Abstract: An audio device and an electronic instrument are provided by which a device case can be downsized. An elastic member is interposed between an attachment hole provided in a panel-side sealed frame section of a speaker panel and a projection section of a speaker grill and, in this state, the speaker grill is fixed to the speaker panel by the projection section being subjected to torsion deformation. By the elastic member being deformed inside the attachment hole and coming in close contact with the surface of the projection section and the inner surface of the attachment hole, the attachment hole that is a through hole is filled. As a result of this structure, an attachment hole that is used when a speaker grill is attached to a speaker panel can be arranged at a position where it penetrates to an acoustic space.
