TECHNIQUES FOR DYNAMICALLY MANAGING A LOW-FREQUENCY SOUND FIELD USING NON-LOW-FREQUENCY LOUDSPEAKERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240045644 titled 'TECHNIQUES FOR DYNAMICALLY MANAGING A LOW-FREQUENCY SOUND FIELD USING NON-LOW-FREQUENCY LOUDSPEAKERS

Simplified Explanation

The disclosed embodiments of this patent application describe techniques for generating a low-frequency sound field for an audio system. A computing device in the audio system determines the first playback level of an audio input, which is lower than the maximum playback level of the audio system. Based on this first playback level, the computing device retrieves one or more first parameters associated with a first loudspeaker in the audio system. These parameters decrease the first cutoff frequency of the first loudspeaker to a second cutoff frequency. The computing device then modifies a first portion of the audio signal transmitted to the first loudspeaker to decrease the first cutoff frequency to the second cutoff frequency based on the retrieved parameters.

  • The patent application describes a method for generating a low-frequency sound field in an audio system.
  • A computing device in the audio system determines the first playback level of an audio input.
  • The computing device retrieves one or more first parameters associated with a first loudspeaker in the audio system.
  • These parameters decrease the first cutoff frequency of the first loudspeaker to a second cutoff frequency.
  • The computing device modifies a first portion of the audio signal transmitted to the first loudspeaker based on the retrieved parameters.

Potential applications of this technology:

  • Enhancing the low-frequency sound experience in audio systems.
  • Improving the overall audio quality and immersion in home theater systems.
  • Optimizing the performance of audio systems in large venues or auditoriums.

Problems solved by this technology:

  • Inadequate low-frequency sound reproduction in audio systems.
  • Difficulty in achieving optimal bass response in different listening environments.
  • Limited control over the cutoff frequency of loudspeakers in audio systems.

Benefits of this technology:

  • Enhanced low-frequency sound reproduction for a more immersive audio experience.
  • Improved bass response and overall audio quality in various listening environments.
  • Greater flexibility and control over the cutoff frequency of loudspeakers in audio systems.


Original Abstract Submitted

disclosed embodiments include techniques for generating a low-frequency sound field for an audio system. a computing device in the audio system determines that a first playback level of an audio input is less than a maximum playback level of the audio system. based on the first playback level, the computing device retrieves one or more first parameters associated with a first loudspeaker included in the audio system, where the one or more first parameters decrease a first cutoff frequency of the first loudspeaker to a second cutoff frequency. the computing device modifies a first portion of an audio signal transmitted to the first loudspeaker to decrease the first cutoff frequency to the second cutoff frequency based on the one or more first parameters.
