1000 through the circuit board 3. The circuit board 3 is easy to be fixed on the support part 11 and is firmly installed.

[0074] Furthermore, a groove 531 is provided at one end of the contact terminal 53 located in the accommodating cavity 51, and a spring piece 31 is protruded at the corresponding position of the circuit board 3. The spring piece 31 extends into the groove 531 to be electrically connected with the contact terminal 53. The insertion of the circuit board 3 from the first slot 52 into the accommodating cavity 51 has been described above. At this time, the circuit board 3 and the contact terminal 53 are in contact and electrically connected, which has poor stability. Therefore, in this embodiment, the groove 531 is provided at one end of the contact terminal 53 located in the accommodating cavity 51, and the spring piece 31 is provided at the corresponding position of the circuit board 3, so that when the circuit board 3 is inserted along the first slot 52, the spring piece 31 first contacts the edge of the contact terminal 53. At this time, if the circuit board 3 is continued to be inserted, the spring piece 31 is deformed by the contact terminal 53 until it is attached to the end face of the circuit board 3, so that the spring piece 31 can pass over the edge of the contact terminal 53 until the spring piece 31 passes over the edge of the contact terminal 53 and reaches the groove 531. The spring piece 31's own elastic force drives it to recover and extend into the groove 531. In this way, on the one hand, the spring piece 31 can abut against the side wall of the groove 531, to a certain extent limit the movement of the circuit board 3 relative to the contact terminal 53, and ensure the stability of its contact positioning. On the other hand, the spring piece 31 extends into the groove 531, which increases the contact area between the circuit board 3 and the contact terminal 53. In summary, the setting of the groove 531 and the spring piece 31 improves the stability of the connection between the two.

[0075] In addition, a limiting groove 521 is provided in the groove wall of the first slot 52, and a clamping portion 12 adapted to the limiting groove 521 is provided at a corresponding position on one side of the support member 1. A protrusion 13 is also provided on the other side of the support member 1, and the protrusion 13 abuts against the other groove wall of the first slot 52 to limit the clamping portion 12 from escaping from the limiting groove 521. When the support member 1 is inserted into the connecting portion 5 from the first slot 52, the stable connection between the support member 1 and the connecting portion 5 cannot be guaranteed by structural restrictions and friction alone. Therefore, in this embodiment, the limiting groove 521 is provided in the groove wall of the first slot 52, and the clamping portion 12 is protruding from the support member 1. With such a configuration, the size of the first slot 52 must meet the size of the support member 1 plus the size of the clamping portion 12, that is, in this embodiment, the width of the first slot 52 must not be less than the thickness of the clamping portion 12 on the support member 1, so that the support member 1 can be inserted from the first slot 52. During the process of inserting the support member 1 into the first slot 52, when the holding portion 12 moves to the limiting slot 521, the holding portion 12 can extend into the limiting slot 521 to limit the support member 1 from extending into or out of the first slot 52. At this time, in order to ensure that the holding portion 12 can be stably maintained in the limiting slot 521, the support member 1 is provided with the protrusion 13 on the side facing away from the holding portion 12. The protrusion 13 is abutted against the other slot wall of the limiting slot 521 to lift the support member 1 so that the holding portion 12 can be stably maintained in the limiting slot 521, thereby limiting the support member 1. The holding portion 12 provided on the support member 1 here can actually also be set to a structure like the spring piece 31 on the circuit board 3, which can deform itself to avoid the first slot 52 without setting the width of the first slot 52 larger, and thus there is no need to set the protrusion to lift the support member 1 in the wider first slot 52, so that the holding portion 12 is maintained in the limiting groove 521 to meet the above functional requirements. However, the structural strength of the support member 1 is actually greater than that of the circuit board 3, and its elasticity is poor, and it is not suitable for processing and forming a structure similar to the spring piece 31. Therefore, in this embodiment, the edge of the support member 1 is bent to form a hook structure as the holding portion 12 to extend into the limiting groove 521, which facilitates the processing of the support member 1 structure and meets the above structural functional requirements.

[0076] Furthermore, the connecting portion 5 includes a connecting base 54 and a cover plate 55. The cover plate 55 is disposed on the connecting base 54 to enclose the accommodating cavity 51. One end of the connecting base 54 defines a first slot 52 that communicates with the accommodating cavity 51. The contact terminal 53 is disposed through one side of the connecting base 54. To further achieve the beneficial effect of a detachable structure that facilitates installation, maintenance, and repair, in this embodiment, the connecting portion 5 is configured with a detachable connecting base 54 and cover plate 55. This allows for maintenance and inspection of various locations within the accommodating cavity 51 when the cover plate 55 is removed from the connecting base 54, facilitating operations such as maintenance and replacement of the contact terminal 53.

