[0002] As people's living standards improve, entertainment and interactive products are gaining increasing attention. These products not only provide entertainment but also promote user health and social interaction. For example, interactive toys that generate sounds by blowing air and trigger corresponding lights or sound effects not only add fun to the experience but also improve the user's lung capacity and enhance the interactive experience between users.

[0003] Most common entertainment products on the market currently offer only single functions, such as triggering lighting or sound effects independently. These products lack multi-functional integration and depth of user interaction. This results in a monotonous entertainment experience and a failure to fully stimulate user engagement and interactivity. Furthermore, many existing products fail to consider user health needs, particularly in areas such as improving lung capacity and respiratory function. Utility Model Content

[0004] To address these issues, the present invention provides an LED light control system based on airflow sound detection. This system can trigger varying numbers of LED lights based on the force and duration of a user's blowing. This entertainment product, accompanied by sound feedback, not only increases user enjoyment but also virtually strengthens the user's lung capacity and improves respiratory function. More importantly, the product also features features like recording, voice changing, and the playback of music or stories, increasing user interactivity and enhancing the diversity and appeal of the entertainment experience.

[0022] Figure 2 This is a circuit diagram of the utility model. DETAILED DESCRIPTION

[0023] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0024] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0025] like Figure 1 and Figure 2 As shown, the utility model relates to an LED light control system based on airflow sound detection. The system includes a microphone, a main control integrated circuit, multiple LED lights, an audio playback circuit, a speaker, a switch, a first button, and a second button.

[0026] In one embodiment of the present invention, the microphone is configured to receive sound signals generated by a user blowing air. The microphone is electrically connected to a main control integrated circuit (IC), which receives and processes the sound signals from the microphone. Based on the duration of the sound signals, the IC controls the number of LED lights that illuminate.

[0027] Specifically, in this embodiment, when the user blows continuously for 2 seconds, the main control integrated circuit controls the lighting of the first LED light; when the blowing continues for 4 seconds, the main control integrated circuit controls the lighting of the second LED light; and so on. For every additional 2 seconds of continuous blowing, the main control integrated circuit controls the lighting of a new LED light. In this way, by controlling the length of blowing, the user can light up different numbers of LED lights, increasing the interactivity and entertainment of the system.

[0028] The system further includes an audio playback circuit connected to the main control integrated circuit. After the user stops blowing, the audio playback circuit generates an audio feedback signal based on the number of illuminated LED lights and plays it through the speaker. For example, when two LED lights are illuminated, a preset prompt tone or music plays; when three or more LED lights are illuminated, different sound effects can be played to enhance the user's entertainment experience.

[0029] The system is equipped with a switch to control the power on and off of the entire system. Users can turn the system on or off with this switch, which is easy to operate.

[0030] To increase the system's versatility, the present invention also includes two buttons. The first button switches between LED light mode and recording and voice-changing playback mode. When the system is in recording and voice-changing playback mode, the main control integrated circuit records the sound signal received by the microphone, performs voice-changing processing, and then outputs it through the speaker.

[0031] The second button is used to switch between music playback mode and story playback mode. In this mode, the main control integrated circuit reads a pre-recorded music or story audio file from the storage unit and plays it through the speaker. The storage unit can store multiple types of audio files, and users can choose different content to play according to their needs.

[0032] like Figure 1 and Figure 2 As shown, the circuitry of this utility model's LED light control system based on airflow sound detection operates primarily on the reception, processing, and feedback of sound signals. The system uses a microphone to capture the sound signal generated by the user's breath, which is then input into the main control integrated circuit (IC) as an analog electrical signal. Upon receiving the signal from the microphone, the IC first converts the analog signal into a digital signal using its internal analog-to-digital converter (ADC), which is then analyzed and processed.

[0033] When the user begins blowing, the microphone captures the acoustic signal of the airflow. As the user continues blowing, the main control integrated circuit calculates the duration of the acoustic signal and, based on pre-set logic, controls the LEDs connected to the different output ports to illuminate sequentially. For example, blowing for 2 seconds will illuminate the first LED, blowing for 4 seconds will illuminate the second LED, and so on, until the user stops blowing or the maximum number of LEDs set by the system is reached.

[0034] After the user stops blowing, the main control integrated circuit generates an audio feedback signal corresponding to the number of illuminated LEDs. The audio signal is converted to an analog signal by a built-in digital-to-analog converter (DAC), then amplified by the audio playback circuit, and finally output by the speaker. The audio feedback can take the form of a simple prompt tone, a musical clip, or a pre-stored story content, depending on the system's operating mode.

[0035] The system also includes a button control function. The user can use the first button to switch between LED lighting mode and recording and voice-changing playback mode. In recording and voice-changing playback mode, the main control integrated circuit simultaneously records the user's voice input through the microphone, processes the voice, and finally plays it through the speaker. The second button is used to switch between music playback mode and story playback mode, allowing users to choose to play pre-stored music or story content.

[0036] In addition, the system controls overall power management through a switch. When the switch is turned on, power is supplied to all circuit modules and the system enters operation; when the switch is turned off, the system is powered off and stops working, ensuring energy conservation and safety.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
