Signal Limit Based On Detecting Clipping - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048897 titled 'Signal Limit Based On Detecting Clipping

Simplified Explanation

The patent application describes a technique for controlling a passive radiator in a device that receives audio content and generates an audio signal representing the content. The technique involves modifying portions of the audio content to prevent the speaker driver from moving beyond its excursion limit. The device also detects clipping of the speaker driver and adjusts a forward prediction model based on the detected clipping.

  • The technique involves controlling a passive radiator in a device that receives audio content and generates an audio signal representing the content.
  • The device modifies portions of the audio content to limit the excursion of the speaker driver when predicted to move beyond the excursion limit.
  • The device detects clipping of the speaker driver and generates a feedback signal based on the detected clipping.
  • The device adjusts the forward prediction model based on the generated feedback signal.

Potential applications of this technology:

  • Audio devices such as speakers, headphones, and soundbars could benefit from this technology to prevent speaker driver damage and improve audio quality.
  • Automotive audio systems could use this technology to optimize speaker performance and prevent distortion.
  • Home theater systems could benefit from this technology to enhance the audio experience and protect the speakers from damage.

Problems solved by this technology:

  • Prevents speaker driver excursion beyond the limit, which can cause distortion and damage to the speaker.
  • Improves audio quality by modifying portions of the audio content to prevent clipping and distortion.
  • Allows for better control and optimization of speaker performance.

Benefits of this technology:

  • Protects the speaker driver from damage by limiting excursion beyond the specified limit.
  • Enhances audio quality by preventing clipping and distortion.
  • Provides better control and optimization of speaker performance.
  • Improves the overall audio experience for users.


Original Abstract Submitted

example techniques may involve controlling a passive radiator. an implementation may include a device receiving, via a network interface, audio content and generating an audio signal representing the audio content. generating the audio signal involves modifying portions of the audio content to limit excursion of the speaker driver to less than an excursion limit when a forward prediction model indicates that the portions of the audio content are predicted to cause the speaker driver to move beyond the excursion limit. while playing back the generated audio signal via the audio stage, the device detects, via a sensor, clipping of the speaker driver and generates a feedback signal based on the detected clipping of the speaker driver. the device adjusts the forward prediction model based on the generated feedback signal.
