Description
The utility model is a kind ofly to collect that study and mistake are happy be the brick pattern audio-visual education programme toy of one, and suit child or pupil add, subtract, the training of the multiple calculating skill of multiplication and division.
Retrieval, the existing technological document that closes of examination, original applying number is 89217315.7 utility model " child intelligence learning machine ", though the function of preschool education is arranged, but, since in the number combination, dongle configuration, and the aspects such as reliability of signal identification circuit, power supply, appearance design, work exist the improved place of a lot of needs, to make this technology rest on the laboratory sample stage always, can not form commodity production and put goods on the market.
Purpose of the present invention is to implement a kind of new and original slotting sign indicating number rotation brick pattern child intelligence learning device that improved, and this learning machine is simple in structure, is easy to make suitability for industrialized production.
The utility model is made up of digital building blocks and computing acousto-optic circuit that shell, work calculate usefulness.Socket, button, pilot lamp, tap switch, colored spin etc. are housed on the shell, digital building blocks are rectangular parallelepiped, plug is housed below, end face indicates numeral, the side indicates formula, and the computing sound light control circuit is by resistor voltage divider circuit, threshold voltage comparator circuit, form with door switch circuit, sound and light show circuit, game circuit five parts.Use this machine, can carry out the computing of three kinds of difficulty (plus-minus, Lian Jialian subtracts, addition subtraction multiplication and division mixes) and multiple mode.
During use, tap switch is dialled on learn position, chosen digital building blocks, insert and " a ± b=c " respectively, in the corresponding socket, and form formula.Resistance is by the voltage division signal that is connected to form of socket in this moment building blocks, and three foot controls under unlike signs are sent signal into the threshold voltage comparator circuit of being made up of two integrated circuit, send into and door switch circuit after relatively, and then the guide sound optical circuit.If computing is correct, signal is sent in the integrated music circuit through AND circuit, and a first graceful melody gathers out.Light glittering (being made up of the reflective mirror bucket) in shielding simultaneously is to show bonus.If operation mistake, AND circuit is ended, and no music is sent, and has only green light to show, continues to select to show.Rotate or the displacement building blocks, can form new formula.If tap switch is dialled on game position, press left side button, colored roll rotational, form dreamlike pattern, press the right button, can send eight kinds of analog audios.
The utility model compared with prior art has significant progress and significant good effect.
(1) in the utility model, digital building blocks simultaneously are equipped with plug, and five faces indicate numeral and formula, and can replace in socket and rotate.So building blocks are few, the selected topic is many, 23 blocks of building blocks can be formed the computing of the multiple difficulty of 20,000 multiple tracks topic.(calculating with permutation and combination) expanded learning content greatly.
And in the prior art, digital plate single face coding, and can not rotate so can only form the simple plus and minus calculation of 200 problems.
(2) in the utility model, a conventional, electric-resistance is housed in the digital building blocks, its trueness error ± 1%, cost is low, is easy to choose.
And in the prior art, two substitutional resistances are housed in the digital plate, and cost is too high, and precision is too high, and its trueness error is ± 1%.
(3) in the utility model, digital building blocks connector is 2 contact general parts, selects φ 3.5 round end edge connectoies in this example for use, and material is easy to get, and cost is low.
And in the prior art, the digital interpolation board connector is 4 unusual parts of contact, complex structure, technology harshness.
(4) in the utility model, signal input discriminator circuit has adopted resistor voltage divider circuit, the threshold voltage comparator circuit, and circuit is simple and reliable and cost is lower.
And in the prior art, signal input discriminator circuit has adopted dual power supply, double bridge, double operational circuit, the circuit complexity, and cost is higher.
(5) in the utility model, adopted the single power supply mode, supply voltage is that 4.5V is composed in series by one group of three joint No.5 cell, one side supplying cell negligible amounts, on the other hand, because the lower limit operating voltage of LM324 integrated circuit is 2.8V, when so single battery voltage drops to 1V, circuit still can operate as normal, has so not only prolonged the serviceable life of battery, and guaranteed to use the old times, the reliability of complete machine work when battery.
And available technology adopting the dual power supply mode, by 2 groups independently the 3V power supply form, more with number of batteries on the one hand, on the other hand, when single battery voltage drops to 1.4V when following, circuit working is unusual, occurs the malfunctioning phenomenon of computing function easily.
(6) the utility model has increased game circuit, is made up of electronic spin, eight kinds of analog audios and reflective mirror screen, has strengthened the attractive force to children greatly.
In the prior art, do not have game function is arranged, so recreational, interesting relatively poor.
(7) abstract modeling, new and original of modernist has been adopted in the utility model appearance design, has certain technology to be worth.
And in the prior art, appearance design is traditional piano-style moulding, lacks anger, and the consumer is lacked attractive force.
Accompanying drawing 2 is digital building blocks of the present invention and socket synoptic diagram, and wherein (c) is digital building blocks structural map, (d) is digital building blocks plugs and sockets structural drawing.
Accompanying drawing 3 is external form figure of the present invention.
With reference to accompanying drawing 3, the child intelligence learning machine is installed in the pilot lamp (11) on the shell and is shielded interior flashlamp (4) by shell (1), and loudspeaker (3) indicates digital digital building blocks (2), and socket (5) and operation token (7) are formed.The tap switch (6) of study and recreation usefulness is set, spin button (8), octave button (9) in the position, front lower place of shell (1).The shell top is provided with colored spin (10).
