How Did Alexander Graham Bell Make The Telephone
Alexander Graham Bell was born on March 3, 1847 in Edinburgh, Scotland. Working through numerous experiments in sound and advancing his father’s work on Visible Speech for deaf people Bell acquired his education.To continue his study about the human voice he opened a workshop. He also did important work in communication for the deaf. Throughout his life he held more than 18 patents. Bell was one of the primary inventors of the telephone. Through many years of experimentation with sound waves he created the telephone. Bell got the idea from the phonautograph version that he created. The phonautograph worked by drawing sound waves so this made him think that it was possible to create electrical currents that correlated with sound waves. Bell

When Watson accidentally removed one of the reeds, Bell and Watson made a discovery. The sound that was being transmitted to Bell showed him that he only needed one reed or item that could vibrate correctly to conduct the sound(How did Alexander Graham Bell make the telephone? | Reference.com). On March 10, 1876, Bell and Watson were successful. Bell called his first phone “Liquid Transmitter.” It was a vertical metal cone with a piece of parchment extended like a drum over its narrow end at the base, in the outside of the parchment he had glued a cork with a needle inserted in it pointing into a small cup of diluted sulphuric acid. When Bell yelled into the open end of the cone his voice made the parchment vibrate and the needle moved a bit in response to a contact in the cup. The needle was wired to a battery and the motion mixed with the strength of the current transmitting between the contacts. It converted sound wave into an electric signal that traveled along a wire to a receiver. While Bell was setting up his experiment he tipped over some acid on himself. He shouted to his assistant, Watson, who had heard the
