Abstract
A loudspeaker grille made of stiff material, such as stiffened grille cloth, has at least a major proportion of the length of its edge so shaped that, when seen in cross section, one part 2 extends rearwardly, approximately perpendicularly to the plane of the grille, and another part 3 returns forwardly again from the rear edge of the first part and at an acute angle to the first part so as to present a free edge lying to the rear of the plane of the grille and outwardly of the first part. Both parts of the edge portion, when seen in cross section, may be straight and define a generally V-shaped configuration of which the included angle may be between 30 degrees and 45 degrees prior to fitting the grille in position in a loudspeaker. The edge portion is then held in a groove 10 in the housing 11, 13 of a loudspeaker as a result of the resilience of the edge portion. <IMAGE>
