or shoulders of a child for u201c horsey u201d or u201c piggy back u201d play when used the doll will magically emit galloping or and or neighing sounds referring particularly to fig1 integrated circuit u 1 is a typical commonly available u201c voice ic u201d having the capacity to playback stored digitized sounds subject to the control of a software program the circuitry particularly depicted in support of this function are oscillator r 3 bias resistor r 4 amplified q 1 loudspeaker spkr and battery b 1 this circuitry is well known in the prior art and is incorporated into the instant invention as an old element making up part of a novel combination circuit u 1 also embodies a number of trigger inputs tg 1 tg 2 and tg 3 the circuit can thereby be configured to recognize logic states and or transitions at these inputs and accordingly execute various other diverse software routines in the depicted most preferred embodiment s 1 is a motion sensor for detecting the u201c bouncing u201d motion of a child acting out the part of a horse however to further facilitate u201c horsey u201d play it would also be desirable to provide continuous playback of galloping sound effects as long as motion is detected thus the preferred embodiment of the invention includes an averaging circuit comprised of r 1 r 2 and c 1 inserted between s 1 and the tg 1 of u 1 the averaging portion of the circuit is designed to provide continuous activation.
