The present invention relates to a spatial arrangement for optimizing the broadcasting of a sound signal and thus replacing the conventional stereo systems. For this purpose, the spatial arrangement is capable of broadcasting a spatialized sound signal, the spatialized sound signal comprising N mutually distinct audio signals, N being an integer strictly greater than 3, and the spatial arrangement comprising a set of N sound broadcasting devices predominantly distributed over the entire width of a scene. Each sound broadcasting device receives an audio signal of which it will amplify and broadcast the transmitted sound. In particular, each sound broadcasting device is specifically capable of reproducing and preserving the characteristics of the sound transmitted by the audio signal received, in particular the sound frequency bands and the sound intensity of the frequency bands of the audio signal.

Spatial arrangement of sound broadcasting devices

The present invention relates to a sound diffusion device () comprising a single box () and, in this single box (), at least two superimposed high-frequency acoustic sources (), and a plurality of superimposed medium and/or low-frequency sources () and arranged to the left and/or to the right of the high-frequency acoustic sources (), the high-frequency acoustic sources () being coupled individually to a wave guide () so as to generate a vertical wave front with a fixed non-constant curvature. Such a device () makes it possible to minimise discontinuities between the acoustic sources providing high quality sound diffusion (no parasite lobe), to considerably reduce the weight and the cost of manufacturing and also enables rapid installation which does not require the angular adjustment of each acoustic source relative to one another contrary to existing devices.
