ABSTRACT:
A portable apparatus for soothing infants to enable them to fall asleep utilizes a portable housing having a cylindrically-shaped intake and exhaust opening coupled by a hollow cylindrical tube into which is located a miniature motor disposed proximate the intake opening with fan blades affixed on the rotating motor shaft that provides an air flow over a plurality of flexible members disposed proximate the exhaust opening. A control arrangement, coupled to a battery power source, is disposed within the housing for controlling the amount of forced air flowing out of the exhaust opening so that the tone or the sounds emanating from the apparatus can be controlled.
