FILTER FOR THREE-WAY SPEAKER SYSTEM Russian patent published in 2021 - IPC H04R3/12 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in acoustic systems of household or professional sound reproducing equipment. A filter for a three-way speaker system is proposed, which contains a low-pass LC filter, an high-pass LC filter and a medium-pass frequency filter, the outputs of which are designed to connect dynamic heads of low-frequency and high-frequency and medium range, respectively. The common terminals of the inductor and the capacitor of the LC low-pass filter are connected to the output of the capacitor and the output of the inductor of the LC high-pass filter, and the second output of the inductor of the LC high-pass filter is connected to the output of the capacitor of the medium-pass frequency filter. The second terminal of the capacitor of the mid-pass frequency filter is connected to the second terminal of the inductor of the LC low-pass filter.

EFFECT: increase in the linearity of the phase-frequency characteristic of the filter while maintaining the uniformity of its amplitude-frequency characteristic.
