Ultrasonic audio technologies


Speaker with focus

The Acouspade™ is a hyper-directional speaker, emitting a highly directional beam of sound. It is able to place a particular sound at a desired spatial location, while preserving silence where the sound is not needed. The Acouspade directional sound system also allows the co-existence of different sounds in a relatively small spatial area without mixing or interfering. The lazer-like directionality of sound is achieved by exploiting the parametric array effect. The Acouspade speaker creates an audio spotlight phenomenon, which can turn selected objects into virtual sound sources, reflecting the primary beam of sound.


Touch the sound

Syntact™ is a new musical interface based on the revolutionary technology of contact-free tactile feedback. A curved array ultrasonic transducers is focusing acoustic energy into one spatial point, creating a tangible vibration in midair. Syntact™ enables musicians to virtually mold and shape the sound with their hands. The technology behind Syntact can further be used for creating futuristic Human-Computer interfaces, which can add a tactile experience to holograms.


Classic Directional speaker

Ultrasonic audio technologies was established in 2011, when it launched it first directional speaker product. Acouspade Classic uses an external mudulator and amplifier called UMA 3.0, which enables a circular, light-weight and slim emitter design. UMA3.0 usess a Class-D amplifer and a fully analog signal processing system. Acouspade Classic has been shipped to custommers worldwide and is mostly used in museums, galleries retail stores as well as in digital signage applications. Like the new Acouspade it can deliver a narrow beam of sound to a desired area, where the sound is needed, while preserving silence around it.
