The Panphonics audio element operates similarly to the electrostatic operating principle. The element consists of two protective porous panels, forming the structure of the element, together with a thin plastic film located between the panels. The film is caused to vibrate inside the panels by electric means.

The Panphonics audio element is inherently a dipole source. Both sides of the panel emit the same audio signal, with reversed phase at the rear side. This results in a momentary increase of sound pressure at one side of the panel along with an equivalent decrease of sound pressure at the other side.

Dynamic voice-coil/diaphragm loudspeakers are quite limited by finite mass and cone resonance, which break up the ideal piston motion of the cone at medium and high frequencies. In Panphonics transducers, a very light diaphragm is driven equally at all points of the surface, acting as a constant-phase piston source independent of frequency.

Panphonics Audio Element offers considerable technical advantages over conventional dynamic loudspeaker technology and flat panel speaker technology. Some of the most significant technical advantages are directivity, a nonmagnetic environment, superior sound quality, considerable reduction in mechanical vibration and an even sound field.

Unique audio features:

• Controllable directivity enables high quality sound to be played into a particular spot without disturbing the surroundings.
• Sound pressure level does not attenuate with distance in the same way as with conventional electro-dynamic speakers and thus, the technology enables an even sound field over long distances.
• Uniform frequency response and phase alignment enable high quality audio to be played with low volumes.

Unique structural features:

• The elements can be camouflaged and hidden in structures and as such be invisible.
• The exceptionally low weight and thin elements can be bent and cut.
• The elements can be used as projection surface and can be printed or painted on.
