Title:
ACOUSTIC LENS AND SPEAKER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/219053
Kind Code:
A1
Abstract:
This acoustic lens (1) comprises an opening (10) and a plurality of partitioning plates (11). A sound wave to be emitted from a speaker is input into the opening (10). The plurality of partitioning plates (11) forms a plurality of sound paths (P1) that the sound wave input into the opening (10) passes through. The plurality of partitioning plates (11) comprises a first control mechanism (plurality of first partitioning plates (111)) and a second control mechanism (plurality of second partitioning plates (112)). The first control mechanism controls the directivity in a first direction (d1) of the sound wave that passes through the plurality of sound paths (P1) and is externally output. The second control mechanism controls the directivity in a second direction (d2), which intersects with the first direction (d1), of the sound wave that passes through the plurality of sound paths (P1) and is externally output.
