ABSTRACT:
A whistle is provided which will create two frequencies when blown to produce a beat. The whistle has a mouthpiece defining an inlet opening and an inlet passageway extending axially from the inlet opening to a main body which has two similar chambers extending generally axially. Air from the passageway engages two splitter edges associated one with each of the chambers. A lanyard receiver extends axially from the main body remote from the mouthpiece and defines a transverse cavity connected to one of the axial chambers. The whistle is made from first and second parts having mating peripheral surfaces where a joint is made. The arrangement of the whistle is such that two resonant frequencies are created each having a different audible frequency to create a beat. This is achieved in a simple, light and compact structure which is simple to assemble resulting in a relatively inexpensive whistle having good sound characteristics.
