Detailed Description

The language learning device can be used for learning English, french, german and other letter type languages and Chinese pinyin. Fig. 1 is a block diagram of a language learning apparatus according to an embodiment of the present invention. As shown in fig. 1, the apparatus includes a plurality of magnetic letter blocks, a learning platform, and a language processing system.

The surface of the letter block is printed with letters. In English, for example, there should be at least 26 letter blocks on which 26 letters "a, b, c, d, \ 8230; \8230;, z" are printed, respectively. But a large number of words contain a plurality of identical letters, and therefore a plurality of letter blocks are preferably provided for each letter. The letter blocks can be made into various shapes like building blocks. And an NFC label for identifying the identity of the letter block is arranged on the letter block. And receiving a signal transmitted by the NFC label of the letter block by utilizing the NFC reader and reading the ID number of the letter block. The NFC reader may be disposed on a learning platform.

A plurality of lattices for placing letter blocks and a sensing circuit for sensing the placing positions of the letter blocks are printed on the surface of the learning platform. The induction circuit comprises a signal input end, a signal output end, an upper circuit layer, an insulating layer, a lower circuit layer and an iron bottom plate which is subjected to insulating treatment, wherein the upper circuit layer, the insulating layer and the lower circuit layer are arranged from top to bottom in a layered mode. The iron bottom plate can be treated by painting and porcelain baking. The upper and lower circuit layers are printed with conductive ink. The upper circuit layer and the lower circuit layer include upper contacts and lower contacts facing the grid, respectively. The insulating layer has holes at the lattices. The signal input end is connected with the upper layer contact, and the signal output end is connected with the lower layer contact. When the magnetic letter block is placed on the grid, under the action of magnetic force between the letter block and the iron plate, the upper layer contact and the lower layer contact at the grid cross the holes to be in contact with each other so as to connect the signal input end with the signal output end; after the letter block is removed, the contacts are disconnected. Wherein the upper contacts and the lower contacts at different lattices form different signal paths with the signal input terminal and the signal output terminal. It should be noted that the two contacts at the grid can also be closed by pressing, i.e. it is not necessary that the letter blocks have magnetic material and the bottom plate is ferrous. This saves manufacturing costs and also makes the base plate flexible.

In one embodiment, as shown in fig. 2, the signal input terminal is connected to the positive power supply terminal as a common terminal, e.g., +3.3V; a contact of the lower circuit layer is connected with an IO port of the language processing system processor through a signal output end, and the processor can judge through the IO port which lattice contact the signal of the signal input end is transmitted through.

The language processing system acquires the ID number of the letter block and the placement position of the letter block under the ID number on the learning platform by using the NFC reader and the induction circuit, so that a letter group (word) consisting of the letter blocks is obtained.

And when the language processing system judges that the letter group is a correct word and the placing sequence of the letter blocks forming the letter group is correct, the player is used for playing the letter group. When the language processing system judges that the letter group is a correct word but the placing sequence of the letter blocks forming the letter group is wrong, the language processing system sends out prompt information by using the player. When the language processing system judges that the letter group is an error word, the player is also used for sending out prompt information. The player may be a voice player configured by a learning platform or on a terminal device. The terminal equipment can be a mobile phone, a computer and the like.

Prompt patterns such as Chinese characters, animals, fruits, vegetables, characters and the like can be printed on the learning platform, and lattices for placing letter blocks when spelling words are arranged below the patterns. With reference to fig. 1, taking english word "year" as an example, on the learning platform, the chinese characters "year" are printed, and four lattices are arranged below "year", so that spelling is correct only when the user places letter blocks "y", "e", "a" and "r" on the four lattices 1, 2, 3 and 4 in sequence. The user can only correctly spell the panda pattern by placing the letter blocks "p", "a", "n", "d", and "a" in the order of five

boxes

5, 6, 7, 8, and 9 by setting five boxes below the panda pattern.

The learning platform can be provided with a display screen, and patterns of Chinese characters, animals, fruits, vegetables, characters and the like are displayed through the display screen. The learning platform can be also provided with communication ports such as Bluetooth and USB. The patterns displayed on the display screen can be replaced by devices such as a mobile phone, a computer, a U disk, a mobile hard disk and the like. The child places letter blocks in the grid directly below the display screen to spell the words corresponding to the pattern.

It should be noted that the pattern and the display screen are not essential. The learning platform can only be provided with a plurality of lattices for placing letter blocks. The words to be spelled are transmitted to the learning platform through devices such as a mobile phone, a computer, a U disk, a mobile hard disk and the like, the words are spelled by a player on the mobile phone, the computer or the learning platform, and the letter blocks forming the words are sequentially placed in the corresponding lattices by children in a building block playing mode.

The spelling of the corresponding words is completed through the ordered arrangement and combination among the letter blocks, and the learning language habit of spelling and reading according to the letters of children is met. The letter blocks are made into the pattern of building blocks, so that the interest of children can be caught. The building blocks form words to train the logic thinking and the operation ability of the children, which is beneficial to quickly and accurately memorizing the words and deepening the long-term memory of the words.

The upper circuit layer and the lower circuit layer are printed by conductive ink materials, the manufacturing is easy, the cost is low, the conductive ink has good printability, and printing stocks are flexible and diverse, so that the learning platform can be made into a flexible character learning wall map. The upper circuit layer and the lower circuit layer are located inside the learning platform, so that the conductive ink circuit is hidden, and the appearance of the learning platform is not affected. The on-off of the upper contact and the lower contact at the grid is controlled by the magnetic force between the magnetic letter block and the iron plate, the mode is simple, and the learning platform does not need to be improved in a complex way. By adopting the NFC technology, the problem of mutual interference when the number of letter blocks is large can be solved.
