The utility model is capable of detecting external voice automatically and auto-repeating various languages and songs, etc. The utility model is characterized in that a circuit is provided with the function of external speech detection and only if the external voice is detected, the circuit starts a coding and decoding circuit to start to repeat people's words, which ensures that the utility model can repeat people's words at any time when people speak in the using process. The utility model can also adjust the speeds and tones of the repeating words as required.

Description

Electronic toy capable of auto-repeating people's words

The utility model relates to a kind of electronic toy of the words of theory automatically, belongs to articles for daily use--electronics.

Along with people's living standard improves constantly, market is more and more urgent to the demand of intelligent toy.People wish to obtain a kind of speech, the song that can experience the people at any time, and the electronic toy of automatic theory words, and more existing acoustic toys can not satisfy this requirement far away on the market.Aspect sounding, now seen toy is state-of-the-art on the market two kinds, and a kind of is to send one or more fixing sound, as laugh or several simple sentence.Though another kind of energy parrotry, but there are three subject matters in it: one, it has fixing recording and playing time section, if the people speaks in its playback section, then it can not repeat at all, that is to say that it can not be discerned external voice automatically and make and replying, opposite, in order to allow it can learn words, the people speaks in the section at a fixed time.Two, the speed and the tone of repetition speech are non-adjustable.Condition promptings such as three, not recording of this toy, repetition, this just causes the user to be difficult to judge its present located state.These problems reduce the level of intelligence of toy and interest greatly.

The purpose of this utility model provides a kind of novel intelligence toy of speaking, it has following main feature: one, the user can be at any time to its speech, after it detects external speech, just start record, discharge road automatically, begin to learn words, and when not having outside speech to be detected, it is in wait state all the time.When two, learning words, the speed and the tone of voice are adjustable.Three, it has the work at present status indicator lamp.

For achieving the above object, the utility model is made of following several functional blocks on circuit: sound collection and amplification, external sound detection, control, oscillator frequency adjustment, voice signal coding and decoding, current state indication, repetition sound amplify driving.

When not detecting external sound, circuit is in wait state, have only sound collection, amplification, detection, control this a few partial circuit work, and other each several part is in the low-power consumption wait state.The signal that testing circuit is sent the collection amplifying circuit here compares with selected threshold values after level and smooth, after the smooth value of external voice signal is higher than the comparison threshold values, just start coding circuit automatically by control circuit, indicator lamp is lighted the current recording state that is in of indicating circuit simultaneously.After recording finishes, start the decoding playback circuit again automatically, emit the repetition voice, extinguish indicator lamp simultaneously, indication circuit has entered tone playing state.After playback finished, circuit entered wait state again, just restarted when detecting external sound once more, entered the above-mentioned course of work.

Advantage of the present utility model has: (1) is provided with the audio-switch of the external sound of automatic detection, and speech is replied at any time at any time; (2) speed and the tone of theory words are adjustable; (3) be provided with the work at present status indicator lamp; (4) in wait state, most of circuit is in low power consumpting state, and whole power consumption is descended; (5) board design is small and exquisite, and size only is 13.4 * 3.5mm; (6) be core with this circuit board, equipped different overcoats are adjusted speech speed and tone again, are easy to constitute various theory words toys, and the product line extended capability is strong.

Accompanying drawing the 1, the 2nd, circuit theory diagrams of the present utility model.

Below in conjunction with accompanying drawing the utility model embodiment is further described.

During unmanned on every side the speech, circuit is in wait state.R1, MIC, C1, R2, R3, R17 and U3 have constituted voice collecting and amplifying circuit, and the voice signal SIG through amplifying as the input of back level rectifier smoothing circuit, sends into U1 on the one hand on the other hand, prepares to carry out △ M coding.After the SIG signal passes through the rectifier smoothing circuit that is made of D, R5, C3, R6, send into comparator U4, when external voice make this signal greater than the thresholding determined by R7, R8, U4 exports a rising edge, this rising edge is as triggering signal, start U1, begin to enter the encoded audio record state, indicator lamp LED lights simultaneously.After recording finishes, utilize the rising edge of the LEDO pin output of U1 to trigger the TRIG pin automatically, make U1 enter the decoding tone playing state, by AUDO pin output decoding synthetic speech signal.After repetition finished, entire circuit entered wait state again.

U5 is a memory, is used for keeping in coded data.C8, C9, C10, C11, R15, R18, R19 and U2 constitute amplification driving circuit, promote loudspeaker, and voice are repeated in output.

The DRAMPO of U1 and TGFO pin are power supply control, have only circuit be in record, when putting state, DRAMPO is in low level, power supply ability is powered to U1, U5; Have only circuit to be in tone playing state, TGFO is a high level, and U2 just is powered.

It is slack-off to learn words speed when SW2 pushes position 1, and tone is overcast, when pushing position 2, learns words and speeds up the tone taper.This is to have utilized the LEDO pin in the recording state output low level, and in the characteristics of other state output high level, make the grid of J obtain different control voltage at record, the state of putting, thereby J has different drain-source conducting resistance, also just produced different frequencies of oscillation, final speed and the tone of learning words that change.Regulate R20 and can continuously change speed and the tone of learning words.In addition, the SPEED pin of U1 connect high level can make repeat speech speed up one times.
