The device automating the vertical, lateral and gyratory movements of the doll is based on a low frequency sensor (3) influencing an electronic system (1). The system is powered either by a battery (2), a mains socket, a solar panel or a wind power generator. Vertical jumps are instigated by a coil (4) surrounding a magnetic core (5) on a spring (13). Sideways movements are created by a separate coil (8) and a core (7), and gyrations are produced by a third coil (9) and a toothed wheel (10) pivoting the support (11) through 360 degrees. The assembly is concealed under the dress of the doll, which is mounted on a wooden, metallic or plastic base (6).
