Abstract
A noisemaker assembly that includes an annular horn body having an inner wall, an outer wall and a groove disposed there between. The groove is open at the top surface of the horn body. A tubular mouthpiece is provided that extends into the horn body. The mouthpiece communicates with the groove inside the horn body. When air is blown into the mouthpiece, that air passes into the groove within the horn body. A membrane is placed over the horn body so that the membrane covers the top of the groove. When air is blown into the groove, the air slips past the membrane from inside the groove. This causes the membrane to vibrate and generate a loud low frequency noise. The horn assembly can be held within a housing. The housing has perforations to enable sound energy from the horn assembly to escape from the housing.
