What connection does the bell telephone and microphone have together?
Alexander Graham bell developed a telephone transmitter called a ' butter pat' microphone.Encased in wood they looked like a dairy stamp. One was held in the hand in front of the mouth and one against the ear. They were not very sensitive and Thomas Edison's carbon button microphone won out and Bell's receiver was retained.

Both Emile Berliner and Thomas Edison applied for patents on the carbon microphone in 1877.
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.
Who perfected the lightbulb by adding a carbon-based filament in 1881?
Lewis Howard Latimer perfected it but Thomas Edison invented it
Was the light bulb Thomas Edison's first invention?
The first practical incandescent light bulb. Edison and his team of researchers in Edison's laboratory in Menlo Park, N.J., tested more than 3,000 designs for bulbs between 1878 and 1880. In November 1879, Edison filed a patent for an electric lamp with a carbon filament.
