A traditional HiFi speaker covers a wide listening area so that many people can enjoy the same sound quality, regardless of their position in the room.
Conversely, a directional loudspeaker focuses the sound in a privileged virtual cone in which only a small group of listeners is immersed, and outside which the sound is no longer audible.
Directional speakers are used in museums, restaurants, above interactive kiosks, or above stands in tradeshows, for example, to broadcast a TV soundtrack without disturbing the neighborhood.
In practice, laws of wave physics makes extremely difficult the association between high focusing and high sound quality. That's why most of existing directional speakers just can't creat a real musical bubble, but are limited to speech signals or specific sound effects, without bass.
Originally designed for the Montreux Jazz Festival, the directional loudspeaker Opera reconciles sound quality and directivity. Thus, the Opera is the first directional loudspeaker guaranteeing an immersion both localized and musically rish. The innovation is based on a patented signal processing algorithm developed at EPFL by the Hidacs co-founders.
