ABSTRACT:
A sound generating pacifier for use by an infant which comprises a pacifier body having a first end and a second end with an air passageway extending therebetween. The pacifier body defines a pacifier guard for preventing in use the infant from choking on or swallowing the pacifier. A nipple is disposed at the first end of the pacifier body. The nipple further includes an aperture formed therein to enable in use air communication between the mouth of the infant and the air passageway of the pacifier body. A sound generating means for directly generating a sound upon a flow of air therethrough is positioned at the second end of the pacifier body. The sound generating means is in air communication with the air passageway of the pacifier body. A one-way valve means inhibits in use the flow of air through the air passageway of the pacifier body and into the mouth of the infant when the infant sucks on the nipple and enables in use the expired air from the mouth of the infant to flow through the aperture of the nipple, the air passageway of the pacifier body, the one-way valve means and the sound generating means to exit the sound generating means thereby generating sound.
