Abstract
Provided are a signal processing system and electric device. The signal processing system includes: an input signal module, a displacement model, a filter coefficient generation module, a group delay compensation module, an adjustable equalizer, an amplifier and an audio converter. The input signal module is connected to the group delay compensation module and the displacement model, respectively; the displacement model is connected to the filter coefficient generation module; the group delay compensation module is connected to the adjustable equalizer; the adjustable equalizer is connected to the amplifier, the amplifier is connected to the audio converter, and the filter coefficient generation module is connected to the adjustable equalizer. The driver displacement related frequency response variation is corrected over a wide frequency range and through this reduces distortion, especially intermodulation distortion.
