The Evolution of Phones and Their Impact on Our Lives By: Matthew Webb
Phones have changed in many ways. First of all, when first invented in march of 1876, all they were was a wooden block connected to a receiver. Now, they are way more advanced, and can do many more things. Also, when first invented, phones could not make long distance calls.
The only way to communicate long distance back then was by mail. When people would want to speak to each other by letter long distance wise, it would take weeks or even months for the people to receive the letter, and even longer to get them back.
5 Fun facts:
- The origin of the phrase ‘to put someone on hold’ was Alexander Graham Bell handing over his telephone instrument to his partner Mr Watson and saying, “here, hold this”.
- A ton of mobile phones contains more gold than a ton of ore from a gold mine.
- In the early days, telephone wires were ranked according to how tasty they were to mice and rats.
- The 555 prefix is reserved for fictional US telephone numbers.
- As a tribute to Alexander Graham Bell when he died in 1922, all the telephones stopped ringing for one full minute (14 million telephones in US and Canada were affected)
The first phone would transmit noises through a wire and you would be able to hear them from the other side.
In the 1870s, two inventors, Elisha Gray and Alexander Graham Bell, both independently designed devices that could transmit speech electrically (the telephone).
Bell patented his telephone first.
Bell found work as a teacher at the Pemberton Avenue School for the Deaf.
He later married one of his students, Mabel Hubbard.
In this first telephone, sound waves caused an electric current to vary in intensity and frequency, causing a thin, soft iron plate–called the diaphragm–to vibrate.
When that diaphragm vibrated, the original sound would be replicated in the ear of the receiving instrument.
The finger wheel of the dial interrupts the current in the phone line, creating pulses that correspond to the digits of the number being called.
The first three digits of a typical number identify the area being called; the next three, called the prefix, locate the closest central or switching office; and the last four digits represent the line number
