March Further information: Electrical telegraphTimeline of the telephoneand History of the telephone The concept of the telephone dates back to the 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.

Gauss's and Weber's invention is purported to be the world's first electromagnetic telegraph. He observed that connecting and disconnecting the current caused a ringing sound in the magnet. He called this effect "galvanic music".
Charles Bourseul[ edit ] Charles Bourseul was a French telegraph engineer who proposed but did not build the first design of a "make-and-break" telephone in That is about the same time that Meucci later claimed to have created his first attempt at the telephone in Italy.
It is certain that, in a more or less distant future, a speech will be transmitted by electricity. I have made experiments in this direction; they are delicate and demand time and patience, but the approximations obtained promise a favorable result.
Allegedly, the transmitter was difficult to operate, since the relative position of the needle and the contact were critical to the device's operation.
Thus, it can be called a "telephone", since it did transmit voice sounds electrically over distance, but was hardly a commercially practical telephone in the modern sense.
Thomas Edison tested the Reis equipment and found that "single words, uttered as in reading, speaking and the like, were perceptible indistinctly, notwithstanding here also the inflections of the voice, the modulations of interrogation, wonder, command, etc. The results also confirmed it could transmit and receive speech with good quality fidelitybut relatively low intensity.
His caveat describes his invention, but does not mention a diaphragm, electromagnet, conversion of sound into electrical waves, conversion of electrical waves into sound, or other essential features of an electromagnetic telephone.
Ina description of it was reportedly published in an Italian-language New York newspaper, although no known copy of that newspaper issue or article has survived to the present day[ citation needed ]. Meucci claimed to have invented a paired electromagnetic transmitter and receiver, where the motion of a diaphragm modulated a signal in a coil by moving an electromagnet, although this was not mentioned in his U.
A further discrepancy observed was that the device described in the caveat employed only a single conduction wire, with the telephone's transmitter-receivers being insulated from a 'ground return' path.
In the s Meucci was credited with the early invention of inductive loading of telephone wires to increase long-distance signals[ citation needed ]. Unfortunately, serious burns from an accident, a lack of English, and poor business abilities resulted in Meucci's failing to develop his inventions commercially in America.
Meucci demonstrated some sort of instrument in in Havana, Cubahowever, this may have been a variant of a string telephone that used wire. Meucci has been further credited with the invention of an anti- sidetone circuit.
However, examination showed that his solution to sidetone was to maintain two separate telephone circuits and thus use twice as many transmission wires[ citation needed ]. The anti-sidetone circuit later introduced by Bell Telephone instead canceled sidetone through a feedback process.This led him to invent the microphone and later the "electrical speech machine" -- his name for the first telephone.
Bell was born in Edinburgh, Scotland on March 3, He enrolled in the University of London to study anatomy and physiology, but his college .
Perhaps even more importantly, paper currency was the vital first step in a new monetary system that led to the birth of credit cards and electronic banking.
Before the invention of telephones, mail was a large part of life. This was mainly because it was the only way of communication. Telephones are a huge part of today's life.
As telephones became more and more advanced they also became more and more popular. Now it is the most common way of communication. In the Industrial Revolution, many inventions were created that had led to significant impacts to society.
One of these inventions included the telephone. The telephone was made in by Alexander Graham Bell.
The invention of the telephone had a great impact towards society and broadened the idea of . The invention of the telephone was the culmination of work done by many individuals, and led to an array of lawsuits relating to the patent claims of several individuals and numerous companies.
The first telephone was invented by Antonio Meucci, but Alexander Graham Bell is credited with the development of the first practical telephone. The invention of the telephone offered an instantaneous form of communication that spawned other valuable communication tools, such as the Internet and cellular phones.
The telephone is important for its ability to reduce the distance users need to communicate.
