ABSTRACT:
A simplified and efficient sound generating device consisting of a self-contained audible signaling device and a means of affording said device protection against moisture and cold temperatures, comprised of a photoelectric cell, a source of energy, a sound transducer means, and appropriate container that permits the entry of light therein. When positioned in an appropriate darkened enclosure, the device permits an immediate audible signal upon the opening of said enclosure and the introduction of light therein. Said device is particularly suited for use as an aid to behavior modification programs that are associated with the need to eliminate the habitual and compulsive over-consumption of food from the diet.
