AudioBeam

Conference and Information Systems AudioBeam

AudioBeam

The AudioBeam directional loudspeaker works with ultra-sound, modulating the audible sound onto an ultrasonic carrier frequency, much like a radio station does, and then emitting this signal via 150 special piezoelectric pressure transducers. Audible sound is only generated at a distance from the AudioBeam, when the signal is demodulated because of the non-linearity of air. This can be imagined like the creation of many small, virtual loudspeakers in the ultrasonic zone.

No sound is audible beside or behind an AudioBeam – you will only hear the audio information if you are directly within the sound beam, or if the sound is reflected by a smooth surface. This makes AudioBeam an ideal tool for information terminals, exhibitions, or even conferences where various AudioBeams emit several languages to a defined part of the auditorium.

As the effects of ultrasound on the human body have not yet been thoroughly investigated, AudioBeam is fitted with a sensor that switches the loudspeaker off when it registers movement within four metres.

AudioBeam is suited to a wide variety of applications:

For theme parks and exhibitions

￿AudioBeam is an ideal tool for theme parks where it creates amazing effects with moving sound when combined with a small stepper motor. In an exhibition,

AudioBeam will give explanations on an exhibit, which are only audible within a defined area. When mounted opposite an exhibit, the work of art will seem to ”talk“ to the visitors, as the ultrasonic beam is reflected by smooth surfaces.

For the PC

￿PC users can forget all about headphones. AudioBeam is their personal loudspeaker – without disturbing others in the office.

Automatic machines with voice function

￿A very discreet way of addressing customers: the sound will only reach the person directly in front of the machine.

In safety areas

￿AudioBeam can be used to directly address an individual person within a safety area – putting them in an audio spotlight.
