Abstract
The utility model discloses a kind of child's pinyin learning apparatus, comprise light emitting diode, student side button, student side keyboard, with door chip, teacher side button, teacher side keyboard and external conduction line.The beneficial effects of the utility model are that product is novel unique, and phonetic teaching aid form different from the past, can improve students' participation interest, increases classroom interactions's property, makes the relation of student and teacher more harmonious.
Description
technical field
The utility model relates to field of Educational Technology, especially relates to preschool education field.
Background technology
In teaching, especially the cognitive aspect of child to abstract things is also weaker for primary grades pupil, and concentrated force during study also has much room for improvement; Therefore, in child's phonetic teaching, teaching aid plays very important effect, and it can make abstract knowledge image, specialize, thus makes it improve cognitive ability to knowledge, inspires the interest for awarded knowledge simultaneously, improves the quality of teaching; Also teachers and students can be made to produce interaction, cultivate the solidarity and cooperation ability of teachers and students.Existing phonetic teaching apparatus is divided into teaching aid laying rack, pinyin learning teaching aid, Chinese character learning teaching aid, a few class of line tool.For the study of phonetic, existing teaching aid mostly is rotating disc type combined appliance for teaching, Slot Machine formula combined appliance for teaching or be drawing and pulling type combined appliance for teaching; Form is comparatively old, weakens to some extent the attractive force of the students of the junior years, interactively also has much room for improvement.
Utility model content
In order to overcome the problems referred to above, the utility model provides a kind of instrument utilizing AND circuit control technology to carry out phonetic test, the technical scheme adopted is as follows: a kind of child's pinyin learning apparatus, it is characterized in that, comprise light emitting diode, student side button, student side keyboard, with door chip, teacher side button, teacher side keyboard and external conduction line; Described student side keyboard is provided with described student side button, described student side button is respectively equipped with different phonetic alphabet; Described teacher side keyboard is provided with described teacher side button, described teacher side button is respectively equipped with different phonetic alphabet; Described student side button is connected with an input terminal of door chip with described respectively, described teacher side button is connected with another input terminal of door chip with described respectively, connect same described with on door chip described in student side button identical with the phonetic alphabet of described teacher side button; Described is connected with described light emitting diode respectively with the output terminal of door chip; Described light emitting diode is installed on described student side keyboard; Described student side button is connected with power supply, and whole circuit connecting wire and on-chip power are in the housing of described student side keyboard; Described with door chip, its model is 74LS08; Described student side keyboard is connected with described teacher side keyboard by external conduction line.
The utility model has the following advantages: product is novel unique, and classroom interactions's property is strong, makes the relation of student and teacher more harmonious, effectively improves learning interest and the notice of child.

In figure: 1 light emitting diode, 2 student side buttons, 3 student side keyboards, 4 with door chip, 5 teacher side keyboards, 6 external conduction lines.
Embodiment
For the technical characterstic of this programme can be clearly demonstrated, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1, Figure 2 and Figure 3, a kind of child's pinyin learning apparatus, is characterized in that, comprise light emitting diode 1, student side button 2, student side keyboard 3, with door chip 4, teacher side keyboard 5, external conduction line 6 and teacher side button; Described student side keyboard 3 is provided with described student side button 2, described student side button 2 is respectively equipped with different phonetic alphabet; Described teacher side keyboard 5 is provided with described teacher side button, described teacher side button is respectively equipped with different phonetic alphabet; Described student side button 2 is connected with an input terminal of door chip 4 with described respectively, described teacher side button is connected with another input terminal of door chip 4 with described respectively, connects same described identical with the phonetic alphabet of described teacher side button with the student side button 2 described on door chip 4; Described is connected with described light emitting diode 1 respectively with the output terminal of door chip 4; Described light emitting diode 1 is installed on described student side keyboard 3; Described student side button 2 is connected with power supply, and whole circuit connecting wire and on-chip power are in the housing of described student side keyboard 3; Described with door chip 4, its model is 74LS08; Described student side keyboard 3 is connected with described teacher side keyboard 5 by external conduction line 6.
When often serving as a teacher test, teacher tells the pronunciation of the phonetic that student will input, simultaneously teacher correctly inputs on teacher side keyboard 5, and student inputs at student side keyboard 3, namely serves as a teacher end button when pressing, press phonetic alphabet incoming line connect, when student side keyboard 3 also presses same letter, another incoming line of these phonetic alphabet is also connected, and now two circuits are connected simultaneously, connect with door chip control circuit, it is luminous that output signal controls light emitting diode 1; When student and teacher press the button of identical phonetic alphabet, light emitting diode 1 just can be luminous; If mistake, then light emitting diode 1 is not luminous, understands student's input to mistake with this; The button pressed is pressed again, reset of can upspringing, and each button is a snap switch, therefore, and all can hand-reset for situation about pushing the wrong and restart.
