The standard audio input interface can be connected to MP3, VCD, DVD, mobile phone, radio and other audio devices, and the voice input interface can be connected to an external microphone.

First, the audio signal is added to the audio processing circuit through the microphone or the same audio line for gain adjustment, and the filter circuit in the audio processing circuit filters the unnecessary audio signal, and the filtered signal is added to the selection switch, which is It is necessary to select the manual or remote control mode to switch the favorite signal. After selecting the signal, the signal is output to the thyristor trigger pin of the control output processing module. When the signal reaches a certain amplitude, the thyristor is turned on and connected. The various colored lights of the silicon control form an AC loop, which is illuminated by the current; and the lighting time is consistent with the on/off time of the thyristor, and the on/off state of the thyristor is controlled by the music rhythm, thus generating a light The effect of brightness change is consistent with the strength of the music rhythm.
