Description

Technical Field

[0001] This application relates to the field of wearable devices, and more specifically, provides a smart glasses temple, smart glasses, and a data acquisition system. Background Technology

[0002] Eyeglasses consist of a frame and temples. For smart glasses with a camera, if the frame and temples are detachable, the camera is typically mounted on the frame, and the circuitry in the frame is electrically connected to the circuitry in the temples.

[0003] In reality, frames and lenses are typically supplied by traditional eyewear manufacturers, while temples are provided by electrical component manufacturers. After receiving the frames, they need to be modified to make them electrically connected to the temples. During the design and iteration process, the electrical connection between the frames and temples needs to be considered, requiring separate circuits for the left and right temples. During testing, both temples need to be connected to the frames, which lengthens the development cycle and affects development and testing costs.

[0004] Some smart glasses feature an integrated frame and temple design, which eliminates the need to consider the electrical connection between the frame and temple. However, it still requires designing the left and right temples and making them electrically connected, resulting in high development and testing costs. Utility Model Content

[0005] In view of this, this application aims to provide a smart glasses temple, smart glasses, and a data acquisition system, so as to shorten the development cycle of smart glasses and reduce development and testing costs without affecting the normal function of smart glasses.

[0006] First, this application provides a smart glasses temple, comprising: a housing with a connector on one side surface for connecting the housing to the frame of the smart glasses; the housing includes a hollow cavity containing a camera, a processor, a storage module, a wireless communication module, and a battery; the camera is connected to the processor and the storage module, and the processor is connected to both the storage module and the wireless communication module; the wireless communication module is connected to both the processor and the storage module; and the battery is connected to the camera, the processor, the storage module, and the wireless communication module.

[0007] In this embodiment, the temple of the smart glasses has a connector on its side, allowing for a detachable connection between the temple and the frame. The camera, processor, storage module, wireless communication module, and battery are all housed within the casing. The camera is located at the temple and focuses on capturing images forward. The connector is located on the side of the temple, and the frame is connected to the side. Therefore, the camera is not obstructed by the frame and can function normally. This allows the smart glasses to function as normal smart glasses after the temple is connected to the frame. This method enables the smart glasses temple to function as smart glasses. Therefore, during development, only the temple needs to be developed, and after development, only the temple and frame need to be mechanically connected, eliminating the need for electrical connections between them. This effectively reduces development difficulty and shortens the development cycle. During testing, even a single temple can be used. If collaborative work between two temples is required, they can be connected via a wireless communication module, eliminating the need for electrical connections. This effectively reduces testing costs.

[0008] In one embodiment, the housing includes a front end and a rear end, the front end being the end closest to the frame; the camera is disposed at the front end.

[0009] In this embodiment, the camera is positioned at the front end, which ensures that the camera is not obstructed in the image acquisition direction, allowing the temples of the smart glasses to also acquire images normally.

[0010] In one embodiment, the upper surface of the housing or the side surface not where the connector is located is provided with a protrusion, and the receiving cavity communicates with the interior of the protrusion; the camera is fixedly disposed on the protrusion and the camera is positioned facing forward.

[0011] The camera has a certain size, while the temples of the glasses are limited in size; otherwise, they would be inconvenient to wear. Therefore, in the embodiments of this application, a protrusion can be provided on the upper surface of the housing, and the camera can be placed inside the protrusion to reduce the limitation of the camera on the size of the temples, without having to make the entire size of the temples larger than the camera. At the same time, it allows the camera to be unobstructed by the frame, temples, or other components, making it possible to use the camera to capture the scene in front of the user.

[0012] In one embodiment, the temple of the smart glasses further includes a speaker, which is disposed within the receiving cavity and connected to the processor and the storage module, respectively.

[0013] In this embodiment, a speaker is provided on the temple of the smart glasses to enable the smart glasses to play audio, to test the audio playback function, and to expand the scope of use of the temple of the smart glasses.

[0014] In one embodiment, the temple of the smart glasses further includes a microphone group disposed within the receiving cavity; the microphone group includes at least one microphone.

