Abstract (en)
[origin: WO2018022087A1] An omni-directional acoustic deflector (112) includes an acoustically reflective body that has a truncated conical shape which includes a substantially conical outer surface that is configured to be disposed adjacent an acoustically radiating surface (e.g., a diaphragm) of an acoustic driver (102) thereby to define an acoustic radiation path therebetween. The acoustically reflective body (112) is profiled such that a cross-sectional area (T1, T2) of the acoustic radiation path increases monotonically with respect to radial distance from a motion axis of the acoustic driver.
