Abstract
(EN)
Provided in embodiments of the present disclosure are an array substrate and a sound generation device, the array substrate comprising: a base substrate, and an elastic layer, piezoelectric layer, and first matching layer that are located on the base substrate and that are stacked in sequence; the array substrate comprises a sound generation region and a non-sound generation region; the base substrate is provided with a plurality of first hollow cavity structures at least within the sound generation region; the pattern of the sound generation region is centrosymmetric, and the center of symmetry of the sound generation region and the center of symmetry of the base substrate are located in the same region; and the orthographic projection of the first matching layer on the base substrate overlaps with the sound generation region.
