S801, step 1, corresponds each control key 111 to the situational effect item, and corresponds to a situational coding signal 15 simultaneously, so that the situational coding signal 15 is composed of multiple frequencies, and the situational coding signal has at least two or more different frequency bands, the frequency bands are separated by a time interval, and the situational coding signal is coded by different gain values:
S802, step 2, wherein the situational coding signal 15 is a plurality of frequency sinusoidal waves with a time interval between 100 mm and 300 ms, and an equal interval of a blank time tag between 100 mm and 500 ms which is provided before and after the plurality of frequency sinusoidal waves of the situational coding signal 15:

In this way, The system for generating situational effects of live real-time sound receiving of the present invention, the lighting control command signal is transmitted through the 360 degrees space of the live speaker 13 and capture the live music signal to achieve the features of the one-to-many broadcast, no interference, no delay, which can be widely used in various parties, concerts, movie theaters, or nightclubs, etc., effectively transmit LED lighting effects and immersive experience to feel the somatosensory vibration and reach the highest level of immersive entertainment.
During application, as shown in
In this way, when the color of the control key 111 is pressed, there will be a display area corresponding to the color of the selected LED and its dynamic preview display effects that are displayed on the operation interface 11. The specific changeable color combination of the selected light number automatically corresponds to generate an ARGB (ADDRESSABLE RGB) sound wave code of the exclusive situational coding signal 15 of the present invention, which can be selected from two frequency bands or more than three frequency bands, and utilizes each frequency band to be continuous without interval, or its interval between each other is difference in size and gain, such as 2 dB, 3 dB, 4 dB. It is used as a coding method to generate a sinusoidal waveform, the best time interval is around 200 mini seconds, but it is not limited to this.
It cannot be ignored that each music has a certain range. For example, a certain music contains 80 Hz. When the situational coding signal 15 with the same 80 Hz is arranged therein, the sound of the lighting control command of the situational coding signal 15 can be effectively merged together by the live music, and will not be covered by the live music to be invalid. In addition to using the foregoing special multi frequency situational coding signal 15 control command, the blank time tag can also be arranged before and after the situational coding signal 15 like 100 ms., but it is not limited to this. In this way, it can be ensured that the commands of the situational coding signal 15 are compatible and combined with the live music and will not be covered, and simultaneously can be correctly interpreted (decodes and reads) to achieve the purpose of the remote real-time control of the light signal.
The situational coding signal 15 forming the ARGB (ADDRESSABLE RGB) sound waveform can be a WAV file, but it is not limited to this actually. In this way, the sound can be released into the first audio signal through the sound mixer 12 of center console of the concert and the speaker 13 on the spot. When the situational effect generator 20 at the receiving end on the spot that receives the first audio signal, it will perform a fast Fourier series conversion according to the continuous waveform and perform a real-time comparison. When the comparison is found any item that is the serial database contains the preset ARGB (ADDRESSABLE RGB) waveform. The first control signal will be generated corresponding to drive the situational action module 25, so as to generate the corresponding ARGB (ADDRESSABLE RGB) LED lighting effect.
Specifically, when the ARGB (ADDRESSABLE RGB) code sound wave waveform of the situation encoding signal 15 is played out by the loudspeaker 13 on the spot, the situational effect generator 20 on the spot can receive the specific audio through the microphone sound receiving module 21. Wherein the microelectric machanic system (MEMS) microphone using the semiconductor process has an excellent sound receiving frequency effect, the lowest receiving frequency is 6 Hz, and it can play a wide range sound receiving effect. When it is applied, it can be used as a single microphone for sound receiving, or it can be used as a multiple array microphone that the peripheral sound can be effectively collected, then the audio will be filtered through the audio amplification and filtering circuit to produce an effective frequency range, then converted into an I2S digital signal through the ADC analog to digital converter 222, then entered into the DSP digital signal processor 223 to make a spectrum comparison, and use the MCU (micro control unit) 224 inside the signal processor to continuously execute the signal comparison operation. When it is found that there is a leading indicator in the audio data sequence and is consistent with a certain lighting control command data string, a first control signal of a set of LED control commands will be generated internally. The control signal is sent to the LED lighting lamp group 250 to activate the ARGB (ADDRESSABLE RGB) light bar controller and emit corresponding ARGB (ADDRESSABLE RGB) LED lights.
Through this effective control method, each situational coding signal 15 has an LED control command, and the system can freely make various special situations on the spot, whether it is monochromatic, mixed, or special flash twinkle effect, so that the situation coded signal 15 can be effectively mixed with the live performance sound through the live sound 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 be perfectly achieved to control the emission purpose, let the situational effect generator 20 as the receiving end that emit different corresponding colors accordingly.
For example, the host at the concert said: Let us pay tribute to the Ukrainian people together now. After a control key 111 is pressed down, the signal is decomposed and recognized at once. For example: code A1+C2, the sound is mixed therewith, then spread to every corner. At this time, audiences wearing devices with situational effect generator 20 will display the colors of the Ukrainian national flag on the upper blue and lower yellow of the ARGB (ADDRESSABLE RGB) light bar on the LED lighting lamp group 250 on the device, which will instantly drive the interactive atmosphere on the spot. But it is not limited to this, and it can also be used to pay tribute to the national flags of different countries for interactive display. Or in concerts or nightclubs, all audiences are equipped with situational effect generators 20, and can receive the control of situational coding signals 15 transmitted from the control room on the spot 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, through the microphone receives sound on the spot, the bass range of live music can be converted into corresponding shock waves, 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 which can be combined or implemented separately to apply to entertainment venues such as concerts, movie theaters, or nightclubs. The situational effect generator 20 of the present invention is applied as a wearable device, so that the user is not limited by wired or Bluetooth wireless transmission, and can receive the surrounding environment in real time as long as he is in a concert, a movie theater, a nightclub or any place with music, this ARGB (ADDRESSABLE RGB) 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 the present invention fully meets the requirements of the patent, and an application for a patent for invention is proposed. But the foregoing is only a preferred embodiment of the present invention, and should not limit the scope of the present invention: so all equivalent changes and modifications made according to the patent scope of the present invention and the contents of the invention specification should be within the scope covered by the patent of the present invention.
