Abstract

A device (1) for the diffusion of sound comprising a supporting structure (2) associable with a source unit (3) of the sound, diffusion means (4) of the sound associated with the supporting structure (2), connection means between the source unit (3) and the diffusion means (4), where the diffusion means (4) comprise a discharge collector (5) defining at least a hollow channel (6) having at least an opening (7), facing outwards and adapted to house at least a loudspeaker (13), and at least a further opening (9) which is free for the output of the sound generated by the loudspeaker, and where at least a portion of the hollow channel (6) has a silica-based surface coating (11) adapted to facilitate the sliding of the sound waves.
