Samsung patents AI method to stop speakers from distorting sound
This filing describes a method for electronic devices to analyze incoming audio signals and identify specific parts that cause speaker distortion. It uses AI models trained on synthetic data to replace those distorted sections with cleaner audio before playback.
In the filing’s own words
A method for membrane excursion control of an electronic apparatus includes receiving an audio signal input from at least one audio source, extracting at least one audio parameter derived from the audio signal input, inputting the at least one audio parameter into a distortion classifier to identify a first set of audio frames in the audio signal input causing audible distortion, and generating a first output, including a second set of distortionless audio frames, by inputting the first set of audio frames causing audio distortion into a plurality of speaker models. The at least one audio parameter includes at least one of: at least one speaker characteristic and at least one signal feature. The distortion classifier is trained using a synthetic audio dataset generated using a diffusion model with a loss function. The plurality of speaker models are artificial intelligent models trained using the synthetic audio dataset.
What exactly they claim (claim 1)
1. A method for membrane excursion control of an electronic apparatus, the method comprising: receiving an audio signal input from at least one audio source; extracting an at least one audio parameter derived from the audio signal input, wherein the at least one audio parameter comprises at least one of:at least one speaker characteristic and at least one signal feature; inputting the at least one audio parameter into a distortion classifier to identify a first set of audio frames in the audio signal input causing audible distortion, wherein the distortion classifier is trained using a synthetic audio dataset generated using a diffusion model with a loss function; and generating a first output, comprising a second set of audio frames, by inputting the first set of audio frames causing audio distortion into a plurality of speaker models, wherein the second set of audio frames are distortion less, and wherein the plurality of speaker models are artificial intelligent (AI) models trained using the synthetic audio dataset.
