  • Acoustic meta-material basic structure unit, composite structure thereof, and assembly method
    Patent number: 11158299
    Abstract: This invention provides an acoustic metamaterial unit cell, consisting of a frame, a constraint stick placed in the frame and a piece of membrane covering at least one surface of the frame. This invention also provides an acoustic metamaterial plate comprised of the provided unit cells and a composite structure of acoustic materials. Additionally, the invention provides a method to design the operating frequency bands by modifying the structure and material properties of the frame, the constraint stick and the membrane in the proposed acoustic metamaterial. The proposed structure shows a priority in fabrication, stability and service life.
