Description
Technical field
The utility model belongs to a kind of electronic sound-producing device, and concrete is to discern two-dimentional identification code image, and the device that can pronounce according to image, and particularly identification and sounding parts are split, device that can wireless transmission.
Background technology
Current, there be a kind of " two-dimentional identification code recognition and sounding apparatus " to begin to enter actual operational phase.This device is more common in " pronunciation pen ".Pronunciation pen is provided with form of a stroke or a combination of strokes tubular shell, is provided with a circular hole at the front end of this housing, is provided with in this housing: camera and circuit such as relevant power supply, identification, coding, decoding, compress speech, storage, decompression, audio frequency amplification.During " pronunciation pen " work, the front end circular hole that camera is housed aimed at literal or image recognition district on the carrier be printed on image, literal and corresponding two-dimentional identification code, camera and photoelectric switching circuit become electric signal with the image transitions of the two-dimentional identification code of correspondence, calibrated again identification circuit of this signal and decoding circuit become gets address signal, determine corresponding sound signal memory cell address through CPU, and there is the voice signal in the storer in taking-up, through decompressing and amplifying, give the loudspeaker that is arranged in the handwriting and sound again.This but " pronunciation pen " is being subjected to certain restriction in use: 1. volume is little, only is fit to use when the individual reads.2. be subjected to the size of pen and the restriction of loudspeaker bore, tonequality is poor.Therefore, need to propose better to be suitable for the better two-dimentional identification code recognition and sounding apparatus of function.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, and overcomes that existing Sounding pen volume is little, lower tone, is not suitable for imparting knowledge to students or disadvantage that the collective study occasion is used, proposes a kind of split type two-dimentional identification code recognition and sounding apparatus.
The purpose of this utility model is achieved through the following technical solutions: a kind of split type two-dimentional identification code recognition and sounding apparatus, be provided with housing, camera, image processing circuit, audio frequency processing circuit, acoustical generator, it is characterized in that: described housing is made as the emission housing and receives two split housings of housing, the emission housing is the form of a stroke or a combination of strokes or clavate, teacher's pointer shape, tubular shell, front end at this housing is provided with a circular hole, is provided with in housing: camera and photoelectric switching circuit, image acquisition circuit, transmitter and feed circuit; Described camera and photoelectric switching circuit, image acquisition circuit, transmitter and feed circuit are electrically connected successively; Feed circuit are powered with camera with aforementioned each circuit and are connected;
Described reception housing is a nonmetal casing, be provided with receiving circuit, identification code decoding circuit, correction and the identification circuit, anti-jamming circuit, audio decompression circuit, audio frequency preamplifying circuit, audio frequency correction circuit, audio defeat circuit, the audio power amplifying circuit that are electrically connected successively in this housing, also be provided with storer, central processor CPU and feed circuit; CPU and identification code decoding circuit, rectification identification circuit and storer carry out control linkage; Feed circuit are powered with aforementioned circuit and are connected.
During the work of this device, the circular hole aligning that the emission housing front end of camera is housed is printed on carrier, image on (referring to the label in the accompanying drawing 1 1), literal and corresponding two-dimentional identification code, camera, photoelectric switching circuit and image acquisition circuit become electric signal with the image transitions of the two-dimentional identification code of correspondence, and this signal is directly sent by transmitter.After the reception housing receives this signal by its receiving circuit, become through identification code decoding circuit, correcting circuit and identification circuit and to get address signal, determine corresponding sound signal memory cell address through CPU, and there is the signal in the storer in taking-up, after anti-jamming circuit, audio decompression circuit, audio frequency preamplifying circuit, audio frequency correction circuit, audio power amplifying circuit are handled, sound by loudspeaker.
The beneficial effects of the utility model are: two-dimentional identification code recognition device and receiver pronunciation device are placed respectively, realized signal transmission between them by Wireless transmission mode, solved that volume in the original device is little, the problem of lower tone.The utlity model has simple structure, convenient for production, in classroom instruction, group instruction, various display and demonstration activity, can produce the advantage of beneficial effect.