[0015] In this embodiment of the application, a microphone is provided in the temple of the glasses, which enables the temple to collect voice, realize the testing of audio collection function, and expand the application range of smart glasses temples.

[0016] In one embodiment, the microphone group includes a first microphone and a second microphone, with the distance between the first microphone and the second microphone being greater than a preset distance; the processor is configured to determine whether the wearer of the smart glasses with the temple is speaking based on the amplitude difference, power difference, or phase difference of the audio signals collected by the first microphone and the second microphone respectively.

[0017] In this embodiment, the distance between the first microphone and the second microphone is greater than a preset distance, which makes the audio signals collected by the first microphone and the second microphone different, forming a differential signal. This allows the temple of the smart glasses to identify whether the wearer is speaking through the differential audio signals collected by different microphones. For example, it can determine whether the wearer of the smart glasses is speaking by using amplitude difference, power difference, or phase difference. By determining whether the wearer is speaking, it is helpful to test functions such as voice noise reduction and sound direction acquisition.

[0018] In one embodiment, the first microphone is disposed above the receiving cavity, and the second microphone is disposed below the receiving cavity.

[0019] In this embodiment, the first microphone and the second microphone are respectively positioned above and below the receiving cavity, which helps to increase the distance between the first microphone and the second microphone and improve the accuracy of wearer speech detection based on the audio signals collected by the two microphones.

[0020] In one embodiment, the angle between the first direction and the second direction is within a preset angle range; the first direction is the direction in which the first microphone points to the second microphone, and the second direction is the direction in which the second microphone points to a preset position, wherein the preset position is used to characterize a preset position of the wearer's mouth.

[0021] In this embodiment, the angle between the first direction and the second direction is within a preset angle range, and the second direction is pointed by the second microphone to represent the position of the wearer's mouth. This method can improve the difference between the sound collected by the first microphone and the second microphone from the direction of the wearer's mouth, and improve the accuracy of the wearer's speech detection.

[0022] Secondly, embodiments of this application provide a smart glasses, including: a first temple and a second temple, wherein the first temple and the second temple are both smart glasses temples as described in any of the first aspects; the first temple and the second temple are wirelessly connected; and a frame connected to the first temple and the second temple.

[0023] Thirdly, embodiments of this application provide a data acquisition system, including: smart glasses as described in the second aspect; and a main device wirelessly connected to at least one of the first temple and the second temple of the smart glasses. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0032] First, this application provides a smart glasses temple 100. The temple includes: a housing, a camera 220, a processor 210, a storage module 230, a wireless communication module 240, and a battery 250.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of a smart glasses temple 100 provided in one embodiment of this application. The outer shell includes opposing front and rear ends. When the smart glasses temple 100 (or simply "temple") is worn, the front end refers to the end closer to the frame, and the rear end is the end farther from the frame. The shape of the outer shell can be referenced from the temple, and will not be elaborated here. Figure 1 This is merely an example and should not be construed as limiting this application.

[0034] like Figure 1 As shown in the embodiments of this application, a connector is provided on one side surface of the outer shell. The connector can be a slot, bolt, magnetic component, or other component, or a corresponding component can be provided on the frame. Through the connector, the temple of the smart glasses 100 can be detachably connected to the connector.

[0035] In the above embodiments, the frame may not have circuitry and may consist of lenses and a lens frame. Components capable of connecting to the temples 100 of the smart glasses are provided on both sides of the frame. In other embodiments, if the frame has circuitry, the connectors may include a mechanical connection 110 and an electrical connection 110. The mechanical connection 110 is used to fix the frame to the temples 100 of the smart glasses, and the electrical connection 110 is used to electrically connect the electrical components between the temples 100 of the smart glasses and the frame. The above are merely examples and should not be construed as limiting the scope of this application.

[0036] In the embodiments of this application, the outer shell includes a hollow receiving cavity 120, and the camera 220, processor 210, storage module 230, wireless communication module 240 and battery 250 are all disposed within the receiving cavity 120.

