Abstract: A miniature fan is mounted on a printed circuit board (PC board) and circulates air to help dissipate heat in enclosed electronic packages. The fan blades may rotate in a direction parallel or perpendicular to the plane of the PC board depending on available space. The method of mounting the miniature fan may be incorporated directly into the presently existing methods by which electrical components are mounted on a PC board, and which simplifies the mounting and manufacturing process such that mounting screws, lead wires, connectors, etc are eliminated, thus increasing efficiency and reducing cost.

Abstract: A miniature loud speaker mounted on a frame, the frame having prongs which fit into holes of a printed circuit board, the prongs having step changes which permit the speaker to be spaced an adjustable distance from the surface of the printed circuit board, and the frame and prongs formed together as one unified structure.
