Kauj Ruam 2: LM555 piav qhia
555 yog lub cuab yeej ruaj khov heev rau kev tsim lub sijhawm ncua lossis ua kom nrawm. Lub davhlau ya nyob twg ntxiv tau muab rau kev ua lossis rov pib dua yog tias xav tau. Rau kev ua haujlwm ruaj khov raws li oscillator, kev khiav haujlwm dawb thiab lub voj voog ua haujlwm tau raug tswj nrog ob sab nraud sab nraud thiab ib lub capacitor. Lub Circuit Court tuaj yeem tshwm sim thiab rov pib dua ntawm cov nthwv dej poob, thiab cov hluav taws xob tso tawm tuaj yeem ua rau lossis poob mus txog 200mA lossis tsav TTL Circuit Court.
Kauj Ruam 3: LM386 piav qhia
LM386 yog lub zog siv hluav taws xob tsim los siv rau hauv cov khoom siv hluav taws xob qis. Qhov tau txais yog teeb tsa sab hauv rau 20 kom ua rau sab nrauv suav qis, tab sis kev ntxiv sab nraud sab nraud thiab lub peev xwm nruab nrab ntawm tus pin 1 thiab 8 yuav nce qhov nce mus rau ib qho txiaj ntsig ntawm 20 txog 200.
Cov tswv yim nkag hauv av tau hais txog thaum lub zog tso tawm ncaj qha rau ib nrab ntawm qhov muab hluav taws xob.
Kauj Ruam 4: Ua Haujlwm & Xeem
LM555 yog siv los tsim lub teeb liab. LM555 tau txuas nrog xws li nws yuav ua rau nws tus kheej thiab khiav dawb raws li qhov ua tau zoo ntau yam. Tus capacitor sab nraud them los ntawm Ra+Rb thiab tso tawm los ntawm Rb. Yog li lub luag haujlwm voj voog yuav raug teeb tsa los ntawm qhov sib piv ntawm ob tus tiv thaiv no.
Hauv hom kev ua haujlwm no, lub capacitor tsub thiab tso tawm ntawm 1/3 VCC thiab 2/3 VCC. Li no tus nqi thiab lub sijhawm tso tawm, thiab yog li qhov zaus yog ywj siab ntawm qhov muab hluav taws xob.
Kev hloov pauv ib ntus ua raws li cov lus tawm tswv yim uas ua rau astable multivibrator tsim lub teeb liab ntawm qhov sib txawv. Lub teeb liab no raug xa mus rau chav ua haujlwm ua ntej nws tau ua los ntawm tus hais lus. Qhov zaus thiab ntim ntawm lub suab raj tuaj yeem sib txawv raws li qhia.
Kauj Ruam 5: Circuit Schematic
Lub hwj chim potentiometer R3 (Rb) tau hloov pauv kom hloov pauv zaus ntawm lub teeb liab tsim los ntawm LM555. Lub teeb liab tau dhau mus rau LM386 rau kev nthuav dav.
Lub teeb liab nkag tau dhau los ntawm lwm lub zog R4 ua ntej nws mus txog LM386. Lub lauj kaub no yog siv los hloov qhov dav (ntim) ntawm lub teeb liab tawm ua ntej ua kom nrov nrov.
LM386 muaj 10uF capacitor thiab 10K potentiometer R5 txuas nrog ntawm tus pin 1 thiab 8.
Los ntawm kev sib txawv lub lauj kaub no, peb tuaj yeem hloov pauv qhov nce ntawm lub suab nrov thiab yog li qhov ntim ntawm lub teeb liab tau nce.
Lub laub-khawm/ hloov pauv ib ntus yog siv los qhib lub Circuit Court ua rau lub suab nrov nrov.
Cov capacitors txuas nrog hla cov khoom siv hluav taws xob tau siv los txo qis cov suab nrov.

Kuv tsim lub rooj tsavxwm uas siv Txoj Kev Hlau.
Kuv drilled plaub qhov sib dhos hauv txhua lub ces kaum nrog txoj kab uas hla ntawm 3mm.
PCB loj yog 7.5cm X 5cm
Kauj Ruam 7: Circuit Court Assembly
Muab thiab ua kom tag nrho cov khoom siv rau PCB. Txheeb xyuas ob lub Cheebtsam nrog polarities. Thaum kawg, muab lub Hwj chim adapter thiab tus hais lus rau PCB.
Kauj Ruam 8: Kho Tone & Volume
Koj tuaj yeem hloov lub suab nrov thiab ntim ntawm lub tshuab raj los ntawm kev hloov txoj haujlwm ntawm lub hwj chim uas siv lub taub hau ntswj taub hau.
Potentiometer R3 tau hloov pauv lub suab nrov (zaus) ntawm lub suab raj. Potentiometer R4 yog siv los hloov qhov ntim (lub zog nce ntxiv) ntawm lub suab raj.
