Loudspeaker or similar sound generator for any acoustic frequency ranges with damping in a cavity provided for this purpose

摘要

A damped sound generator is described, particularly a damped loudspeaker, the damping of which is predetermined directionally by a multiplicity of air columns which are largely not acoustically coupled to one another. The air columns, which are preferably combined in any side-by-side and stacked arrangement to form a package or the like are parallel to one another and their longitudinal axes, in turn, are parallel to the main direction of the axis of sound radiation. <IMAGE>
