How does a tin can phone work?
The highly similar acoustic tin can telephone, or 'lover's phone', has also been known for centuries. It connects two diaphragms with a taut string or wire, which transmits sound by mechanical vibrations from one to the other along the wire (and not by a modulated electric current ).
What happens when a string is pulled taut?
When the string is pulled taut and someone speaks into one of the cans, its bottom acts as a diaphragm, converting the sound waves into longitudinal mechanical vibrations which vary the tension of the string. These variations in tension set up longitudinal waves in the string which travel to the second can, causing its bottom to vibrate in a similar manner as the first can, thus recreating the sound, which is heard by the second person.
What was the first device used to teach children about sound vibration?
In the centuries before tin cans and paper cups became commonplace, other cups were used and the devices were sometimes called "lovers' telephones ". During the 20th century, they came into common use in preschools and elementary schools to teach children about sound vibration.

An example of one such company was Lemuel Mellett’s 'Pulsion Telephone Supply Company' of Massachusetts, which designed its version in 1888 and deployed it on railroad rights-of-way, purportedly with a range of 3 miles (4.8 km).
