Abstract
A speaker grill includes a diffusion plate, a base, and a support portion. The diffusion plate forms an opening facing a speaker and is arranged on an outer side of the opening so as to form a concave shape in a sound-emitting direction of the speaker. The base supports the diffusion plate at an outer circumference thereof. The support portion is provided at a front surface of the diffusion plate in the sound-emitting direction, having a support surface that covers at least a portion of the front surface of the diffusion plate, and having a plurality of partition walls forming slits in the sound-emitting direction. The support surface forms a virtual surface that covers an outer surface of the base.
