Report of IR Music Transmitter & Receiver
Infrared is the most commonly used wireless data transfer medium for limited range, and we already covered about simple IR Transmitter and Receiver circuit. Using this circuit you should be able to play songs from your IPod, mobile or computer to an external speaker without having to connect them directly though an AUX cable. The circuit comes with many limitations and there are better ways like Bluetooth to play songs wirelessly, hence this article only aims to help you understand simple audio circuits and at the same time have fun building it. Also the circuit of this project is simplified as much as possible to keep things simple and reliable to make the build easier, so this should be a great weekend project to build and learn along with your friends. The principle behind the circuit is that, we will have two individual circuits. One is the transmitter circuit and the other is the receiver circuit, the transmitter circuit will be connected to the 3.
With the eight octaves music creating infinite notes and it is really amazing and pleasing thing. Music is something unique and universal. In our daily life music become our part of life. Every day we enjoy the music at any time that may at home, occasion, parties or at office while working also. While working when we feel tiered and if we listens music it gives much relief than any other and makes us refresh to continue the day with very energetic.
Using this circuit, audio musical notes can be generated and can be heard up to a distance of 10 meters. The receiver can be placed at a maximum distance of 1 meter from the transmitter without any considerable noise interference.
This IR audio link is able transmit audio signals for short distances. The audio signal which is to be transmitted is applied at the base of the transistor in Transmitter section. An 8 speaker or head phone is connected at the receiver section to listen to the transmitted signal. Wireless Audio is already a technically advanced field where Bluetooth and RF Communications are the main technologies although most commercial audio equipment works with Bluetooth. Designing a simple IR Audio Link Circuit would not be beneficial when compared to the existing technologies but it surely will be a learning experience about wireless audio transfer. The reason for not being beneficial is the fact that unlike Bluetooth, IR is line-of-sight communication i.
