<p>The invention discloses an electronic dartboard and a magnetic dart. A magnetic bod3 is fixed at the head of the dart, and the head has a flat end surface. The dartboard comprises of a target surface layer, an insulating layer, a film printing coil layer, an absorption layer, and a target bottom layer. Those layers are fixed in turns. Scoring cricuits are arranged in the dartboard. Some lattice areas are printed on the targei surface layer. Single turn coils are set up on the film printing coil layer independently, each of which coressponds to one lattice area on the target surface layer.A definite distance is set between the adjacent coils, and the distance is slightl5 smaller than the diameter of the head of the dart. Tail wires of each coil are connectec to the scoring circuits respectively. Ferro material bodies are provided on the absorption layer area, which coresspond to the lattice areas of the target surface layer. This structure makes the manufacturing technique of the dartboard become simple, is; easy to realize, and has a better effect in use. The magnetic induction scoring method ensures the whole esthetic appearance of the dartboard surface and provides better effect in use.</p> |
