Introduction

    Headphones convert electric signals into sounds.
   
Earbud Parts
     The wires transmit a current to the coil.  That coil is attached to the transparent plastic cone also known as the diaphragm.  The coil is then placed inside part of the magnet.  Now the electric current will determine how the coil is affected by the magnet.  The coil will be pulled and pushed by magnetism.  This vibrates the diaphragm which then makes the air vibrate creating the specific vibrations in the air.  The vibrations are then received by your ear drum.
