[0048] With the increasing development of computers, electronic technology, and network application technology, electronic devices such as smart glasses are gradually entering people's lives.
[0049] 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.
[0050] In view of this, the present invention provides a nose pad. FIG1 to FIG8 are embodiments of the nose pad provided by the present invention. The nose pad will be described below with reference to specific drawings.
[0051] Referring to Figures 1 to 8, the nose pad 100 is used in 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 correspondingly placing 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, both of which are arranged on the first side 111 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, which is connected to the vibration cavity 211. The vibration module 21 is used to pick up vibrations when the user speaks, thereby vibrating the air in the vibration cavity 211, and the MEMS module 22 is used to pick up vibration signals of the user's voice through the vibrating air in the vibration cavity 211, and feed the vibration signals back to the control device on the smart glasses 1000.
[0052] 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 detection port 221a of the MEMS module 22 is connected to 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, that is, into sound waves located in the above-mentioned closed structure. The sound waves propagate through the closed channel and are recognized by the MEMS module 22. In this way, the generation and detection of the air vibration are realized. The recognition is all in the communication structure between the detection port 221a and the vibration cavity 211, and the 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.
[0053] 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 the same side of the first support portion 11, that is, the first side 111, is specifically described. In addition, the present application uses a MEMS (micro-electromechanical system) microphone, which 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] Specifically, 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, when the vibration module 21 and the MEMS module 22 are located on the same side of the first support portion 11, in this embodiment, 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.
[0055] 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.
[0056] In addition, in the second to fifth embodiments of the nose pad 100 (see Figures 4 to 7), the detection port 221a is connected to the vibration cavity 211 through the connecting cavity 8. 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, but in the assembly process of the vibration module 21 and the MEMS module 22, the exhaust hole 211a of the vibration cavity 211 and the detection port 221a of the MEMS module 22 accurately docking requires high process precision, 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 given in this application, specifically including the second to fifth embodiments of the nose pad 100 (see Figures 4 to 7), in which the exhaust hole 211a on the vibration cavity 211 and the detection port 221a on the MEMS module 22 are directly docked. The connecting cavity 8 is set between the vibration cavity 211 and the detection port 221a of the MEMS module 22 to connect the two. The connecting cavity 8 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 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 8 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.
[0057] 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 8 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 8 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.
[0058] Specifically, in the second embodiment of the nose pad 100 (see Figure 4), a sealed shell 3 is further provided on the first side 111 of the first support portion 11, and the sealed shell 3 is located next to the vibration module 21, and together with the vibration module 21 and the first side 111 of the first support portion 11, forms the connecting cavity 8; the side wall of the vibration cavity 211 adjacent to the connecting cavity 8 is provided with an exhaust hole 211a, and the vibration cavity 211 is connected with the connecting cavity 8 through the exhaust hole 211a, and the MEMS module 22 is arranged in the connecting cavity 8, so that the detection port 221a is connected with the vibration cavity 211 through the connecting cavity 8. A sealed shell 3 is provided, one end of which is overlapped with the vibration module 21 and the other end is 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 enclosed to form the connecting cavity 8, and the exhaust hole 211a opened on the vibration cavity 211 is arranged corresponding to the connecting cavity 8. At the same time, the MEMS module 22 is accommodated in the sealed shell 3. In this way, the detection port 221a of the MEMS module 22 is located in the connecting cavity 8, realizing the technical solution of communicating the detection port 221a with the exhaust hole 211a through the connecting cavity 8.
[0059] 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 8 . 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 8. In the third embodiment (see FIG5 ) and the fourth embodiment (see FIG6 ) 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 8, and the vibration module 21 and the MEMS module 22 are placed in the covering shell 4, and the exhaust hole 211a of the vibration cavity 211 in the vibration module 21 and the detection port 221a on the MEMS module 22 are connected by the connecting cavity 8 to achieve the connection between the two. Obviously, this structural setting does not require the addition of additional structures to form the connecting cavity 8, has fewer parts, is convenient for assembly, and reduces costs.
