Abstract (en)
[origin: CN111010651A] The invention relates to a loudspeaker control device and associated sound broadcasting equipment. The device (22) for controlling the loudspeakers in the sound box includes: a unit (36) for copying the desired dynamic signal (Sdyn) to obtain two identical desired dynamic signals (Sdyn1, Sdyn2); a first processing unit (38) configured to process a first desired dynamic signal (Sdyn1) to obtain a first processed signal (Sdyn1 ') whose frequency is less than or equal to a predetermined frequency; a second processing unit (40) configured to process a second desired dynamic signal (Sdyn2) to obtain a second processed signal (Sdyn2 ') whose frequency is strictly greater than the predetermined frequency; and a unit (42) for combining the first and second processed signals (Sdyn1 ', Sdyn2') to obtain the loudspeaker control signal (Scommande).
