How was the first telephone evolved?
The first telephone was invented by accident when alexander and his assistant Thomas A. Watson was trying to invent a device that could send more than on telegram at the same time. In Alexander's making there was a set of spring-steel reeds working with the receiving set in one room, Thomas was in the other room. Bell plucked the steel to make a vibration and it also produced a twanging sound, when Bell came in and asked Watson to do the same, when he did it also made a vibration over the magnet and it caused a strong flow through the steel wire in bell’s room. The next day the first telephone was made and the voice sounds could be recognized over the telephone line.
