FIELD: electro-acoustics.
SUBSTANCE: acoustic system contains a loudspeaker, positioned in a volumetric body made of sound-absorbing material, frontal part of which serves as emitter of primary acoustic signal. Additionally the acoustic system contains at least one conic vortex damper in back part of the loudspeaker in form of rigid radially sector-like blades twisted along their length, smoothly changing the incidence angle to the flow of passing acoustic signal.
EFFECT: improved sound quality of acoustic system at low frequencies, reduced dimensions.