[0060] Specifically, in the third embodiment of the nose pad 100 proposed in this application (see FIG5 ), the vibration module 21 is provided with an exhaust hole 211a at the end facing away from the first support portion 11. The exhaust hole 211a connects the inner cavity of the covering shell 4 with the vibration cavity 211. In the fourth embodiment of the nose pad 100 proposed in this application (see FIG6 ), an exhaust hole 211a is provided through the second side 112 of the first support portion 11, connecting the vibration cavity 211. The exhaust hole 211a connects the inner cavity of the covering shell 4 with the vibration cavity 211. The cavity wall of the vibration cavity 211 of the vibration module 21 can be formed by the first support portion 11. Therefore, the exhaust hole 211a provided in the vibration cavity 211 can be located at the end of the vibration module 21 facing away from the first support portion 11 and at a position on the first support portion 11 corresponding to the vibration cavity 211. Therefore, the six and seventh embodiments proposed in this application provide two different arrangements for the exhaust hole 211a. On this basis, the inner cavity of the covering shell 4 covered on the first supporting part 11 can be freely set, and it only needs to cover the exhaust hole 211a of the vibration cavity 211, and there is no limitation here. Moreover, the position of the detection port 221a on the MEMS module 22 is also not limited, and it can be coordinated with the inner cavity of the covering shell 4 to ensure that the inner cavity of the covering shell 4 covers the detection port 221a of the MEMS module 22, and there is no specific limitation. Finally, it is ensured that the inner cavity of the covering shell 4 forms the connecting cavity 8 to connect the exhaust hole 211a on the vibration cavity 211 in the vibration module 21 and the detection port 221a on the MEMS module 22.
[0061] In addition, a covering shell 5 is provided on the first side 111 of the first support part 11, and the covering shell 5 covers the vibration module 21 and the MEMS module 22. The vibration cavity 211 is provided with an exhaust hole 211a connected to the inner cavity of the covering shell 5. The covering shell 5 and the first side 111 of the first support part 11 together enclose the connecting cavity 8. Similar to the above-mentioned covering shell 4, the covering shell 5 is arranged on the first side 111 of the first support part 11, so that the covering shell 5 and the first support part 11 are enclosed to form the connecting cavity 8, but different from the covering shell 4 in that the covering shell 4 is mainly used to cover the first support part 11 to form a structure that contacts the user's nose and plays a protective role. The secondary function is to set an inner cavity to form the connecting cavity 8. Therefore, the covering shell 4 is set as a flexible shell, and the function of the covering shell 5 is mainly to cover the vibration module 21 and the MEMS module 22 to form the connecting cavity 8. The secondary function is to provide a certain protection for the vibration module 21 and the MEMS module 22, and when a flexible shell is set outside the covering shell 5, it plays a role in supporting and separating the connecting cavity 8. Specifically, please refer to Figure 7, which is the fifth embodiment of the nose pad 100 proposed in this application. The exhaust hole 211a of the vibration cavity 211 can be opened on the side facing away from the first support part 11, or can be opened on the first support part 11 as described above. In this embodiment, it is obvious that the exhaust hole 211a is opened on the end of the vibration module 21 facing away from the first support part 11, which is more convenient for structural setting.
