Document Type and Number:
WIPO Patent Application WO/2024/038683
Kind Code:
A1
Abstract:
A structure according to one aspect of the present technology comprises a housing, a pressure generation device, and an acoustic metamaterial. The housing has at least one opening. The pressure generation device is disposed within the housing and generates air pressure toward the opening. The acoustic metamaterial is fitted into the opening, has a first through-hole formed such that the air pressure linearly passes therethrough, and a second through-hole formed such that the air pressure spirally passes therethrough, and is formed such that the ratio of the sum of the cross-sectional area of the first through-hole and the cross-sectional area of the second through-hole to the cross-sectional area in the pressure generation device is less than 0.94.
