ABSTRACT:
The disclosed stereo sound pillow has a resilient interior fiberous composite and an essentially nonextendable exterior case completely enclosing the interior composite. Sound speakers having sound outlets from both front and rear sides thereof, and lead wires connected to each speaker, are fixed to a flexible mounting strip: and the mounting strip and speakers are surrounded by the interior composite to hold the sound speakers suspended within the interior composite, spaced apart lengthwise and from the side and end edges thereof, and the lead wires exit from the exterior case adjacent one end edge. The mounting strip allows the fast and economical fabrication of the pillow, either: as the interior composite is formed by rolling up a web of the fiberous material on itself and over the mounting strip and speakers, or after the interior composite is fitted inside of the exterior case by parting the interior composite and inserting the mounting strip and speakers into the defined cavity in the composite interior and then collapsing the cavity. The mounting strip may be made from the same material used for the resilient interior fiberous composite.
