Wide-band diffusor, with high efficiency and high directivity

摘要

The invention concerns a wide-band sound diffuser with high efficiency and directivity, consisting in a body, a front reflecting parabolic element (13), at least one active element (11) at the centre of said reflecting element, and a horn (12) which expands from the rear and around the reflecting element with a progression starting from the active element to the emission mouth (16) facing in the same direction as the reflecting element. The reflecting element has a front emission in the direction of the mouth of the horn and a rear emission directed towards the horn.
