Problems solved by technology

[0002] Acoustic products with sound playback function (such as speakers, earphones, virtual reality equipment, etc.) usually produce large nonlinear distortion when playing sound through the speaker with a large power during use
This kind of nonlinear distortion is usually the second or third harmonic distortion, which will greatly affect the sound quality of the speaker's playback sound, and even cause damage to the speaker

Abstract

The invention discloses a sound signal processing method and device and equipment. The sound signal processing method comprises the steps that in the last signal processing cycle, an emitted signal spectrum of a target sound signal emitted by a loudspeaker and a received signal spectrum of the target sound signal received by a microphone are obtained; according to the emitted signal spectrum and the received signal spectrum, whether a distorted signal distortion frequency band appears in the target sound signal or not is detected; and when the signal distortion frequency band is detected, in the current signal processing cycle, the target sound signal is compressed according to the signal distortion frequency band, and the compressed target sound signal is emitted by the loudspeaker.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and more specifically, to a sound signal processing method, device and equipment. Background technique [0002] Acoustic products with sound playback function (such as speakers, earphones, virtual reality equipment, etc.) usually produce large non-linear distortion when they play sound through speakers with relatively large power during use. This kind of nonlinear distortion is usually the second or third harmonic distortion, which will greatly affect the sound quality of the sound played by the speaker, and even cause damage to the speaker. Contents of the invention [0003] An object of the present invention is to provide a new technical solution for sound signal processing. [0004] According to a first aspect of the present invention, a sound signal processing method is provided, including: [0005] Acquiring the transmitted signal spectrum of the target sound signal emi...
