Set the situational action module 25 to the following one including LED light-emitting lamp group 250, somatosensory vibrator 251 or a combination thereof, and; S804 step 4. When the control key 111 is actuated, the display area of the operation interface 11 will show its corresponding situational effect item, and the situational effect generator 20 will receive live sound at the same time , let the situational action module 25 generate one of the following relative situational actions, including ambient LED lighting and flashing, ambient somatosensory vibration, or making both of them appear at the same time.

In this way, the real-time sound reception situational effect generation system of this creation can transmit the lighting control command signal and capture the live music signal through the 360-degree space of the live speaker, so as to achieve the characteristics of one-to-many broadcasting, no interference, and no delay. It is widely used in various parties, concerts, movie theaters, or nightclubs, etc., to effectively transmit LED lighting effects and experience the vibration of the sound experience, reaching the highest level of immersive entertainment.

During application, as shown in Figures 1 to 6, there will be a variety of manipulation keys 111 on the operation interface 11 of the creative situational effect controller 10 to provide single selection or multiple selection of different light signals to control the LED to generate a monochromatic constant Bright or flashing, or multi-color constant bright flashing, or mixed color breathing color and other different types, to Combining lights with different environments, dynamic effects can also be used in the form of marquees to make lights run in each area.

The scene encoding signal 15 forming the ARGB sound waveform can be a WAV file, but it is not limited thereto. In this way, the sound can be released into the first audio signal through the mixer 12 of the concert center console and the loudspeaker 13 on the spot. When the scene effect generator 20 at the receiving end receives the first audio signal, it will perform fast Fourier series conversion according to the continuous waveform and perform real-time comparison. When the comparison finds that the serial database contains the preset ARGB waveform When any item is selected, a first control signal will be generated corresponding to the actuation module 25 of the driving situation, so as to generate the corresponding ARGB LED lighting effect.

Specifically, when the ARGB code sound wave waveform of the situation encoding signal 15 is played out by the on-site speaker 13, the on-site situation effect generator 20 can receive this specific audio signal through the microphone radio module 21. For audio, the MEMS microphone using semiconductor manufacturing process has excellent radio frequency effect, and the lowest receiving frequency is 6Hz, which can play a wide-area radio effect. When it is applied, it can be used as a single microphone for radio reception, or it can be used as multiple array microphones, so that the surrounding sound can be effectively heard. Collect, and then filter the audio through the audio amplification and filtering circuit to produce an effective frequency range, and then convert it into an I ² S digital signal through the analog/digital converter 222, and enter the digital signal processor 223 for spectrum comparison. And the MCU 224 inside the signal processor (Microcontroller Unit) is called "microcontroller unit" in Chinese to continuously perform signal comparison operations. When it is found that there is a leading indicator in the audio data sequence and it is consistent with a certain lighting control command data string , the first control signal of a group of LED control commands is generated internally, and sent to the LED lighting group 250 to activate the ARGB light bar controller, and emit corresponding ARGB LED lights.

Through this effective control method, each situation coding signal 15 has an LED control instruction, and this system can make various special situations on the spot at will, whether it is a single color, mixed, or special flash point effect, so that The situation coded signal 15 can be effectively mixed with the live performance sound through the live mixer 12, but it can also be distinguished from the live music. Whether it is singing, played alone or mixed in the music, it can perfectly achieve the purpose of controlling the emission , so that the situational effect generator 20 at the receiving end emits different corresponding colors accordingly.

For example, the host at the concert said: Let us pay tribute to the Ukrainian people now. After pressing 111 on a control button, the signal will be decomposed and recognized immediately. In the corner, at this time, audiences wearing a device with a situational effect generator 20 on the scene, the ARGB light bar of the LED light group 250 on the device will display the Ukrainian in blue on the top and yellow on the bottom. The color of the national flag can instantly drive the interactive atmosphere of the scene, but it is not limited to this. It can also be used to pay tribute to the national flags of different colors for interactive display. Or in concerts or nightclubs, all audiences are equipped with situational effect generators 20, and can receive the control of situational coded signals 15 transmitted from the on-site control room at any time, and the situational effect generators 20 of all audiences will instantly present the same luminescence Effect, along with the rhythm of the music, it shows different lighting changes of the corresponding environment atmosphere, and then presents a shocking visual effect.

In addition, the bass band of the live music can be converted into corresponding shock waves by using the microphone to collect sound on the spot, and the shock waves can be transmitted to the human body through the somatosensory vibrator 251 . The two parts of LED lighting effect and somatosensory vibration can be combined or implemented separately to apply to entertainment venues such as concerts, movie theaters, or nightclubs. The creative situation effect generator 20 is applied as a wearable device, so that users are not limited by wired or bluetooth wireless transmission, as long as they are in a concert, movie theater, nightclub or any place with music, they can receive the surrounding environment in real time Music, this ARGB LED lighting effect combined with situational somatosensory dual effects can enable users to obtain the best immersive experience.

In summary, the novelty and practicality of this creation fully meets the requirements of a patent, and an application for a new patent is proposed. However, the above is only a preferred embodiment of this creation, and should not limit the scope of implementation of this creation; therefore, all equivalent changes and modifications made in accordance with the patent scope of this creation and the content of the creation manual should be It is within the scope covered by this creation patent.
