SHROUD FOR AN AIR MOVING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17826686 titled 'SHROUD FOR AN AIR MOVING DEVICE

Simplified Explanation

The abstract describes a shroud for an air moving device that helps reduce noise generated by the device.

  • The shroud body partially surrounds the blades of the air moving device.
  • It has an annular cavity and an annular opening facing the blades.
  • The shroud includes a Helmholtz resonator formed by the annular cavity and opening.
  • The Helmholtz resonator is designed to reflect the sound produced by the blades out of the shroud body.
  • The purpose of this innovation is to minimize the noise generated by the air moving device.


Original Abstract Submitted

A shroud for an air moving device includes a shroud body configured to at least partially surround one or more blades. The shroud body defines an annular cavity and an annular opening. The annular opening faces the one or more blades. The shroud also includes a Helmholtz resonator defined by the annular cavity and the annular opening. The Helmholtz resonator is configured to reflect sound generated by the one or more blades out of the shroud body.
