Edison invented and developed the carbon microphone used in all telephones along with the Bell receiver until the 1980s. After protracted patent litigation, in 1892 a federal court ruled that Edison and not Emile Berliner—was the inventor of the carbon microphone. The carbon microphone was also used in radio broadcasting and public address work through the 1920s.

Credit for the invention of the electric telephone is frequently disputed, and new controversies over the issue have arisen from time-to-time. As with other great inventions such as radio, television, light bulb, and computer, there were several inventors who did pioneering experimental work on voice transmission over a wire and improved on each other's ideas.

An illustration of one of the early telephones, known as a chemical telephone. Some used a liquid transmitter, some had a metal diaphragm that induced current in an electromagnet wound around a permanent magnet, and some were "dynamic" - their diaphragm vibrated a coil of wire in the field of a permanent magnet or the coil vibrated the diaphragm.

"When a person speaks into the transmitter, the pulsations of the air, produced by the voice, produce the slight vibrations of the diaphragm...and these vary the pressure of the platinum point on the carbon disk, and these vary the strength of the electric current, and reproduce precisely similar vibrations in the diaphragm of the receiver, at the opposite end of the line, which reproduce the spoken words." -Atkinson 1903
