ABSTRACT:
A speaker system for a small radio device includes a cover plate having slots therein and a rigid grille screen having channels which extend into the slots. The cover plate and grille screen are generally planar and parallel to each other, and the channels in the screen have portions generally perpendicular to the plate and screen which are spaced from the edges of the slots, with openings therein through which sound is transmitted. A felt disc is positioned over the screen, and the speaker is positioned against the felt disc. An annular bracket engages the speaker rim and is secured to the cover plate to hold the speaker system assembled. The bracket is of semi-circular cross-section with the flat side thereof engaging the speaker, and has integral extensions which are secured to the cover plate to clamp the speaker against the felt disc.
