Transcript of MOBILE
The antenna is made from Magnesium.
The condenser is made from Cotlan.
The sheets are made from fiberglass.
The chips are made from Silicon. Also there are made from precious metals: gold, silver, platinum, palladium and copper.
The displays are generally LCD (Liquid Crystal Display)
LC (Liquid Crystal): liquid crystals are matter in a state that has properties between those of conventional liquid and those of solid crystal.
There are many different types of liquid-crystal phases, which can be distinguished by their different optical properties
Normally the display is protected by a sheet of toughened alkali-aluminosilicate glass which is resistant to scratching, impact and torsion.
A lot of mobile phones batteries are made from Lithium-Ion (sometimes Li-Ion battery or LIB).
It's rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.
The external cover is made of polymers or aluminium.
There are different polymers used but generally they're cheap, ductile and resitant to impacts.
Aluminium is cheap, lighter and resistant.
On a mobile phone there are
An under microphone which
record a lot of sound. And back
a microphone that eliminate
The are two speakers:
Lens: made of special optical glass.
The speakers are made from quartz or ceramic
Filter: made of blue glass
VCM: magnets and a copper coil
In the future batteries will be make from micro cellular methanol.
Each piece of the cell phone is created separately.
First, the casing for the phone is made. Most cell phones use a simple plastic or aluminium that is created using a process known as injection molding.
After the phone is moved on to testing.
During the testing phase, the battery for the phone is added and a worker checks the phone for power, button functionality and reception.
Finally, the necessary documentation for the phone is produced and sent to be packaged with the phone.
Secondly the printed circuit board is made and loaded with the necessary software/operating system. The circuit board is then placed in the casing, using a series of eyeglass screws.
Next, the other components of the phone are added: display, camera, antenna, microphone and speaker.
