Content: you connect two tin cans (or “diaphragms”) using a taut string or wire. The mechanical vibrations from your voice travel down the wire before being converted back into sound energy at the other end of the line. British physicist Robert Hooke was credited as the first person to invent one of these devices. Between 1664 and 1685, Hooke conducted numerous experiments with these devices. The first telephone-like device, an acoustic string phone, is credited to him in 1667. 1700s: Scientist Theorizes You Can Transmit Messages Through Electricity
In 1753, one Scottish scientist named Charles Morrison proposed an important theory: you could transmit messages through electricity by using different wires for each letter. Morrison is credited as the first person to theorize that an electric telegraph could exist. Before We Had Electrical Telephones, We First Needed Electrical Telegraphs
Mechanical devices faced some obvious restrictions.
