Abstract
The present invention relates to a light and sound emittable dartsboard which has a bottom member on which a central induction board, a cell compartment, speakers, etc. are disposed, a top member which is adapted to be covered over the bottom member and may have a top protective layer showing different patterns. The bottom member has a plurality of bulbs disposed around its periphery such that each of the bulbs may project from a hole correspondingly formed on the top member. The top member has a switch control means the lower end of which is shortly above the induction board such that the switch control means shall contact the induction board and connect the circuit thereof when the switch control means is hit by a dart. At this point, the dartsboard shall emit preset sound and the bulbs shall flash at random for a period of time before all of them but one extinguish. The bulb that keeps on shall indicate a certain score or mark as shown on the top protective layer corresponding to the lighting bulb.