[0062] In addition, the second side 112 of the first support part 11 is penetrated by an exhaust hole 211a connected to the vibration cavity 211, the detection port 221a of the MEMS module 22 is arranged corresponding to the first support part 11, and the second side 112 of the first support part 11 is penetrated by an opening 113 connected to the detection port 221a; the second side 112 of the first support part 11 is also provided with a cover 6, the cover 6 is arranged to cover the exhaust hole 211a and the opening 113, and the cover 6 and the second side 112 of the first support part 11 enclose the connecting cavity 8. In some embodiments of the nose pad 100, the vent 211a is provided on the first support portion 11 at a position corresponding to the vibration cavity 211, and the opening 113 is provided on the first support portion 11 at a position corresponding to the detection port 221a. This allows the connecting cavity 8 to be located on the second side 112 of the first support portion 11, thereby connecting the vent 211a and the opening 113, and thus connecting the vibration cavity 211 and the detection port 221a. This prevents the connecting cavity 8 from being interfered with or restricted by the structures of the vibration module 21 and the MEMS module 22, further facilitating the installation of the connecting cavity 8. Specifically, the vent 211a can be provided only on the first support portion 11, or the opening 113 can be provided only on the first support portion 11. However, due to the structural feature that the vibration cavity 211 and the MEMS module 22 are located on the same side of the first support portion 11, if only one of these options is provided, the connecting cavity 8 must be located around the edge of the first support portion 11, which is obviously more complex and impractical. Therefore, in the sixth embodiment of the nose pad 100 proposed in the present application (see Figure 8), the exhaust hole 211a and the opening 113 are provided on the first supporting portion 11, and the cover 6 is provided on the second side 112 of the first supporting portion 11. The cover 6 covers the exhaust hole 211a and the opening 113, so that the connecting cavity 8 is formed on the second side 112 of the first supporting portion 11. On the one hand, it is convenient for the positioning and installation of the vibration module 21 and the MEMS module 22, and there is no need to continue to install other structures on the first side 111 of the first supporting portion 11 after the vibration module 21 and the MEMS module 22 are installed. On the other hand, it is convenient for the setting of the connecting cavity 8. It is only necessary to provide the cover 6 on the second side 112 of the first supporting portion 11 to cover the exhaust hole 211a and the opening 113 to form the connecting cavity 8 connecting the vibration cavity 211 and the MEMS module 22.Of course, other connection structures can also be provided here. The exhaust hole 211a and the opening 113 can be directly connected by a pipeline structure, or they can be connected by forming a closed cavity covering the exhaust hole 211a and the opening 113 through other structures, as long as the requirement of connecting the exhaust hole 211a and the opening 113 is met.
[0063] 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.
[0064] In addition, the MEMS module 22 includes a MEMS sensor 221 and a circuit board 222, wherein the detection port 221a is provided on the MEMS sensor 221, and the MEMS sensor 221 is electrically connected to the circuit board 222. The MEMS sensor 221 needs to be electrically connected to the control device on the smart glasses 1000 via an electrical connection structure, which can be a connecting wire structure. Specifically, the MEMS sensor 221 is fixed to the first support portion 11, and then connected to the MEMS sensor 221 via the connecting wire structure to connect to the control device on the smart glasses 1000. However, in the present application, the circuit board 222 is attached to the first support portion 11, and the MEMS sensor 221 is patched onto the circuit board 222 to position and fix the MEMS sensor 221 and connect it to the control device of the smart glasses 1000. This facilitates installation and operation and provides strong stability. It should be noted that in the above scheme, it is necessary to open the opening 113 on the first supporting part 11 so that when the detection port 221a on the MEMS sensor 221 is docked with the opening 113, the circuit board 222 should adaptively open an avoidance hole at the corresponding position to meet the docking requirements of the MEMS sensor 221 and the opening 113. 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 supporting part 11, and the sealing gasket can be arranged in a ring shape to enclose the opening 113 and the avoidance hole.
[0065] 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.
[0066] 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.
[0067] 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. The nose pad 100 can be integrally formed with the smart glasses 1000, but considering that the nose pad 100 is equipped with electronic devices and may require subsequent maintenance, repair, and replacement, the present application configures the nose pad 100 to be detachably connected to the smart glasses 1000, and the mounting portion 7 for detachable connection with the smart glasses 1000 is configured as an independent detachable structure.
[0068] Referring to FIG9 , the present invention further provides a pair of smart glasses 1000 , comprising a glasses body 200 and a nose pad 100 . The support member 1 of the nose pad 100 is integrally formed with the glasses body 200 , or the support member 1 of the nose pad 100 is detachably mounted to the glasses body 200 via a mounting portion 7 . The specific structure of the nose pad 100 is described with reference to the aforementioned embodiments. Since the smart glasses 1000 utilize all of the technical solutions of all of the aforementioned embodiments, they possess at least all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be further elaborated here.
[0069] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
