Abstract
A low profile miniature speaker configured for use in greeting cards such as sound generating greeting cards and other novelties. The thickness of the speaker is minimized while maintaining the sound quality and increasing strength. The speaker magnet is counter-sunk into the housing of the speaker, thereby decreasing overall thickness. The speaker is configured with concentric ribs that radiate outward from the center of the circular speaker. The ribs reinforce the plastic housing and increase the structural strength of the speaker.
