Abstract
An omni-directional speaker system includes a deflector sub-assembly and a pair of acoustic sub-assemblies. The deflector sub-assembly includes a pair of diametrically opposed acoustic deflectors. Each of the acoustic sub-assemblies includes an acoustic driver for radiating acoustic energy toward an associated one of the acoustic deflectors. The acoustic sub-assemblies are coupled together via the deflector sub-assembly.
Claims29
An omni-directional speaker system, comprising:
- a deflector sub-assembly comprising a pair of diametrically opposed acoustic deflectors;
- and
- a pair of acoustic sub-assemblies each comprising an acoustic driver for radiating acoustic energy toward an associated one of the acoustic deflectors,
- wherein the acoustic sub-assemblies are coupled together via the deflector sub-assembly.
A method of assembling an omni-directional acoustic assembly, the method comprising:
- coupling a deflector sub-assembly comprising a pair of diametrically opposed acoustic deflectors to a first acoustic sub-assembly comprising a first acoustic enclosure and a first acoustic driver such that the first acoustic driver is arranged to radiate acoustic energy toward a first one of the acoustic deflectors;
- and
- coupling the deflector sub-assembly to a second acoustic sub-assembly comprising a second acoustic driver and a second acoustic enclosure such that the second acoustic driver is arranged to radiate acoustic energy toward a second one of the acoustic deflectors.
An acoustic deflector sub-assembly, comprising a pair of diametrically opposed omni-directional acoustic deflectors;
- a first pair of vertical legs for mounting to a first acoustic sub-assembly such that a first one of the acoustic deflectors is arranged to deflect acoustic energy radiated from the first acoustic sub-assembly;
- and
- a second pair of vertical legs for mounting to a second acoustic sub-assembly such that a second one of the acoustic deflectors is arranged to deflect acoustic energy radiated from the second acoustic sub-assembly.
An acoustic deflector sub-assembly, comprising
- a pair of diametrically opposed omni-directional acoustic deflectors;
- wherein each of the omni-directional acoustic deflectors comprises an acoustically reflective body having a truncated conical shape including a substantially conical outer surface, a top surface and a cone axis, each acoustically reflective body having an opening in the top surface centered on the cone axis, and
- wherein the acoustically reflective bodies together define a shared acoustic chamber that is acoustically coupled to the openings in the top surfaces of the acoustically reflective bodies.
