Product Specification Telephone KX-TS820ND
Telephone KX-TS820ND is a common telecommunication tool. Aircraft in another sense also means the extension of the telephone line to be connected / diverted to a particular part of the building (English: extension, generally abbreviated as ext in Indonesia).
The phone works by sending sound waves through an electric current in the telephone network so that we can communicate with other phone users. The receiver will capture the electrical vibrations of our voice as the sounds it hears.
When we talk on the phone, we pull out sound waves from the mouth. Sound waves that are carried by the electric current to the other person. When we talk on the phone, sound waves will hit the diaphragm so the diaphragm vibrates. Behind the diaphragm is placed a small set of carbon grains that will be depressed if the diaphragm vibrates. When the carbon granules are depressed, the electrical resistance becomes smaller, causing the electric current to flow through the telephone circuit.
Simply put, the cable phone working system is as follows:
a. the sound of the sender is received by a device called a diaphragm (microphone)
b. diaphragm (microphone) converts sound waves into electrical signals and then transmitted by telephone devices
c. the signal is routed through the cable to the telecommunication center
d. from the telecommunication center, the signal is forwarded to the receiver
e. once it reaches the router, the signal is converted again into sound waves by a device called a speaker
