In the seventh embodiment, compared with the sixth embodiment, the difference is that the third coil (not shown) disposed at the outer edge of the inner single-sized section 3 is reduced, in other words, the first coil 91, the second coil 92, the fourth coil 94, the fifth coil 95, the sixth coil 96, the seventh coil 97, the eighth coil 98, the ninth coil 99 and the tenth coil 9A are wound in the same manner as the sixth embodiment, so that the details are not described herein in order to avoid redundancy.
As shown in fig. 32, the induction coil assembly 9 further has an eleventh coil 9B disposed around the outer edge of the dead zone 7.

As shown in fig. 2 and 34, the dartboard 10 further includes a dart K, which is composed of a dart rod K1, a dart wing K2 disposed at one end of the dart rod K1, and a metal dart head K3 disposed at the other end of the dart rod K1 and opposite to the dart wing K2, wherein the metal dart head K3 is magnetized after contacting a magnet, so that the dart K is thrown at a dividing area of the dart target 10, and when the dart K darts, a coil corresponding to the dividing area outputs an electrical signal to the amplifier circuit B, the filter component C, and the digital signal processor D in an inductive manner, so as to serve as a scoring or other operation basis.
Since the induction coil group 9 is arranged on the dart target 10, when a user injects the dart K with the magnetically polarized metal dart head K3 into the dart target 10, the magnetic flux originally formed by the induction coil group 9 changes at the moment of insertion, so that the induction coil group 9 can generate induction current due to the change of the magnetic flux, and the induction coil group 9 can perform signal processing through a related circuit, thereby achieving the effect of automatic scoring of the electromagnetic induction target.
Secondly, because the magnetic polarization can be realized only by contacting the metal dart head K3 with a magnet, the dart which can be used by a user can have larger selectivity, is not limited to the dart with the magnetic dart head, and can also be the dart with the ordinary metal dart head, such as iron or the alloy thereof, not only improves the degree of freedom of the user in use, but also reduces the difficulty and the cost in manufacturing, and ensures that the product has more market competitiveness.
The methods, effects and efficacies of the present invention are described in detail above; the above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the invention, so that the present invention shall be covered by all modifications and variations within the scope of the equivalent effect.
