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.
