The Γ Γ ☆ ☆ Although it counts money, but now the people who are more than Jian Xian are more flaming, more main props during the game. Most of the dry only have magnetic induction work. Currently, the electronic scoring darts or dust touch sensing function on the market: • 1291359 Pressure touch sensing functional product structure cooperates with the dart structure generally called the orifice plate, and the orifice plate touches it. The electronic touch circuit on the rear side causes the electronic touch circuit to sense different scores and display the scores. The conventional structure has a movable structure due to the orifice plate, regardless of the force of the orifice plate, as long as it has When the force is collided, the board surface will move and the rear side will be sent out, and the miscalculation signal will be sent. Therefore, the product with the orifice plate is a sulfur hole (4) regardless of the dart riding body, and there is a lack of scoring as long as there is a collision. The phenomenon, even if the county where the slabs of the Linlin County County danced out, the hole plate will still move the domain board scores or its darts and needles inserted into the hole _ force is too light, but less than the rotating hole The board touches the electronic circuit board for scoring. Or, if the projection force is too large, the orifice plate cannot be returned to the original position, and the _triggering score is missing; the above New Zealand will produce a false judgment score, so the electronic red fly Yuxian improvement Will be difficult Competition occasions to use. There are many improved structures for magnetic induction flying. Among them, there are many patents. The main structure is in the high-density _ outside with the induction line US5,775, the magnetic flying structure 1 flying body! (Q ) is a non-magnetic material, embedded in the front end of the flying body (丄〇) - a strong magnetic piece (11) protruding from the column type (there is also a glow on the market, phase magnetic parts appear), and recorded (i 4) The multi-channel electromagnetic coil (1 6 : 1291359 ' 2 ) cooperates with the electronic scoring secret (1 3 ) to generate an inductive scoring function, and the aforementioned micro (14) can be sensitive to the automatic magnetic component (χ i) for automatic scoring operation; After the traditional products are practical, the following problems still occur: First, the multi-channel electromagnetic coil (丄2) of the conventional dart target (14) is combined with the electronic scoring system (13) to be sensitive to any electromagnetic information, if it is a competition occasion. When someone answers the mobile phone or has electromagnetic equipment passing through, the electromagnetic coil (Work 2) will cooperate with the electronic scoring system (13) to generate false scoring, and also cause no considerations in the competition, so the current competition Still often deliberately switch to visual scoring; /, a ^ When the % recording needle is inserted into the dry body (block), the force is too light, although the fly recording body (10) is not enough to keep on the dart (1 4), but the dart is dry (1 4 ) There is still a strong magnetic piece (1 1 ) at the front end of the dart body (1 0 ). The strong magnetic piece (11) constantly causes several electromagnetic coils (i 2) to sense during the falling process and will make the electronic scoring system ( 1 3) Generate multiple repeated error scores, or 'Darts (10) projection force is too small, not only without darts, and the powerful magnetic parts (11) only touch to the dry (14)' It will also cause the electromagnetic coil (12) to be inductive, and the continuous triggering of the scoring will occur; all of the above conditions will lead to misjudgment scores, so the electronic darts target that is not used will be difficult to use in the game; 'When the dart is outside the dart target (14), the empty target is not counted, so the air dry cannot be calculated. ...... 7 1291359 Because of the accuracy of the above-mentioned electronic sensor darts, the accuracy of the scoring is very large, so some manufacturers have proposed related improvements, such as No. 89208150 of the second figure, "Improve the structure of the electronic darts 』, the pressure contact movable dry block (16) is mounted on the target body, and the induction coil (15) is further disposed on the circumference side of the movable target block (16), and the above structure is used to provide the fly recording dry simultaneously.

