  1. WIRELESS HEADPHONES USING INFRARED RAYS • Submitted by: • VAMSI CHANDRA-ES12B1012 • GOKUL ARVIND-ME12B1017 • R.SHASHANK-EE12B1026

  2. Principle • This wireless communication system transmits sound or music signals through I.R Rays. • The intensity changes with the amplitude of the sound signal. • The variation in the intensity of I.R rays is converted into a variation in the voltage level by using a solar panel. • The voltage variation on the solar panel is amplified by a low-voltage audio power amplifier and reproduced by a speaker.

  3. Requirements: • Capacitors • Integrated Circuits • Potmeter • Resistors • IR receiver and transmitter

  4. WORKING OF THE MODEL • TTHE MODEL CONSISTS OF TWO CIRCUITS • TRANSMITTER CIRCUIT • RECEIVER CIRCUIT Both the transmitter and receiver circuit are built around IC LM386,powered by a 9V battery.

  6. RECEIVER CIRCUIT

  7. Applications: • This system can be used in industrial applications. • This system can be very useful in portable musical appliances. • An alternative for this system is the use of Bluetooth, since it can be used to increase the range of transmission. • Due to transmission of data wirelessly ,it can enormously decrease the amount of connections using wires.

  8. Advantages: • Simple in construction. • Easy to maintain and repair. • Comparatively the operation cost is less. • Efficient and low cost design. • Low power consumption. • Alternative for Bluetooth. • Disadvantages: • There might be disturbance in the output during transmission via I.R due to external factors.
