Topic: The Evolution of the Telephone
Presenters: Paul Weeks
Summary: This presentation is about the evolution of these telephone systems from the original rather primitive telephones to the ultra portable devices that we carry around in our pockets and purses and are so much a constant part of our daily lives.
The concept of the telephone dates back to the acoustic (non-electrical) string telephone or “lover’s telephone” that has been known for centuries, comprising two diaphragms connected by a taut string or wire. Sound waves are carried as mechanical vibrations along the string or wire from one diaphragm to the other. The classic example is the tin can telephone, a children’s toy made by connecting the two ends of a string to the bottoms of two metal cans, paper cups or similar items. The essential idea of this toy was that a diaphragm can collect voice sounds from the air, as in the ear, and a string or wire can transmit such collected voice sounds for reproduction at a distance.
