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

This abstract first appeared for US patent application 17816171 titled 'BACKPLANE-ATTACHED ACOUSTICALLY REACTIVE ELEMENTS

Simplified Explanation

The patent application describes a system for reducing acoustic noise in the chassis of an information handling system by generating reactive acoustic energy. Here are the key points:

  • The system includes acoustically reactive elements positioned relative to a backplane with multiple openings.
  • Each acoustically reactive element consists of 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 frequency determined by the parameters of the acoustically reactive element.

Potential Applications:

  • This technology can be applied to information handling systems, such as computers, servers, or data centers, to reduce the acoustic noise generated by the airflow within the chassis.
  • It can also be used in other electronic devices or equipment where noise reduction is desired, such as audio equipment, appliances, or industrial machinery.

Problems Solved:

  • Acoustic noise generated by the airflow within the chassis of information handling systems can be disruptive and affect the user experience.
  • This technology addresses the problem of excessive acoustic noise by generating reactive acoustic energy that cancels out or reduces the noise.

Benefits:

  • Improved user experience by reducing the acoustic noise level in information handling systems or other electronic devices.
  • Enhanced productivity in environments where noise reduction is crucial, such as offices or data centers.
  • Increased comfort and reduced distraction for users working in close proximity to the information handling system or electronic device.


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
