ABSTRACT:
An infant pacifier with a diaphragm melody generator in which only when the infant holds the pacifier in the mouth and sucks or mumbles, a diaphragm switch of the melody generator is operated in order to permit the generator to generate melody. The present pacifier comprises a nipple part for being held by the infant mouth, a handle part for permitting the pacifier to be handled and a melody generator. The melody generator comprises a diaphragm switch for turning on/off the melody generator in accordance with the holding force and an electronic circuit board for generating the melody in cooperation with the diaphragm switch when the infant holds the nipple part of the pacifier in the mouth. The diaphragm switch is applied with conductive ink at its center and easily expanded and contracted by the holding force. The electronic circuit board has a switching portion, at which positive and negative terminal wires are provided such that they are normally spaced apart from each other, at its center and is disposed such that it is minutely spaced apart from the diaphragm switch.
