  • Patent number: 6039626
    Abstract: A voice activated toy truck having animated features includes a truck chassis that supports a hood and cab that readily flexes and bends and that may have an exterior surface molded in the shape of a set of facial features. The truck chassis supports a truck bed carrier that supports a truck bed. The truck bed is mounted to the carrier in a movable fashion such that the truck bed is capable of movement in a side-side fashion relative to the truck chassis. A first actuator assembly causes the flexible hood to flex thereby causing the facial features to move and a second actuator assembly causes the truck bed to move in the side-to-side fashion that emulates a puppy dog wagging its tail. A sound detecting circuit actuates a control circuit that is coupled to the first and second actuator assemblies and that causes the first and second assemblies to operate in the manner described.
