Alexander Graham Bell

Bell was curious about things for his whole life. He grew up with a Mother who was deaf, and he later married Mable Hubbard, who was also deaf. They were his inspiration for the telephone.

Bell discovered how to make his phone work by accident; his assistant Thomas Watson accidentally plucked a reed that allowed Bell to hear the overtones needed to hear speech from the other end of the phone. In modern day phones, the transmitter sends electrical signals that are changed from sound waves to the phone on the other end.

At first, the telephones were diverse. They could be dynamic, which is when the coil vibrates around the diaphragm, or they could even use a liquid transmitter.

There are several pieces in a telephone. There is a microphone for talking into and an earphone for listening. Phones also have a dial, which can be on the base of the phone of on the handset.

Telephones have become more and more advanced since they were invented in 1876. They can now be used for taking pictures, texting, calendars, entertainment, and so much more. They will only come more and more advanced in the near future.
