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

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics and can be used in acoustic systems. The filter for a three-way acoustic 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 output of the inductor and the capacitor of the LC low-pass filter frequencies is connected to the output of the inductor of the LC high-pass filter and the output 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 LC high-pass filter capacitor, the terminal of the dynamic head of the mid-frequency range and the terminal of the capacitor of the frequency filter of the mid-frequency range, while the second terminal of the capacitor of the LC high-pass filter is connected to the second terminal of the dynamic head of the high-pass range, and the second terminal of the capacitor of the frequency filter of the middle 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-frequency range.

EFFECT: ensuring the linearity of the phase-frequency response of the filter while maintaining the uniformity of its amplitude-frequency response.
