摘要

The loudspeaker with circumferential sound radiation comprises at least one sound generator (1, 2) whose membrane (3, 13) is oriented vertically upwards, and a conical diffuser (15) whose longitudinal axis (17) coincides with the area normal (18) of the membrane. The diffuser with a concave side surface (23) has a tip (16) which points to the center of the membrane.
