Product Details
Description:
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.
Parameter:
Infrared transmitter
Operating voltage: 12V
PCB size: 19 * 25mm
Infrared receiving end
Operating voltage: 4 ~ 12V
Driver Speaker: 0.5W-10W Speaker 1
PCB size: 17 * 39mm
Circuit Theory:
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

I was trying to figure out if what frequency this uses? I have a set of IR headphones for the car entertainment system that my kids like but wanted to adapt these headphones to be used with Cell phone or MP3 player. Basically want to use the transmitter to send audio directly to my IR headphones. It has been a struggle to get my kids to wear headphones. My headphones use these IR Frequency: 2.3mHz (Left) , 2.8mHz (Right) I have been looking for an inexpensive solution and this looks promising but cannot figure out what frequency this kit uses for modulation and if it might be able to be changed? -
