[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0039] The intelligent plush toy existing on the market is driven by a circuit module to drive a motor to drive an internal mechanical structure, so that some positions of the toy can automatically perform some actions and speak some simple voice phrases and music. However, because of the mechanical driving structure, the movable function is increased, resulting in the following problems:

[0040] The plush product is more a movable toy product, and some action and voice play is used to realize simple interaction with consumers. Most of the products belong to a kind of children's toys, which cannot meet the needs of adults and cannot provide some functions such as sleep guardianship required by adults, especially single young people who need more companionship.

[0041] Based on this, the utility model provides a kind of light control system, based on external environment brightness and sound, control light brightness switch to low brightness condition, and control sound module to play sleep aid white noise, to meet the need of sleep guardianship in this way.

[0042] In addition, the current plush product cannot provide some emotional soothing, emotional companionship and other functions required by adults. The intelligent dialogue of the product is relatively single, and simple communication is carried out only by language, and some interaction and language communication cannot be carried out.

[0043] Based on this, the utility model provides a kind of intelligent toy, which collects the voice of user by using voice acquisition module, and plays corresponding offline voice by control chip, to realize interaction with user.

[0044] The following will be described in combination with Figs. 1-3The light control system of the first aspect of the utility model and the intelligent toy of the second aspect of the utility model are illustrated in detail.

[0045] According to the embodiment of the utility model, first, a light control system is provided, in combination with Fig. 1 As shown in the figure, it comprises a brightness acquisition module 108, a voice acquisition module 109, a control chip 104 and a light module 110, the output ends of the brightness acquisition module 108 and the voice acquisition module 109 are connected to the input end of the control chip 104 respectively, and the output end of the control chip 104 is connected to the controlled end of the light module 110. The brightness acquisition module 108 is used for detecting the brightness of the surrounding environment and converting the brightness signal into an electric signal. The voice acquisition module 109 is used for collecting the sound in the surrounding environment and converting the volume signal into an electric signal. The light module 110 is used for adjusting the light brightness. The control chip 104 is used for receiving the electric signals transmitted by the brightness acquisition module 108 and the voice acquisition module 109 and judging whether the corresponding operation is triggered according to the preset condition.

[0046] The brightness acquisition module 108 collects the brightness of the surrounding environment and feeds back the brightness signal to the control chip 104, the control chip 104 compares the brightness signal value transmitted by the brightness acquisition module 108 with the set brightness threshold value and judges whether the surrounding environment is darkened. When the brightness signal value transmitted by the brightness acquisition module 108 is lower than the brightness threshold value, the control chip 104 judges that the surrounding environment is darkened, the voice acquisition module 109 collects the sound in the surrounding environment and feeds back the sound signal to the control chip 104, and the control chip 104 judges whether the sound in the surrounding environment is the uniform breathing sound. When the control chip 104 judges that the sound in the surrounding environment is the uniform breathing sound, the control chip 104 controls the light module 110 to reduce the light brightness.

[0047] The above-mentioned light control system, through the cooperative work of the brightness acquisition module 108 and the voice acquisition module 109, can be applied to the intelligent plush toy, so that the intelligent plush toy can automatically adjust the light brightness when detecting that the surrounding environment is darkened and identifying the uniform breathing sound. This function is particularly suitable for young single people and can provide them with soft light companionship at night, which helps to relieve the sense of loneliness and improve the sense of security. Unlike the traditional intelligent plush toy with mechanical structure, the utility model does not rely on the motor and mechanical structure to realize the interactive function, not only reduces the complexity and potential failure points of the product, but also makes the product more portable, soft and more suitable for adult use.

[0048] The light control system described above, through the combination of the brightness acquisition module 108 and the voice acquisition module 109, can intelligently perceive the changes in brightness and sound around it and make corresponding responses based on this information. For example, at night when the room becomes dark and uniform breathing sounds of the user are detected, the light brightness is automatically reduced to avoid sudden strong light interfering with the user's sleep. Since sensor-driven rather than mechanical-driven is adopted, the overall system has lower power consumption, prolongs the product's battery life, and improves the user's experience.

[0049] The light control system described above can respond to user voice commands through the voice acquisition module, such as playing soothing music or stories, further enhancing the product's interactivity.

[0050] In some embodiments, the control chip 104 is built-in with a digital signal processor (DSP) which is used to preprocess the sound signal, extract time domain and frequency domain features, classify the features, and determine whether it is uniform breathing sound.

