BACKPLANE-ATTACHED ACOUSTICALLY REACTIVE ELEMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240040735 titled 'BACKPLANE-ATTACHED ACOUSTICALLY REACTIVE ELEMENTS

Simplified Explanation

The patent application is for a system that generates reactive acoustic energy to reduce acoustic noise in the chassis of an information handling system. It involves positioning acoustically reactive elements relative to a backplane with openings. Each acoustically reactive element has walls and an acoustical energy reducing opening. The walls create an internal volume, with at least one wall aligned parallel to the airflow direction. The acoustical energy reducing opening is oriented parallel to the airflow direction and allows the airflow to pass through, generating acoustic energy at a specific frequency based on the parameters of the acoustically reactive element.

  • The system reduces acoustic noise in the chassis of an information handling system.
  • Acoustically reactive elements are positioned relative to a backplane with openings.
  • Each acoustically reactive element has walls and an acoustical energy reducing opening.
  • The walls create an internal volume, with at least one wall aligned parallel to the airflow direction.
  • The acoustical energy reducing opening is oriented parallel to the airflow direction.
  • The airflow passing through the acoustically reactive element generates acoustic energy at a specific frequency.

Potential Applications:

  • Information handling systems such as computers, servers, or data centers.
  • Any application where reducing acoustic noise in a chassis is desired.

Problems Solved:

  • Reduces acoustic noise generated by information handling systems.
  • Improves the acoustic environment in data centers or other noise-sensitive environments.

Benefits:

  • Enhanced user experience by reducing acoustic noise.
  • Improved working conditions in noise-sensitive environments.
  • Increased efficiency and productivity by minimizing distractions caused by acoustic noise.


Original Abstract Submitted

embodiments may be generally directed to a system for generating reactive acoustic energy for reducing acoustic noise in a chassis of an information handling system. a set of acoustically reactive elements may be positioned relative to a backplane comprising a plurality of backplane openings. each acoustically reactive element comprises a plurality of walls and an acoustical energy reducing opening. the plurality of walls define an internal volume, wherein at least one wall is aligned parallel with a direction of airflow. the acoustical energy reducing opening may be oriented substantially parallel with the direction of the airflow and configured for the airflow passing the acoustically reactive element to pass the acoustical energy reducing opening to generate acoustic energy at a frequency based on the set of parameters of the acoustically reactive element
