Abstract

Abstract Prenatal audio apparatus includes a belt for fitting over a pregnant woman for directing audio sounds to the unborn baby. A belt has an inside surface, to fit against a pregnant woman's body, and an outside surface. Belt fasteners, such as hook and loop material, may adjustably attach the belt to the person. The belt can be made of a soft loop material fastenable for a hook material fastener portion. An audio signal source, such as a small portable tape recorder, is attachable to the belt. A pair of audio transducers are mounted in the belt in foam material with the output of the transducers facing the belt's inside surface, so that when attached to the patient, the sounds will be directed toward the unborn baby. The audio transducer is operatively connected to the audio signal source. The audio signal source may also be connected to earphones worn by the woman carrying the baby.
