LOUDSPEAKER Russian patent published in 2017 - IPC H04R19/02 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics. Loudspeaker has three first emitting heads made with the possibility of radiating in the first frequency range and at least one second emitting head made with the possibility of radiating in the second frequency range. Herewith the first emitting heads have conical diffusers and are located in close proximity to each other at vertices of a virtual regular polygon with a number of angles equal to the number of the first emitting heads, and the second emitting head is located near the geometric center of the said virtual polygon. Conical diffusers are oriented with their convex sides in the direction of the listener, herewith the first emitting heads axes of radiation are inclined at angle (α) to the perpendicular drawn through the center of the said polygon, where the value of angle (α) ranges from 5 to 25 degrees.

EFFECT: reducing phase distortions.