[0037] The processor 210 can be a CPU (Central Processing Unit), MCU (Microcontroller Unit), etc.; the storage module 230 can include cache, random access memory, etc.; the battery 250 can be a disposable battery or a rechargeable battery; the wireless communication module 240 can be a Bluetooth module, WiFi (Wireless Fidelity) module, etc.; and the camera 220 can be any type of camera, with a size adapted to the smart glasses. The types, structures, and supporting circuits of the above-mentioned components can be found in existing technologies and will not be elaborated upon here.

[0038] Please see Figure 2 , Figure 2 This is a circuit connection diagram of the smart glasses temple 100 provided in one embodiment of this application. In this embodiment, a power source supplies power to the various electrical components in the smart glasses temple 100. For example, the battery 250 is connected to and supplies power to the camera 220, processor 210, storage module 230, and wireless communication module 240, respectively. In other embodiments of this application, if the smart glasses temple 100 also includes other electrical components, such as a microphone or speaker, these other components are also connected to the battery 250 so that the battery 250 supplies power to them.

[0039] In the embodiments of this application, the processor 210 is configured with a program that can control the operation of various electrical components in the temple 100 of the smart glasses. The processor 210 and its program can be referred to the prior art, and will not be elaborated here.

[0040] In the embodiments of this application, the camera 220 is connected to the processor 210 and the storage module 230 respectively. The camera 220 can perform image acquisition in response to the control of the processor 210 and store the acquired image data in the storage module 230.

[0041] In the embodiments of this application, the wireless communication module 240 is connected to the processor 210 and the storage module 230. The wireless communication module 240 can communicate with other temples. For example, a pair of smart glasses includes two smart glasses temples 100, and the two smart glasses temples 100 are connected to each other via the wireless communication module 240. The smart glasses temples 100 can also be connected to other devices via the wireless communication module 240, such as mobile phones, tablets, etc.

[0042] In one embodiment of this application, the wireless communication module 240 can also be connected to the camera 220, and the image data collected by the camera 220 can be transmitted to other devices through the wireless communication module 240.

[0043] A pair of smart glasses includes two temples. Some smart glasses have identical or different circuits on the two temples, which may need to work together to function. This involves signal transmission between the two temples. Therefore, during functional testing or normal use, a communication connection is required between the two temples for signal transmission. In this application, the two temples of the smart glasses can achieve a wireless communication connection via a wireless communication module 240 to transmit signals wirelessly. This method eliminates the need for circuitry within the frame to establish a communication connection between the two temples, effectively reducing the complexity of testing the collaborative functions between the two temples, eliminating the need to develop corresponding frame circuitry, and lowering development costs.

[0044] In smart glasses, the glasses are typically used to collect data in front of the wearer after being worn. Accordingly, in the embodiments of this application, the camera 220 is also used to collect data in front of the wearer. Therefore, the camera 220 is positioned facing forward. Here, "forward" can also be understood as the direction in which the rear end of the temple 100 of the smart glasses points towards the front end. In this application, the front end, rear end, front, and rear of the temple 100 of the smart glasses can refer to the position or direction when wearing existing glasses, and will not be further described here.

[0045] In one embodiment of this application, the camera 220 may be positioned at the front end and facing forward to capture images in front of the front end of the smart glasses temple 100.

[0046] In one embodiment of this application, the surface of the front end can be transparent, for example, using materials such as glass or transparent acrylic sheet. In some embodiments, the surface of the front end may also have a through hole, and the camera 220 is disposed in the through hole.

[0047] Please see Figure 3 , Figure 3 This is a schematic diagram of a protrusion 130 provided in one embodiment of this application. In another embodiment of this application, a protrusion 130 is provided on the upper surface of the housing, a receiving cavity 120 communicates with the interior of the protrusion 130, and a camera 220 is fixedly disposed on the protrusion 130, with the camera 220 facing forward. Similarly, the protrusion 130 can also be disposed on the side surface of the housing other than the side where the connector is located. Figure 3 (Not shown).

