Abstract

A compression driver for an omnidirectional loudspeaker comprises a magnet assembly disposed about a central axis, an annular diaphragm disposed coaxially above and operably connected to the magnet assembly, a phasing plug including a base portion having a first side and an opposed second side facing the diaphragm, the base portion including a plurality of apertures that extend therethrough and are arranged generally circumferentially about the central axis, the phasing plug including a raised portion extending upwardly from the base portion and defining a plurality of radially-expanding channels acoustically connected to the apertures, and a compression chamber defined between the diaphragm and the phasing plug, wherein actuation of the diaphragm by the magnet assembly generates sound waves within the compression chamber which travel through the plurality of apertures and the radially-expanding channels to create a generally horizontal 360° radiation pattern of the sound waves from the compression driver.
