Muaj ob peb qhov kev qhia tawm ntawm kev ua koj tus kheej hais lus rau koj lub mp3 player … thiab lawv feem ntau tsis siv lub suab nrov! Yog tsis muaj lub suab nrov koj yuav hnov suab paj nruag tawm ntawm cov neeg hais lus. Ntawm no kuv yuav qhia koj yuav ua li cas thiaj ua rau koj tus kheej hais lus stero nrog kev ua kom nrov nrov!

Kauj Ruam 1: Sau Cov Khoom

Sau Cov Khoom

Nov yog cov ntaub ntawv siv:

Lub thawv ntawv ntawv - siv ua lub tsev hais lus, koj tuaj yeem xaiv qee yam muaj kuab heev Drill cov khoom - siv los laum qee qhov Ob tus neeg hais lus - Kuv tau xaiv ib khub ntawm 8 ohm ib leeg nyob ib puag ncig Cov cuab yeej siv Soldering Kub kua nplaum Ntawm no yog ntu rau lub tshuab hluav taws xob txuas: 1x protoboard 1x TDA2822M amplifier IC 2x 100uF capacitors 2x 470uF capacitors 2x 0.1uF capacitors 2x10K ohm resistors 2x 4.7 ohm resistors (Kuv siv 3.3K thiab nws ua haujlwm tau zoo) IC socket Misc. txuas

Kauj ruam 2: Tsim Circuit Court

Cov kauj ruam tom ntej yog tsim kom muaj qhov Circuit Court. Kuv siv TDA2822M lub tshuab ua kom nrov nrov thiab cov duab qhia hauv nws cov ntaub ntawv. Koj tuaj yeem xaiv los tsim koj lub Circuit Court nrog txhua lub tshuab hluav taws xob IC koj xaiv.

Kauj Ruam 3: Txhim Kho Qhov Ruaj Ntseg thiab Nruab Cov Hais Lus

Ua kom lub qhov rooj kaw thiab teeb tsa cov neeg hais lus

Tam sim no, muab tso ua ke qhov thaiv uas koj xav tau. Kuv tab tom tawm mus pw hav zoov rau 3 lub lis piam tom ntej, yog li kuv maj nrawm thiab xaiv qhov no … lub thawv ntawv thawv!

Tom ntej no kuv siv cov kua nplaum kub los lo rau ob tus neeg hais lus hauv.

Kauj Ruam 4: Xeem

Kuaj
Kuaj

Koj yuav tsum ua kom ntseeg tau tias koj tau sib sau txhua yam kom raug. Yog li sim tawm cov neeg hais lus!

Cov amplifiers yuav ua haujlwm txog qhov hluav taws xob ntawm 18v. Txog kev sim kuv txuas lub roj teeb me me 4.8 volt.

Kauj ruam 5: Muab tso ua ke

Tam sim no nws ua haujlwm, muab tso ua ke. Kuv siv cov kua nplaum kub thiab ob daim nplaum ua daim kab xev kom tso txhua yam ua ke.

Kuv siv lub laum me ntsis txhawm rau txhawm rau lub suab rau hauv. Kuv hloov pauv lub zog rau 6 AA roj teeb nyob rau hauv, yog li ntawm lub chaw pw hav zoov kuv tsuas tuaj yeem hloov AAs es tsis txhob nqa lub roj teeb.

Kauj Ruam 6: Laum Qhov Qhov

Laum Qhov Qhov
Laum Qhov Qhov

Kuv tsis yog tus kws tshaj lij suab, tab sis koj xav tau lub qhov ntawm koj lub tshuab hais lus kom tso cua tawm.

Kauj Ruam 7: Ntxiv Hauv Qab

Ntxiv Hauv Qab
Ntxiv Hauv Qab

Thaum kawg, kuv ntxiv daim duab los hauv qab.

Kauj ruam 8: Ua tiav

Ua tiav!
Ua tiav!

Koj ua tiav!
