Lub suab muaj zog tsis tiav yog tsis muaj subwoofer. Tab sis hnyav thauj khoom tuaj yeem ua rau nws ua haujlwm tsis zoo. Muaj ntau ntau yam, tab sis tsuas yog ob peb daws teeb meem. Tab sis txhua tus neeg tuaj yeem kho nws, yog tias koj paub dab tsi thiab ntu twg koj yuav tsum tau ua.

Cov Lus Qhia
Kauj ruam 1
Pom tawm lub subwoofer. Yog tias cov neeg hais lus sib txuas rau nws tsis ua hauj lwm, tshawb xyuas cov xov tooj sib txuas rau kev tawg. Txheeb xyuas qhov sib txuas ntawm subwoofer thiab hais lus. Yog tias tsis muaj hluav taws xob, kuaj lub cable. Nrog kev pab ntawm tus simter, ntiv nplhaib txhua lub xov hlau, yog li koj tuaj yeem paub meej tias lawv nyob qis.
Kauj ruam 2
Disassemble rooj plaub. Txhawm rau ua li no, txiav tawm lub subwoofer los ntawm lub ntsiab thiab hais lus. Siv lub hau loj, tshem cov ntsia hlau tom qab ntawm lub rooj plaub. Ua tib zoo tshem tawm cov microcircuit phaj. Yog tias daim phaj tsis mus, tsis rub, koj tuaj yeem tsoo cov kab txuas uas txuas. Ci teeb nyem thiab pom qhov ua rau.
Kauj ruam 3
Ua tib zoo tshuaj xyuas cov microcircuit rau cov khoom hlawv. Kuj saib ntawm cov ciav hlau, tej zaum qee yam luv-circuited. Nco ntsoov ua qhov no hauv kev teeb pom kev zoo.
Kauj ruam 4
Kuaj cov fuses. Lawv sawv ntsug ntawm xub ntiag lub transformer. Yog tias lawv hlawv, tsuas yog hloov. Yog tias qhov teeb meem tseem txuas ntxiv thiab lawv nyob dua, tshawb xyuas lub voltage hauv lub network.
Kauj ruam 5
Kuaj seb puas muaj hluav taws xob nkag mus rau microcircuit. Txhawm rau ua li no, txiav tawm lub tshuab hloov hluav taws xob los ntawm lub ntsaws (qhov microcircuit) thiab txuas qhov sib npaug - lub teeb tsa hluav taws xob, piv txwv. Yog tias tsis muaj hluav taws xob los yog nws tsis yog ntawm tib txoj kev ntsuas raws li qhov xav tau rau kev khiav hauj lwm ib txwm ntawm microcircuit, nws yog qhov yuam kev.
Kauj Ruam 6
Kuaj cov zis hluav taws xob ntawm cov microcircuit. Yog li koj tuaj yeem nkag siab yog tias muaj teeb liab ntawm qhov tawm, thiab nws yog dab tsi. Raws li qhov no, kev kho kom zoo tom ntej ntawm lub microcircuit yuav muab xaus. Qhov no yog lub suab nrov ntawm diodes, resistors, thiab lwm yam. Yog tias tsim nyog, qee cov ntsiab lus yuav xav tau muab tshem tawm nrog lub hlau soldering rau lub suab. Tab sis tsis txhob hnov qab, siab dhau ib kub yuav ua rau lawv puas tsuaj, ua rau microcircuit nws tus kheej. Yog tias koj pom cov khoom tsis raug, hloov nws thiab ntsuas lub teeb liab tawm, yog tias qhov laj thawj tsis raug tshem tawm, txuas ntxiv mus saib rau qhov ua tsis zoo ntxiv.
Kauj Ruam 7
Txuas lub microcircuit rau rooj plaub thiab sib sau ua ke rau subwoofer.