[0051] More specifically, the digital signal processor includes a preprocessing module, a feature extraction module, and a feature classification module. The preprocessing module is used to filter and denoise the original audio data before feature extraction to remove noise and optimize signal quality. The feature extraction module is used to extract time domain and frequency domain features from the preprocessed sound signal. Common methods for extracting time domain features include short-time energy and zero-crossing rate. Common methods for extracting frequency domain features include Fourier transform method, which converts time domain signal to frequency domain signal to analyze its frequency components. The feature classification module is used to classify the extracted time domain and frequency domain features using trained machine learning models. These models can be trained with a large amount of labeled data to distinguish different types of breathing sounds (such as uniform breathing, non-uniform breathing, speaking sound, etc.). Further, when the digital signal processor determines that the external sound is uniform breathing sound, it triggers the corresponding operation to control the light module 110 to reduce the brightness; if the digital signal processor determines that the external sound is not uniform breathing sound, it maintains the original state or further analyzes.

[0052] In this embodiment, compared with simple volume detection, the digital signal processor can effectively distinguish background noise and other non-breathing sounds through deep analysis of the sound signal, thereby improving the accuracy of breathing sound recognition and reducing the possibility of misjudgment. When the digital signal processor confirms that the sound in the surrounding environment is uniform breathing sound, the control chip 104 triggers the light module 110 to reduce the brightness. This function is particularly useful at night, as it can automatically dim the light after the user falls asleep, avoiding strong light interfering with sleep and providing a more comfortable sleep environment.

[0053] In some embodiments, the light control system further comprises a sound module 105. When the control chip 104 determines that the sound in the surrounding environment is uniform breathing sound, the control chip 104 controls the sound module 105 to start playing pre-stored sleep-aiding white noise. White noise is a kind of sound signal with wide frequency spectrum, which can mask other noises in the environment, helping users fall asleep faster and maintain good sleep quality. The volume and frequency of white noise can be adjusted according to user preferences to ensure the most comfortable sleep-aiding effect.

[0054] In this embodiment, the light control system realizes intelligent recognition and response to breathing sound by integrating the sound module 105. When the control chip 104 determines that the sound in the surrounding environment is uniform breathing sound, the system automatically plays sleep-aiding white noise, thus creating a more comfortable and quiet sleep environment and improving the overall user experience.

[0055] More specifically, the sound module 105 includes a power amplifier module and a loudspeaker. The power amplifier module is responsible for amplifying the audio signal from the control chip 104 so that it has enough power to drive the loudspeaker to produce sound. The loudspeaker is the sound-producing component of the sound module 105, responsible for converting the electrical signal output by the power amplifier module into sound waves and delivering them to the user. The sound module 105 is connected to the control chip 104 through a DAC (Digital-to-Analog Converter), which is used to convert the digital audio signal generated by the control chip 104 into an analog audio signal so that the power amplifier module and the loudspeaker can process and play these audio signals.

[0056] In some embodiments, the control chip 104 has a built-in timer. When the control chip 104 detects uniform breathing sound in the surrounding environment through the digital signal processor (DSP), the system enters the sleep-aiding mode. The control chip 104 sends instructions to the light module 110 to gradually reduce the light brightness, while the control chip 104 controls the sound module 105 to play sleep-aiding white noise. When the brightness of the light module 110 is reduced to a predetermined level and the sound module 105 starts playing white noise, the built-in timer is activated and starts counting. The timer can be pre-set for a certain period of time, and when the timer reaches the set time, the control chip 104 sends instructions to the light module 110 to completely turn off the light. At the same time, the control chip 104 also sends instructions to the sound module 105 to stop playing sleep-aiding white noise.

[0057] In this embodiment, through the built-in timer, the control chip 104 can maintain a low light brightness and sleep-aiding white noise for a certain period of time after the user falls asleep, and automatically turn off the light and stop playing white noise when the pre-set time is reached. This not only improves the intelligence level of the system, but also ensures that the user has a more comfortable and quiet sleep environment at night, while avoiding unnecessary energy consumption for a long time.

[0058] In some embodiments, the brightness collection module is an optocoupler resistor. The optocoupler resistor is a kind of photoelectric conversion element, which can convert the received light intensity into a corresponding resistance value change. When the intensity of ambient light changes, the resistance value of the optocoupler resistor will change accordingly. The optocoupler resistor is transmitted to the control chip through the ADC signal.

[0059] In some embodiments, the voice collection module is a MIC. The MIC is transmitted to the control chip through the ADC signal.

Posture sensor 102 includes three-axis gyroscope and three-axis accelerometer. Three-axis gyroscope is used to measure the rotation angle of toy main body 200 in three axial directions, and provides accurate posture information.
