In General, earphones, speakers (Speaker), which serves to change the signal. Electrical signals, sounds, style, structure of headphones just like regular speakers but are designed to be small and is in the shape that is limited by the space to fit the use of headphones is a popular phone electromagnetic mouth similar to a magnetic but electrical signals make the file back to the input with coil (Voice Coil) will cause a magnetic field will come to push or attract with permanent magnetic powers in e as the Voice Coil motion occurred that caused the sound. There are thousands of coils exist at both terminals of a permanent magnet. Where the coils are serialized, but thousands returned to this same direction, permanent magnetic magnetic attraction is the power plate Diaphragm comes when there is a power switch (Current Speech). Flowing through the coil, it will in effect cause the magnetic force lines up the direction of the magnetic force lines is the direction opposite to the direction of the electric current that flows in a circuit, which may be accessory or resistance to magnetic force of magnetic line of permanent magnet. Diaphragm plate will move in and out of the size and frequency of Speech which will result in Current causes a wave that size and frequency is equal to the Current flowing into the Speech circuit, the sound waves that occur, it will inevitably be lost to some extent because of the power of sound waves, so Output is less than the energy Input of the Receiver.
