Cov xov hlau yog qhov tseem ceeb rau kev siv hluav taws xob los ntawm ib qho mus rau lwm qhov. Cov no ua lub luag haujlwm tseem ceeb hauv tib neeg lub neej. Peb cuam tshuam nrog ntau cov xov hlau pib los ntawm lub mloog pob ntseg mus rau TV. Peb muaj tag nrho cov xov hlau khiav sab hauv phab ntsa tsuas yog kom muaj phab ntsa zoo saib. Thaum muaj qee yam tshwm sim rau cov xov hlau zoo li luv Circuit Court lossis xaim xaim peb yuav tsum hloov lawv. Tab sis cov xaim nyob sab hauv phab ntsa yuav nyuaj heev rau nrhiav. Hauv Cov Lus Qhia no kuv yuav qhia yuav ua li cas thiaj ua kom lub xov tooj hluav taws xob nrhiav pom lub mloog xov tooj cua uas tuaj yeem qhia pom tias muaj cov xaim hluav taws xob nyob ib puag ncig nws.
Kauj Ruam 1: Tau Cov Khoom
1. Resistors: lauj kaub 22K, 10K, 1M, 4K7, 100K, 3K9, 1K5, 100K, 100 Ohm, 10K.2. Capacitors: 100nF 63V, 1µF 63V, 10µF 25V, 470µF 25V.3. Diode: 1N41484. Microphone 5. Transistors BC 547 thiab BC 537. 6. 1.5V battery.7. 3.5 hli Jack 8. Lub mloog pob ntseg kom ntes lub suab 9. Ib qho me me inductor coil 22 Gauge 4 tig thiab 4mm txoj kab uas hla.
Kauj Ruam 2: Daim Duab Circuit:
Txuas lub Circuit Court raws li qhia hauv daim duab. Kuv tau txuas tus PCB tsim rau tib yam yog tias koj xav ua qhov no ua qhov ntsuas. 1.5V qhov hluav taws xob xav tau thiab nws muaj lub zog siv qis heev piv txwv li 7.5mA. Koj tseem tuaj yeem txuas 3V cell. Txwv tsis pub, koj tuaj yeem txuas txhua yam mus rau lub rooj ua kom zoo nkauj thiab tom qab ntawd siv cov txheej txheem txheem hlau zoo ib yam li kuv tau ua ntawm no. Koj tuaj yeem rub tawm txhua cov ntaub ntawv xav tau ntawm no.
Kauj ruam 3: Ua haujlwm
Nws tsuas yog ib lub tshuab hluav taws xob txuas nrog lub teeb liab tas li. Ntawm no qhov dav dav nyob ib puag ncig 1V qhov siab tshaj plaws. Rau lub hom phiaj ntawm xaim nrhiav cov tswv yim yuav yog cov kauj me me. Nws yuav tau txais lub teeb liab hluav taws xob los ntawm cov xov hlau thiab xaim tuaj yeem kuaj pom. Hauv daim ntawv thov no, peb tsis tuaj yeem siv lub tshuab ntsuas hlau vim tias lawv yuav txheeb xyuas cov hlau txuas uas muaj tam sim no hauv phab ntsa ua cov xov hlau. Yog li peb yuav tsum siv lub tshuab hluav taws xob txhawm rau txhawm rau txheeb xyuas qhov muaj cov hlau. Thaum nws pom cov xov hlau nqa tam sim no nws tsim lub tshuab nqus hlau uas cuam tshuam lub teeb liab ntawm qhov kawg nkag. Qhov no ua rau muaj suab nrov ntawm qhov tso tawm. Qhov no tuaj yeem txheeb xyuas qhov muaj cov xaim hla cov phab ntsa tuab. Hauv hom microphone, qhov no ua raws li lub tshuab mloog hluav taws xob lossis lub pob ntseg hnov zoo nrog lub suab zoo heev. Vim qhov Circuit no yog 4 theem amplifier nws kuj ua haujlwm zoo li lub pob ntseg hnov pob ntseg. Koj tuaj yeem siv lub microphone ntawm lub tswv yim piv txwv hloov inductor los ntawm lub microphone. Please pov npav rau kuv hauv kev sib tw. Ua tsaug ntau
