General Description
AudioBeam is a new type of directional loudspeaker that is able to focus sound like
the light beam of a torch, creating an audio spotlight for museums, exhibitions,
theme parks and many other applications. Unlike conventional loudspeakers, which
are only able to focus sound at high frequencies, AudioBeam emits sound as a lobe
that can be precisely directed and is reflected by objects.
