INTRODUCTION

Puts sound wherever you want, similar to flashlight.
Uses the directional property of ultrasonic waves.
Forms a beam like audio wave with the help of ultrasonic energy.
Air itself converts it into audio form.


WHY AUDIO-SPOTLIGHT?


Smaller the wavelength, lesser the wave angle.
Audible sound is the mixture of 2cm to 17mtr.
A loud speaker several times bigger than the wavelength can create a focused beam.
So audio-spotlight is used to focus the audio waves.


COMPONENTS and SPECIFICATIONS


Consists of thin transducer array, signal processor and amplifier.

AMPLIIFIER-
Worldwide standard power input.
Multi-channel input.


WORKING

TRANSMISSION
Similar to the idea of amplitude modulation.
Audio wave mixed with ultrasonic carrier wave and forms a hybrid wave.
Resulting hybrid wave transmitted.


CONLUSION


Being the most radical technological development in acoustics since the coil loudspeaker was invented in 1925... The audio spotlight will force people to rethink their relationship with sound…”
So we can conclude- Audio Spotlighting really “put sound where you want it” and will be “A REAL BOON TO THE FUTURE.”
