[0058] The aforementioned voice recognition module 200 serves as the device's auditory center. Equipped with a high-precision microphone array including a noise-reducing pickup unit, it can accurately capture voice signals within a 5-meter range. Its core functions include: responding to the "AI" physical button trigger: when the user presses the "AI" button on the front, the module immediately enters an active state, initiating voice acquisition. Button triggering has the highest priority to avoid false wake-ups. Supporting potential voice wake-up expansion: An interface is reserved for wake-up word recognition algorithms, such as integrating wake-up words like "Little X Student" later. Low-power standby wake-up is achieved through a local offline recognition engine, with a wake-up response time ≤0.5 seconds. Raw voice signal preprocessing: The acquired audio is filtered and echo-cancelled to reduce interference from environmental noise such as appliance noise and outdoor sounds.

[0059] The aforementioned audio processing module 300 mainly consists of a digital signal processor (DSP) and an audio codec, responsible for converting the input analog audio signal into a digital signal for further processing and analysis. Specifically, the audio processing module 300 includes the following key steps:

[0060] In the speech signal conversion stage, the audio processing module 300 receives the analog audio signal from the speech recognition module 200 and converts it into a digital signal. This process typically uses a 16kHz sampling rate and 16-bit quantization precision to ensure signal integrity and accuracy. Through this conversion, the analog signal is digitized, facilitating subsequent processing and analysis.

[0061] In the feature extraction and optimization stage, the audio processing module 300 utilizes advanced algorithms such as Mel-frequency cepstral coefficients (MFCC) to extract key features from the speech signal. These features include instruction keywords (such as "open" and "search"), and by enhancing the signal features of these keywords, the accuracy of speech recognition can be significantly improved. This stage is a crucial step in ensuring that the system can accurately understand user commands.

[0062] In the audio processing stage, the audio processing module 300 is responsible for converting the text response returned from the cloud into a speech signal. This process is mainly achieved through a TTS (Text-to-Speech) engine, which converts text information into speech information. To ensure clarity and naturalness in playback, the audio processing module 300 also performs sound effect optimization, including automatic volume adjustment and speech rate regulation. Through these optimization measures, users can hear clear and natural voice feedback, improving the overall user experience.

[0063] In summary, the audio processing module 300 ensures accurate recognition of speech signals and high-quality speech feedback through key steps such as signal translation, feature extraction and optimization, and feedback audio processing, providing a solid foundation for the efficient operation of the entire system.

[0064] The aforementioned wireless communication module 400 acts as a bridge connecting to the cloud, enabling terminal devices to interact with the internet in real time.

[0065] In terms of data transmission, the wireless communication module 400 adopts a dual-band design of 2.4GHz and 5GHz. This design not only provides a wider coverage range but also effectively avoids frequency band congestion, thus ensuring real-time transmission of voice data and feedback information. The voice data transmission rate is approximately 100kbps, which is sufficient for most application scenarios. To further enhance the user experience, the wireless communication module 400 has also optimized latency control, ensuring that the latency is always kept within 300 milliseconds, thereby achieving a smooth interactive experience.

[0066] In terms of network adaptation, the wireless communication module 400 features intelligent signal detection. When a weak WiFi signal is detected, the module automatically switches to a stronger frequency band to maintain a stable network connection. Furthermore, the module supports a reconnection mechanism, enabling rapid reconnection within 3 seconds in the event of an unexpected network interruption, ensuring continuity of interaction and preventing a decline in user experience due to network issues.

[0067] To ensure data transmission security, the wireless communication module 400 employs the latest WPA3 encryption protocol. This encryption protocol effectively prevents voice commands from being intercepted or tampered with during transmission, thereby protecting user privacy and data security. With this robust encryption mechanism, users can use the device with confidence, without worrying about the risk of data leakage.

[0068] In summary, the wireless communication module 400, by integrating an advanced WiFi wireless module, achieves high-speed, stable, and secure data transmission, providing a solid foundation for seamless connectivity between smart devices and the cloud. Whether it's real-time voice data transmission, network adaptation, or secure encryption, the wireless communication module 400 demonstrates superior performance, delivering an exceptional user experience.

[0069] The control keys are at least one of the following: buttons, knobs, joysticks, touch keys, and gear adjustment keys.

