Abstract:
1. Spherical sound source, comprising: a. two substantially identical enclosures, said enclosures symmetric with respect to a common horizontal, lying between them, plane of symmetry, and with respect to a common vertical axis of symmetry, said axis perpendicular to said plane of symmetry, whereby each enclosure sidewall is generated as a surface of revolution around said vertical axis of symmetry with predetermined curvature of said surface and has two axial openings on both sides for loudspeaker mounting; b. two coaxial loudspeakers, mounted in both opposite substantially circular openings of said enclosures, said coaxial loudspeakers closing with their low-frequency membranes enclosure volume as means of making up low frequency close box arrangement of each enclosure, and radiating axially high frequencies by their high-frequency compression drivers; c. two mid-high frequency compression drivers, mounted at both other said openings of both said enclosures, so that said drivers' outputs radiate sound waves in phase each to the other into a common radially expanding horn, and said radially expanding horn is formed by said enclosure side walls.
