Abstract

The utility model discloses an intelligent toy capable of repeating the words of others, mainly comprising a toy casing, a printed board, a sound-changing switch, a microphone, a recording and playing key and a loud speaker. The toy of the utility model is capable of repeating the words of others, singing, sounding and changing sound; when the words are taught to the toy of the utility model by adults, the words repeated by the toy of the utility model can be in the tone of children; when the words are taught to the toy of the utility model by the children, the words repeated by the toy of the utility model can be in the tone of the adults. The toy of the utility model is suitable for the entertainment of extensive children, is an ideal entertainment tool for the adults, and can be served as an answering machine.

Description

Intelligent toy capable of repeating words of others

But the utility model relates to the intelligent toy of a kind of theory words or sounding.

Have both at home and abroad at present a kind ofly can speak, the toy of sounding or theory words, its circuit mainly is to utilize language sheet and language processor to constitute, in it perhaps tone can not change arbitrarily, so this toy is dull, be difficult to cause extensive and long-term interest.

But the purpose of this utility model provides the toy of a kind of meeting theory words, singing, sounding and the change of voice.

The purpose of this utility model realizes by following scheme: learn the words intelligent toy and include loudspeaker SP, toys shell 1, printed circuit board (PCB) 2, microphone 6, record button 3 and playback button 4, printed circuit board (PCB) 2, microphone 6, record button 3 and playback button 4 are arranged in the toys shell 1, printed circuit board (PCB) 2 by speech processing circuit 1., the voice amplifying circuit 2. with power circuit 3. three parts form, its special character is that it also includes cancel 5, cancel 5 is arranged in the toys shell 1,1. described speech processing circuit contains the circuit structure of changing voice, promptly realize that with the serial or parallel connection inductance of determining the sample frequency inductance crystal of the decision sample frequency that the also available conversion of the circuit structure of changing voice is different is realized.

But but the utlity model has theory words, sing, the function of pronunciation and the change of voice, be that the adult teaches the toy word, what toy was said can be child's tone, child teaches the toy word, what toy was said can be adult's tone, the utility model also can be used as the answering machine use in addition, is the desirable apparatus for entertainment of numerous children.

Detail of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the utility model external structure schematic diagram.

Fig. 2 is the utility model circuit block diagram.

Fig. 3 is the utility model circuit theory diagrams.

As Fig. 1, the ear place is provided with record button 3 on rag baby housing 1 a head left side, the auris dextra place is provided with microphone 6, be provided with playback button 4 in the mouth, cancel 5 is set in the nose, be provided with recording playback sound indicator lamp 7 in the eyes, be provided with power switch 8 in the hair, in doll torso, be provided with printed circuit board (PCB) 2, loudspeaker SP and battery bracket.

Also available other toys shell of above-mentioned doll's housing replaces, as the housing of toys such as panda, Donald duck.

As Fig. 2,1. 3. power circuit one the road supply with speech processing circuit, the voice amplifying circuit is supplied with in another road 2., after pressing record button 3, the audio electrical signal that is come by microphone 6 conversions deposits dynamic memor in after the speech processor digitlization, after pressing playback button 4,2. speech processor is taken out existing information and reverted to analog signal by dynamic memor delivers to the voice amplifying circuit.

As Fig. 3, speech processing circuit is 1. mainly by speech processor IC1(YYH-16), dynamic memor DRAM IC2(41256), record button 3(K3), playback button 4(K2), recording playback sound indicator lamp 7(LED1, LED2), microphone 6(MIC) and cancel 5(K4) form, when pressing record button 3(K3), recording playback sound indicator lamp 7(LED1, LED2) bright, aim at the toy head sounding this moment, microphone 6(MIC) just sound can be become the 9th terminal that the signal of telecommunication is sent into IC1, this electric analoging signal becomes digital information and deposits dynamic memor DRAM IC2 in after the IC1 digitized processing, press playback button 4(K2), IC1 then takes out digital information from IC2 and deliver to the voice amplifying circuit 2. by the 10th terminal after converting analog signal to, cancel 5(K4) when disconnecting, the sample frequency of IC1 depends on inductance L 1; Cancel 5(K4) connect after, sample frequency depends on the value in parallel of L1 and L2, the former sample frequency is low, latter's sample frequency height, the sound of recording under previous state sound frequency when a state playback afterwards just can uprise; Sound frequency just can step-down during in the previous state playback for the sound of recording under one state in the back.

The also available T6668 of above-mentioned speech processor, UM5101 wait and realize.

The voice amplifying circuit is 2. by four high guaily unit IC3(LM324), power amplifier integrate circuit IC4(LM386) and loudspeaker SP form, the audio signal of sending into by IC1 after the amplifier of IC3 is amplified again the 7th terminal of another amplifier through constituting emitter follower export power amplifier IC4(LM386 to) input (the 3rd terminal), after amplifying, deliver to loudspeaker SP and send the sound by the 5th terminal.

Power circuit is 3. by No. 5 batteries of 4.5V(three joints) battery and power switch 8(K1) form power switch 8(K1) connect, circuit can be worked.

Claims

1, a kind of words intelligent toy includes loudspeaker SP, toys shell 1, printed circuit board (PCB) 2, microphone 6, record button 3 and playback button 4, printed circuit board (PCB) 2, microphone 6, record button 3 and playback button 4 are arranged in the toys shell 1, printed circuit board (PCB) 2 by speech processing circuit 1., the voice amplifying circuit 2. with power circuit 3. three parts form, it is characterized in that it also includes cancel 5, cancel 5 is arranged in the toys shell 1,1. described speech processing circuit contains the circuit structure of changing voice, and promptly realizes with the serial or parallel connection inductance of determining the sample frequency inductance.

2, words intelligent toy according to claim 1 is characterized in that the crystal of the decision sample frequency that the also available conversion of the described circuit structure of changing voice is different is realized.
