Abstract: The present invention discloses a signal processing device, a signal processing method and a speaker. The signal processing device comprises a multi-band dynamic range controller, wherein the multi-band dynamic range controller receives an audio signal and includes a first band splitting unit and a resonant band adjustment unit; the first band splitting unit is configured to split the audio signal into multiple bands and obtain at least one resonant band therefrom, which has a resonant frequency band signal in a resonant frequency range of the audio signal; and the resonant band adjustment unit is configured to adjust the resonant frequency band signal based at least on a resonant band dynamic range control gain and output an adjusted resonant frequency band signal for combination with other band signals into a compression output signal.
