Design of Optical Communication Headset Based on Visible Light Communication Technology.

To overcome the disadvantages of existing infrared earphones and Bluetooth earphones, such as poor stability, low performance and much interference, an optical communication headsetis designed based on visible light communication technology. The photoelectric transmission system, which takes the visible light as the carrier to transmit the audio signal, is composed of the transmitting part and the receiving part. The modulation and demodulation of signal is realized by using a single-chip microcomputer. Experimental results show that the visible light headset system has the advantages of stability, flexibility in operation, high signal strength, and adjustable volume.