[0070] The aforementioned control keys refer to specific physical or touch-sensitive components used to operate equipment or achieve interactive functions. These include buttons (press-type switches), knobs (rotary adjustment devices), joysticks (control levers that can be pushed in multiple directions), touch keys (sensing areas triggered by touch), and gear adjustment keys (adjustment devices with gear structures). These control keys are one of the interfaces for users to manually operate the terminal device.

[0071] The design of the aforementioned control keys not only prioritizes practicality but also considers aesthetics and ergonomic principles, ensuring users can operate them easily and accurately, minimizing the possibility of accidental touches and misoperations. For example, the button's pressing force and travel have been carefully calibrated to ensure that users do not feel overly strained or that it is too soft, leading to accidental touches; the knob's damping feel and rotation angle range have also been optimized, allowing users to finely adjust parameters to meet different operational needs.

[0072] Reference Figures 1-6 As shown, in some examples, the control keys include a power button 110, an "AI" interaction button 120, and a communication button 130. The power button 110 is used to turn the terminal device on and off, the "AI" button is used to trigger the AI ​​voice interaction function, and the communication button 130 is used for network connection configuration.

[0073] The design of these function-specific control keys further enhances the convenience and intuitiveness of user operation. The power button 110 is usually logically positioned, making it easy for users to quickly find and turn the device on and off. Its button design often features clear markings, ensuring easy identification even in low-light conditions. The "AI" interaction button 120 is marked with a prominent icon or text; once pressed, it quickly activates the AI ​​voice assistant, enabling voice command input and interaction, greatly simplifying the operation process. The communication button 130 is dedicated to network connection configuration and management. With a simple press, users can access the network settings interface to search for, connect to, and enter passwords for wireless networks, eliminating the need for cumbersome menu navigation and improving the efficiency and convenience of network configuration.

[0074] In some examples, the main housing 100 is provided with a radially arranged array of sound holes 140, and the position of the in-cavity audio output module 500 is adapted to the array of sound holes 140.

[0075] This design is not only aesthetically pleasing but also effectively improves sound propagation efficiency and sound quality. The radial arrangement of the sound outlet array 140 allows sound to diffuse evenly in all directions, avoiding excessive concentration or attenuation of sound in any one direction, thus providing users with a clearer and more immersive listening experience. Simultaneously, the precise positioning of the audio output module 500 within the housing ensures smooth sound transmission through the sound outlet array 140, reducing sound loss and distortion during transmission and further enhancing sound quality. This design not only reflects a high level of attention to the user's auditory experience but also showcases the product's meticulous attention to detail.

[0076] The aforementioned structure can form a high-precision microphone array (which may include the noise-reducing pickup unit described below), capable of accurately capturing voice signals within a 5-meter range. Its core functions include responding to "AI" physical button triggers, supporting potential voice wake-up extensions, and preprocessing of raw voice signals. In this case, the voice recognition module 200 can serve as the auditory center of the entire device.

[0077] The audio output module 500 may include a miniature speaker. In this application, the audio output module 500 can work with radial sound holes to achieve voice feedback. It consists of a miniature speaker (3W power, frequency response range 100Hz-20kHz) and a power amplifier circuit, including directional audio output and dynamic volume adjustment.

[0078] Specifically, the audio output module 500 provides clear voice feedback through radially arranged sound outlets on the front. The audio output module 500 may comprise a miniature speaker and an amplifier circuit. The miniature speaker has a power output of 3W and a frequency response covering a wide range from 100Hz to 20kHz, ensuring high-quality and rich audio output. The amplifier circuit amplifies the speaker's output signal to achieve sufficient volume and clarity.

[0079] For directional audio output, the sound outlets employ a radial layout design, covering a 120° sound field. This layout ensures that users can clearly hear the feedback voice within an area of ​​1 to 3 meters in front of the device. Whether the user is standing or sitting, this design ensures that the audio signal is directly transmitted to the user's ears, thus providing a better listening experience.

