[0033] Although smart glasses products have been widely used, most of the existing smart glasses products mainly focus on realizing the interconnection function with mobile phones or providing some augmented reality (AR) experiences, lacking optimization for audio experiences. For example, the audio signals played by the earphones used in existing smart glasses are easily interfered by environmental noise signals. When users use earphones in a noisy environment, they often need to cover their ear canals, resulting in poor experience and potential safety hazards during use. Secondly, voice interaction is one of the important interaction methods of smart glasses, and users can complete various operations on smart glasses through voice. However, most smart glasses products mainly rely on network connections for voice recognition and processing through the cloud. These devices usually do not have the local wake-up ability in an offline environment, resulting in limited usage scenarios in a network-free state.

[0034] Please refer to Figure 1 and Figure 2 In this embodiment, a smart glasses device 100 is disclosed, which includes a glasses frame, a microcontroller 110, a wireless communication module 120, a bone conduction module 130, a wake-up button 140, and a sound pickup module 150. The glasses frame is equipped with glasses lenses. The microcontroller 110 is installed on the glasses frame. The wireless communication module 120 is electrically connected to the microcontroller 110. The bone conduction module 130 is installed on the glasses frame and is electrically connected to the microcontroller 110. The wake-up button 140 is installed on the glasses frame and is electrically connected to the microcontroller 110. The wake-up button 140 is used to wake up the microcontroller 110 from a sleep or standby state. The sound pickup module 150 is electrically connected to the microcontroller 110. The sound pickup module 150 is used for voice signal acquisition and wake-up word recognition to wake up the microcontroller 110 from a sleep or standby state.

[0035] In this embodiment, the microcontroller 110 is used to control the operation and coordination of each module. The wireless communication module 120 includes a Bluetooth module 121 and a WIFI module 122. The Bluetooth module 121 is used to implement wireless communication between the smart glasses device 100 and external devices (such as smartphones, tablets, etc.). Through the Bluetooth module 121, functions such as voice calls, data synchronization, receiving notifications, and controlling music playback can be performed. Among them, the Bluetooth module 121 adopts low-power Bluetooth technology, which can effectively save power and extend the usage time of the smart glasses device 100. The WIFI module 122 is used to connect to the server 200 to achieve voice interaction with the cloud large model, data synchronization, and acquisition of online information. The bone conduction module 130 is used to conduct audio signals through the user's skull and directly transmit the sound signals to the user's inner ear, avoiding covering the ear canal. The advantage of the bone conduction module lies in liberating the ear canal and is especially suitable for use in situations where it is necessary to remain alert to environmental sounds, such as during outdoor sports or driving. The bone conduction module 130 can also reduce ear fatigue and provide a comfortable long-term wearing experience. Generally speaking, the bone conduction module 130 is installed on the temple part of the glasses frame, which can provide a lossless audio experience, especially suitable for noisy environments, allowing users to maintain awareness of the surrounding environment and facilitating improving safety during use.

[0036] The smart glasses device 100 of this embodiment supports two wake-up methods: button wake-up and voice wake-up. The two methods are respectively applicable to different usage scenarios, ensuring that the smart glasses device 100 can quickly respond to user operations in a low-power state.

[0037] Button wake-up: The smart glasses device 100 operates in a low-power mode to save power. When the user presses the wake-up button 140, the smart glasses device 100 (microcontroller 110) will wake up from the sleep or standby state and resume the normal working state. The button wake-up function is applicable when the user needs clear operation control, such as in outdoor, noisy environments, or when the smart glasses device 100 has not been used for a long time. The position of the wake-up button 140 is usually set on the temple part of the glasses frame or other convenient positions for operation. The user can wake up the smart glasses device 100 through a simple press. The button wake-up function is direct, fast, and not interfered by surrounding environmental sounds.

[0038] Voice wake-up: It is achieved through the sound pickup module 150 and voice recognition technology. When the smart glasses device 100 is in the low-power standby state, the sound pickup module 150 is used to collect the voice signals issued by the user and recognize the wake-up words in the voice signals. When the wake-up words are recognized, the smart glasses device 100 is activated from the sleep state. Voice wake-up is applicable to scenarios where users need to operate without manual intervention, especially when it is inconvenient to operate the device with both hands. For example, during driving, sports, or daily conversations, users can wake up the smart glasses device 100 and interact with it through voice control. Voice wake-up provides a more natural and convenient interaction method. Users can directly start the device through voice without pressing buttons, which is especially suitable for hands-free operations in complex tasks or scenarios.

[0039] The microcontroller 110 is also electrically connected to a camera module 160 and an optical engine waveguide module 170. The camera module 160 is used to collect image signals and transmit them to the microcontroller 110. The optical engine waveguide module 170 is used to project the signal to be displayed onto the glasses lenses to achieve the function of augmented reality (AR). The optical engine waveguide module 170 ensures that the image can be clearly and stably displayed within the user's field of view through optical projection technology. The waveguide technology provides a more lightweight structural design and reduces the impact on the weight of the glasses. The camera module 160 is used to implement functions such as image acquisition, video recording, and real-time image transmission. In addition, the microcontroller 110 is also electrically connected to an internal memory 180 and an external memory 190. The internal memory 180 is used to implement the temporary storage function during the operation of the smart glasses device 100. The external memory 190 is used to store a large amount of data, such as programs, font libraries, pictures, and device logs, etc. It should be noted that the smart glasses device 100 also includes a power supply module, which is used to provide power for the smart glasses device 100.

