EXCITEMENT OF MULTICHANNEL LOUDSPEAKERS Russian patent published in 2015 - IPC H04R3/00 

Abstract RU 2545383 C2

FIELD: electricity.

SUBSTANCE: excitement system contains a splitter (107) which generates a low frequency signal and a high frequency signal from an input signal. The first exciting circuit (111, 115) is connected with the splitter (107) and generates an exciting signal for the audio exciter (105) from the low frequency signal. The second exciting circuit (117, 119) is connected with the splitter (107) and generates the exciting signal for the second audio exciter (101) from the high frequency signal. The second exciting circuit (117, 119) provides expansion of frequencies of basses for the second audio exciter (101) by means of application of low frequency boost to the low frequency signal. The processor (125) determines the indication of exciter deviation for the second audio exciter (101), and the controller (127) performs the combined tuning of transitional frequency for high and low frequency signals and the characteristics of low frequency boost on the basis of the indication of the exciter deviation.

EFFECT: invention can provide improved interaction between, for example, subwoofer and satellite loudspeakers.
