Horn noise maker

When the two base boards are pulled apart against the pressure of the spring, and then released, as they come together air is forced out through the horn. As a result of the spiral metal (on the left hand side of the photograph) altering the speed of the base boards coming together, the horn produces a very impressive squawk.