[0040] Installing the bone conduction module 130 on the glasses frame can transmit the audio signal to the user through the bone conduction module 130, avoiding interference from environmental noise to the audio signal and facilitating the optimization of the audio experience. Installing the wake-up button 140 and setting the sound pickup module 150 on the glasses frame to collect voice signals and recognize wake-up words enables the selection of button wake-up or voice wake-up according to actual application requirements, which is conducive to adapting to different application scenarios.

[0041] Among them, the bone conduction module 130 includes a bone conduction speaker and a power amplifier circuit module 131. The bone conduction speaker is electrically connected to the power amplifier circuit module 131 and is electrically connected to the microcontroller 110 through the power amplifier circuit module 131. The audio signal output by the microcontroller 110 is amplified by the power amplifier circuit module 131 and then transmitted to the bone conduction speaker. The bone conduction speaker is used to convert the audio signal into a vibration wave signal and conduct it to the user's inner ear through the user's skull. The audio signal is directly conducted in a vibrating manner, and the sound can be heard without passing through the user's ear canal, avoiding interference from environmental noise. Exemplarily, please refer to Figure 3 , Figure 3 shows the circuit schematic diagram of the power amplifier circuit module 131, where the interface J1 is used to connect the bone conduction speaker, the chip U3 is a power amplifier chip, and the terminals MUTE, DACFL, and DACFR are respectively connected to the corresponding pins of the microcontroller, and the terminal VMCU is connected to the power supply module.

[0042] The number of bone conduction modules 130 is two, and the two bone conduction modules 130 are respectively electrically connected to the microcontroller 110. The two bone conduction modules 130 are respectively installed on the left and right temple parts of the glasses frame, and can realize the transmission of stereo audio signals. Among them, the microcontroller 110 is built-in with multiple DAC modules, and the multiple DAC modules are configured as single-ended output circuits or differential pair output circuits. Please refer to Figure 3 , Figure 3 In the wiring terminals DACFL and DACFR are respectively connected to the DAC module of the microcontroller, and can be configured as a single-ended output circuit or a differential pair output circuit. The differential pair output circuit is beneficial to improving the anti-interference ability of the circuit and improving the audio experience.

[0043] According to the requirements of actual applications, the pickup module 150 is configured as a single microphone circuit module or a dual microphone circuit module. The dual microphone circuit module can collect the user's voice signal more accurately. Among them, the single microphone circuit or the dual microphone circuit needs to have high sensitivity and noise suppression ability to ensure accurate identification of the user's voice signal, especially in a noisy environment, it can still pick up the sound clearly. Exemplarily, please refer to Figure 4 , Figure 4 shows the circuit schematic diagram of the single microphone circuit module. The terminals MIC1P and MIC1N are the wiring pins of the pickup microphone MIC. The terminals MIC1P and MIC1N are respectively connected to the corresponding pins of the microcontroller, and the terminal DACVDD is connected to the corresponding pin of the microcontroller to supply power to the pickup microphone MIC.

[0044] Please refer to Figure 1 and Figure 2, this embodiment further provides an intelligent glasses system, including the above-mentioned intelligent glasses device 100 and server 200, and the intelligent glasses device 100 is communicatively connected to the server 200. Among them, the structure of the intelligent glasses device 100 can be referred to the above text and will not be elaborated here. A bone conduction module 130 is installed on the glasses frame, and the audio signal can be transmitted to the user through the bone conduction module 130, avoiding the interference of environmental noise on the audio signal and being beneficial to optimizing the audio experience; a wake-up button 140 is installed on the glasses frame and a voice pickup module 150 is set to collect voice signals and recognize wake-up words, and button wake-up or voice wake-up can be selected according to actual application requirements, which is beneficial to adapting to different application scenarios.

[0045] The intelligent glasses device 100 can directly communicate with the server 200. For example, the intelligent glasses device 100 is connected to the server 200 through the WIFI module 122, so as to perform language interaction with the cloud large model carried on the server 200. In addition, the intelligent glasses device 100 can also communicate with the server 200 by means of a third-party device. For example, the intelligent glasses system further includes an intelligent terminal 300 (such as a smart phone, a tablet computer, etc.), the intelligent glasses device 100 is wirelessly connected to the intelligent terminal 300, and is communicatively connected to the server 200 through the intelligent terminal 300. The intelligent glasses terminal is wirelessly connected to the intelligent terminal 300 through the Bluetooth module 121 and then communicates with the server 200 through the intelligent terminal 300. This method also supports two communication methods: for example, in the first method, there is no need to install an APP or a small program (such as a WeChat small program) on the mobile phone side (intelligent device), and the intelligent glasses device 100 directly performs TCP / IP communication with the server 200 through the Bluetooth module 121; in the second method, through the APP or small program installed on the mobile phone side (intelligent device), the intelligent device serves as a transfer station for the large model protocol to coordinate the data interaction between the intelligent glasses device 100 and the server 200, and the intelligent glasses device 100 communicates with the intelligent terminal 300 through the Bluetooth protocol.

[0046] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings.
