ABSTRACT:
A noise maker having a housing with a hole formed on at least one surface of the housing and a weighted member in resilient relationship over the hole. The weighted member is movable between a first position closing the hole to a second position for allowing a desired volume of air to flow through the hole so as to produce an audible sound. The weighted member is slidably mounted on a dowel rod within the housing. A slider plate is provided with a plurality of hole sizes formed thereon. The slider plate is interposed between the hole and the weighted member. The hole is formed on a first planar surface of the housing. The housing has an opening formed on a second planar surface of the housing. The first and second planar surfaces are in parallel relationship. A chamber extends between these surfaces. The surfaces in the chamber are permanently coupled together. The chamber has a rectangular configuration.
