SOUND OUTPUT DEVICE HORN Russian patent published in 2021 - IPC H04R1/30 

Abstract RU 2751431 C1

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, in particular to horns. The horn of a sound output device with a radiator in the form of a dynamic head consists of several independent channels, which have a polygon cross-section, and they are twisted around their axis by the same number of revolutions, while the difference in the lengths of different channels along the longitudinal axis leaves no more than 1/4 of the wavelength itself high emitted frequency of the dynamic head, and each channel, in cross-section, has a size not exceeding the wavelength of the highest frequency of the emitted audio frequency range.

EFFECT: harmonic distortion reduction.
