NOISE CANCELLATION BASED ON AIRFLOW GENERATOR OPERATIONAL SPEED - A simplified explanation of the abstract

This abstract first appeared for US patent application 17805996 titled 'NOISE CANCELLATION BASED ON AIRFLOW GENERATOR OPERATIONAL SPEED

Simplified Explanation

The patent application describes an electronic device that includes an audio output device, an airflow generator, and a system controller. The device also includes an audio controller that generates a noise cancellation audio output based on the operational speed of the airflow generator, as indicated by the system controller. This noise cancellation audio output is then sent to the audio output device to reduce the noise produced by the airflow generator.

  • The electronic device has an audio output device, airflow generator, system controller, and audio controller.
  • The airflow generator generates an airflow, and the system controller controls its operational speed.
  • The audio controller generates a noise cancellation audio output based on the operational speed of the airflow generator.
  • The noise cancellation audio output is sent to the audio output device to mitigate the noise produced by the airflow generator.

Potential Applications

  • This technology can be applied in electronic devices that have airflow generators, such as cooling fans in computers or air conditioning units.
  • It can be used in audio equipment to reduce the noise generated by internal fans or other airflow mechanisms.

Problems Solved

  • The technology solves the problem of noise generated by airflow generators in electronic devices, which can be distracting or annoying to users.
  • It addresses the need for noise cancellation in devices where airflow is necessary but can cause unwanted noise.

Benefits

  • The noise cancellation audio output helps to mitigate the noise produced by the airflow generator, providing a quieter and more pleasant user experience.
  • Users can enjoy the benefits of airflow in electronic devices without the accompanying noise disturbance.
  • The technology improves the overall quality and usability of electronic devices by reducing unwanted noise.


Original Abstract Submitted

In some examples, an electronic device includes an audio output device, an airflow generator to generate an airflow, and a system controller to control an operational speed of the airflow generator. The electronic device further includes an audio controller to generate a noise cancellation audio output based on an indicator of the operational speed of the airflow generator provided from the system controller to the audio controller, and send the noise cancellation audio output to the audio output device to mitigate noise produced by the airflow generator.