[0080] Dynamic volume adjustment is another important feature of the audio output module 500. This function uses the voice recognition module 200 to detect the ambient noise level in real time and then automatically adjusts the output volume based on the detection results. The volume adjustment range is between 5 and 85 decibels, ensuring that users will not have difficulty hearing the feedback voice due to background noise in noisy environments, while also avoiding discomfort from excessive volume in quiet environments. This adaptive volume adjustment mechanism greatly enhances the user experience, enabling the audio output module 500 to provide optimal listening performance in various environments.

[0081] In some examples, the terminal device also includes a noise reduction pickup unit disposed within a receiving cavity. The noise reduction pickup unit and the sound output array 140 work together with the audio processing module 300 to filter background noise and enhance the clarity of the speech signal through a preset algorithm.

[0082] This design ensures that voice commands are accurately recognized and executed even in noisy environments when using the AI ​​voice interaction function. The collaborative work of the noise-reducing pickup unit and the audio processing module 300, through advanced algorithms, intelligently distinguishes user voice from background noise, effectively suppressing external interference and improving the accuracy and efficiency of voice recognition. This not only enhances user comfort but also further improves the overall intelligence level and user experience of the terminal device.

[0083] The sound outlet array 140 can also be other types of arrays, such as square arrays, circular arrays, etc. The cross-sectional shape of the sound outlet itself can also be set as needed, such as circular, rectangular (square, rectangle), rhombus, plum blossom shape, shell shape, ellipse, semicircle, combined shape, irregular shape, etc.

[0084] These diverse array configurations and cross-sectional shapes not only satisfy the personalized aesthetic needs of different users but also take into account the efficiency and quality of sound transmission. For example, a circular array may be more suitable for scenarios requiring 360-degree omnidirectional sound, while a square array may be more compact and efficient in certain specific layouts. The choice of cross-sectional shape may be based on acoustic principles, aiming to reduce airflow resistance and improve sound purity and response speed. Through these meticulous design details, this terminal device not only provides high-quality audio output but also demonstrates its dual pursuit of design aesthetics and functional practicality.

[0085] The terminal device is a portable device, and the longest linear dimension on the terminal device is no more than 100mm.

[0086] This allows the device to easily fit into a pocket or small bag, making it convenient for users to carry around. Whether at home, in the office, or traveling outdoors, users can enjoy a high-quality AI voice interaction and control experience anytime. Furthermore, its compact size means the device saves space and reduces unnecessary energy consumption, aligning with modern technological products' pursuit of environmental protection and energy conservation.

[0087] In some examples, the main body shell 100 is at least one of a prism, cylinder, sector prism or irregular three-dimensional structure, wherein the corners of the main body shell 100 are at least partially set as rounded corners.

[0088] This design not only enhances the device's feel and aesthetics but also effectively prevents accidental scratches during use, increasing the product's durability. The rounded corners also take ergonomic principles into account, reducing hand fatigue and improving overall comfort during extended use. Furthermore, the availability of different body shell shapes provides users with diverse options, allowing them to flexibly choose the most suitable style based on personal preference and usage scenario.

[0089] Reference Figures 1-6 As shown, in some examples, the main body shell 100 is a cuboid with a length of 65mm ± 15mm, a width of 62mm ± 15mm, and a height of 30mm ± 15mm.

[0090] Alternatively, the main shell 100 is a cube with a side length of 50mm ± 15mm.

[0091] In some specific examples, the main housing 100 is designed as a cuboid structure. In this case, the length of the main housing 100 is specified as 65 mm, with an adjustable range of ±15 mm. That is, the actual length of the manufactured main housing 100 can be between 50 mm and 80 mm, depending on the required dimensions. Furthermore, the width of the main housing 100 is set at 62 mm, also allowing for an adjustment range of ±15 mm, meaning the actual length can vary between 47 mm and 77 mm. The height of the main housing 100 is set at 30 mm, again with an adjustment range of ±15 mm, so the actual length can be between 15 mm and 45 mm.

[0092] The length, width, and height dimensions mentioned above are relative, and the specific values ​​may vary depending on the placement of the terminal device and the usage environment. In practical applications, users should purchase terminal devices with the appropriate length, width, and height dimensions based on the specific placement location and space conditions to achieve better usage results.

