Blanket with recordable heart beat

Abstract

A blanket which incorporates apparatus for recording and playing back sounds of a beating heart, for soothing babies. The blanket has a pocket which receives a sound generator including a microprocessor chip, an e-prom memory chip, a piezo speaker, a solid state pick up transducer, a miniature battery cell, and preferably three control pushbuttons. Two of the pushbuttons must be pressed simultaneously to activate the recording function. The shut off function is similarly controlled, with different pushbuttons. Optionally, the pick up transducer is connected to the sound generator by a cable having a manually removable connector. In another option, a radio frequency transmitter is operably connected to the sound generator to enable operation as an audible monitor when the recording function is also activated.
