Directional Speakers - Directional sound

The Acouspade™ is a hyper-directional loudspeaker that produces a precisely focussed sound beam. It can be used to place a specific sound at a specific point in the room while at the same time creating silence in other areas, known as directional sound reinforcement. Thanks to the Acouspade directional system, different sounds can be heard clearly separated from each other even in confined spaces - without distracting overlaps.

The laser-sharp focussing of the sound is based on the parametric array effect. The loudspeaker creates an audio spotlight phenomenon that transforms selected objects into virtual sound sources: They reflect the sound beam and make the sound audible locally without spreading it throughout the room.

The Acouspade directional loudspeaker revolutionises targeted audio reproduction and creates a wide range of possible applications:

With this innovative technology, several independent audio zones can be realised in one room - perfect for museums or galleries, where different exhibits can tell their story simultaneously without interfering with each other acoustically.

As an audio source for interactive kiosks and terminals, the Acouspade offers discreet and clear speech reproduction. In theme parks, it brings talking animals, characters and objects to life and creates magical moments for visitors.

For amusement parks, the directional speaker enables precise sound effects on rides that can be heard exactly where they belong. In addition, you can add ambient and background sounds to your environment - be it the chirping of birds, the sound of the sea or realistic machine noises.

Spotlight Mode

When wall-mounted above or below a digital display, the Acouspade directional speaker must be angled diagonally (downwards or upwards) to accommodate users of different heights. In this configuration, the optimal listening position varies slightly (1-2m from the screen) depending on the user's height. While this ensures the audio remains aligned with the display area, it may produce more audible artifacts in the room due to sound reflections from floors/ceilings at specific angles.

Sound Shower Mode (Optimal Configuration)

For precision audio targeting, ceiling mounting facing downward creates a defined "sound shower" effect. This configuration:

Delivers consistent audio regardless of user height

Creates a single, well-defined listening zone

Minimizes unwanted room reflections

The sound reflects between floor and ceiling, reinforcing the primary listening spot while reducing spill to other areas.

Virtual Speaker Mode (Stealth Audio)

This innovative approach directs the sound beam at reflective surfaces (like digital displays) rather than users. Key benefits:

Creates the illusion that sound originates from the target object

Completely hides the actual speaker location

Effectively draws attention to specific objects or displays

The reflected sound maintains directionality while appearing to emanate from the surface it hits.
