SOUND ABSORBING DEVICES AND ACOUSTIC RESONATORS DECORATED WITH FABRIC - A simplified explanation of the abstract
This abstract first appeared for US patent application 17851422 titled 'SOUND ABSORBING DEVICES AND ACOUSTIC RESONATORS DECORATED WITH FABRIC
Simplified Explanation
The abstract describes a sound absorbing device that includes a chamber with an opening and at least one fabric layer extending across the opening. The fabric layer can be either stacked in direct contact with each other or spaced apart by a predefined distance. Additionally, there can be an elastic fabric layer that vibrates independently from the chamber. The fabric layers are configured to move relative to each other.
- The sound absorbing device includes a chamber with an opening and fabric layers.
- The fabric layers can be stacked in direct contact with each other or spaced apart by a predefined distance.
- There can be an elastic fabric layer that vibrates independently from the chamber.
- The fabric layers are configured to move relative to each other.

Original Abstract Submitted
A sound absorbing device includes a chamber with an opening and at least one fabric layer extending across the opening. The at least one fabric layer extending across the opening is at least two fabric layers stacked relative to and in direct contact with each other, at least two fabric layers stacked relative to and spaced apart from each other by a predefined distance, at least one elastic fabric layer configured to vibrate independently from the chamber, or a three dimensional fabric layer. The at least two fabric layers stacked relative to and in direct contact with each other and the at least two fabric layers stacked relative to and spaced apart from each other by a predefined distance are configured to move relative to each other, and the at least one elastic fabric layer is configured to vibrate independently from the chamber.
