Abstract
A sound wave metamaterial amplifies a sound wave, and includes a plate. The plate has a plurality of sound wave guides passing through both surfaces of the plate and having a predetermined pattern. The sound wave guides are spaced apart from each other by a predetermined distance and face each other, with respect to a central point, a central axis or a central surface.
Claims10
A sound wave metamaterial configured to amplify a sound wave, the sound wave metamaterial comprising:
- a plurality of plates, each of the plates having a predetermined thickness and an upper surface and a lower surface, a plurality of sound wave guides being formed between the upper and lower surfaces of the plate,
- wherein
- each of the sound wave guides passes through the upper and lower surfaces of the corresponding plate and has a predetermined pattern,
- the sound wave guides adjacent to each other are spaced apart from each other along an extending direction of the upper and lower surfaces of the plate, and
- the plates adjacent to each other are spaced apart from each other to form a space in which the sound wave guides are not disposed.
