Sennheiser Worldwide: Audiobeam - Conference - Soundstation / Loudspeakers / Audio Beam -- Equipment Manufacturer


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. AudioBeam 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. 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.
