[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Reference Figure 1-3 This utility model provides a children's watch with voice alarm, including a watch face 100 and a watch strap 200. The watch face 100 includes a watch case 101 and a display. The display includes an LCD 105 and a TP 106, realizing the display and touch functions of the watch. A decorative part 107 is provided on the watch case 101, and the display is located in the middle of the decorative part 107. The decorative part 107 enhances the appearance of the children's watch and protects the display.

[0025] In this embodiment, refer to Figure 1The watch face 100 is equipped with a power supply, a storage unit, a voice module, a positioning module, a microprocessor, and an always-on display module. The storage unit stores voice commands, electronic fence commands, and alarm commands. The voice module acquires sound in real time and compares it with the voice commands stored in the storage unit. The positioning module acquires location information in real time and compares it with the electronic fence commands stored in the storage unit. When the voice module recognizes a stored voice command or the positioning module recognizes an electronic fence command, an alarm command is triggered. The microprocessor executes the alarm command to activate the alarm on the output device, allowing the guardian to respond promptly and protect the wearer. The always-on display module controls the display to be in a closed state when the alarm command is triggered, meaning the watch interface is unresponsive, providing strong concealment and preventing intruders from becoming alerted, thus protecting children and making it more suitable for rescue.

[0026] It is understood that the voice command refers to a pre-recorded audio message, such as "My name is XXX". The voice module includes a highly sensitive microphone (such as the Minxin MG18D181) capable of continuous sound pickup in hardware, and a speech recognition algorithm based on a deep learning framework in software. Taking the PyTorch framework as an example, the steps are as follows:

[0027] 1. Speech signal preprocessing

[0028] Speech signals are analog signals, so they need to be sampled first to convert the continuous time-domain signal into a discrete numerical sequence before filtering, enhancement, noise reduction, and other processing can be performed. The TorchAud library can be used to achieve this.

[0029] 2. Speech Feature Extraction

[0030] Common methods for extracting features that represent key speech information from preprocessed speech signals include MFCC (Mel frequency cepstral coefficients), SP (spectral pairs), and LPC (linear predictive coding).

[0031] 3. Select and train a speech model

[0032] Models such as DNN (Deep Neural Network), RNN (Recurrent Neural Network) and its variants LSTM, GRU, or CNN (Convolutional Neural Network) can be selected.

[0033] 4. Text Decoding

[0034] Converting model output into text commonly uses methods such as the Viterbi algorithm and Beam Search.

[0035] The above framework can improve the accuracy of voice recognition. In actual use, after the children's watch enables the real-time voice capture function (turns on the microphone), when the wearer says "My name is XXX", the voice module recognizes the voice command and triggers an alarm command. The microprocessor executes the alarm command and transmits the alarm information to the preset contact through the communication module, which means that the alarm is activated on the output device of the preset contact, realizing the automatic alarm function.

[0036] It is understood that the aforementioned electronic fence command refers to using the watch's built-in positioning module (employing positioning technologies such as GPS, Wi-Fi, and cellular networks) to set a virtual geographical area on a mobile app. This area acts like an invisible fence. The positioning module acquires the wearer's location information in real time and compares it with the set fence area to determine whether the wearer is within the electronic fence. When the positioning module detects an electronic fence command (the wearer's location information exceeds the fence area), it triggers an alarm command. The microprocessor executes the alarm command and transmits the alarm information to a preset contact via the communication module. The alarm is then activated on the preset contact's output device, realizing the automatic alarm function.

[0037] During the alarm process, the alarm command runs silently in the background of the watch through the screen-off module settings, and the relevant interface and process are not displayed on the screen, thus maintaining a seemingly "unresponsive" state. That is, the watch interface does not react at all, which has good concealment and protects children.

[0038] In a preferred embodiment, the children's watch further includes a drowning detection module. The storage device stores drowning commands. The drowning detection module includes a water immersion detection sensor. The water immersion detection sensor has a detection area exposed on the watch case 101. When this area comes into contact with water, it generates an immersion signal, such as a voltage signal. The voltage value is linearly positively correlated with the amount of water immersed. The immersion signal is compared with the drowning commands stored in the storage device. When a drowning command is detected, the alarm command is triggered. The microprocessor executes the alarm command and transmits the alarm information to a preset contact person through the communication module. The alarm is activated on the output device of the preset contact person, realizing the automatic alarm function.

[0039] In a preferred embodiment, the children's watch further includes a heart rate detection module (such as MAX30102, VishayVEMD2704, etc.). The heart rate lens 109 of the heart rate detection module is installed at the bottom of the watch case 101 so as to make contact with the wearer's wrist. The heart rate detection module is used to detect the wearer's heart rate to understand the wearer's physical condition. The heart rate information can be displayed on the display after being processed by the microprocessor, or it can be transmitted to the output device of the preset contact person through the communication module.

[0040] In addition, the children's watch of this utility model is also equipped with a physical button 111 alarm function. An alarm button 111 is provided on the side wall of the dial 100. When the alarm button 111 is pressed, it is used to trigger the alarm command. The microprocessor executes the alarm command and transmits the alarm information to the preset contact through the communication module. The alarm is activated on the output device of the preset contact to realize the alarm function.

[0041] In this embodiment, the communication module adopts communication methods such as 4G, 5G, and Wi-Fi, and the watch is provided with a card tray 112 for storing a SIM card.

[0042] In some embodiments, the voice module further includes a speaker 108 to play sound from the watch. A PCBA 104 is disposed within the watch face 100, and the storage and microprocessor are integrated on the PCBA 104. The power source is a high-capacity battery 103, and the power source is connected to a power-saving module. The power-saving module is used to reduce the watch's power consumption. The power-saving module may employ a battery management system (BMS) to monitor the battery status in real time and improve battery efficiency and lifespan through technologies such as balanced charging and overcharge / over-discharge protection. Furthermore, a charging case 110 is disposed on the watch face 100, and the charging case 110 is connected to the high-capacity battery 103 for convenient charging of the high-capacity battery 103.

[0043] In the above embodiments, referring to Figure 3 The watch case 101 is provided with a bracket 102, which is used to install various components (high-capacity battery 103, PCBA 104, etc.).

[0044] Furthermore, a waterproof protective layer is provided on the dial 100. The waterproof protective layer can be made of a sealant or similar structure to make the children's watch waterproof.

[0045] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