[0048] The interior of the protrusion 130 is also hollow, accommodating the camera 220. The camera 220 is fixedly mounted within the protrusion 130, facing forward to capture images from in front of the smart glasses. The receiving cavity 120 connects to the interior of the protrusion 130, meaning the hollow portion inside the protrusion 130 is part of the receiving cavity 120. The camera 220 can be electrically connected to other electrical components within the receiving cavity 120.

[0049] The camera 220 has a certain size, which requires the housing to have a certain length and width to accommodate it, potentially resulting in a relatively large overall size of the temples. In this embodiment, an additional protrusion 130 is provided to accommodate the camera 220. This allows the main body of the smart glasses temple 100 housing to be appropriately reduced in size for easier wearing, minimizing obstruction of the field of vision and light caused by the excessive size of the front end of the smart glasses temple 100. Simultaneously, it ensures that the camera is not obstructed by the frame, temples, or other components, facilitating the capture of objects in front of the user.

[0050] In some embodiments, if the camera 220 is disposed on the protrusion 130, the connecting portion 110 may also be disposed on the front surface of the temple 100 of the smart glasses.

[0051] In one embodiment of this application, the temple of the smart glasses 100 may further include a speaker, which is disposed in the receiving cavity 120 and connected to the processor 210 and the storage module 230 respectively.

[0052] The smart glasses temple 100 can be configured with audio playback function through the speaker, processor 210 and storage module 230, enabling the testing of audio playback function and expanding the scope of use of the smart glasses temple 100.

[0053] The section from the middle to the rear of the temple is closer to the wearer's ear. Therefore, in this embodiment, the speaker can be located in the receiving cavity 120 of the smart glasses temple 100, near the middle or near the rear of the smart glasses temple 100. Meanwhile, to reduce the obstruction of sound propagation by the housing, a through-hole can be provided in the receiving cavity 120 at the location of the speaker to connect to the surface of the housing, so that sound can be propagated through this through-hole.

[0054] In one embodiment, the smart glasses temple 100 further includes a microphone group disposed within the receiving cavity 120. The microphone group includes at least one microphone, and each microphone is connected to the processor 210 and the storage module 230.

[0055] Some smart glasses require audio capture, such as for recording and voice calls. Simultaneously, audio information may also need to be captured during image capture. Therefore, in the embodiments of this application, a microphone can be installed in the temple, enabling the temple to capture voice, expanding the application range of the smart glasses temple 100 and enriching its functional diversity. Furthermore, the audio capture function can be tested while testing the temple.

[0056] In scenarios such as voice calls and recordings, it is necessary to identify whether the wearer is speaking in order to perform voice noise reduction. Similarly, in functions such as voice assistants, it is necessary to recognize the wearer's voice commands and whether the wearer is speaking. Currently, differential signaling can be used to determine the direction of the sound source and thus determine whether the user is speaking. Therefore, in some embodiments of this application, the microphone group can include a first microphone and a second microphone, and the distance between the first microphone and the second microphone is greater than a preset distance.

[0057] Please see Figure 4 , Figure 4This is a schematic diagram of the microphone position relationship provided in an embodiment of this application. Mic1 and Mic2 represent the first microphone and the second microphone, respectively; d0 is the distance between the first microphone and the second microphone; S1 is the direction from the first microphone to the second microphone (S1 can be denoted as the first direction); S2 is the direction from the second microphone to a preset position P (S2 can be denoted as the second direction); and α is the angle between the first direction and the second direction.

[0058] In this embodiment, d0 is greater than a preset distance. The preset distance can refer to the requirements of differential audio signals when identifying the direction of a sound source through differential audio signals in the prior art, and is not limited here.

