The Telephone

The phone before an iPhone

The Invention Story

Alexander Graham Bell invented the telephone in 1876. He started out trying to make the telegraph better, but later decided he would be able to send the sound of a human voice over his new telegraph. One day, he heard the sounds of plucked reeds coming across the wire from his partner, Thomas Watson. After some tweaking, he was able to send sounds. They were issued a patent on March 7, 1876 and a few days later while they were working, Thomas Watson heard Alexander Bell's voice come over the wire saying, "Mr. Watson, come here. I want you!" because he had spilled battery acid on his clothes. This accident was soon forgotten in the excitement of the new success.

How it works

Telephones send sounds through electric or radio signals. The microphone picks up sounds and changes them into these signals. A speaker on the other end collects the signals and changes them back into sounds. To dial, you press a series of buttons that a computer recognizes as a phone number and sends the call to that phone. Cellular phones have a circuit board that controls other functions of the phone. Telephones are connected to a wire or the internet that allows them to make calls.

Benefits of the Telephone

The telephone has many benefits. It allows people to stay in contact with others who are far away and talk to them instantly. You can share news right away rather than waiting for a telegraph or letter to be sent. Over the years, telephones have evolved greatly. They went from being large and hooked to wires to small and wireless. Now almost everyone has a phone and they are much faster than they used to be. The telephone is a very changing invention.
