A recently granted patent (Publication Number: US11986849B2) discloses an innovative air amplifier system designed to utilize energy from a high-pressure input stream of gas to accelerate a low-velocity input stream of gas, resulting in a high-velocity, high-volume output stream of gas. The system includes an air guide with a first faceplate that shapes the gas stream and allows unwanted noise to pass through, an active acoustic absorption chamber with acoustic suppression elements that generate noise suppression waves, and a second faceplate to complete the assembly.

Furthermore, the patent details various configurations and features of the air amplifier and air guide, including the use of perforations in the faceplate to allow noise propagation, the arrangement of acoustic suppression elements in a two-dimensional lattice pattern, and the vibration of these elements at resonant frequencies to enhance noise suppression. The air guide is designed with a hollow cavity, inner and outer faceplates, and the active acoustic absorption chamber to effectively manage and reduce unwanted noise generated during the gas flow process. These innovative features aim to improve the efficiency and performance of air amplification systems in various applications.
