Abstract RU 2729972 C1

FIELD: loudspeakers.

SUBSTANCE: proposed invention relates to loudspeaker, which contains one or more dynamic heads and at least two waveguides. One or more dynamic heads are configured to emit sound waves. Waveguides are connected to one or more dynamic heads for receiving sound waves emitted by one or more dynamic heads. Each of the at least two waveguides has a cross-sectional dimension which is less than half the wavelength of the sound waves to be transmitted, and wherein length of one of at least two waveguides is at least as much as half the wavelength of sound waves to be transmitted.

EFFECT: device makes it possible to simplify beam formation.
