Abstract

Of the type that incorporate a plurality of orifices (2 and 2'), and that furthermore include in their rear side a series of reinforcing ribs. It is characterized in that the reinforcing ribs are determined by a plurality of straight ribs (3) parallel and equidistant among them which are located at the space comprised between two lines of orifices, which are complemented and interlaced with some curved ribs (4) forming an "S" shape which run along a line of orifices, surrounding them alternatively. The arrangement of the ribs prevents them to be seen from outside, while simultaneously improve the mechanical resistance to breakage and the fidelity of sound.
