The document discusses the key components of a cell phone and how they enable communication. It describes how the microphone converts sound signals to electrical signals, and the speaker converts electrical signals back to sound. It also mentions the display, keypad buttons, battery, and camera as important parts of a mobile phone. Faults can occur if components like the microphone or battery are damaged.

Enables To Communicate The cell phone was invented by Dr. Martin Cooper.

A Mic is also called microphone and mouthpiece . Converts to Sound signal electrical signal FAULT - If the mic get damaged ,our voice will not be heard by the other person during the Call .
N6600
Converts to electrical signal Sound signal We hear the voice of the other person during a call from the speaker
N6600
Display is of 2 types : Color Display Black and white display Color Display Black and white

It is just like a normal on-off switch . When we press The buttons of the keypad , the two connectors contact With each other . The carbon in between makes this Possible . When we press the button the carbon shorts its point and create signal .
N6600
It is of two types 1.Loose 2.Solder FAULT – Mobile phone will become dead. Mobile phone will switch off automatically. Battery discharge problem.
N6600
It supplies voltage from the charger to the battery. It is of two type 1.Loose 2.Solder

There are many types of batteries used in mobile phone but now a days the most popular batteries are “lithium Ion battery ” and “Lithium Ploymer battery”. There are two types of batteries according to their terminals. In Sony Ericson mobile phone there are five pins used For battrey terminal but don’t be confuse . First two pins Are +ve third works as BSI and the last 2 bins are -VE
+ - + -B TEMP BSI BSI Positive pin(+) Positive pin of battery gives output voltage which is normally 3.6 V or 3.7V. + - Negative pin(-) Negative pin is battery is same as in other batteries. + - BSI pin BSI stands for Battery State Indicator . This is a pin which tells the mobile phone cpu the state of battery + - (tempereature).
Do we ever think how the camera of a mobile phone work ?? Camera used in cell phone is a digital camera. Unlike analog or classic cameras, there are no film In digital camera. Instead of film, there are lots of chips. They can be CCD(Chare-Couple Device), CMOS(Complementary Metal Oxide Semiconductor) etc. There is also digital sensors with pixels laid on them. The quality of the picture totally dependent on the mega pixels.
When light from an object fall on these pixels through the camera lens, they become excited with an imprint on it. This imprinted picture is passed through a color filter which create the analog electric signals from light signals. Then the analog signal is converted to digital signal with a analog to digital signal converter. Then these signals are saved in memory chips. And the combined signals make the picture we want.
