The parts of a cell phone
If you take a basic digital cell phone apart, you find that it contains just a few individual parts:
An amazing circuit board containing the brains of the phone
An antenna
A liquid crystal display (LCD)
A keyboard (not unlike the one you find in a TV remote control)
A microphone
A speaker
A battery
