NON-LINEAR DISTORTION COMPENSATION CIRCUIT, APPARATUS, METHOD, AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022215 titled 'NON-LINEAR DISTORTION COMPENSATION CIRCUIT, APPARATUS, METHOD, AND ELECTRONIC DEVICE

Simplified Explanation

The abstract describes a non-linear distortion compensation circuit that is used to improve audio signal quality. The circuit includes several components such as a linear dynamic circuit, a gain module, a multiplier, and a non-linear inverse dynamic circuit.

  • The linear dynamic circuit takes in an audio signal and outputs a linear signal.
  • The gain module and multiplier are connected to the linear dynamic circuit and are used to compress the linear signal.
  • The compressed signal is then inputted into the non-linear inverse dynamic circuit.
  • The non-linear inverse dynamic circuit takes in loudspeaker model parameters and outputs a signal that is connected to a loudspeaker.

Bullet points explaining the patent/innovation:

  • The circuit compensates for non-linear distortion in audio signals.
  • It includes a linear dynamic circuit, gain module, multiplier, and non-linear inverse dynamic circuit.
  • The gain module compresses the linear signal using a compression gain.
  • The non-linear inverse dynamic circuit uses loudspeaker model parameters to improve audio signal quality.
  • The circuit aims to provide a more accurate and high-quality audio output.

Potential applications of this technology:

  • Audio systems and equipment such as speakers, headphones, and amplifiers.
  • Professional audio recording and production studios.
  • Home entertainment systems and consumer electronics.

Problems solved by this technology:

  • Non-linear distortion in audio signals can degrade sound quality and accuracy.
  • This circuit compensates for such distortion, resulting in improved audio fidelity.

Benefits of this technology:

  • Enhanced audio quality with reduced non-linear distortion.
  • More accurate reproduction of audio signals.
  • Improved listening experience for users.
  • Potential for better audio production and recording quality.


Original Abstract Submitted

a non-linear distortion compensation circuit includes: a first input terminal of a linear dynamic circuit is configured to input an audio signal, and an output terminal is separately connected to a first input terminal of a gain module and a first input terminal of a multiplier; a second input terminal of the gain module is configured to input the audio signal, and an output terminal is connected to a second input terminal of the multiplier; an output terminal of the multiplier is connected to a first input terminal of a non-linear inverse dynamic circuit; a second input terminal of the non-linear inverse dynamic circuit is configured to input the loudspeaker model parameter, and an output terminal is connected to a loudspeaker. a compression gain that is output by the gain module is used to compress, by using the multiplier, a linear signal that is output by the linear dynamic circuit.
