How Does the Telephone Operate
For those of you who are wondering how does the telephone operate, here’s the explanation in layman’s terms.
Working of Telephone
The two basic parts of a telephone are the handset and base; the handset that you speak into or listen from transmits and receives the sound. This mouth-piece is integrated with a thin metallic coating which is divided from an electrode via a thin barrier that bonds to a wire with electric current. When a person speaks, the acoustic vibrations from the voice move the metallic coating towards the electrode which results in variations in voltage. This converts the vibrations to electric energy which is then transmitted through a wire to the person at the other end where it is again converted back to acoustic energy. Thus, there is an effective communication.
The Essential Elements
Well insulated electric wires are very much necessary for a reliable communication as it prevents the sound energy from escaping out before reaching the destination. Insulated wires help in transmission of voice locally even for long distances. Acoustics work together with electricity in order to achieve this.
That was a brief and simple explanation as to how the telephone operates.