[0077] Furthermore, a fixing structure 56 is provided between the connecting seat 54 and the cover plate 55, and the fixing structure 56 includes a connecting structure 562 provided at one end of the connecting seat 54 and a second slot 561 opened on the inner wall of the connecting seat 54. One end of the cover plate 55 is inserted into the second slot 561, and the other end is fixed to the connecting seat 54 through the connecting structure 562. Based on the detachable arrangement of the connecting seat 54 and the cover plate 55, an additional fixing structure 56 needs to be provided between the connecting seat 54 and the cover plate 55 to securely connect the two. It can be understood that setting the fixing structure 56 as a multi-point screw connection structure can make the connection between the connecting seat 54 and the cover plate 55 stable, and the screw connection structure is relatively mature, with low part cost and simple structure, but it requires multi-point threaded connection, which is cumbersome to operate. Therefore, in this embodiment, a second slot 561 is provided at one end of the connecting seat 54, so that one end of the cover plate 55 can be inserted into the second slot 561, and the other end of the cover plate 55 is connected to the connecting seat 54 through the connecting structure 562 to ensure the stability of the connection between the two, and the operation is relatively simple. And different installation and disassembly effects can be obtained for different connecting structures 562. Specifically, the connecting structure 562 in this embodiment can be the above-mentioned screw connecting structure 562 (see Figures 4 to 8), which has the above-mentioned beneficial effects, but avoids the tedious operation of the above-mentioned multi-point threaded connection, ensuring the stability of the connection while facilitating installation and disassembly operations. Furthermore, the connecting structure 562 can also be set as a snap-fit ​​connecting structure 562 (see Figures 9 to 14), so that when installing the cover plate 55, only one end of it needs to be inserted into the second slot 561, and then the other end needs to be forcefully inserted into the snap-fit ​​connecting structure 562, which is easier to operate. However, relatively speaking, its structural stability is worse than that of the above-mentioned screw connecting structure 562. However, in this embodiment, it can meet the usage requirements.

[0078] Furthermore, a locking protrusion 551 is provided on the side of the cover plate 55 facing away from the accommodating cavity 51, and the locking protrusion 551 is used to lock with the smart glasses 1000. According to the structure of the connecting portion 5, it is also inserted into the smart glasses 1000 by inserting the connection method to achieve structural connection, similar to the insertion of the support member 1 into the first slot 52. Therefore, the insertion structure and friction alone cannot ensure the stability of the connection. Therefore, in this embodiment, the locking protrusion 551 is provided on the outer side of the cover plate 55 to enable it to lock with the locking hole on the smart glasses 1000, thereby improving the stability of the connection of the connecting portion 5 to the smart glasses 1000.

[0079] In addition, the support member 1 is provided with a flexible shell 4 that is sleeved on the support portion 11. The flexible shell 4 abuts against the end surface of one end of the connecting portion 5, and a third slot 41 is provided on one side between the flexible shell 4 and the connecting portion 5 at the abutment point, and a plug-in portion 541 is provided on the other side. The plug-in portion 541 is inserted into the third slot 41. On the basis that the support member 1 is inserted into the first slot 52 to position and connect the connecting portion 5, a plug-in structure is further provided between the flexible shell 4 and the connecting portion 5 to further improve its positioning performance and connection stability. Specifically, based on the first slot 52 being provided on the connecting portion 5, the plug-in portion 541 is provided on the end surface of the connecting portion 5, and the third slot 41 is provided on the flexible shell 4, so that the plug-in portion 541 and the third slot 41, and the support member 1 and the first slot 52 are cross-plugged, thereby ensuring the stability of the connection between the support member 1 and the connecting portion 5.

[0080] Referring to FIG16 , the present invention further provides a pair of smart glasses 1000, comprising a frame 200 and a nose pad 100. The frame 200 comprises a frame 201 and temples 202 located on either side of the frame 201, with a control device 300 disposed on the temples 202. The support member 1 of the nose pad 100 is detachably mounted on the frame 201 or integrally formed with the frame 201, and the vibration pickup module 23 within the nose pad 100 is electrically connected to the control device 300 via a wired or wireless connection. The specific structure of the nose pad 100 is described with reference to the above-described embodiments. Since the smart glasses 1000 utilize all the technical solutions of all the above-described embodiments, they at least possess all the beneficial effects brought about by the technical solutions of the above-described embodiments, which will not be further elaborated herein.

[0081] In addition, a sound collection device 400 is provided on the temple 202, and the sound collection device 400 is electrically connected to the control device 300 via a wired or wireless connection. In addition to the bone conduction component 2 provided on the nose pad 100 to pick up sound through the user's nasal vibrations, this application also adds the sound collection device 400 to the temple 202 to collect the sound emitted by the user to the external environment. Therefore, the sound collection device 400 and the bone conduction component 2 have similar functions, both of which collect the user's voice to meet the smart glasses 1000's functions that are realized through sound, such as calls, voice wake-up / recognition, etc. Therefore, both can be activated independently, that is, one can be activated selectively. When both are activated synchronously, as shown in Figure 17 , the sound collection device 400 picks up voice signals transmitted by air vibrations, while the bone conduction component 2 picks up voice signals transmitted by bone vibrations. The control device 300 of the smart glasses 1000 also includes a processing module, which is connected to the sound collection device 400 and the bone conduction component 2 (specifically, the vibration pickup module 23) via wired or wireless communication. This processing module is used to perform fusion and noise reduction processing based on the vibration signals picked up by the sound collection device 400 and the bone conduction component 2. In addition to voice signals, air also contains various noises, such as wind noise and sounds from other objects. However, the bone conduction component 2 only picks up the vibration signals of the user speaking, shielding other airborne signals. Therefore, the signals from the sound collection device 400 and the bone conduction component 2 can be fused together, resulting in clear voice noise reduction. Specifically, the vibration voice signal picked up by the bone conduction component 2 and the ambient voice signal collected by the sound collection device 400 undergo signal amplification and filtering. An algorithm then fuses the two acquired voice signals, filtering out wind noise and specific noises for various applications. After noise reduction processing, the voice signal is transmitted with high clarity and a high signal-to-noise ratio. Furthermore, the smart glasses 1000 are equipped with a speaker for outputting the collected voice signal or other sound signals, complementing the functionality of the smart glasses 1000.
