Playground Device with Motion Dependent Sound Feedback

Abstract

Playground device, for example a swing or a see saw, having a ground supported, movable part and at least one motion sensor configured for sensing the motion of the movable part. The motion sensor is functionally connected to a sound signal feedback generator that is configured for converting the signals from the motion sensor into a sound feedback in response to the motion of the movable part. The sensors are mechanically connected only to the movable part in order to provide system with a large number of variations of embodiments.
