How did Thomas Edison improve the telephone that Alexander Graham Bell invented?
Bell & Watson's telephone had a parchment diaphragm. Thomas Edison recognized that if the diaphragm were replaced with a conductive medium it would have far greater transmission strength, and possibly better clarity. Edison developed a compressed carbon disc which was indeed superior to Bell's parchment design, and later improved it by baking the carbon. Apparently this later version was used in telephones for much of the 20th Century.
