US Patent 7942753 Play apparatus with integrated sound producing mechanism

A sound producing play apparatus includes a support structure, an air compression system, a movable member, and a sound generating mechanism. In operation the air compression system harnesses energy from a user's movement of the movable member to create a forced supply of wind. The wind is then passed through a series of tubes and air reservoirs to a sound producing mechanism to create the desired sound. The air compression system includes an air compressor that is positioned inside a portion of the support structure to protect the air compressor from damage.
