Abstract:
1. A device for generating sounds associated with movements of animals, the device comprising: a movable member operatively associated with a motion generation system and configured to be set in a desired motion by the motion generation system, and an extension assembly configured to replicate a leg of an animal and including an upper portion pivotally mounted relative to a pivot point and a lower portion connected to the movable member for being driven by the movable member in a desired path for contact with a desired contact medium to generate sounds that mimic sounds associated with movements of animals, wherein the extension assembly includes a connection joint which connects the upper and lower portions of the extension assembly, and a joint spring which extends between the upper and lower portions of the extension assembly, wherein the connection joint functions as a hinge and the joint spring creates a moment about the connection joint that urges the lower portion of the extension assembly to remain in substantially continuous contact with the contact medium as the extension assembly travels through the desired path.
