The Amina® loudspeaker is unlike any conventional loudspeaker. Although it uses the term `loudspeaker`, it is far more correct to refer to it as a Distributed Mode Loudspeaker, or DML Panel.
The technology is based on the principle workings of soundboards within natural musical instruments, such as the acoustic guitar, violin or piano. Energy from the strings is transferred via a bridge to create small but powerful vibrations in the soundboard or body of the instrument itself. The vibration of the instruments mass produces excitation of the air around it, and so the Amina DML panel emulates the way sound has been produced naturally, since the beginning of time.
In Amina® DML Invisible Loudspeakers, a tiny vibration created by a specially designed electronic ‘exciter’ (effectively an electronic tuning fork) sets in motion thousands of tiny vibrations all-over a thin lightweight but rugged aluminium honeycomb composite panel soundboard. It is through this multiplication process that the initial acoustic sound generated by the exciter is acoustically amplified. The sound-board in turn excites the adjacent air molecules, causing sound vibrations to enter the room in an almost non-directional manner. Hence, a DML panel is perceived to always be facing the listener, regardless of location.