[0093] The main housing 100 can also be designed as a cube. In this case, the side length of the main housing 100 is specified as 50 mm, with an adjustment range of ±15 mm allowed. The actual side length of the manufactured main housing 100 can be adjusted between 35 mm and 65 mm. These specific design parameters ensure that the main housing 100 maintains a certain dimensional accuracy during manufacturing, while allowing for certain manufacturing tolerances to meet the needs of actual production.

[0094] The specific dimensions mentioned above also need to take into account the size of each module to ensure the complete functionality of the terminal device.

[0095] This size design ensures the device can be easily slipped into a pocket or bag for convenient portability, while also providing sufficient internal space to accommodate key components such as the battery, motherboard, microphone, and speaker, thus guaranteeing the proper functioning of AI voice interaction and control. Furthermore, the diverse size options offer users more choices, allowing them to select the most suitable size based on their carrying habits and usage needs. In addition, the main body's 100mm size takes into account the different hand shapes of various users, making the device more ergonomic and comfortable to hold, enhancing both comfort and stability.

[0096] The terminal device can be equipped with at least one of the following interfaces as needed: Type-C interface 150, Apple interface, and USB interface. Other types of interfaces can also be added. Taking the Type-C interface 150 as an example, the Type-C interface 150 serves both charging and data transmission. A status indicator light 160 can be set on one side of the Type-C interface 150 to clearly display the device status, thus meeting the functional and practical needs of smart devices.

[0097] Display modules, such as LED displays and LCD displays, can also be installed on the terminal device as needed to display the status of other modules and simulate interactions.

[0098] Reference Figures 1-6 As shown, in some examples, the voice recognition module 200 includes an electrically connected analog-to-digital converter and at least one microphone, and the main housing 100 is provided with at least one microphone hole 180.

[0099] Microphone hole 180 is used to receive external voice signals and transmit them to the microphone. After the microphone receives the external voice signals, the analog-to-digital converter converts the external voice signals into recognizable digital signals.

[0100] These digital signals are then transmitted to the central processing unit (CPU), which has an advanced built-in speech recognition algorithm that can quickly and accurately analyze these signals to recognize the user's voice commands. This process not only improves the speed and accuracy of speech recognition but also provides users with a smoother and more natural interactive experience. Meanwhile, the microphone hole 180 is designed with dust and water resistance in mind, ensuring stable speech recognition functionality in various complex environments. Furthermore, the speech recognition module 200 supports the recognition of multiple languages ​​and dialects, further expanding the user base and meeting the personalized needs of different users.

[0101] The audio processing module 300 also includes an audio encoding unit for encoding the processed digital signal into a format suitable for wireless network transmission.

[0102] This encoding process ensures the efficiency and stability of audio data transmission, reducing the possibility of data loss and errors. The audio encoding unit employs advanced encoding algorithms that compress data size as much as possible while maintaining sound quality, thereby improving transmission efficiency and saving bandwidth resources. Furthermore, the audio processing module 300 supports multiple wireless network protocols, such as Wi-Fi and Bluetooth, enabling terminal devices to flexibly adapt to different network environments and achieve seamless connectivity and stable transmission. This design not only enhances the user experience but also provides strong support for the widespread application of terminal devices in various scenarios such as smart homes, industrial applications, and automotive systems.

[0103] The aforementioned audio encoding unit can also be replaced with a Digital Signal Processor (DSP). Appropriate components can be selected as needed. A DSP receives digital signals from an analog-to-digital converter and performs processing operations such as noise reduction and enhancement. The DSP analyzes the frequency, amplitude, and other characteristics of the digital signal through algorithms, removing background noise and enhancing the speech signal, thereby improving the accuracy and efficiency of speech recognition.

[0104] Audio encoding units and digital signal processors (DSPs) share some similarities in function and application, but there are also significant differences. An audio encoding unit is primarily responsible for converting analog audio signals into digital signals and performing compression and encoding for storage and transmission. A DSP, on the other hand, is a microprocessor specifically designed for processing digital signals; it can execute various complex algorithms to process and optimize digital signals.

[0105] The core function of an audio encoding unit is to convert analog audio signals into digital signals and then compress and encode them. This process typically involves three steps: sampling, quantization, and encoding. Sampling converts a continuous analog signal into a discrete signal; quantization converts continuous signal values ​​into finite values; and encoding compresses and formats the quantized signal for storage and transmission. Audio encoding units usually use specific encoding algorithms, such as MP3 and AAC, to achieve high compression ratios and good sound quality.

