CIRCUIT BUILDING-BLOCK FOR PASTIME AND STUDY

WIPO Patent Application WO/2006/010318

A1

The present invention discloses a circuit building-block for pastime and study, including a baseplate and at least two building-mocks having related figures and characters. An acousto-optic circuit is disposed in the baseplate, the circuit is provided with two main contacts for loop closing. The respective building-blocks are spliced between the two main contacts located on the surface of the baseplate . The respective building-blocks located on both sides are provided with leadin contacts, respectively, which contact the main contacts on the baseplate, respectively. The splicing sides of the respective building-blocks are provided with splicing contacts, respectively, which can contact each other. The corresponding contacts of each building-block are connected by wires The spliced building-blocks and the acousto-optic circuit on the baseplate constitute a closing loop. The present invention combines organically the building-blocks with the circuit, the spliced building-blocks and the acousto-optic drive circuit on the baseplate constitute the closing loop thereby generating acousto-optic information, improving further visual effect and inducting aural effect. The present invention makes the building-blocks have innervation thereby improving the interest of children and enhancing the efficacy of intelligence development.
