Description
Technical field
The utility model relates to a kind of child and learns appurtenance, refers in particular to a kind of quantitative relation that the graphic presentation mathematical operation is arranged, and has the multilingual computer mental arithmetic exercising machine of foreign language learning function concurrently.
Background technology
The mental arithmetic exercising machine is to help the child to temper a kind of instrument of mathematical operation logical thinking ability.Existing mental arithmetic exercising machine, all be aphonic (the mental arithmetic exercising machine shown in patent No. ZL95202119.6), and the quantitative relation that does not all have the graphic presentation mathematical operation, can not be when the mental arithmetic exercise, switch different language, reach the purpose that learns a language, visual in image inadequately, and be not suitable for child's thinking characteristic, also can't present more function.
The utility model content
The purpose of this utility model is, provides a kind of and has available graphic presentation and go out the mathematical operation relational expression, has the multilingual computer mental arithmetic exercising machine of foreign language learning function concurrently.
The utility model is achieved through the following technical solutions: a kind of multilingual computer mental arithmetic exercising machine is provided, comprise protecgulum, bonnet and be arranged on circuit board assemblies, battery cover on the bonnet, described protecgulum is provided with a plurality of sound transmission aperture, be provided with sounding parts facing to sound transmission aperture at the protecgulum back side, described sounding parts are electrically connected with circuit board assemblies, be provided with the LCD LCDs on protecgulum, described LCD LCDs is provided with the matrix icon of the quantitative relation of expression mathematical operation; Expression Chinese, English, Japanese, French, Russian, the icon of speech selection such as Spanish; The expression addition, subtraction, multiplication, division, the icon that the hybrid operation scheduling algorithm is selected.Described LCD LCDs is electrically connected with circuit board assemblies, on protecgulum, be provided with power switch button, the algorithm selector button, the exercise button, the examination button, speech selection button and numeral input button, described power switch button, the algorithm selector button, the exercise button, the examination button, speech selection button and numeral input button are electrically connected with circuit board assemblies, circuit board assemblies is connected with power supply, circuit board assemblies is provided with the micro computer voice IC chip that is used to control demonstration of LCD LCDs and sounding parts sounding, store Chinese and English mathematics mental arithmetic exerciser in the micro computer voice IC chip, also can include more kinds of language such as Japanese, French, Russian, Spanish etc.
The utlity model has following advantage: the utility model can switch the pronunciation languages by the speech selection button, make it not only have the function of Chinese pronunciations mental arithmetic exercise, can have English or other state's language simultaneously (as Japanese, French, Russian, Spanish etc.) function of pronouncing to do a sum orally and practising makes the child in the learning mathematics computing, can learn corresponding foreign language knowledge again.More than mode by student and computer human-computer interaction, make study become more interesting, and by the quantitative relation of graphic presentation mathematical computations, visual in image, meet child's thinking characteristic, impression is more deep, results of learning are better.
