SUPPORT COMPONENT AND SPEAKER UNIT

WIPO Patent Application WO/2024/090231

A1

This support component 6 comprises: a plurality of planar parts 30 that are aligned at intervals in a plate-thickness direction; a plurality of first peripheral-edge connecting parts 31 each of which connects two planar parts 30 adjacent to each other in the plate-thickness direction in a first range of the periphery direction of the planar parts 30 along the peripheral edges of the planar parts 30 as seen in the plate-thickness direction; and a plurality of second peripheral-edge connecting parts 32 each of which connects two planar parts 30 adjacent to each other in the plate-thickness direction in a second range of the periphery direction of the planar parts 30 along the peripheral edges of the planar parts 30 as seen in the plate-thickness direction. The length of each of the first peripheral-edge connecting parts 31 and the length of each of the second peripheral-edge connecting parts 32 in the periphery direction each are shorter than the length of the whole peripheral edge of each of the planar parts 30. The first peripheral-edge connecting parts 31 and the second peripheral-edge connecting parts 32 are alternately placed in the plate-thickness direction. As seen in the plate-thickness direction, each of the first peripheral-edge connecting parts 31 and a respective one of the second peripheral-edge connecting parts 32 are so arranged as to be continuous with each other in the periphery direction.
