==SPEAKER OUTPUT CHARACTERISTIC CORRECTION SYSTEM AND SOUND SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240236565 titled 'SPEAKER OUTPUT CHARACTERISTIC CORRECTION SYSTEM AND SOUND SYSTEM

The abstract of the patent application describes a system where a controller calculates various parameters, including nonlinear parameters, of a speaker model based on the measured displacement of a speaker's vibration system. A sound generator produces an audio signal, and an output flattening filter adjusts the gains of different bands of the audio signal to flatten the frequency characteristic of the sound output by the speaker according to the speaker model. A nonlinear inverse filter then corrects the audio signal to suppress the speaker's nonlinear distortion based on the speaker model, ultimately delivering an optimized audio signal to the speaker via an amplifier.

* The system calculates individual and nonlinear parameters of a speaker model based on measured displacement.
* An output flattening filter adjusts gains of different bands of an audio signal to flatten the frequency characteristic of the sound output.
* A nonlinear inverse filter corrects the audio signal to suppress nonlinear distortion of the speaker based on the speaker model.
* The system optimizes the audio signal output to the speaker via an amplifier.
* The innovation aims to improve sound quality by minimizing nonlinear distortion in speaker output.

==Original Abstract Submitted==

a controller calculates individual parameters, including nonlinear parameters of a speaker model, based on a measured displacement of a vibration system of a speaker. a sound generator outputs an audio signal, and an output flattening filter adjusts gains of individual bands of an audio signal so that a frequency characteristic of a volume of sound output by the speaker is flattened in accordance with a speaker model obtained by linearizing calculated parameters and outputs a resultant audio signal. a nonlinear inverse filter corrects the resultant audio signal by signal processing adapted to the gains of the output flattening filter so that the nonlinear distortion of the speaker is suppressed in accordance with the speaker model including the nonlinear parameters and outputs the corrected audio signal as an output audio signal to the speaker via an amplifier.
