Description

Sound imitation handicraft article

This is novel to relate to a kind of handicraft of viewing and admiring that can imitate people's language.

Existing all kinds of handicrafts on the domestic market can only play vision and view and admire effect, and can not oneself send voice at present, and minority handicraft energy sounding is arranged, but also only can send music or dull sound.The present existing toy that can imitate people's language on the market, but the circuit of its composition is complicated is operated more loaded down with trivial detailsly, and power consumption is more.

This novel purpose is exactly to manufacture a kind of novel handicraft, and this handicraft can also have the function of the imitation mankind or other animal voice when viewing and admiring for people, can repeat with the external voice typing and with distinctive tone and reset.This handicraft series also has to be used simply, and power consumption is low, interesting strong characteristics.

This novel function is achieved in that in the shell appropriate location of handicraft model installs indicator lamp and power switch, the chamber is installed an electronic speech record, is put device within it, and this device mainly is made up of speech path controller, memory, plan sound controller, electronics audio-switch, power amplifier, loudspeaker, sound pick-up and battery.Language processor is connected with sound pick-up, electronics audio-switch, plan sound controller, power amplifier, memory respectively.Its groundwork process is as follows: the user is talking in the certain distance of this handicraft, its voice signal enters the electronics audio-switch by sound pick-up, the electronics audio-switch is exported an electric pulse immediately, start speech path controller and enter duty, the language processor received speech signal is sent in the memory after converting digital information to through wherein A/D, through behind the certain hour, the language message that speech path controller will be stored in again in the memory is taken out, sending into wherein D/A change-over circuit is reduced to voice signal and send power amplifier to amplify through filter circuit, signal after the amplification is sent into the loudspeaker sounding, sounding can be continuous, the effect of intending the sound controller is a control language amplifier sample frequency, make it low when when recording, sample frequency was than playback, thereby the voice signal frequency spectrum after the reduction is moved to higher frequency band, realized the plan audio fruit of imitation parrot sounding.This handicraft can be made the moulding of birds or other animal.

Below in conjunction with accompanying drawing this novel practical example is elaborated.

Fig. 1 is this novel structure chart.

Fig. 2 is this novel electrical principle block diagram.

Fig. 3 is that this novel electrical equipment connects by figure.

1 is the shell of handicraft among Fig. 1; The 2nd, indicator lamp; The 3rd, sound pick-up; The 4th, electric elements; The 5th, power switch; The 6th, loudspeaker; The 7th, battery case; The 8th, support.

9 is speech path controllers among Fig. 2; The 10th, memory; The 11st, sound pick-up; The 12nd, the electronics audio-switch; The 13rd, power amplifier; The 14th, loudspeaker; The 15th, intend the sound controller; The 16th, power supply.

VTV001B is the speech path controller integrated circuit among Fig. 3; The 41256th, memory integrated circuit; D2283 is a power amplifier integrated circuit; LM324 intends sound controller and electronics audio-switch integrated circuit; V1, V2V3 are transistors.

The function of each part mentioned above is: speech path controller 9 mainly is logic control, amplifies pickup signal, and signal is carried out modulus and digital-to-analogue conversion, the signal of control memory;

The function of memory 10 is the digitized voice signals of storage; The major function of electronics audio-switch 12 is to start speech path controller 9 after detecting voice signal; The major function of intending sound controller 15 is the sample frequency of the automatic control language controller of duty (recording or playback) according to speech path controller 9; The function of power amplifier 13 is the audio signals of amplifying speech path controller output, promotes loudspeaker 14 work; The function of power supply 16 is to provide electric energy to each electric elements.

The operation principle and the function of this apery language handicraft are as follows: when the people faces toward this handicraft speech in certain distance, it notes the voice signal of certain hour at once, repeat playing is come out then, can be continuously several times, can repeat said process again then, when people's silent or this people's intensity of sound is not enough to start electronic switch till.1,2 pin of speech path controller integrated circuit VTV001B are oscillator outer meeting resistance end, link to each other with plan sound controller 15; 3 pin ground connection; 5 pin are the work trigger end, link to each other with electronics audio-switch 12; 6 pin are playback number of times control end; 8 pin are the indicator lamp control end; 9 pin are microphone ground connection output; 10 pin are the microphone input; 13 pin are audio signal output end; 15 pin are the mode of operation control end; 14,16 pin are automatic playback number of times control end; 17,18 pin are that external memory sheet is counted the selecting side; 20 pin are the VCC power input: 21 pin are the open-drain output, and output high level during playback, stops to the power amplifier power supply to reduce the power consumption of holding state during non-playback to power amplifier 13 power supply by V2; 22 pin are the open-drain output, by the feeder ear of V1 control memory 10, and the power consumption during with the reduction standby; 23,25,26,27,28,29,30,31,37 pin are the rank addresses output, link to each other with the respective foot of memory 10;

24 pin are the VDD power end; 32 pin are the read control signal end; 33 pin are that data are read in end; 34 for pin be the write signal control end; 35 pin are that sheet selects control end; 36 pin are data output end.33,34,35,36 pin link to each other with the respective pin of memory 10.NM all the other pin need not.

After power switch was connected, this handicraft just was in holding state.When the people when in this handicraft certain distance, talking; its voice signal is at first detected by the electronics audio-switch; by electronics audio-switch 12 pulse signal of the 5th pin output to speech path controller 9; make it to enter recording state, this moment, indicator lamp 2 was bright, memory 10 work; speech signal is coupled to the 11st pin of speech path controller 9 and enters speech path controller through sound pick-up 11 and amplifies; through the A/D converter sampling, behind amount guarantorization and the coding, become digital information and deposit in the memory 10.Recording finishes, speech path controller the 8th pin becomes high level, indicator lamp goes out, then, speech path controller just enters tone playing state, with the digital information in the memory, after the D/A conversion, be reduced to voice signal, through the 13 pin output of speech path controller, send into the 5th pin of power amplifier 13 through filter network, after power amplifier amplifies, send into loudspeaker 14 from its 8th pin output, loudspeaker 14 comes again user's language, then, entire circuit repeats said process once again, and loudspeaker 14 repeats a user's language again, and circuit enters holding state again subsequently.

When playback, 8 pin of speech path controller are high level, and this pin links to each other with the input of intending sound controller 15, make its change in resistance, sample frequency when causing the sample frequency of speech path controller to be higher than recording, thus the frequency of output voice changed, realized plan audio fruit.

The shell 1 of this handicraft can be manufactured with paper shell or plastics, also the available metal skin.Available long and short flannelette or all kinds of fur apply lid to increase vivid effect above the shell.Support 8 is made by plastics or foil.Battery case 7 is made by plastics or thin metal skin, and the outer painting of also available paper shell is made.Indicator lamp 2 is installed in the eye of animal artware moulding.Power line is led to the electric elements and the circuit board of inner chamber by animal-shaped foot.