[0106] A digital signal processor (DSP) is a microprocessor specifically designed for processing digital signals. DSPs can execute various complex algorithms, performing operations such as filtering, modulation, decoding, and echo cancellation on digital signals. The advantages of DSPs lie in their high-speed processing capabilities and flexibility, enabling them to handle complex signal processing tasks in real time. DSPs are widely used in audio, video, communications, and medical fields, such as in mobile phones, audio equipment, and medical imaging devices.

[0107] While there is some functional overlap between audio encoding units and digital signal processors (DSPs), their primary responsibilities and application scenarios differ. Audio encoding units are mainly responsible for the conversion and encoding of audio signals, while DSPs focus on performing various complex processing and optimizations on digital signals.

[0108] In some examples, the wireless communication module 400 includes at least one wireless communication unit selected from Wi-Fi, Bluetooth, Zigbee, and NFC.

[0109] The wireless communication module 400 can use one or more of Wi-Fi, Bluetooth, Zigbee, or NFC for data transmission. These technologies each have different characteristics and application scenarios. For example, Wi-Fi is suitable for high-speed data transmission, Bluetooth is often used for short-range device connections, Zigbee is suitable for low-power IoT devices, and NFC is mainly used for short-range payments or information exchange.

[0110] A wireless communication module 400 refers to a hardware component that enables data transmission between devices via wireless signals. It can be integrated into various devices, such as mobile phones and smart home devices, to achieve interconnectivity. Wi-Fi is a common wireless network technology primarily used for high-speed data transmission within a local area network (LAN), widely used for internet access in homes, offices, and public places. Bluetooth is a short-range wireless communication technology typically used to connect peripherals such as headphones, keyboards, and mice, and can also be used for audio transmission between mobile phones and in-vehicle systems. Zigbee is a low-power, low-data-rate wireless communication technology commonly used in smart homes and industrial control scenarios, suitable for devices requiring long-term operation and small data volumes. NFC, short for Near Field Communication, is a short-range, high-frequency wireless communication technology primarily used for mobile payments, access card emulation, and rapid pairing between devices.

[0111] In some examples, the audio output module 500 includes a speaker or headphone jack for converting received audio signals into sound output.

[0112] In the above structure, the audio output module 500 may include a speaker or a headphone jack. The main function of these components is to convert the received audio signal into sound output so that the user can hear the corresponding audio content. The speaker converts electrical signals into sound waves through its internal driver unit, thereby producing audible sound. The headphone jack allows the user to receive audio signals by plugging in headphones or earbuds, and the headphones or earbuds convert the electrical signals into sound, allowing the user to enjoy audio content in a more private environment without disturbing those around them. Whether through a speaker or a headphone jack, the audio output module 500 ensures effective conversion of the audio signal, enabling the user to clearly hear the desired sound information.

[0113] Furthermore, the audio output module 500 supports multiple audio formats, ensuring high-quality audio playback. Users can control the volume and switch playback content via AI voice commands, achieving a more intelligent audio experience.

[0114] In some examples, the terminal device also includes an expansion module 190, which includes at least one of a SIM card slot, a memory card slot (as shown in the figures), a data transmission interface, and a wireless charging module.

[0115] These expansion modules 190 are designed to enhance the functionality and flexibility of the terminal device. For example, the SIM card slot allows users to insert a SIM card, enabling the terminal device to have mobile communication capabilities and achieve network connectivity and data transmission without relying on other devices. The memory card slot provides users with additional storage space, facilitating the storage of more applications, audio files, video data, etc., to meet diverse user needs. Data transmission interfaces, such as USB or Type-C interfaces 150, enable the terminal device to exchange data with other devices, realizing functions such as file transfer and device connection. The wireless charging module provides users with a more convenient charging method, enabling charging without plugging and unplugging charging cables, improving the user experience. Through these expansion modules 190, the functionality of the terminal device is greatly expanded, providing users with more comprehensive and convenient services.

