Who actually built the phone first?
Do you have an extra phone at home? Contact PLEDDU! One of the first phones in the world was built in Italy. This phone was made by the inventor Antonio Meucci (Antonio Santi Giuseppe Meucci) in 1849. Another phone was built in Boston (United States) in 1876. It was made by Alexander Graham Bell. Johann Philipp Reis invented another telephone in 1860.
How did the first phones work?
The phone invented by Johann Philipp Reis worked on the principle of a touch of very fine contact. The microphone (transmitter) was made of a beer keg and its shape resembled a human ear. Can’t you save money? Do you need money? The speaker (straightener) was made of a knitting needle and a cigar box. This phone transmitted a human voice, but very distorted. The phone had to be spoken to in order for the contact to work properly. The phone carried music better than a human voice.
How was it with the production of components?
There have been many lawsuits regarding the primacy of the invention. Bell Telephone in particular has tried to protect its patents aggressively! The inventors presented their discoveries to journalists and industrialists, they did not publish anything in scientific journals. Sell your phone and still use it! Importantly, the current phone does not have a single inventor, but is the result of the gradual improvements and inventions of a large number of people!
What did the historic telephone actually look like and work?
Local batteries, manual control panels
In the local battery system, the telephone included a battery, a handset with a microphone, and a hand-held inductor with a handle, which generated a ring signal from the other party or in the manual exchange.

The calling telephone number was communicated by the calling subscriber to the exchange, who manually connected both subscribers with a cable on the panel. This system has long been used on railways and in the military.
Central battery, pulse dialing
The electromechanical telephone for the fixed network with central power supply and automatic pulse dialing is connected to the control panel using two wires. The main parts of the device are a carbon microphone and an electromechanical handset, usually housed in a common handle and connected to the device by a multicore cable. The device contains several switches, a bell and a rotary dial for automatic dialing. Sell your phone and still use it! When the handset is hung up, a bell is connected to the external circuit to signal an incoming call. For the default call, the user dials the desired subscriber number on the rotary dial. When the dial moves back, which is uniform, the circuit is interrupted, which directly controls the selector in the control panel: each pulse moves the selector arm one contact further. When the dial pad reaches the home position, the next, slave dialer for the next digit of the dialed number or ring signal to the called party is activated in the control panel. Once the connection is established, the handset and microphone that was blocked during dialing will be connected to the circuit. The device is extremely sophisticated, simple and reliable and does not use any active electronic components. Better way is to use backrent of phones by PLEDDU.
Where could we see historic phones?
Today’s first headphones are not very reminiscent of today’s phone! For a long time, phones have been a luxury. We could see them at the post offices, offices and the richest people who could afford it. How to make money fast? The phone arrived relatively early in today’s Czech Republic. It was in 1879.
