The invention provides a noise-maker having an injection molded single
piece body, a membrane and a retaining ring. The injection molded single
piece body includes a generally cylindrical central tube and a generally
cylindrical pressure tube which defines a pressure chamber. The retaining
ring has an inner diameter adapted to fit over the outer surface of said
pressure tube such that the membrane is secured to and stretched across
the central tube first end and the pressure tube first end. Sound is
created when air or other gas is forced into pressure chamber. The air
must pass through the pressure chamber around a central tube first end and
out the discharge end of a sound extension end. By forcing air into the
pressure chamber, membrane vibrates producing a loud sound.