[0116] The terminal device is also equipped with a reset hole 170, the position of which can be set as needed. Specifically, the reset hole 170 can be provided on the top or side of the terminal device, and if required, the reset hole 170 can be used for device reset and other operations; the bottom of the terminal device can be provided with a fixing hole to accommodate mounting components and achieve various installation and placement options. Alternatively, the fixing hole on the bottom of the terminal device can be omitted, and a slotted mounting component can be used to snap the terminal device in place.

[0117] In this application, each module can achieve high-speed data interaction through an internal bus (such as I2S, UART), ensuring real-time performance, stability, and scalability.

[0118] The terminal device also includes a power management module 600, which works in conjunction with the power supply to provide power to other modules. The power management module 600 monitors and manages the power status of the terminal device, ensuring that the device operates normally when the battery is sufficient and reminding the user to charge when the battery is low. Simultaneously, the power management module 600 also features intelligent energy-saving functionality, automatically adjusting power consumption based on device usage to extend battery life. Furthermore, when a wireless charging module is included, the power management module 600 works in conjunction with the wireless charging module to ensure a safe and efficient charging process, providing users with a worry-free experience.

[0119] The aforementioned expansion module 190 can be an internal structure. Alternatively, the expansion module 190 can be at least partially disposed on the outer periphery of the main housing 100.

[0120] This design allows the expansion module 190 to be flexibly integrated into the overall structure of the terminal device, maintaining its compactness while providing sufficient expansion space. When the expansion module 190 is a built-in structure, it is cleverly hidden within the main housing 100, without increasing the device's size, and also effectively protects these modules from external environmental interference and damage. When the expansion module 190 is at least partially located on the outer periphery of the main housing 100, users can more easily access and use these modules, such as quickly inserting or removing SIM cards or memory cards, and connecting data cables. This design not only improves user convenience but also enables the terminal device to maintain its compact and lightweight design while possessing powerful functionality and expandability.

[0121] The terminal device for AI voice interaction and control described in this application has the following beneficial effects:

[0122] 1. Compact and portable, suitable for complex scenarios: The terminal device can be 65mm×62mm×30mm in size, with a small overall size (the longest linear dimension ≤100mm), which is a "palm-sized" mini design, significantly better than the physical size of traditional terminal devices (such as industrial-grade control modules, smart speakers, etc.).

[0123] This feature allows it to easily adapt to confined space scenarios such as renovation of old buildings, vertical shafts of high-rise buildings, and wall-embedded installations, solving the problem of difficult handling and installation caused by the excessive size of traditional devices, and improving construction efficiency and scenario adaptability.

[0124] 2. Convenient Operation and Optimized Interactive Experience: 1) Reasonable Layout of Function Buttons: The main body shell 100 has power button 110, "AI" interaction button 120, communication button 130 and other control buttons on its outer periphery. The button trigger priorities are clear (e.g., the "AI" button has the highest priority for triggering voice acquisition to avoid accidental wake-up), allowing users to quickly get started and reducing the learning cost. 2) Optimized Audio Output Design: The main body shell 100 has a radial sound hole array 140 on the front, which, together with the directional audio output of the audio output module 500 (covering a 120° sound field range) and dynamic volume adjustment (automatically adapting to ambient noise from 5-85 decibels), ensures that users can clearly receive feedback voice within 1-3 meters, improving the intuitiveness of the interaction.

[0125] 3. Highly efficient integrated functions and stable, reliable performance: 1) Collaborative operation of core modules: The voice recognition module 200 uses a high-precision microphone array (including noise reduction pickup unit) to accurately capture and preprocess voice signals within 5 meters (filtering, echo cancellation); the audio processing module 300 uses DSP and codec to convert voice signals and optimize features (such as strengthening command keywords) to improve recognition accuracy; the wireless communication module 400 supports dual-band Wi-Fi (2.4GHz / 5GHz) and high-speed data transmission (latency ≤300ms), enabling real-time interaction with the cloud AI platform; each module interacts at high speed through internal buses (I2S, UART), with a full-process response time ≤1.5 seconds, close to the rhythm of natural conversation. 2) Low power consumption and stability assurance: The power management module 600 supports battery management, charging control, and energy-saving mode to ensure continuous and stable operation of the device; the control processing module, as the core unit, coordinates the work of each module and has a fault self-checking function (such as status indicator light 160 alarm when the microphone fails), ensuring the availability of core functions.

