Puas yog koj nkees nkees kom sawv los tig lub qhov hluav taws xob kom tua/tsis muaj lub cuab yeej siv?, Lossis nkees nrhiav kev hloov pauv hauv qhov tsaus ntuj? Clap hloov yog dab tsi? Clap -switch Circuit yog lub suab pib nkag tau yooj yim, Nws tau tsim los ntawm R Carlile, Stevens, thiab E Dale Reamer thaum 20 Lub Ob Hlis 1996. Kev ua haujlwm ntawm Circuit Court yog qhov yooj yim, Clap thiab cov khoom siv tig rau. Npuaj dua thiab nws tig tawm. Lub condenser microphone khaws lub suab ntawm koj npuaj teg lossis txhua yam ntawm lub suab tsim tawm. 555 yog Timer IC, yog ib qho tseem ceeb tivthaiv, Nws tau siv nyob rau hauv hom monostable hauv qhov kev sib tw no, uas tsuas muaj ib lub xeev ruaj khov {Nco tseg: peb kuj muaj cov qauv zoo thiab zoo nkauj}. Nws tau rov qab los rau nws lub xeev qub thaum lub moos mem tes sab nraud tau muab rau cov oscillator monostable. Ib yam li ntawd, thaum lub 555 timer tau txais qhov yoj yoj ntawm cov tswv yim (txhais tau tias) tus pin 2, nws nkag mus rau hauv lub xeev ruaj khov, thiab LED ntawm tus pin tus pin 3 tau siv los txiav txim qhov tso tawm hauv daim ntawv ntawm lub teeb. Lub mic condenser yog lwm qhov tseem ceeb Cheebtsam hauv Circuit Court uas taug qab lub suab nrov nrov clap raws lub suab ntawm clap thiab hloov pauv lub suab no mus rau qee yam hluav taws xob. Cov hluav taws xob hluav taws xob no yog qhov xav tau nkag mus rau clap switch Circuit.

Khoom siv:

Cheebtsam yuav tsum tau> 555 Timer IC> Ob BC547 Transistor> Resistor {1k, 4.7k, 47k, 100ohms, 330ohms} [Cia R = 47k thiab 100uF = C rau xam lub teeb lub sijhawm, los ntawm kev siv cov mis uas yuav muab tom qab.] > Capacitor {Ob 0.1uF, 100uF}> LED> Condenser microphone> Breadboard> 9v roj teeb

Kauj ruam 1:

Tau txais cov khoom xav tau raws li teev tseg saum toj no.

Kauj ruam 2: NCO TSEG:

Nco tseg cov hauv qab no thaum ua qhov sib txuas ntawm cov khoom sib txawv. > Electret Condenser Microphone [ENM]: qhov no yog hom condenser microphone transducer, Mic. muaj polarity piv txwv li -ve (tsis zoo) thiab +ve (qhov zoo) davhlau ya nyob twg, ntawm lub hauv paus ntawm Mic. lub davhlau ya nyob twg nrog cov cim yog hauv av (-ve) yuav lub dav hlau saib ib feem yog lub tswv yim (+ve).> BC547 transistor: nws muaj polarity qhia hauv daim duab. pin1 = tus sau, tus pin2 = lub hauv paus, tus pin3 = tus xa tawm.> 555 lub sijhawm teev tseg: raws li tau hais ua ntej, nws tau siv nyob rau hauv hom monostable. Txhawm rau kom tau txais tus lej kom raug ntawm lub sijhawm, tso tus timer nrog tus pointer, teev (txiav) tig ntsej muag. Los ntawm sab saud sab saud, cov lej yog 1-4 thiab los ntawm lub hauv paus txoj cai 5-8. Lub sijhawm ntawm lub teeb tuaj yeem suav los ntawm kev siv cov mis; T pulse = 1.1 x RxC.

Kauj Ruam 3: Kauj Ruam rau Cov Lus Qhia Kauj Ruam:

Txuas cov khoom siv hluav taws xob raws li qhia hauv daim duab qhia chaw.> Tso tus neeg nqa khoom (tus pin 1 ntawm lub transistor) mus rau lub hauv paus (tus pin 2) ntawm tus thib ob BC547 transistor thib ob thiab tus emitter ntawm thawj mus rau Circuit -ve.> Los ntawm lub hauv paus ntawm thawj lub transistor, txuas 4.7k mus rau -ve ntawm lub Circuit Court thiab lub microphone mus rau qhov kev taw qhia mus rau +ve los ntawm tib lub hauv paus.> Txuas tus emitter (pin3) ntawm lub transistor thib ob rau hauv Circuit Court -ve. Nco tseg: tus xa tawm ntawm ob lub transistor tau txuas nrog rau -v ntawm lub roj teeb kev taw qhia.> Los ntawm lub hauv paus ntawm lub transistor thib ob txuas 1k resistor mus rau +ve ntawm Circuit Court, thaum los ntawm tus sau ntawm tib lub transistor txuas 330 ohms rau the +ve thiab los ntawm kev sib tshuam nruab nrab ntawm tus neeg sau thiab 330 transistor txuas 0.1uF rau tus pin 2 ntawm 555 timer IC.> Txuas tus pin1 ntawm 555 timer mus rau -v Circuit Court, txuas 4 thiab 8 ntawm 555 timer ua ke rau +ve sab ntawm Circuit, tus pin 7 thiab 6 yuav tsum txuas nrog ua ke, los ntawm Kev Sib Txuas txuas 47k resistor rau +ve Circuit, los ntawm tib qho kev sib txuas txuas 100uF. Los ntawm tus pin5 txuas 0.1uF thiab koom nrog ob lub capacitor {yog 100uF thiab 0.1uF} mus rau -v ntawm Circuit.> Los ntawm tus pin3 (tso tawm ntawm 555 timer) txuas 100 ohms thiab los ntawm tus tiv thaiv txuas LED, nrog loj dua ceg ntawm LED mus rau -ve thaum luv dua rau tus neeg tawm tsam

Kauj Ruam 4: Cov Teeb Meem Teeb Meem Tsis Zoo:

1. Yog tias lub transistor kub tsis muaj lub teeb liab LED thaum koj npuaj, kos thiab xyuas kom tseeb tias Mic. polarity txuas nrog ncaj ncees. 2. Los yog txheeb xyuas qhov polarity ntawm LED. Nco tseg, cov ceg ntev ntawm LED yog lub davhlau ya nyob twg zoo, thaum luv dua yog qhov tsis zoo. 3. Yog tias nws tseem tsis ua haujlwm, txheeb xyuas koj qhov kev sib txuas dav dav thiab paub tseeb tias nws zoo ib yam nrog daim duab qhia chaw.
