The telephone is a very simple device because the telephone connection that we have in our houses has not changed in almost a century. So, it does not matter if you have a telephone from the 1900s that if you connect it, it will work. The telephone has only 3 parts, the switch (hook switch), the speaker, and the microphone. The switch is used to connect or disconnect the phone from the network. The speaker is used so that the person that is using it can hear. The microphone is used so that the two persons that are calling can communicate. The microphones are so simple that they are carbon granules between two metal plates. Most modern telephones have a bell, a touch pad keypad and a frequency generator. Also, the microphone instead of being carbon granules is an electronic amplifier. The telephone has changed and evolve throughout the years from simple ones to more sophisticated ones. The first telephone was created based on the telegraph. The telegraph had been used for a long time to communicate, but the problem was that it could only receive or send one message at a time, and it used Morse code.

  • How the Telephone Changed History

    On March 10th, 1876, a revolutionary invention was created by Alexander Graham Bell. The telephone was invented to send vibrations from one receiver to another electrically (History.com ‘Speech Transmitted by Telephone’ accessed on March 11, 2014), and due to Alexander Graham Bell accidentally discovering that he could hear the sound of a ‘clock spring twanging’ (Marry Bellis, ‘The History of the Telephone’ accessed on March 11, 2014), that was possible. The invention of the telephone permitted new levels of communication, allowed families connect around the world, and improved military systems, but also served negative consequences, such as breached privacy. If two people wanted to have a conversation, they would have to write letters back and forth, but with the telephone they were able to pick up the receiver, dial the number, and be connected in a matter of minutes. Telephones enabled long-distance communication, which allowed families to converse despite their location. Military officials and soldiers were also able to stay in touch through field telephones as well as keep contact with the president. Although telephones were originally placed in general stores or other major city locations and homes/neighborhoods that were wired (Elon.edu ‘World Changes Due to the Telephone’ accessed on April 2, 2014), telephones became commonly used in homes in the early twentieth century when telephones began to connect internationally.

The hydraulic semaphores, which functioned with water filled containers and visual signals, functioned as optical telegraphs. However, they could only apply a very limited range of pre-determined messages, and as with all such visual telegraphs could only be deployed during good visibility conditions. Experiments on communication using electricity was carried out in 1729 but was not successful. The experiment was proposed by William Fothergill Cooke. In 1837, William invented a practical electric telegraph which entered commercial use in 1838 (J. B. Calvert, May 2004). The first telephone was invented in 1878 by Alexander Graham Bell. He experimented with a ‘phonautograph’, it is a machine shaped like a pen that can draw shapes of sound waves on smoked glass by tracing vibrations.
