FILTER FOR 3-WAY SPEAKER SYSTEM Russian patent published in 2021 - IPC H04R3/12 

FIELD: acoustics.

SUBSTANCE: filter for a three-way speaker system contains an LC low-pass filter, an LC high-pass filter and a mid-frequency filter, the outputs of which are designed to connect the dynamic heads, respectively, of the low-frequency, high-frequency, and mid-frequency ranges. The common terminal of the inductor and the capacitor of the LC low-pass filter is connected to the terminal of the dynamic head of the low-frequency range and the common terminal of the inductor and the first capacitor of the LC-high-pass filter, the second terminal of the first capacitor of the LC-high-pass filter is connected to the terminal of the dynamic head of the high-frequency range, and the second terminal of the inductor of the LC high-pass filter is connected to the terminal of the second capacitor of the LC high-pass filter, the terminal of the dynamic head of the mid-range and the terminal of the capacitor of the mid-frequency filter. The second terminal of the second capacitor of the LC-high-pass filter is connected to the second terminal of the dynamic head of the high-frequency range, the second terminal of the capacitor of the frequency filter of the mid-frequencies is connected to the second terminal of the inductor of the LC-low-pass filter and the second terminal of the dynamic head of the mid-range, and the second terminal of the capacitor LC- the low-pass filter is connected to the second output of the dynamic head of the low-frequency range.

EFFECT: increasing the linearity of the phase response of the filter, improving the sound quality.
