Title:
NONLINEAR DISTORTION COMPENSATION CIRCUIT, APPARATUS AND METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/194209
Kind Code:
A1
Abstract:
The present application discloses a nonlinear distortion compensation circuit, apparatus and method, and an electronic device. The nonlinear distortion compensation circuit comprises: a first input end of a linear dynamic circuit is used for inputting an audio signal, a second input end is used for inputting a loudspeaker model parameter, and an output end is respectively connected to a first input end of a gain module and a first input end of a multiplier. A second input end of the gain module is used for inputting an audio signal, a third input end is used for inputting a loudspeaker model parameter, and an output end is connected to a second input end of the multiplier. An output end of the multiplier is connected to a first input end of a nonlinear inverse dynamic circuit. A second input end of the nonlinear inverse dynamic circuit is used for inputting a loudspeaker model parameter, and an output end is connected to a loudspeaker. Compression gain output by the gain module is used for compressing, by means of the multiplier, a linear signal output by the linear dynamic circuit.
