  The existing method is very good as an experimental method for learning the principle of electronic circuits and developing electronic circuits, but for young people, beginners or girls, the principle of electronic circuits and the difficulty of electronic circuit diagrams, It is difficult to learn electronic circuits, such as difficulty in handling parts. In addition, since the electronic circuit is incorrectly assembled and cannot be completed, it may be reluctant to assemble the electronic circuit. Furthermore, even with easy-to-handle electronic component blocks, the assembled electronic circuit finished product often lacks designability in order to strengthen the color of scientific teaching materials or scientific toys, which may impair interest in the electronic circuit. Therefore, in order to have a keen interest for beginners, in the first stage, anyone can assemble without making any mistakes even if there is no explanation or circuit diagram, and it is possible to replace electronic circuit parts as necessary for learning and complete Later, you need something with excellent design that you can decorate as an interior.

  In the present invention, a small cube block, which is called a cube, with built-in electronic parts, n × n × n (where n is a natural number of 2 or more) is connected at a connecting portion to form a large cube. The electronic circuit is completed by connecting this large cube to the power plate, and the interior can be placed indoors.

Cubes can be attached to and detached from each other, and for connection, there is a mechanical connection between the connection projection protruding from the center of one cube surface and the connection hole at the center of the other cube surface, and it exists on the cube surface around these connections Electrical connection is made by metal connection pins or metal connection holes. The electrical connection ends are arranged on the cube surface so that there is only one set of surfaces that can be joined. Therefore, accidental coupling to other cubes is avoided, and as a three-dimensional jigsaw puzzle, n ³ cubes are combined, a large cube is assembled, and then coupled to the power plate to complete the electronic circuit. Can do. Thereby, even if there is no explanation and a circuit diagram, anyone can assemble an electronic circuit without making a mistake, and the above problem can be solved.

  The cube has an electronic component built in a transparent or colored transparent resin cubic container, and terminals of the electronic component are wired to an electrical connection end inside the cube. Therefore, the electronic components in the cube and their wiring can be seen from the outside, and the actual form of the electronic components can be known and handled easily, not the drawings or symbols. Further, the completed large cube gives a crystal visual sense because of the transparent resin, and can solve the above-mentioned problems as a value-added device as an interior interior together with the power supply plate.

  The bottom surface, which is the connecting surface with the large cube power plate, is constructed only from the connection pins at the electrical connection end, and one of the connection pins is thicker than the other connection pins, and the connection of the power plate One of the holes is correspondingly thickened. As a result, since there is only one way of connecting the large cube and the power supply plate, they are not erroneously connected.

  The electronic circuit can be assumed to be a sensor circuit, a high-frequency circuit, etc., but a light-emitting diode is built into one or more of the cubes to add an optical effect, and the power supply plate that supplies current includes a speaker in addition to the power supply A built-in sound effect is added to visualize and sound the response of external information so that changes in information can be perceived as sensations. When a cube with a built-in resistor or capacitor is exchanged, the change can be perceived as a sensation, which is an elementary learning of electronic circuits. Large cubes that produce a crystallized visual sensation light up the whole light in the dark by the light emission of the light-emitting diodes, enhance the crystallized visual sensation, promote beginners' interest in electronic circuits, and solve the above problems It can be done.

  The present invention is suitable for school children, beginners of electronic circuit work, and women who are not good at electronic circuits and tend to avoid them. It is characterized by being able to. After the completion of the present invention, by appealing to the senses by the output of light or sound, it is possible to have a strong interest in electronic circuits, which is suitable for the introduction of electronic circuit learning. Furthermore, this device, which is made of transparent cubes, has a design like a crystal and can be decorated indoors as an interior, and the entire device emits light by the light emitting diodes in an indoor dark place. Excellent in properties. Therefore, since it can be easily obtained by being placed in the room at any time and can be repeatedly disassembled and assembled, the electronic circuit can also be interested by this action. For beginners who want to develop and learn, prepare a cube of compatible resistors and capacitors, and change the circuit constants to understand the role of resistors and capacitors in electronic circuits. A rudimentary learning program can be organized. In addition, the built-in optical sensor circuit can learn about the concept of spectroscopy using a prism and infrared rays and ultraviolet rays other than visible light. Furthermore, by using the circuit of the embodiment of the present invention that converts light into sound using an infrared remote controller, it is also possible to create a melody, collect several devices, perform an ensemble, and adjust the light and sound pageant. The effects of adding design to this device can be expected. Using the brain, moving your hands, and stimulating the sense of light and sound will help prevent the elderly from blurring. Thus, the present invention not only plays an auxiliary role in the introduction of electronic circuit learning but also has an integrated effect and is excellent in practicality.

