This paper deals with one of those suppressed inventions with great capabilities and brilliant idea. Neurophone is one such fascinating device. It allows human to hear using their skin without their auditory system. The key to the Neurophone is the stimulation of the nerves of the skin with a digitally encoded signal that carries the time-ratio encoding that is recognized as sound by any nerve in the body. This device is known to increase the brain activity with regular usage. It has great potential to be used as a learning device since it stores information in long term memory. In this paper the evolution of Neurophone, its working, components used for its construction, future developments are discussed.
