Board for cross-and-circle game

Abstract

An XO board for cross-and-circle game is internally provided with a circuit board, on which an IC sound effect component is provided. Chess pieces used with the XO board are divided into two types, depending on the mounting position of a metal sheet at the bottom surface of the chess piece. When one chess piece is positioned on the XO board corresponding to an actuating switch electrically connected to the IC sound effect component, the metal sheet at the bottom surface of the chess piece would cause one of two magnets in the actuating switch to move upward and thereby actuates the IC sound effect component to produce a specific sound depending on the type of the chess piece.

Description

BACKGROUND OF THE INVENTION

With the prosperous and rapid developments in the industrial and commercial fields, people's living quality has been largely and constantly upgraded. As a result, most consumers have higher requirements for the products they intend to purchase. The products that meet consumers' requirements must economically provide good basic functions and have novel and fashionable appearances to increase their added value and make them more changeful and interesting when compared with other similar products.

It is therefore tried by the inventor to develop a unique sound-producing board for cross-and-circle game, or an XO board, with the above principle kept in mind, so that the XO board attracts more children.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide an XO board for cross (X)-and-circle (O) game that would produce a specific sound whenever a chess piece is positioned on a particular location on the board, and another specific sound, such as applause, whenever three chess pieces of the same type are formed into line on the XO board to win one game.

To achieve the above object, the XO board of the present invention is internally provided with a circuit board, on which an IC sound effect component is provided. Chess pieces used with the XO board are divided into two types, depending on the mounting position of a metal sheet at the bottom surface of the chess piece. When one chess piece is positioned on the XO board corresponding to an actuating switch electrically connected to the IC sound effect component, the metal sheet at the bottom surface of the chess piece would cause one of two magnets in the actuating switch to move upward and thereby actuates the IC sound effect component to produce a specific sound, such as cat's meow or dog's bark, depending on the type of the chess piece.

And, any three of the actuating switches that are located at one line may be electrically connected in parallel, whereby whenever three chess pieces of the same type having the metal sheet mounted to the same position on the bottom surface of the chess pieces are formed into line on the XO board, the sound of applause is emitted from the IC sound effect component as a notice of winning the game.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1 and 2 that are exploded and assembled perspective views, respectively, of a board for the cross-and-circle game according to the present invention. For the purpose of simplicity, the board for the cross-and-circle game is also referred to as the XO board throughout the specification, wherein “X” represents the mark “cross” and “O” the “circle”. As shown, the XO board of the present invention mainly includes a bottom plate 1, a circuit board 2 mounted on the bottom plate 1, a top plate 3 covering the circuit board 2 and the bottom plate 1, and a plurality of first and second types of chess pieces 4, 5.

The bottom plate 1 is provided on a top at predetermined positions with an amplifier 11 and a power switch 12.

The circuit board 2 is provided at a lower side with related electronic elements and an integrated circuit (IC) sound effect component, and at an upper side with nine (9) orderly arranged fixed positions, on each of which an actuating switch for actuating the IC sound effect component is provided.

As can be clearly seen from FIG. 3, the actuating switch includes a pair of magnets 21, 22, two pairs of dams 23, 24, a pair of springs 25, 26, and a pair of metal spring leaves 27, 28. The two springs 25, 26 are parallelly arranged to extend toward two opposite directions. Two outer ends of the two springs 25, 26 are fixed to the lower side of the circuit board 2 and connected to one of two electrodes of the IC sound effect component. Two inner ends of the two springs 25, 26 are two loops fixedly put around the two magnets 21, 22, respectively. The two metal spring leaves 27, 28 are generally n-shaped members having two legs and adapted to straddle the two springs 25, 26, respectively, with lower ends of the two legs fixed to the lower side of the circuit board 2 and connected to the other electrode of the IC sound effect component. When the spring 25 or 26 is in contact with the corresponding metal spring leaf 27, 28 to form a circuit loop, the IC sound effect component is actuated to produce a specific sound.