[0059] Therefore, the first and second microphones can collect different audio signals with differences in phase, power, or amplitude, i.e., differential audio signals. The processor 210 can then identify whether the wearer is speaking based on the differential audio signals collected by the first and second microphones. For example, the processor 210 is configured to determine whether the wearer of the smart glasses with the temple is speaking based on the amplitude difference, power difference, or phase difference of the audio signals collected by the first and second microphones respectively. The method by which the processor 210 determines the direction of the sound source based on the differential audio signals and thus determines whether the wearer is speaking can be found in existing technologies and will not be elaborated upon here.

[0060] Since the temples of glasses are usually small, in order to make the audio signals collected by the two microphones as different as possible, the first microphone can be placed above the receiving cavity 120 and the second microphone can be placed below the receiving cavity 120. Compared with the two being on the same horizontal line, placing one microphone above and the other below can increase the distance between the two as much as possible, thereby increasing the phase difference, amplitude difference or power difference of the audio signals collected by the two.

[0061] To determine whether a wearer is speaking, it is necessary for the differential audio signals to differ in the direction of the sound source to be identified. For example, to identify whether a wearer is speaking, it is necessary to determine the difference between different audio signals in the direction of the wearer's mouth.

[0062] Since smart glasses are worn on the ears, when the distance between the first and second microphones is the same, compared to when they are on the same horizontal plane, the way the first and second microphones are positioned one above the other maps to a greater distance between the smart glasses and the wearer's mouth (i.e., the sound source), which helps to improve the difference between the audio signals collected by the two microphones.

[0063] In conjunction with this application Figure 4As shown, in one embodiment of this application, a preset position P is further configured, which is a preset position of the wearer's mouth, and the angle α between the first direction and the second direction is within a preset angle range. This allows for a further increase in the mapping distance between the distance between the first microphone and the second microphone onto the plane where the smart glasses and the wearer's mouth (i.e., the sound source) are located, thereby improving the difference between the audio signals collected by the first microphone and the second microphone, and improving the accuracy of wearer speech recognition.

[0064] In this embodiment, the theoretically optimal angle within the preset angle range is 0°, with the first microphone, the second microphone, and the preset position aligned in a straight line. However, considering the differences in head size among different wearers, resulting in varying distances from the ear to the mouth, the preset angle range can be a relatively small range, such as 0 to 20°, 0 to 30°, etc., which can be reasonably set according to the differences in head size among the user group. This will not be elaborated further here.

[0065] Based on the same concept, this application also provides a smart glasses, which includes a frame, a first temple, and a second temple. The first temple and the second temple are respectively the left and right temples of the smart glasses; for example, when the first temple is the left temple, the second temple is the right temple. Conversely, when the second temple is the left temple, the first temple is the right temple.

[0066] The first temple is the smart eyeglass temple 100 provided in any of the foregoing embodiments, and is connected to the frame via a connector. The second temple may be a temple without circuitry, and may be made of materials such as metal or plastic. The frame may also be without circuitry, and includes a metal or plastic outer frame and lenses disposed within the outer frame. The frame and the second temple are also detachably connected via a connector.

[0067] In some embodiments of this application, the first temple and the second temple are both smart glasses temples 100 provided in any of the foregoing embodiments, and the first temple and the second temple are connected wirelessly.

[0068] Based on the same concept, this application also provides a data acquisition system 400. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 This is a schematic diagram of a data acquisition system 400 provided in an embodiment of this application. The data acquisition system 400 includes: smart glasses 300 and a main device 410.

[0069] The smart glasses 300 are the smart glasses provided in any of the foregoing embodiments, or smart glasses including the smart glasses temples 100 provided in any of the foregoing embodiments.

[0070] The main device 410 can be a mobile phone, computer, server, or other device. The main device 410 and the smart glasses are directly or indirectly connected via wireless communication.

[0071] The image and / or audio data collected by the smart glasses 300 can be transmitted to the main device 410 via a wireless communication connection. The main device 410 can send control commands to the smart glasses to control the smart glasses to collect data.

[0072] The smart glasses 300 are a type of wearable mobile device, but due to size limitations, they cannot carry a large battery 250, thus requiring high power consumption.
