Abstract
A modular apparatus is provided for imparting movement and selected sound to an ornament. The apparatus includes an electronic and melody module, a mechanic transmission and power module, a base module, a power supply module, a visual module, and a melody tune integrated circuit (IC) module. The apparatus also includes a motor safety device which protects the motor from overheating and burning out when the movement of the apparatus is prohibited. The electronic and melody module includes a sound generator, a printed circuit board (PCB) assembly for controlling the output of the apparatus, and a slot receptacle for the melody tune IC card module. The mechanic transmission and power module includes a motor, a motor drive shaft, a transmission gear set connected to the motor drive shaft, and at least one axial action rod connected to the transmission gear set. The detachably connected modules provide versatility to the configuration of the apparatus.
