Description

Electronic bird for heralding the break of day which immitating the speak of people

The utility model belongs to the doll class, relates in particular to a kind of anthropomorphic dummy and replys the light-operated electronic bird that heralds the break of day of speaking.

Existing Toy bird is mostly for viewing and admiring shape, do not have a utility function.As, the tool function etc. of heralding the break of day not.

But the purpose of this utility model is to provide a kind of to be integrated the anthropomorphic dummy simple in structure, that cost is low who views and admires with utility function and replys the electronic bird of speaking and can herald the break of day.

The utility model is realized by following scheme: be provided with light-operated circuit and electronics recording and playing circuit in the tripe abdomen of bird.Light-operated circuit is made up of phototriode, oscillation circuit, hummer and power supply.Phototriode is experienced illuminance, and when irradiate light, the phototriode electrorheological is big, makes oscillator work, promotes buzzer call, works the effect of heralding the break of day.The electronics recording and playing circuit is made of sample circuit, Language Processing integrated circuit, language storage integrated circuit, audio amplifier circuit and on-off circuit.Sample circuit becomes electric signal with voice conversion, delivers to the Language Processing integrated circuit after the amplification, and treatment conversion or data mode leave language storage integrated circuit in, realize the unrecorded tape recording.Subsequently, the Language Processing integrated circuit is transformed into tone playing state automatically, takes out the data-signal conversion from the language memory circuit, synthesizes sound signal, after audio amplifier circuit amplifies, promotes the loudspeaker sounding.

One is viewed and admired and be useful for to the utility model collection, but the anthropomorphic dummy reply and speak and have the function of heralding the break of day, good looking appearance, simple in structure, cost is low and easy to use.

Fig. 1: be outside drawing of the present utility model.

Fig. 2: be light-operated circuit figure of the present utility model.

Fig. 3: be electronics recording and playing circuit figure of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated.

The utility model is made up of the plastics bird 1 that stand on the support 5, its belly and back are covered with down cloth 3, wing and tail constitute by feather 2, and eyes are made of colored beading 4, are provided with control circuit in the body of bird 1, comprise light-operated circuit and electronics recording and playing circuit, light-operated circuit is by triode BG1, BG2, biasing resistor R1, R2, capacitor C 1～C4, transformer B, hummer Y1 and DC source E form.Triode BG1, be phototriode, it and resistance R 1 series arm cross-over connection are between power supply E positive pole and triode BG2 base stage, biasing circuit as triode BG2,2 cross-over connections of feedback coupling capacitor C are between triode BG2 base stage and coupling transformer B primary coil, and hummer Y1 cross-over connection is in coupling transformer B secondary coil two ends, and capacitor C 3 constitutes oscillation circuit with the primary coil of transformer B, between capacitor C 4 cross-over connection positive sources and negative pole, its positive pole is connected to the center tap of transformer B primary coil.Its principle of work is as follows: do not have rayed night, the electric current that flows through phototriode BG1 is minimum, and triode BG2 is in cut-off state, not starting of oscillation of oscillation circuit, thereby hummer sounding not.When early morning, the sky brightened gradually, the photocurrent that produces among the phototriode BG1 increased gradually, and photocurrent flows into triode BG2 base stage through resistance R 1, and up to triode BG2 conducting, the oscillation circuit starting of oscillation promotes hummer Y1 sounding, plays the effect of heralding the break of day.

Sample circuit in the electronics recording and playing circuit of the present utility model is made up of microphone MIC and resistance R 3, R4, R5 and capacitor C 5～C7, and resistance R 5 and capacitor C 5, C6 form low-pass filter, strobe.Microphone becomes electric signal to deliver to Language Processing integrated circuit (IC) 1 input end through the filtering amplification language conversion.Language Processing integrated circuit (IC) 1 adopts YD-9307, its I/D end pin 20～28 meets the address end A0～A8 of language storage integrated circuit (IC) 2 successively, and the electric signal that Language Processing integrated circuit (IC) 1 is exported sample circuit is processed into data-signal and delivers to language storage integrated circuit (IC) 2.Audio amplifier circuit of the present utility model is by audio frequency amplification circuit IC3, loudspeaker Y2 and resistance R 6～R8, and capacitor C 8～C14 forms.Language Processing integrated circuit (IC) 1 output signal is delivered to audio frequency amplification circuit IC3 input end through capacitor C 8, resistance R 6, R7, R8, and resistance R 6, R7, R8 and capacitor C 9, C10, C11 form low-pass filter, with the interference that abates the noise.Audio frequency amplification circuit IC3 output is delivered to loudspeaker Y2 through capacitor C 14.On-off circuit of the present utility model is by triggering integrated circuit (IC) 4(MC140B), pushbutton switch SA, triode BG3 and resistance R 9～R12, capacitor C 15 are formed.Pushbutton switch SA and resistance R 9 series arm cross-over connections are in+5V and trigger between integrated circuit (IC) 4 input ends, trigger integrated circuit (IC) 4 output terminals and connect triode BG3 base stage through resistance R 12, its collector connects audio frequency amplification circuit IC3 input end, and emitter connects+the 5V power supply.

The principle of work of the utility model electronics recording playback sound is as follows: click pushbutton switch SA, a low level is exported in power supply trigger circuit IC4 work, makes triode BG3 saturation conduction, i.e. power connection power supply.Language Processing integrated circuit (IC) 1 is operated in recording state earlier, and this moment, microphone was said in short, and the electrical signal conversion that microphone is converted to becomes data-signal to leave language storage integrated circuit (IC) 2 at once, realizes the unrecorded tape recording.Subsequently, Language Processing integrated circuit (IC) 1 is transformed into tone playing state automatically, from language storage integrated circuit (IC) 2, take out data-signal and be recycled to Language Processing integrated circuit (IC) 1, the treated sound signal that synthesizes, amplify output through audio frequency amplification circuit IC3, promote loudspeaker Y2 sounding, carry out so repeatedly, realize automatic answer function.Click pushbutton switch SA again, trigger integrated circuit (IC) 4 and be reversed, export a high level, triode BG3 is ended, stop circuit supply, each several part quits work.
