Inside a Cell Phone
On a “complexity per cubic inch” scale, cell phones are some of the most intricate devices people play with on a daily basis. Modern digital cell phones can process millions of calculations per second in order to compress and decompress the voice stream.
The parts of a cell phone
If you take a 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
In the next section, we’ll look closer at the circuit board and its components.
