Description

[Detailed description of the invention] This invention relates to a jigsaw puzzle that produces a sound, such as a melody or the like, which is made to flow when cut-out partial pictures are inserted into the jigsaw puzzle mount.

A jigsaw puzzle is a toy that is enjoyed by fitting die-cut partial pictures onto a mount to complete the whole picture as quickly as possible, but with conventional jigsaw puzzles, only the visual pleasure was obtained. When the number of die-cut partial pictures increases, at the beginning of the game it is difficult to tell whether the parts have been fitted into the corresponding parts of the mount, which can sometimes be frustrating for those playing the game. , I sometimes quit the game midway through because it's so difficult.

The purpose of this invention is to provide a sound-producing jigsaw puzzle that adds auditory enjoyment that cannot be obtained with conventional jigsaw puzzles, makes the game even more relaxing, and provides three-dimensional visual and auditory enjoyment. do.

This idea will be explained below.

This invention relates to a jigsaw puzzle that generates sound, and includes a non-contact switch means that turns on or off to output a step signal when each partial picture of the jigsaw puzzle is correctly fitted, a differentiation circuit that differentiates the step signal, and a sound generating circuit having a timer operated by a differential signal differentiated by the differentiating circuit and generating sound according to the output of the timer; a speaker connected to the sound generating circuit; A sound generating device consisting of a sound generating circuit and a battery that supplies power to a speaker is embedded in a jigsaw puzzle mount, and each partial picture of the jigsaw puzzle is fitted into the mount, so that each of the partial pictures is correctly fitted. When the switch means is turned on or off, a sound is generated each time the switch means is turned on or off.

Figure 1 shows the schematic structure of a jigsaw puzzle that is an embodiment of this invention.The surface of jigsaw puzzle 1 has a picture (in this example, a picture of Mt. Fuji and clouds).
is drawn, and this picture is die-cut into several partial pictures 2. The number of die-cut sheets is determined according to the difficulty level, and a reed switch 4 as a switching means is embedded in a portion of the mount 3 at a position corresponding to each of the plurality of die-cut partial pictures 2. , permanent magnets 4A are embedded in the corresponding positions of partial picture 2, respectively, as shown in FIG. That is, since the magnets 4A are embedded in each of the partial pictures 2, and the reed switches 4 facing each other are buried in the corresponding mounts 3, the partial pictures 2 are fitted in the correct position. When this occurs, the reed switch 4 is turned on. In addition, a small speaker 10 and a power switch 5 are provided on the upper surface of the mount 1 of the jigsaw puzzle, and the mount 1 is further equipped with a sound generating circuit 14 made of an IC element, a battery 11, a reed switch 4A, and other components to reduce the size. A sound generating device is buried.

FIG. 3 is a circuit configuration diagram showing an example of a sound generating device, and the reed switches 4 buried corresponding to the partial pictures 2 are connected to the array via a resistor, and one end P1 of the parallel connection is connected to the array through a resistor. Power switch 5
is connected to the battery 11 via the other end of the parallel connection P
2 is connected to the buffer amplifier 16. The step signal SP from the buffer amplifier 16 obtained by turning on the reed switch 4 is input to the differentiating circuit 12 and differentiated, and the differentiated signal DS is
For example, the rising edge of is inputted to the timer 13 as a trigger signal. The timer 13 outputs an activation signal TS for a predetermined period of time (for example, 3 seconds), this activation signal TS is input to the sound generation circuit 14, and the sound signal SS output from the sound generation circuit 14 is sent to the speaker 10 via the amplifier 15. It is beginning to be given to

In the above configuration, when starting a jigsaw puzzle, all partial pictures 2 are removed from the mount 1, and then by pressing the power switch 5, the small speaker 10 becomes ready to sound at any time. , power is supplied to one end P1 of the parallel connection. At this time, all reed switches 4 are off. Then, when the removed partial picture 2 is inserted into the appropriate position on the mount 1, the reed switch 4 is turned on by the magnetism of the permanent magnet 4A embedded in the partial picture 2, and the power from the battery 11 is supplied stepwise. is supplied to the buffer amplifier 16, and the step signal SP from the buffer amplifier 16 is supplied to the differentiating circuit 1.
By being differentiated by 2 and input to the timer 13, the timer 13 outputs the operation signal TS,
When the sound signal SS is output from the sound generation circuit 14 for a predetermined period of time, the speaker 10 generates a sound such as a melody, and the person playing the puzzle receives the partial picture 2.
It informs you that it has been fitted in the correct position. Note that it is better that the sound such as a melody emitted at this time is not too long, and the timer 13 may be set to several seconds in consideration of the action of fitting the next partial picture. Note that if the partial picture 2 cannot be fitted to the proper position on the mount 3, the reed switch 4 will not be turned on, so the step signal SP will not be generated, and the speaker 10 will not be generated.
There is no sound from either.

In this way, if you insert the partial pictures 2 in order while listening to the sound from the speaker 10, if you place a partial picture in the wrong position, you will immediately know the mistake, and you will be able to play puzzles quickly. .

In addition, in the above, the sound is emitted for each partial picture, but if you connect each contact of the reed switch in series, the sound will be emitted when all the partial pictures are inserted and the picture is completed. Become. In addition, in the above description, the reed switch and the permanent magnet are used to identify whether or not the partial picture fits properly, but a micro switch using a spring can also be constructed in the same way, and a magnetic material is buried in the partial picture. A proximity switch for detecting this may be embedded in the mount.

As mentioned above, according to the jigsaw puzzle of this invention, not only visual but also auditory enjoyment is added.Moreover, if there are many pieces of paper, the difficulty of the puzzle increases, but if each piece is fitted in the correct position. Since it emits a sound, it has the advantage of giving the player persistence and at the same time making them forget the difficulty of the puzzle. Furthermore, the level of satisfaction when the picture is completed when all the pages fit together is further enhanced by the pleasant melody playing.
