The telephone was invented in 1876, by Alexander Bell and his assistant A. Watson. He got the idea while he was working on harmonic telegraph with his partner Watson. When Watson was connecting the transmitter with the receiver, Bell heard partially the words of Watson and then he got the idea to make a device with transmitting sounds. Then, on February 14, 1876 Bell applies for the patent “improvement in telegraphy” for telephone. Bell invented the telephone by using the vibrations of a sound wave. When the sound waves reach the ear of the person at the other end of telephone they get the same effects as they would have, if they came directly from the speaker’s mouth. Itself telephone was consisted of transmitter and receiver and few wires. Transmitter transfers the sound waves to receiver, and via the wives we can hear the sound of transmitter. In June 25, 1876 Bell demonstrated his telephone in Finland on the worldwide electro technical shows.
