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.
