Battery and antenna
The battery and antenna are the two parts of your cell phone that are most likely to come across (and damaged) when you open your cell phone. The battery provides the power that keeps the phone running. Nothing happens without the battery.

When you take it out, it’s surprisingly fragile and easy to drop. The antenna is the portal through which the phone is connected to other phones. On most cell phones, it’s a coil of wire attached to a removable cover that is easy to break.


Microphone and speaker
The microphone and speaker are the channels the phone uses to deliver messages from other customers to you. The microphone you speak into converts the sound into electricity. The speaker you hear converts electricity into sound.

When you talk into the microphone, your voice turns into electrical signals that are digitized and transmitted through the antenna. When another phone’s signal falls on your antenna, it is not digitized first and then sent to the speaker, where it is converted to sound.


Keyboard and LCD screen
The keypad and LCD form another pair of channels that you use to communicate non-verbally with the phone. You can send data and commands to the phone by pressing the keys on the keypad – The LCD is the way the phone transmits non-verbal information to you, including the number dialed, the last number you called, and so on. The keypad and LCD screen are capable of non-verbal communication and Commands, errors, and status handle reports.


Circuit board
The circuit board is the component of the phone that is most remote from direct interaction with you or the outside world. It’s also the phone part that controls how everything else works. It converts digital signals into analog and analog signals into digital signals.

It also contains several components that don’t fit into the other categories. These include the buzzer and vibrator to alert you of incoming calls, a SIM card to notify the cell tower of your carrier, and a monitor to check the battery level so the phone can let you know the battery needs to be charged become.
