LIVE SOUND SPEAKER Russian patent published in 2023 - IPC H04R1/28 H04R3/00 

FIELD: acoustics.

SUBSTANCE: acoustic system consists of two similar speakers, in each sound strip of which, at a minimum distance from the main strip loudspeaker, six satellite loudspeakers of minimum power with a similar amplitude-frequency characteristic are installed, connected to each other in series and out of phase in three pairs. The first two pairs with opposite-sign ends are connected by one of them to the similar terminals of the bandpass loudspeaker, and the second ends are brought out of the column and connected to the analogous terminals of the second column through wire adjustment resistors. The third pair of satellite loudspeakers is connected through a series wire resistor in parallel to the bandpass loudspeaker. Thus, circuits are formed that connect each output of the bandpass loudspeaker to each other and to both leads of the bandpass loudspeaker of the other column through resistors and satellite speakers, providing additional two-phase stereo reproduction. In parallel with each pair of loudspeakers connected between the speakers, tuning wire resistors are connected. Adjustment resistors balance the output power of the bandpass loudspeaker and satellites, and tuning resistors ensure the naturalness of the timbre.

EFFECT: in naturalness, naturalness, as well as sound quality.
