Answer:
Between 1875 and 1915, the growth of telephone communication was due to a social need for intercommunication, which forced the first telephone in the world to be formed in 1876, by Antonius Meucci and Bell in the United States.
Then in 1861 a second prototype phone was formed which was created by Elisha Gray.
This began to trigger a large transfer of information, at the beginning few telephones were used, proposing specific communications at specific times.
In the use of the telephone, a large number of women who had access during the warlike stages were the ones who re-found their husbands, or even placed relatives in desperate situations.
As regards the telephone device itself, several things can be pointed out.
In 1915 Clark Thompson invented the candlestick phone. Candelabra phones had a mouthpiece (transmitter) mounted on top of the stand and a receiver (earpiece) that the user held in their ear while making a call. When the phone was not in use, the receiver was placed on the hook of the switch that protruded to the side of the bracket, thus disconnecting the audio circuit from the telephone network.
The introduction of the carbon microphone, which considerably increased the power emitted, and therefore the maximum range of communication.
The Luink anti-local device, to avoid hearing disturbance caused by ambient noise in the room where the phone is installed.
Pulse marking by means of the so-called marking disk.
Touchtone dialing.
The introduction of the electret microphone or electret, condenser microphone, practically used in all modern devices, which considerably improves the quality of sound.
Explanation:
