History, main models and curiosities

It is practically impossible to imagine ourselves without a telephone in our lives, time has passed and with this it has gained more and more space in society. On March 10, the phone turned 146 years old.

The device appeared unexpectedly, by surprise, with the idea of ​​​​improving telegraph transmissions, a communication device at the time. At that time, no one imagined what would become of the telephone.

first phone

In 1876, scientist and inventor Alexander Graham Bell solved the problem of the telegraph which only allowed one message at a time. What many don’t know is that the inventor realized that it would be possible to convey more than one message through music. At this time he named it multiple telegraph, which would be the telephone of the time.

The first device worked in a very basic way, so you listened or talked, you couldn’t do both at the same time. He had a wooden box which was his battery. It arrived in Brazil a year after its creation, in 1877, and was made especially for Dom Pedro II. It was installed in the Imperial Palace of São Cristovão located in Quinta da Boa Vista, today National Museum of Rio de Janeiro, and was connected to the ministerial houses, which was the first Brazilian telephone line.

Going a little further in 1904, the second model was created. Its appearance divided opinion, it featured a mouthpiece mounted on top of the holder, as well as a receiver that the wearer held to the ear. To place the call, it was by a crank, and an operator terminated the call. This type of model required installation near a station housing the bell to announce incoming calls and the electrical circuits (capacitor, induction coil, signaling generator, connection terminals) to connect the device to the telephone network. Which was not at all comfortable and new projects for the device were already beginning.

Public telephone

Over time, phone models have evolved. At that time, the impact of globalization on people’s lives was noticeable, they spent more time on the streets than at home.

The devices were scattered throughout the cities, making it easier for people to access.

A milestone in the 90s, the famous brick is launched as the first mobile phone in Brazil, created by Motorola. But its value was not so accessible… if it was today, its value would reach R$15,000. This made landline phones more popular and it is common for lower middle class people to have one at home.