The line '(4)-magnetic money is recorded with a sound sensor, and the sound sensor is divided into electronic Wei connection. The county is still producing the correct scoring data under the electromagnetic interference. The other purpose of the present invention is to provide a sound for calculating the miscellaneous sound and electromagnetic integrated sensing micro-system, and the sound of the sound sensor should be recorded. (The preset frequency and volume can be taken), and the sound sensor and the scoring electronic circuit are connected to the thief, and the ball result is calculated together with the scoring result. The invention of the present invention is used for achieving the above purpose. Techniques, means and other functions are listed as follows. Preferred embodiments and detailed descriptions of the drawings are as follows. It is believed that the objects, features and other advantages of the present invention can be obtained from the in-depth and specific understanding; 1291359 - Tea Referring to the third and fourth figures, the system diagram and the embodiment of the present invention are shown in detail. The invention is described in detail below. The present invention comprises a dart target (2 〇) and a magnetic induction coil (3). ), scoring electronic circuit (40) and sound sensor (50)' and matching with the magnetic flying brocade (60) for the shooting and scoring operation; where: 'The recording is dry (2 0), There are several counting zones (2 1 ) for darts (6 〇) for darts; # The magnetic induction coil (30) is a magnetic sensing element placed on the dart target (20), and respectively corresponds to the dart (2 〇) each meter partition (21); § Hai score electronic circuit (40), mounted on the dart target (20), and a scoring electronic circuit (4Q) connecting each of the magnetic coils (3 q ), and receiving the magnetic induction signal transmitted by the magnetic induction coil (3 〇); the sound sensing H ( 5 Q ), the pair is placed on the side of the hiding (2 〇), and Connected to the scoring electronic circuit (40), and the sound signal is generated according to the predetermined frequency and volume of the design corresponding to the recording sound of the dart (60), and the scoring electronic circuit (4Q) is synchronously connected to the integrated magnetic induction coil. (3 Q ) The magnetic sensor signal and the sound sensor (5 〇) sound signal, when the two signals are simultaneously received, the sound sensor (5 〇) The sound signal of the single sound sensor (5 〇) is considered to be dry, and the magnetic signal of the single magnetic induction coil (3 〇) is not scored or counted, and the _ score electronic circuit (4 〇) is calculated. The output is backward and outward (the way of turning out the signal and displaying the signal is customary, 8 10 '1291359 is not repeated here); the above is the structure, technology and structure of the sound and electromagnetic integrated induction darts system of the present invention. Detailed description of the relevant location. [Embodiment] In order to clearly explain the implementation of the present invention, the following is a schematic diagram of the sound and electromagnetic integrated induction dart system of the third embodiment of the present invention and the implementation of the fourth figure: The present invention is directed to the magnetic induction coil (3) 〇) and the sound induction is (5 0) the magnetic recording of the sensor (6 〇), and the magnetic sensor number of the integrated recording (6 〇) and the dart sound are recorded and scored. When normal darts: A magnetic dart (6 〇) dart is inserted into one of the dart targets (2 )), and the corresponding partition (2 i ) is set on ( 2 0 ) _ The induction coil (3 Q ) generates a magnetic wire cutting effect, and the magnetic induction coil (3 Q ) generates a corresponding lining (6 q ) axis _ sense signal; at the same time 'the lin (6 Q ) inserts the Wei (2 Q ) It will produce: the fixed frequency, the volume of the sound _ sound (similar, 朵 鳞 scale sound), and the sound sensor (5 〇) arranged on the side of the target (20) will induce the sound of the dart according to the design. Inductive signal; I29l359 Next, the scoring electronic circuit (40) synchronously integrates the magnetic induction signal of the magnetic induction coil (3 〇) with the acoustic signal of the sound sensor (50), and obtains both signals to score It is valid and is output after calculation. Abnormal situation: When someone picks up the mobile phone or has electromagnetic equipment in the competition, although the magnetic induction coil (30) on the recording (20) also produces the magnetic wire cutting effect, And the magnetic induction coil (30) generates the magnetic sensation corresponding to the dart (6 〇) However, the scoring electronic circuit (4 〇) cannot synchronously integrate the magnetic signal and the sound signal, so the scoring electronic circuit (4 〇) will not count the magnetic signal of the single magnetic induction coil (30) into the effective meter. The score is not counted as empty and is not counted, and is output after counting the nose. When recording the air dry: When the user of the present invention shoots an empty target, a magnetic dart (6 〇) dart is inserted into the dart target (2 〇) The non-counting partition (including the surrounding area), since the dart target (2 〇) is not counted and the magnetic induction coil (30) generates magnetic line cutting, there is no magnetic signal when the dart (60) is empty. However, when scoring, the 十口十刀包子电路 (4 〇) still cannot synthesize the integrated magnetic signal and the audible signal, 'only the sound signal of the single-sound sensor (5 〇) will be judged whether Wei target (the technology that can distinguish the darts is already used, not repeated here), 8:1291359 and the score electronic circuit (4 Ο) calculates the number of empty targets. The invention can still produce correct under electromagnetic interference. Scoring data, and can use the tower sensor to set the sense The sound of the dart, and the empty target is also calculated by the scoring electronic circuit, therefore, the result of the present invention and the result of the scoring will be different from each other's full compliance with the current competition standard. ^ New Zealand must explain that The darts of the invention cooperate with the magnetic induction coil and the sound sensor to induce the lining, as to whether the darts have the magnetic force to operate the invention _, the magnetic dart implementation method is as in the front stage system, and the magnetic sensation can be utilized by the magnetic induction coil of the dart magnetic induction coil. The change obtaining signal (the various sensing technologies of the magnetic induction coil are conventional and will not be described herein); therefore, the darts of the present invention are not limited to magnetic forces, and generally non-magnetic darts can also be equipped with a magnetic induction coil to generate a scoring operation. • In summary, the innovative structural design of this case is equipped with a magnetic induction dart target equipped with a sound sensor, and the sound sensor is connected with the scoring electronic circuit, and the scoring electronic circuit is simultaneously receiving the sound sensing and the magnetic sensing. Scoring, the foregoing system can still generate correct scoring data under electromagnetic interference, and can inductively calculate air-drying; therefore, the "industrial availability" of the present invention should be undoubted, in addition, in this case The feature technology revealed by the example has not been seen in the publications before the application, nor has it been used publicly. It not only has the fact that the effect of the above mentioned 1291359 is enhanced, but also has an additional effect that cannot be neglected. Therefore, the novelty of the present invention Sexuality and "progressiveness" have been in compliance with patent laws and regulations, and applications for invention patents have been filed in accordance with the law, and pray for review and early grant of patents. 1291359 [Simple description of the diagram] The first diagram is the first schematic diagram.
