The basic principle of using the Red Rumble Kit is the sound caused by infrared (laser) vibration, which then receives an infrared vibration signal at the infrared receiver diode of the receiver circuit, and the signal is demodulated to achieve sound attenuation. Transmission distance can reach one meter, which can be used to make short-range wireless speakers.
Infrared receiving end
The transmitting end: the headset port, the audio signal input through the transistor Fat S8050, an infrared transmitter to drive the tube, and the audio signal is transmitted in the form of infrared.
The receiving end: the infrared receiving tube for receiving the infrared signal transmitter, converted into an audio signal through the LM386 audio amplifier chip, and the audio output signal can be amplified
