A traditional landline telephone system only contains three simple parts: a hook switch, which connects and disconnects the phone from the network; a speaker; and a microphone, through which sound waves from your voice compress and decompress the granules, changing the resistance and modulating the current flowing.

A landline is a telephone that transmits signals converted from audio data through physical media, such as wire or fibre optic cable, rather than through wireless transmission as is the case with mobile phones. ... The phone base and the receiver (or handset) are connected by a cord. A variety of raw materials are used for making telephones. Materials range from glass, ceramics, paper, metals, rubber and plastics. The primary components on the circuit board are made from silicon. The outer housing of the phone is typically made of a strong, high-impact resistant polymer.
