Nkauj yuav yog yam tseem ceeb. nws yog yuav ua li cas kom meej meej kev xav, Kuv tus kheej hnov tons ntawm cov nkauj. qhov no feem ntau yog kuv qhov kev zais rau kuv lub zog. Txawm tias kuv tab tom sau ntawv nkauj thaum sau ntawv rau koj. Yog li, cia peb dhia mus rau peb lub ntsiab lus Lub suab nrov nrog Transistor (IRFZ44N N-Channel MOSFET).
Lub Circuit Court ua haujlwm li cas? Cov suab qis qis qis tuaj ntawm cov cuab yeej siv tau. Lub teeb liab no tsuas yog qis dhau los mloog nrog Tus Hais Lus. Ntawm no ib tus transistor tau ua haujlwm yog li nws txhais tau tias nws tsuas tuaj yeem muab cov mono tso tawm.
Yog tias koj xav tau Sterio tso tawm koj yuav tsum tau siv 2 IRFZ44N N-Channel MOSFETS. Piv txwv tias peb tab tom tham txog lub teeb liab sab laug. Lub teeb liab sab laug muaj 2 xaim ib qho tuaj yeem yog Sab Laj Teeb Hlau thiab lwm qhov yog GND. GND xaim yog tib yam rau ob sab laug thiab Txoj cai. Tab sis cov xaim xov tooj sib txawv rau ntau txoj hauv kev. Lub teeb liab xaim mus rau hauv Transistor's Gate Pin.
Tam sim no Transistor Hloov Tawm thiab tawm rau qhov tshwm sim zaus. Txog qhov no, Transistor's Drain thiab Source voltage sib txawv. Rau qhov no, cov cim me me yuav raug nthuav dav. thiab yog li ntawd bandwidth kuj yuav siab. Tam sim no peb yuav hnov lub suab nrov los ntawm tus hais lus.

Nov yog Qee Cov Duab rau tsim Circuit. Kuv txawm tias tau ua qhov yooj yim yooj yim Lub tshuab hluav taws xob Circuit Court hauv PCB txhawm rau tsim cov Circuit kom yooj yim li sai tau. koj tseem yuav ua qhov Circuit hauv Breadboard. Tab sis kuj tseem yuav muaj kev sib txuas xoob Yog li kuv txawm tias tau muag ncaj qha tag nrho Cov Cheeb Tsam. Yog li, yuav tsis muaj kev sib txuas xoob.

Nov yog Circuit Court yooj yim. Yog li muaj qee qhov tsis zoo rau hauv Circuit Court. Tias yog vim li cas lub voj voog no tsis yog rau lub hom phiaj thov.
Tsis muaj kev tshem tawm suab nrov hauv Circuit Court. Yog li, koj yuav pom cov suab nrov ntxiv hauv lub suab nrov. Lub tshuab hluav taws xob no tuaj yeem muab lub suab rau koj mloog tab sis tsis muaj suab nrov ntau dhau. Qhov no yog Mono amplifier. koj yuav ua nws Stereo los ntawm kev siv qhov sib npaug ntawm lwm cov kev sib tw.
Muaj qhov ntau dhau ntawm qhov poob hauv Circuit Court. qhov no feem ntau tsis muaj txiaj ntsig zoo. Yog li niaj hnub no Lub tsev ua yeeb yaj kiab thiab lwm lub Tshuab Suab Nkauj siv pawg D lub suab nrov nrov. qeb D amplifier muaj qhov ua tau zoo ntawm 80 txog 90%. The Basic and popular class D amplifier is PAM8403.
Nws tuaj yeem tsav 2, 5W Hais Lus nrog yooj yim. Nws tuaj yeem muab qhov siab tshaj ntawm 10W cov zis. thiab yog li qhov tseem ceeb tshaj plaws yog lub rooj tsavxwm tsis xav tau qhov siab. Nws tuaj yeem khiav nrog 3v txog 5V Hwj chim. nws zoo heev rau Portable Bluetooth Speaker Systems.
Tab sis tuav txhua qhov, nws yog ib qho kev sib tw zoo heev rau tus nyiam ua haujlwm. lawv yuav xyaum ua circuits kom lom zem.
