Nyob zoo txhua tus, yog li hauv cov lus qhia no kuv yuav qhia koj paub tias kuv tau ua qhov yooj yim boombox siv plywood los ntawm kev siv ob peb lub cuab yeej siv hluav taws xob. Kev tsim cov neeg hais lus nrog rau lwm qhov haujlwm me me uas kuv tuaj yeem siv tau hauv kuv lub neej niaj hnub muaj ib txwm yog kuv txoj kev mob siab rau thiab yam zoo li kev nyiam ua haujlwm ib yam. Peb txhua tus nyiam qhov kev xav uas peb tau txais thaum peb tau qhia rau lwm tus "Yog, Kuv tau ua qhov ntawd";-).

Yog li qhov no yog lub thawv tawg yooj yim tiag tiag uas tau ua los ntawm plywood thiab MDF board. Nws coj kuv 9 hnub los ua raws li kuv tsuas muaj cov cuab yeej txwv. Qhov no lub thawv ntim khoom muaj 4 tus hais lus - ob lub subwoofers thiab ob lub tweeters uas muab tag nrho ntawm 30 watts ntawm lub zog. Kuv tau siv 2 yam sib txawv ntawm tweeters- daim kab xev diaphragm ib yam li piezo hluav taws xob ib qho. Kuv txiav txim siab ua qhov no vim kuv pom tau tias piezo tweeter tau npog cov ntawv sau ntau zaus zoo dua li cov paj rwb diaphragm tweeter.

Lub boombox tau tsim nrog ob lub nraub qaum tig mus rau lub tshuab hluav taws xob passive. Lub tshuab hluav taws xob ua haujlwm hloov pauv rau cov chaw nres nkoj ntses bass thaj tsam. Lawv siv qhov chaw tsawg dua hauv qhov thaiv raws li piv rau cov chaw nres nkoj ntses bass thaj tsam thiab tiv thaiv qhov cua tawm suab nrov ib yam nkaus, tab sis qhov kuv nyiam txog lawv tshaj plaws yog kom pom lawv co thaum lub ntses bass thaj tsam tsoo uas ua rau tag nrho boombox zoo li txias dua;-).

Lub boombox khiav ntawm 12.6 volt, 3S 2600mah 18650 roj teeb pob uas muab sijhawm txog 6 teev ntawm kev ua si nyob ntawm qhov ntim.

Boombox txhawb FM, USB, bluetooth, SD, AUX thiab tseem los nrog IR cov chaw taws teeb thiab cov hais lus khawm kom yooj yim tswj suab paj nruag thiab kho dua.

Kuv xaj yuav luag txhua yam ntawm kuv cov khoom los ntawm AliExpress. Muaj feem ntau pheej yig dua nyob ntawd tab sis nws yuav siv sijhawm txog li ib hlis lossis ob hlis los txog ntawm koj qhov chaw raws li qhov chaw koj nyob.

1. YAMAHA TA2024 Amplifier X 1:

TA2024 yog chav kawm tshwj xeeb T amplifier. Thiab dab tsi tshwj xeeb txog class T amplifier yog tias nws muab ob qho tib si suab fidelity ntawm Class-AB thiab lub zog ua haujlwm ntawm Class-D amplifiers. Its a15 watts ib channel amplifier thaum nws ua haujlwm ntawm 4 hmo load. Kuv tau siv lub tshuab hluav taws xob no ua ntej ntawm lwm qhov haujlwm thiab tau txaus siab los ntawm qhov tseeb tias nws tsis sov li ntau dua li lwm lub tshuab hluav taws xob nrog cov lus qhia tshwj xeeb, yog li yog vim li cas kuv thiaj txiav txim siab siv lub amp rau txoj haujlwm no.

2. 3 nti, 15 watt sub Woofers X 2:

s.aliexpress.com/MvueueM7?fromSns

Nco ntsoov xaiv tus neeg hais lus uas nws qhov cuam tshuam nrog lub suab nrov uas koj siv kom koj tsis txhob ntsib teeb meem cua sov nrog lub suab nrov. Ntawm no kuv tau xaiv ib khub ntawm 3 nti, 4 ohms woofers uas raws li cov ntaub ntawv ntawm lub tshuab hluav taws xob yuav tsis zoo ntais ntawv.

3. DC-DC nqis nqis Buck converter X 1:

s.aliexpress.com/JfiaiIv2?fromSns

Qhov no yog tus qauv uas siv lub hauv paus ntsiab lus ntawm kev hloov pauv mus rau qhov muaj txiaj ntsig zoo. Peb txoj haujlwm xav tau nws vim tias peb siv lub roj teeb 12.6 volt rau lub zog 5volt audio decoder.

4. Passive radiators (60X90mm) X 2

s.aliexpress.com/fUJf2uQZ?fromSns

Passive radiators yog qhov hloov pauv rau qhov chaw ntsaws lossis ntses bass thaj tsam. Feem ntau rau cov ntaub thaiv me me, tsim kom muaj qhov tsawg zaus yuav tsum muaj chaw nres nkoj ntev, yog li cov tshuab hluav taws xob passive tau siv hloov. Passive radiators kuj zam cov suab nrov ntws uas feem ntau tshwm sim hauv cov neeg hais lus thauj khoom. ntawm cov phaj hlau ntawm lub tshuab hluav taws xob. Qhov loj yuav tsum tau sib txawv rau kev kho. Thaum siv cov woofers, ib txwm sim mus rau lub tshuab hluav taws xob passive uas yog qhov loj me lossis loj dua tus hais lus (tsis loj heev). Hauv qhov haujlwm no kuv tau xaiv ib lub tshuab hluav taws xob hla uas kuv tau txiav txim siab tso rau sab nraum qab ntawm boombox.

5. 3S 12V 18650 10A BMS X 1

s.aliexpress.com/M3Y77rIB?fromSns

BMS (Kev Tswj Xyuas Roj Teeb) yog ib qho tseem ceeb heev thaum txuas cov roj teeb uas tau them rov ua dua tshiab. BMS kuj txwv qhov siab tshaj plaws tam sim no uas tuaj yeem rub los ntawm lub roj teeb kom lub xovtooj tsis tuaj yeem ua haujlwm ntau dhau.

6. Zaus Crossover X 2:

s.aliexpress.com/jyYB3IRz?fromSns

Crossover feem ntau muaj Inductor (tooj liab kauj) ntawm cov xov hlau tuab thiab cov kab hluav taws xob ua ntu zus. Cov inductor thaiv qhov ntau zaus. Qhov tso tawm los ntawm tus inductor tau muab rau lub subwoofers. Tus capacitor thaiv qhov tsawg zaus. Yog li qhov tso zis ntau zaus los ntawm lub capacitor tau muab rau cov tweeters. Qhov tweeters tuaj yeem tawg yog tias cov zis los ntawm lub tshuab hluav taws xob txuas ncaj qha mus rau lub tweeters tsis muaj theem capacitor.
