BASIC OF TELEPHONE
2. STRUCTURE OF A TELEPHONE
A telephone consists of a receiver (speaker), a transmitter (microphone), a
voice circuit, a dial, a bell (speaker), and a hook button.
Of these parts, the parts that play the most important roles are the transmit-
ter and the receiver. The transmitter converts human voice to electrical sig-
nals, and the receiver converts the electrical signals from the other party to
voice.
Here, let’s learn about the mechanism of these parts and the roles that they
perform.
