LOUDSPEAKER APPARATUS FOR RADIATING ACOUSTIC WAVES IN A HEMISPHERE

摘要

Loudspeaker apparatus comprise commonly some sort of casings or assemblies, in which one or more single speakers are integrated and which are used to convert electrical signals into sound. A loudspeaker apparatus 1 for radiating sound in a hemisphere is disclosed having a centre axis 9, the loudspeaker apparatus 1 comprising: a set of midrange drivers 6 a, b, c, d, e, f, whereby the midrange drivers 6 a, b, c, d, e, f are controlled and/or arranged in a Bessel configuration and are operable to provide a first acoustic field in the hemisphere, a set of tweeter drivers 7 a, b, c, d adapted to provide a second acoustic field in the hemisphere, whereby the first and the second acoustic field are respectively arranged symmetrically around the centre axis 9 of the hemisphere, whereby the main sound emitting directions of the single tweeter drivers 7 a,b, c, d are angled to the centre axis 9.
