ACOUSTIC SYSTEM Russian patent published in 2015 - IPC H04R3/12 

FIELD: physics.

SUBSTANCE: acoustic system comprises low-frequency, high-frequency and mid-frequency radiators; inputs of the system are intended for connecting an amplifier, capacitors from the first through the sixteenth, resistors from the first through the sixth and an inductor. The first lead of the low-frequency radiator is connected through parallel-connected inductor and third capacitor to the positive input of the system, and the second lead of the low-frequency radiator is connected to the negative input of the system. The low-frequency radiator is connected in parallel to series-connected first and second capacitors, series-connected fifth resistor and thirteenth capacitor, as well as the twelfth capacitor. The first lead of the high-frequency radiator is connected through the fifteenth capacitor to the positive input of the system; the second lead of the high-frequency radiator is connected to the negative input of the system; the first lead of the mid-frequency radiator is connected through the sixth resistor to the positive input of the system; the second lead of the mid-frequency radiator is connected to the negative input of the system; the mid-frequency radiator is connected in parallel to the fourteenth capacitor.

EFFECT: high sound quality.
