Abstract
The utility model discloses a Pinyin tone exercising device belonging to Chinese language teaching tool; the device comprises a substrate, a micro-controller, a motor drive circuit, and a white board arranged on the front side of the substrate; the white board is printed with four line grids; a tone rotary disc is arranged above the white board; one side of the tone rotary disc is provided with a pointer; the back side of the tone rotary disc is provided with a motor; a rotary shaft of the motor is connected with a central shaft of the tone rotary disc; the top of the substrate is also provided with a button. The Pinyin tone exercising device employs the rotary disc to generate different tones for students to practice pronunciations, has certain interests, and can improve learning interest of the students.
Description
Technical field
The utility model relates to a kind of spelling tone excise device, belongs to Chinese teaching aid.
Background technology
Concerning begining to learn the student of phonetic, the pronunciation of tone has certain difficulty, and the teacher student that wants help repeats, and just can make the correct tone pronunciation of students.In exercise process, teacher normally writes on the blackboard phonetic, then constantly changes tone and allows student pronounce.Yet this exercise mode is more uninteresting, can not improve student's learning interest.
Utility model content
The utility model, for the problem in background technology, proposes a kind of spelling tone excise device, to improve student's learning interest.
The utility model, for overcoming the above problems, adopts following technical scheme:
A spelling tone excise device, comprises substrate, microcontroller, motor-drive circuit and the blank of being located at substrate front side; On described blank, be printed on four line lattice; The top of described blank is provided with a tone rotating disk; One side of described tone rotating disk is provided with a pointer; The back side of described tone rotating disk is provided with a motor; The turning axle of described motor is connected with the central shaft of tone rotating disk; The top of described substrate is also provided with a button; Described microcontroller is controlled machine operation by motor-drive circuit; Described button is connected with the signal input part of microcontroller.
Preferably, described motor adopts stepper motor.
Technique effect:
1, the utility model produces different tones by rotating disk and allows student carry out pronunciation exercises, has certain interest, can improve student's learning interest.
2, substrate front side of the present utility model is provided with blank, is convenient to teacher different initial consonants and simple or compound vowel of a Chinese syllable are write in four line lattice, to help student more comprehensively to practise.
3, the utility model design is ingenious, simple to operate, is convenient to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit structure block diagram of the present utility model.
Label title in Fig. 1: 1, substrate; 2, blank; 3, four line lattice; 4, tone rotating disk; 5, motor; 6, pointer; 7, button.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, the blank 2 that comprises substrate 1, microcontroller, motor-drive circuit and be located at substrate 1 front; On described blank 2, be printed on four line lattice 3; The top of described blank 2 is provided with a tone rotating disk 4; One side of described tone rotating disk 4 is provided with a pointer 6; The back side of described tone rotating disk 4 is provided with a motor 5; The turning axle of described motor 5 is connected with the central shaft of tone rotating disk 4; The top of described substrate 1 is also provided with a button 7.
As shown in Figure 2, described microcontroller is controlled motor 5 work by motor-drive circuit to circuit structure of the present utility model; Described button 7 is connected with the signal input part of microcontroller.
Described motor 5 adopts stepper motor; The L288N doube bridge driver of the main YouST of described motor-drive circuit company forms, for stepper motor is controlled; Described microcontroller adopts the P89V51RD2FBC of NXP company, and it has advantages of that volume is small and exquisite; Described button 7 adopts self-replaced type button; Described tone rotating disk 4 be shaped as circle, on tone rotating disk 4, be printed on four tones of phonetic; The syringe needle of described pointer 6 points to tone rotating disk 4.
During use, teacher can be placed on substrate 1 on dais, then in four line lattice 3, write initial consonant and the simple or compound vowel of a Chinese syllable of phonetic, afterwards, be a teacher and press the button at 7 o'clock, microcontroller can be received the signal that button 7 transmits, and control motor 5 and rotate at random certain angle, tone rotating disk 4 can be followed motor 5 and be rotated together, when motor 5 stops operating, pointer 6 can point to a tone on tone rotating disks 4, and the initial consonant in this tone and four line lattice 3 and simple or compound vowel of a Chinese syllable are common forms a complete phonetic, now, teacher allows student carry out pronunciation exercises again.Afterwards, teacher only need press the button 7 repeatedly, just can help student to carry out the not pronunciation exercises of same tone.
