Description

Chinese phonetic alphabet Received Pronunciation Teaching instrument

The utility model relates to the education demonstration equipment, be meant the extensive speech IC of a kind of employing especially, have that large-scale letter stirs card, sound high-fidelity power amplification multiple height, integrates figure, a multimedia Chinese phonetic alphabet Received Pronunciation Teaching instrument of literary composition, sound.

Existing teaching of Chinese pin yin adopts the teacher to write and impart knowledge to students with self pronunciation and blackboard mostly, because China is vast in territory, dialect is numerous and complicated, and often many teachers itself pronounce and write not enough standard, can not guarantee quality of instruction.Teacher's labour intensity is also bigger simultaneously.Though the apparatus that some are used for teaching of Chinese pin yin also occurred, but since source of sound nonstandard, lack of standardization, the integrated circuit capacity is too little or the production of integrated circuits technology does not pass a test and structure on the design unreasonable can not correctly be used for the teaching, satisfy the teaching requirement, thereby responsible educational institution do not approve, limited the use of these teaching aids.

The purpose of this utility model just is to change the backward situation of present teaching of Chinese pin yin, provide that a kind of speech IC capacity is big, the power amplification of sound high-fidelity more than 100db, adopt the dual-purpose multimedia Chinese phonetic alphabet Received Pronunciation Teaching instrument that integrates figure, literary composition, sound of alterating and direct current.

The utility model external form is a rectangular shape, is the flipover card holder above the first half.Constitute by support, card, cabinet, switch, pilot lamp, volume adjustment knob, soft-touch control, ac plug, loudspeaker and circuit part (integrated circuit and peripheral component).The rectangular parallelepiped cabinet has the support that stirs card above the first part, card such as loose-leaf books shape are fixed on the support, can find needed each the alphabetical standard font and the card of ways of writing by stirring, switch, pilot lamp and volume adjustment knob are housed on the case front panel successively, be equipped with after the cabinet top shelf in loudspeaker and soft-touch control, the cabinet and be circuit part (integrated circuit and peripheral component), the cabinet rear panel is drawn ac plug.Soft-touch control has 55 keys, whole soft-touch control and printed circuit board (PCB) are integrated, printed circuit board (PCB) adopts the old arrangement of square, 55 letters and syllable are integrated in the integrated circuit, each key is a soft-touch control, and the standard source of sound that pronunciation adopts the formal national language and characters Working Committee that publishes to provide is more than the sound high-fidelity power amplification 100db, can be arbitrarily, pronounce to select repeatedly, volume is according to environment occasion difference and step-less adjustment.Card adopts nonabradable high-quality compound substance to make, polyester composite for example, and card sizes is 300 millimeters * 400 millimeters, is furnished with accompanying drawing, standard alphabet block letter and alphabetical integral body on the card and recognizes pronunciation joint Writing method.Comprise that initial consonant, simple or compound vowel of a Chinese syllable, integral body recognizes pronunciation joint totally 64 width of cloth cards.Chinese phonetic alphabet Received Pronunciation Teaching instrument both can use the 220V AC power, also can use the 3-5V direct supply.Directly be positioned on the dais or during teaching and hang on the blackboard curtate.Teacher in teaching process is as long as the graph-text content as required on the comparison card is pressed the soft-touch control key of corresponding character, just can allow the student at a standard classroom or lecture theater hear the Chinese phonetic alphabet of a standard or wholely recognizes the pronunciation that pronunciation saves.

Advantage of the present utility model just is that the speech IC capacity is big, initial consonant, simple or compound vowel of a Chinese syllable pronunciation teaching both can have been carried out, also can carry out the pronunciation that integral body is recognized the pronunciation joint, and pronunciation standard, correct, standard, satisfied the needs of teaching, this Teaching instrument both can use AC power also can use direct supply simultaneously, and was extremely easy to use, and sound height, clear, can be fit to teaching to whole classroom student, alleviated teacher's teaching load; Therefore has development prospect preferably.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a profile synoptic diagram of the present utility model;

Fig. 2 is a circuit diagram of the present utility model.

With reference to Fig. 1, the utility model by support (1), card (2), cabinet (3), open Close (4), indicator lamp (5), volume adjustment knob (6), soft-touch control (7), ac plug (8), loudspeaker (9) and circuit part (integrated circuit and peripheral component) formations such as (10). Support (1) is positioned at the first half above the cabinet (3), also can break away from cabinet (3) and be hung on blackboard On; Card (2) is fixed on the support (1) such as loose-leaf books shape, and its two sides all is printed on Big pinyin character is stirred at support as the loose-leaf books; Cabinet (3) is by ABS Engineering plastics are made, and the devices such as circuit board and loudspeaker (9), loudspeaker (9) are equipped with in its inside Be microphone device, horn mouth is positioned at above the cabinet, the support back, and it selects specification Be 8 Ω, 2W, diameter is 5 cun, and soft-touch control (7) is positioned at loudspeaker (9) above the cabinet (3) Afterwards, totally 55 keys, each key represents a diacritic, soft-touch control (7) with Circuit part (10) is connected as a single entity, and printed circuit adopts matrix circuit with 55 pronunciation collection Be formed among the IC (being integrated circuit, lower same), because square is adopted in IC design Battle array is arranged and has been simplified manufacturing technology, greatly reduces the manufacturing of IC and printed circuit board (PCB) Cost; Ac plug is connected the 220V AC power, and cabinet (3) is also arranged dc source No. 1 battery of 2 joints can be placed in the position, and DC voltage is 3V.
