ABSTRACT:
A plurality of dummy bores with bottoms (21) are disposed in the vicinity of through holes (11) defining speaker sound emanating apertures. Each dummy bore (21) has a bottom shaped like a cone or pyramid (23) such that outer light rays (31) becoming incident through the dummy bores (21) are irregularly reflected from the bottom to emerge therefrom as decreased in intensity. With the above arrangement, the through holes (11) and dummy bores (21) may appear less differently from each other. Thus provided is a speaker grille of excellent design.