  In the present invention, small cube-shaped blocks called cubes (1) made of transparent plastic or acrylic material (FIG. 1 (a)) are connected to projections (2), connection holes (3) and connection pins. (4) and the connecting hole (5) are combined to form a large cube (7) (FIG. 2). The bottom surface of this large cube has a connection pin (15), and the device of the present invention is completed by connecting to the power supply plate (8) which is a power supply section (FIG. 1 (b)). As shown in the perspective sectional view (the left figure in FIG. 1A), the cube has an electronic component (6) built in, and an electronic circuit is completed by connecting a large cube assembled by joining the cube and the power supply plate. (FIG. 1 (b)).

  The connection convex part (2) or the connection hole (3) on the cube surface is located at the center of the surface (FIG. 1 (a)). The connection convex part (2) is made of the same material as the cube and becomes a cylindrical convex part. Its diameter is, for example, about one-fourth of the length of one side of the cube, and the height is slightly less than the thickness of the cube surface. A cut (13) is made in the convex portion along the diameter of the circle. The thickness of the connection hole (3) is set to a size suitable for the connection protrusion (2) to hold without a gap. The connection projections (2) and the connection holes (3) are not necessarily present on all surfaces of the cube, and do not exist on the surface that contacts the surface of the assembled large cube.

  In addition to the connection protrusion (2) or the connection hole (3), there are always two connection pins (4) or two connection holes (5) for electrical connection on the surface of the cube. Connect the cubes by placing the connection pins on the opposite faces (11) and the connection holes on the other face (12) of the two cubes shown in Fig. 1 (a) so that they are in the mirror image of each other. Let However, the combination surfaces that can be combined are arranged differently so that only one set exists. As a result, a large cube can be completed as a three-dimensional jigsaw puzzle. Only one connection pin is provided on the surface of one cube connected to the power supply plate (15). FIG. 2 shows a large cube in which 3 × 3 × 3 (27) cubes are assembled as an embodiment, and there are nine connection pins from the surface connected to the power supply plate. . Of these connection pins, one is a thick connection pin (16), and correspondingly, one of the connection holes of the nine power supply plates of the embodiment is a thick connection hole (17). (Figure 3). As a result, there is only one set of coupling methods between the large cube and the power plate.

  The connection pin (4) and the connection hole (5) use a metal such as copper having good conductivity, and the metal rod to be the connection pin and the metal pipe to be the connection hole protrude inside the cube, as required for wiring of the circuit configuration. Then, it is connected to the electronic component inside the cube (FIG. 1 (a)). The metal rod to be the connection pin and the metal pipe to be the connection hole are threaded (14), and the connection pin or the connection hole is screwed into the threaded hole of the cube surface and fixed to the cube. At this time, since the metal pipe to be the connection hole must be screwed from the inside of the cube, a cube with one side of the cube opened in advance (FIG. 4A), screwing and electronic parts After insertion, the lid (19) is put on to complete the cube (FIG. 4 (b)).

  As shown in FIG. 4A, the electronic component (6) is pre-soldered to the connection fitting (18), inserted into the cube, and the connection fitting is connected to the connection pin (4) inside the cube. It is inserted into a metal rod to be or a metal pipe to be a connection hole (5), and is electrically welded with a spot welder. After connecting the electronic components inside the cube, cover the lid (FIG. 4 (b)), and bond and fix with an adhesive to complete the cube. At this time, the cube surface without wiring is designed to be a lid as much as possible.
