ABSTRACT:
A music box having a hollow base within which a power supply and a driving mechanism are installed. A platform is rotatably mounted on the base to be driven by the driving mechanism on which a music playing doll and a dancing doll are movably and rotatably mounted. Each of the dolls has a driving rod secured thereon and the driving rods are guided by an activity generation plate which is disposed under the platform and driven by the driving mechanism to move and rotate the dolls. The activity generation plate has a circumferential groove in a wavy form in a plane parallel with the activity generation plate to receive therein an offset extension of one of the driving rods so as to move the extension portion in a radial direction and thus rotate the driving rod forth and back as the activity generation plate rotates. The activity generation plate further includes several ridge portions thereon to move the other driving rod up and down when the activity generation plate rotates.
