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.

1 . An XO board for cross-and-circle game, comprising: 
 a bottom plate having an amplifier and a power switch provided at predetermined positions thereon;    a circuit board being provided on an upper side with nine orderly arranged actuating switches;    a top plate being provided at one side with a battery compartment for accommodating batteries to supply power needed by said actuating switches to operate normally; and    a plurality of first and second types of chess pieces, each of which is provided on a bottom surface with a metal sheet.    
   
   
       2 . The XO board as claimed in  claim 1 , wherein said circuit board is provided at a lower side with related electronic elements and an IC sound effect component.  
   
   
       3 . The XO board as claimed in  claim 1 , wherein each of said actuating switches provided on said circuit board includes a pair of magnets, two pairs of dams, a pair of springs, and a pair of metal spring leaves.  
   
   
       4 . The XO board as claimed in  claim 3 , wherein said pair of springs in each said actuating switch are arranged to point toward two opposite directions, two outer ends of said pair of springs being fixed to the lower side of said circuit board and connected to one of two electrodes of said IC sound effect component, and two inner ends of said pair of springs being two loops separately put around said pair of magnets.  
   
   
       5 . The XO board as claimed in  claim 3 , wherein said metal spring leaves in each said actuating switch are n-shaped members having two legs, each of said metal spring leaves straddling one of said two springs with said two legs downward fixed to the lower side of said circuit board and connected to the other electrode of said IC sound effect component.  
   
   
       6 . The XO board as claimed in  claim 1 , wherein said circuit board is provided at a position in the vicinity of each said actuating switch with a light-emitting-diode (LED) indicating lamp.  
   
   
       7 . The XO board as claimed in  claim 6 , wherein said LED indicating lamps have pins provided at a lower end thereof to electrically connect to said IC sound effect component.  
   
   
       8 . The XO board as claimed in  claim 1 , wherein said top plate is provided on an upper surface with a plurality of flat-bottomed round recesses corresponding to said actuating switches on the top of said circuit board, and each of said round recesses having a size close to an area covered by each said actuating switch.  
   
   
       9 . The XO board as claimed in  claim 8 , wherein said top plate is assembled to the top of said circuit board with one of said two magnets in each said actuating switch generally aligned with a central area of a corresponding one of said round recesses, and the other said magnet generally aligned with a peripheral area of said corresponding round recess.  
   
   
       10 . The XO board as claimed in  claim 1 , wherein said metal sheet mounted on the bottom surface of each said first type of chess piece is located at a central area of said bottom surface.  
   
   
       11 . The XO board as claimed in  claim 1 , wherein said metal sheet mounted on the bottom surface of each said second type of chess piece is located at a peripheral area of said bottom surface.  
   
   
       12 . The XO board as claimed in  claim 10 , wherein said metal sheet on said bottom central area of each said first type of chess piece is aligned with a first one of said two magnets in each said actuating switch on the top of said circuit board when said first type of chess piece is positioned in one said round recess on said top plate.  
   
   
       13 . The XO board as claimed in  claim 11 , wherein said metal sheet on said peripheral area of each said second type of chess piece is aligned with a second one of said two magnets in each said actuating switch on the top of said circuit board when said second type of chess piece is positioned in one said round recess on said top plate.
