To understand how flat-panel technology works, however, it helps to know how a traditional loudspeaker works. In a traditional speaker, the combination of an electromagnet, permanent magnet and a voice coil receive electric current from your audio cables. As the polarization of the magnets fluctuates, the vibrations caused by the alternating currents that ripple across the diaphragm. The round cone shapes within a speaker are known as drivers. As the diaphragm inside the driver vibrates, it pushes sound waves out into the air and ultimately into your ear.

Flat-panel speakers use some of the same physical principles traditional speakers use, but apply them differently. A conductive diaphragm panel is sandwiched between two conductive panels. The outer conductive panels are charged by an electrical source, one carrying a positive charge, the other, negative. When the speaker's coil begins to vibrate with signals from the audio source, the diaphragm panel is pulled back and forth between the positive and negative panels, mimicking the magnetic action found in traditional speakers. This continual pulling back and forth creates the sound waves you hear.

"You can even put it against your head and play music directly into your skull (the ultimate surround sound)."
