Description
[technical field]
The utility model relates to talking pen, especially a kind of talking pen with change of voice function.
[background technology]
At present; E-education market is very fiery; The audio-visual education programme product replaces the trend of the auxilliary religion of traditionally on paper product more and more obvious, so, occurred on the market like study aids such as talking pen, language repeater, student's computing machine, learning machines; Wherein, Talking pen is one of preferable selection of people, talking pen adopted that high parsing optics is distinguished stealthy sign indicating number technology, digital speech is synthetic with reduction technique, digital signal information treatment technology, numeral between deposit technology and image processing techniques, be one with the shallow sign indicating number of two dimension technology, the digital optical technology of microspur, compress speech and play-back technology and the technological high-tech product that combines of paper printing.The high optical identification of resolving replaces electromagnetism identification; The 2 d code digit recognition replaces simulation identification; Fundamentally remove the electromagnetic radiation hidden danger that former talking pen brought, possessed advantages such as anti-interference, anti-Japanese light modulation, anti-tide, anti-electromagnetic wave, anti-health static simultaneously.At present; Talking pen on the market is of a great variety, but existing talking pen general utility functions are single, does not consider comprehensive needs of child teaching; Can not remove the directs excitation children thought from many aspects; Therefore, still there is certain defective in existing talking pen, can not satisfy the increasingly high requirement of user.
[summary of the invention]
The purpose of the utility model is to overcome deficiency of the prior art, and a kind of talking pen with change of voice function is provided.
The technical scheme of the utility model is achieved in that it comprises form of a stroke or a combination of strokes fuselage; Said form of a stroke or a combination of strokes fuselage comprises housing and is arranged at the control circuit in the housing; Said control circuit comprises micro-control unit and the stealthy sign indicating number identification circuit, feed circuit, power amplifier and the storer that electrically connect with micro-control unit; The output terminal of said power amplifier electrically connects a loudspeaker, and its improvement is: also comprise recording circuit, said recording circuit is electrically connected at micro-control unit.
In the said structure, said micro-control unit comprises signal controlling, data bus and audio frequency DSP.
In the said structure, said micro-control unit electrically connects a reset circuit.
In the said structure, also comprise earphone interface circuit, key circuit, usb circuit and expansion card interface circuit, said earphone interface circuit, key circuit, usb circuit and expansion card interface circuit are electrically connected at micro-control unit.
The beneficial effect of the utility model is: the utility model utilizes recording circuit can carry out machine with the sound of reading, imitate child, plays back with another kind of tone through the micro-control unit decoding again, and is concrete; At first sound is by the recording circuit typing, judges through micro-control unit that its sound has not for effective source of sound again and (sets a sound threshold values, when sound during more than or equal to this threshold values; Be effective source of sound), preserve being judged as effective source of sound again, play back after at last should effective audio file adding audio and change audio frequency; At this moment, the tone that plays back is different with children's tone, by this; Realized change of voice function, let child in study, experience more enjoyment, simultaneously; Can strengthen the desire that baby lifts up one's voice, cultivate child's humorous emotion.

[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described:
With reference to shown in Figure 1, the utility model relates to a kind of talking pen with change of voice function, and it comprises form of a stroke or a combination of strokes fuselage; Said form of a stroke or a combination of strokes fuselage comprises housing and is arranged at the control circuit in the housing; Control circuit comprises micro-control unit and the stealthy sign indicating number identification circuit, feed circuit, power amplifier and the storer that electrically connect with micro-control unit, and the output terminal of said power amplifier electrically connects a loudspeaker, through stealthy sign indicating number sweep circuit stealthy sign indicating number is discerned; Again through the micro-control unit decodes and plays; Realize reading, feed circuit are above-mentioned each circuit supply, and said micro-control unit comprises signal controlling, data bus and audio frequency DSP; In addition; Said micro-control unit electrically is electrically connected with reset circuit, earphone interface circuit, key circuit, usb circuit and expansion card interface circuit, and said earphone interface circuit, key circuit, reset circuit, expansion card interface circuit are electrically connected at micro-control unit; Wherein, earphone interface circuit can insert earphone, through earphone playing back music or voice; The switching on and shutting down of key circuit control talking pen, the switching of function, recording, broadcast etc.; Recording circuit is used to be logged in child's pronunciation, through contrasting self pronunciation and system's pronunciation, can better help child to learn and the grasp standard pronunciation; It is talking pen charging etc. or diode-capacitor storage etc. that usb circuit connects data, and the expansion card interface circuit connects TF card expansion fuselage internal memory; Also comprise recording circuit, said recording circuit is electrically connected at micro-control unit.Utilize this recording circuit can carry out machine, play back with another kind of tone through the micro-control unit decoding again, with reference to shown in Figure 2 with the sound of reading, imitate child; Concrete, its treatment scheme is: a, sound are provided with a sound threshold values by the recording circuit typing in system; When sound import during more than or equal to this threshold values; Be effective source of sound, during less than this threshold values, be invalid source of sound; B, judge through micro-control unit that its sound has and be not effective source of sound that if invalid source of sound then is judged as quietly, the sound of input is not done preservation, if effective source of sound then is saved to storer being judged as effective source of sound; C, the effective audio file that will preserve add audio; D, the audio file that is added with audio is changed audio frequency; E, play this audio file through micro-control unit controls, at this moment, the tone that plays back is different with children's tone; By this, realized change of voice function, let child in study, experience more enjoyment; Simultaneously, can strengthen the desire that baby lifts up one's voice, cultivate child's humorous emotion.
