Touch-screen platform: A special
chip is placed inside of the
platform which figures out the
coordinates on where you
touched the screen.
Speaker: A quick current of fluctuating electricity is
pumped into an electromagnet which is then pushed
through a coil and comes out in sound-waves through
a cone.
Calculator: An encoder processes a
number-when pressed- and then shows
that number or symbol onto the the
small screen. There is a small device
inside the calculator which is called a
transistor. this makes a certain formula
come out as an answer(eg 4*5=20).
Printer:
wirelessly
connected
to a PC or
more PCs
Computer Screen: Huge pixel waves surf
through a 'Cathode Ray Tube' (CRT) which is
then neatly positioned on billions of small
LCD caps.
Headphones/earphones:
Stereo wires transport the
required sounds to both
speakers (the ear buds)
from the computer,
phone and TV.
Projector: A very bright light
shines into a big LCD cap
which comes out as an
enlarged image or video
TV: Millions of tiny bright dots,which
are called pixels, are fused together
through millions of small hexagonal
lenses which then make a full image.
