Abstract
Abstract A model horse is resiliently mounted to permit a child rider to cause motion of the horse having vertical and/or horizontal motion components. A trotting gait sound is generated in response to detected vertical motion, and a walk and/or gallop gait sound is generated in response to detected horizontal motion. The selection as between the walk and gallop gait is preferably based upon the amplitude or horizontal motion. The different gait sounds are obtained by generating a basic "clop" (hoofbeat) sound, and, repeating the clop sound in a different time sequence for each gait. In the preferred embodiment of the invention, the sounds of a horse's "snort" and "whinny" are also generated during riding. The sounds produced in accordance with the invention are obtained by digitally forming audio frequency signals and controlling the envelope of the audio frequency signals.
