The advantage of this technique is that investment required for communication purposes will reduce drastically. The total cost for re-wiring of audio transmission is reduced and cost of the adapter is only Rs. 15.This innovation has the potential to offer a new low cost solution to related issues in communication technology.
Using this technique, audio output from a tape recorder or radio is connected to a plug adapter in which the live point is disconnected. Now the audio signals are available in the neutral and earth wires. The output of the audio signals is collected through the adapter and connected to the audio output device like speakers at any other location within the house i.e., the output of the music system is inputted in the earth and neutral sockets. In whichever room one wants to hear the music, one can insert the two wires into the plug points and the speaker into the earth and neutral socket.