Moreover, a light-emitting-diode (LED) indicating lamp 6 is provided on the circuit board 2 close to each actuating switch. Pins provided at a lower end of the LED indicating lamp 6 are electrically connected to the IC sound effect component, so that the LED indicating lamp 6 flashes whenever the IC sound effect component is actuated to produce a specific sound.

The circuit board 2 includes an opening 29 provided at a position corresponding to the amplifier 11 on the bottom plate 1, so that the amplifier 11 is allowed to project from the opening 29 when the circuit board 2 is assembled to the top of the bottom plate 1.

The top plate 3 is provided at one side with a battery compartment 7, in which batteries 8 are mounted to supply power needed for the IC sound effect component and the LED indicating lamps 6 to operate normally. The top plate 3 is also provided on an upper surface with nine (9) flat-bottomed round recesses 31 at positions corresponding to the nine actuating switches on the top of the circuit board 2. Each of the nine round recesses 31 has a size close to an area covered by the actuating switch. When the top plate 1 is assembled to the top of the circuit board 2, the magnet 22 in the actuating switch is generally aligned with a central area of the round recess 31, and the other magnet 21 is generally aligned with a peripheral area of the round recess 31, as can be seen from FIGS. 4 and 5, respectively.

The first and the second type of chess pieces 4, 5 representing two opponents are so designed that they have a bottom surface slightly smaller than the round recess 31, so that the chess pieces 4, 5 may be positioned in the round recesses 31 in the process of playing the cross-and-circle game on the XO board of the present invention. The chess pieces 4, 5 are provided at their bottom surface with a metal sheet 41, 51, respectively. The metal sheet 41 is mounted at a bottom center of the chess piece 4, while the metal sheet 51 is mounted at a lower periphery of the chess piece 5, as shown in FIGS. 4 and 5, respectively. Therefore, when the first type of chess piece 4 is positioned in any one of the round recesses 31, the metal sheet 41 at the bottom center of the chess piece 4 would be in alignment with the magnet 22 in the corresponding actuating switch on the circuit board 2, as shown in FIG. 6, causing the magnet 22 to move upward and magnetically attract the metal sheet 41, as shown in FIG. 7. At this point, the spring 26 is pulled upward by the upward moved magnet 22 to finally touch the metal spring leaf 28 and thereby actuates the IC sound effect component below the circuit board 2 to produce a specific sound, such as cat's meow. And, when the second type of chess piece 5 is positioned in any one of the round recesses 31, the metal sheet 51 provided at the lower outer periphery of the chess piece 5 would be in alignment with the magnet 21 in the corresponding actuating switch on the circuit board 2, as shown in FIG. 8, causing the magnet 21 to move upward and magnetically attract the metal sheet 51, as shown in FIG. 9. At this point, the spring 25 is pulled upward by the upward moved magnet 21 to finally touch the metal spring leaf 27 and thereby actuates the IC sound effect component below the circuit board 2 to produce a specific sound, such as dog's bark.

Alternatively, it is possible to connect any three in-line actuating switches in parallel, so that whenever three chess pieces 4 or 5 are located to form into line, the IC sound effect component is caused to produce another kind of sound, such as applause, and the LED indicating lamps 6 at the vicinity of the corresponding actuating switches are caused to flash.

As having been mentioned above, when the top plate 3 is assembled to the top of the circuit board 2, each of the round recesses 31 has a central area aligned with the magnet 22 of the corresponding actuating switch, and a peripheral area aligned with the magnet 21 of the corresponding actuating switch. And since the metal sheets 41, 51 are respectively mounted to the bottom center and the lower periphery of the first and the second type of chess piece 4, 5, the positioning of the two types of chess pieces 4, 5 in the round recesses 31 on the XO board would not result in interference or confliction with each other. That is, the positioning of the first and the second type of chess piece 4, 5 in the round recess 31 would always cause the IC sound effect component to produce a specific sound representing the type of chess piece positioned in the round recess 31, such as the cat's meow or the dog's bark. And, whenever any three chess pieces of the same type 4 or 5 are formed into line, as shown in FIG. 10, the LED indicating lamps 6 in the vicinity of the corresponding actuating switches are caused to flash and the IC sound effect component is caused to produce the sound of applause.
