Title:
ACOUSTIC METAMATERIAL BASIC STRUCTURE UNIT AND COMPOSITE STRUCTURE THEREOF, AND CONFIGURATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/041283
Kind Code:
A1
Abstract:
An acoustic metamaterial basic structure unit comprises a boundary limit frame (1), an in-frame limit member (2) configured in the boundary limit frame (1), and a thin film (3) covered on at least one of an upper surface and a lower surface of the boundary limit frame. Also provided are an acoustic metamaterial board comprising the acoustic metamaterial basic structure unit, an acoustic composite structure comprising the acoustic metamaterial basic structure unit, and a method realizing a soundproofing frequency band adjusted according to a working frequency of an acoustic metamaterial by changing a structure size and a material parameter of the boundary limit frame (1), the in-frame limit member (2), and a thin film (3) of the acoustic metamaterial. The embodiments has advantages of being simple to install, a long service life, and restraining a thin film vibration mode, enhancing performance stability of a soundproof material.