[0126] 4. Strong Security and Expandability: 1) Data Security and Privacy Protection: The security module integrates data encryption (such as WPA3 protocol), access control, and security authentication to prevent voice commands from being intercepted or tampered with during transmission and storage, ensuring user privacy. 2) Flexible Function Expansion: The expansion interface module (Type-C interface 150, reserved Bluetooth module interface, etc.) supports connecting to external storage devices, input devices, or expanding Bluetooth peripheral control (such as smart speakers, lighting systems); a reserved voice wake-up algorithm interface allows for the subsequent integration of wake-up word functionality, enhancing the device's functional iteration capabilities.

[0127] 5. Wide adaptability to various scenarios and intelligent upgrades: By integrating AI voice interaction and edge computing functions, the terminal device supports real-time communication with cloud servers and linkage with other smart devices, making it widely applicable in smart homes (voice control of home appliances), industrial automation (voice start / stop of equipment), and vehicle systems (navigation, environmental control), among other scenarios. Simultaneously, the combination of physical dimensions and digital twin models solves the problem of information disconnect in traditional terminal devices, providing data support for the operation and maintenance phase, and enabling intelligent management and efficient operation and maintenance.

[0128] In summary, this device, with its compact design, modular collaboration, safety and reliability, and flexible expansion, optimizes the user experience and adaptability to various scenarios, while also achieving efficient integration of AI voice interaction and control. It possesses strong practical value and market application potential.

[0129] The synergy between control keys and AI voice interaction is mainly reflected in three aspects: trigger logic, functional complementarity, and scenario adaptation. As a trigger point, control keys, such as the AI ​​interaction button, can accurately activate the voice recognition module 200, avoiding accidental wake-up. Meanwhile, the power button 110 and communication button 130 provide basic support, ensuring device response and network transmission. In addition, knobs and gear adjustment keys can be used for mode switching and interaction interruption, preventing invalid commands from consuming resources. In terms of functional complementarity, control keys can compensate for the limitations of voice commands, such as directly adjusting volume or selecting feedback results in noisy environments. They also provide convenient operation of high-frequency functions, such as one-click connection to WiFi or device reset.

[0130] In terms of scenario adaptation, the control keys serve as a backup operation method, ensuring reliability in extreme environments such as strong noise or weak signals, directly triggering preset commands. For different user habits, the control keys offer a dual interaction path of voice and physical input, enhancing operational flexibility. Furthermore, the control keys can directly control the AI ​​voice module, such as muting the microphone, switching noise reduction algorithm modes, or triggering data encryption functions to ensure privacy and security. This collaborative design retains the convenience of AI voice while improving the reliability, accuracy, and scenario adaptability of interaction through the control keys, optimizing user operation convenience and interactive experience.

[0131] In some examples: the terminal device of this application integrates multiple functions, including a power button 110 for powering on / off, an AI button to trigger voice interaction, a WiFi button for configuring network connection, radially arranged sound holes to ensure audio output quality, a Type-C interface 150 for charging and data transfer, a status indicator 160 to display device status, a reset hole 170 for device reset (if required), and mounting holes for various placement options. Internal components include a high-precision microphone array voice recognition module 200 supporting voice wake-up and preprocessing; an audio processing module 300 composed of a DSP and codec, responsible for signal conversion and optimization; a wireless communication module 400 integrating WiFi, compatible with multiple protocols to achieve high-speed and secure transmission (compatible with 802.11a / b / g / n / ac / ax protocols), enabling high-speed data transmission, network adaptation, and secure encryption; and an audio output module 500 composed of a miniature speaker and power amplifier circuit, enabling directional output and volume adjustment. The workflow, taking button triggering as an example, includes triggering, acquisition, local preprocessing, cloud interaction, feedback, and standby stages. Modules interact at high speed via an internal bus, ensuring real-time stability and scalability. In addition, a reserved Bluetooth module interface supports BLE 5.0, which can be expanded to include Bluetooth connectivity for peripherals in the future.

[0132] The complete workflow of the terminal device in this application (taking button triggering as an example) includes the triggering stage, the acquisition stage, the local preprocessing stage, the cloud interaction stage, the feedback stage, and the standby stage.

