ACOUSTIC DEFLECTOR FOR OMNI-DIRECTIONAL SPEAKER SYSTEM

摘要

An omni-directional acoustic deflector includes an acoustically reflective body having a truncated conical shape including a substantially conical outer surface, a top surface and a cone axis, the acoustically reflective body having at least one opening disposed along a circumference of the substantially conical outer surface at a cone radius associated with a pressure maximum of an acoustic resonance mode with an acoustic absorber at each such opening. Speaker systems employing the omni-directional acoustic deflector have an improved high frequency acoustic spectrum response regardless of the location of the listener with respect to the speaker system.
