Thomas Edison improved the telephone by seeing that the original transmitter used a magnate. Edison increased the signal by introducing a carbon battery.
He invented the light bulb, telephone transmitter, and fluoroscope. :)

Thomas Edison did not invent the telephone.
On 12 March 1877 Edison discovers that pressure is sufficient to capture voice for transmission to electrical signals. He received three patents in 1892 for the carbon transmitter he designed for the American Speaking Telephone Company.
No. Alexander Graham Bell invented this Telephone. Thomas Edison just wanted to be known better.
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.