[0133] Specifically, when a user triggers an operation via a button, the device enters the triggering phase. In this phase, the device detects the button signal and begins to respond. Next, the device enters the data acquisition phase, where it collects relevant data, such as sensor data or other input signals. After acquisition, the device enters the local preprocessing phase, where it performs preliminary processing and analysis on the acquired data to facilitate subsequent processing and transmission.

[0134] After processing is complete, the device enters the cloud interaction phase. In this phase, the device uploads the pre-processed data to the cloud server and receives instructions or data from the cloud server. After cloud interaction is complete, the device enters the feedback phase, where it performs corresponding operations based on the instructions or data from the cloud server, such as displaying results or issuing alarms. Finally, the device enters the standby phase, where it operates in a low-power state, awaiting the next trigger signal.

[0135] The entire workflow covers the entire process from button triggering to the device completing the task and entering standby mode, ensuring the efficient operation and timely response of the terminal device.

[0136] The terminal device used in this application includes, but is not limited to, the following methods:

[0137] I. Power-on and Network Configuration: Power-on Operation: Press the power button 110 on the outer side of the main casing 100. After the device starts up, the side status indicator light 160 will light up (a solid white light indicates that the device is ready to power on). Network Connection: Briefly press the communication button 130 (e.g., the WiFi icon button) to trigger the network configuration mode (the status indicator light 160 will flash). Connect to an external device (e.g., a mobile phone / computer) via the Type-C interface 150, or use the accompanying APP to complete the WiFi network parameter configuration. After a successful connection, the status indicator light 160 will turn solid (a blue light indicates that the network is normal).

[0138] II. AI Voice Interaction Operation: Triggering the Voice Function: Briefly press the "AI" interaction button 120 (highest priority). The device enters the voice acquisition state (the indicator light flashes green). At this time, you can speak voice commands (such as "turn on the living room light" or "check today's weather"). If the voice wake-up function has been extended (the wake-up word needs to be configured in advance), you can activate the interaction by speaking (such as "Little X"). The wake-up response time is ≤0.5 seconds. Command Interaction and Feedback: The voice recognition module 200 receives commands through the microphone hole 180. After the noise reduction pickup unit and audio processing module 300 filter background noise (such as noise from home appliances), the commands are transmitted to the cloud AI platform through the wireless communication module 400. The cloud response result is played back through the audio output module 500 (in conjunction with the front radial sound holes) as feedback voice (such as "the living room light is on"). The volume is automatically adjusted according to the ambient noise (5-85 decibels).

[0139] III. Daily Operation and Maintenance: Function Key Auxiliary Operation: Volume Adjustment: Manually adjust the output volume using the knob or gear adjustment key, or use voice commands "increase volume" or "decrease volume"; Mode Switching: Press and hold the communication button for 3 seconds to switch network modes (e.g., 2.4GHz / 5GHz dual-band switching) to ensure communication stability in complex environments. Charging and Battery Life: Connect the power adapter via the Type-C interface 150 for charging. The status indicator 160 displays the charging progress (e.g., flashing red indicates charging, solid green indicates fully charged); the power management module 600 supports energy-saving mode, automatically entering low-power standby when idle to extend battery life. Troubleshooting: If the voice interaction is abnormal (e.g., no response), insert a tool through the top reset hole 170 and press and hold for 3 seconds to reset the device and restore factory settings; if the microphone malfunctions, the status indicator 160 will flash as an alarm, requiring checking if the microphone hole 180 is blocked or contacting maintenance.

[0140] IV. Installation and Placement: Versatile Installation: Utilize the bottom mounting holes to adapt to mounting components (such as wall mounts, desktop bases), enabling wall-mounted installation, desktop placement, or vehicle mounting; Environmental Adaptability: Avoid use in environments with strong magnetic fields or extreme temperatures (outside of -10℃ to 50℃), ensuring that the microphone hole 180 and the sound output array 140 are unobstructed, guaranteeing sound pickup and audio output performance.

[0141] Through the above steps, users can quickly deploy terminal devices and interact efficiently. Combining the dual operation logic of "voice + physical buttons", it adapts to the convenient use needs of various scenarios such as smart homes and industrial control.
