Using this wireless IR Headphones circuit electronic project you can transmit audio signal using an infrared connection .This wireless IR Headphones circuit diagram electronic project is composed by two parts : transmitter and receiver . This is not an RF transmitter , so you will need to design both parts of application .
Using this infrared audio signal transmitter you can build an infrared cordless headphone , that can be very useful if is used with an TV or some other electronics device that can disturb other persons .
Without using some special devices this electronic project can be used over an 6 meters range .The transmitter circuit use an output transformer ( in reverse ) to couple the TV to the IR transmitter . T1 and T2 transformers are used to amplify the audio signal from the audio transformer .
The IR receiver module use a three stage transistor amplifier .The VR2 potentiometer is used to adjust the clarity . To have an high efficiency and a maximum range for this IR circuit direct photo-transistor towards IR LEDs of transmitter .
Both of these circuits needs to be powered by a 9 volts DC power supply .
