摘要： A magnetic dart board that includes embedded conductor coils beneath scoring areas. When a dart with a magnetic head strikes a scoring area of the dart board a current is induced in the underlying conductor coil. The induced current provides an electrical signal that is transmitted to an automatic scoring system that calculates and displays scores. The dart board is made from a plurality of layers including a top layer, an insulating layer, a sensing layer and a body layer. The multi-layered dart board is flexible and can be rolled up for storage, shipping and transportation.
