Φ50mm sab nraud magnet hais lus tsav tsheb rau soundbar thiab desktop saib
1. Vim li cas Soundbar Engineers xav tau daim ntawv teev npe tshwj xeeb rau Φ50mm Sab Nraud Magnet Tsav Tsheb
A Φ50mm sab nraud hlau nplaum 4 nti tsav tsheb feem ntau khiav 4Ω, 15W, F0 80Hz, 88dB rhiab heev. Hauv soundbar qhov no yog "mid-bass channel" - tuav 80Hz txog 500Hz rau suab thiab seev. Tab sis sab nraud hlau nplaum topology muaj ib qho kev pheej hmoo uas cov hlau nplaum sab hauv (Y hom) tsav tsheb tsis: sib nqus nqus.
Magnetic to tsis yog ib qho kev txhawj xeeb. Φ50mm sab nraud hlau nplaum chav tsev muaj flux ceev nyob ib ncig ntawm 0.8-1.2T, nrog stray teb ntawm 5-10mT tseem ntsuas 5-10cm los ntawm cov hlau nplaum thav duab (ib IEC 60404-8-1 magnetic tivthaiv ib puag ncig kuaj). Yog hais tias lub soundbar mainboard zaum ze dua 8cm, lub analog pem hauv ntej kawg yuav tuaj tos 50Hz hum.
Nyob rau sab nraud, cov tsav tsheb hlau nplaum sab nraud muaj lub zog loj dua lub taub hau thiab kev ua haujlwm zoo dua, uas yog vim li cas KTV chav, saib lub desktop, thiab kev lag luam PA tsim nyiam lawv - tsuav yog koj khaws "magnetic khaws- tawm tsam" nyob ib ncig ntawm tus neeg tsav tsheb. Tom qab 17 xyoo nyob rau hauv lub tshav pob, 8cm yog lub empirical cia - tawm deb; nrog ib daim thaiv hlau nplaum tuaj yeem poob mus rau 5cm, tab sis ntxiv 18% rau cov nqi tsev.
XDEC tau xa tawm 2000+ tus qauv tsav tsheb npog Φ3-Φ324mm, thiab Φ50mm sab nraud hlau nplaum yog ib qho ntawm cov neeg tsav tsheb sab saum toj hauv peb chav W. Peb tau ua hauj lwm nrog soundbar thiab saib xyuas hom nyob rau hauv lub teb chaws Yelemees, Nyiv, Kauslim, thiab US. Ob qhov kev teeb tsa sab nraud sab nraud: 4Ω 15W "tus qauv hlau nplaum sab nraud" thiab 4Ω 25W "siab zog sab nraud hlau nplaum". Cov tom kawg siv cov hlau nplaum loj dua nrog qhov dav dua qhov xau tab sis cov lus teb zoo dua.
2. Desktop Monitor: F0 80Hz Tsav Tsheb, Lub Txee Loj Dab Tsi Koj Xav Tau?
F0 80Hz yog tus nqi raug rau Φ50mm sab nraud hlau nplaum tsav tsheb (kev lag luam ntau yam 63-200Hz, 4 nti thoob 80-120Hz). Tab sis F0 yog qhov ntsuas huab cua dawb. Ib zaug mounted rau hauv ib lub txee, tsis tshua muaj zaus extension hloov: kaw txee mus txog ~ 1.4x ntxaum, ported txee mus txog 1.7-2.0x ntxaum.
Ntawm no yog engineering siv rau desktop saib scenarios:
<>Subwoofer txee

| Ported txee | 5-8L | ~ 50-60Hz | Desktop HiFi / Soundbar |
| 10-15L | ~ 45 Hz | Compact pem teb saib |
Nco tseg: cov no yog qhov tseem ceeb, tsis yog cov ntaub ntawv cog lus. Qhov tseeb txuas ntxiv kuj nyob ntawm qhov chaw nres nkoj ntev, cov khoom siv damping, thiab tus neeg tsav tsheb rhiab heev kam rau ua. Ib qho yuam kev yogxaiv tus tsav tsheb ua ntej, ces tsim lub txee- qhov tshwm sim feem ntau suab av nkos txawm tias muaj kev tsav tsheb zoo heev.
3. KTV Chav thiab Kev Lag Luam PA: 4Ω lossis 8Ω rau Φ50mm Sab Nraud Magnet Tsav Tsheb?
Rau Φ50mm sab nraud hlau nplaum tsav tsheb, kev lag luam impedance faib yog 4Ω ntawm 75%, 8Ω ntawm 22%, lwm yam 3%. Qhov kev xaiv tsis yog "qhov twg zoo dua" - nws yog hais txog kev sib piv lub amplifier.
4Ω tsav: siab dua tam sim no, xav tau amplifier uas yuav ruaj khov tsav 4Ω loads (feem ntau Class-D amps xav tau 4-16Ω dav impedance txhawb). Hom rau desktop saib thiab nquag soundbar bass channel.
8Ω tsav: siab dua voltage, qis dua tam sim no, haum rau ntev -qhov deb tsis tu ncua-voltage PA systems (70V / 100V) lossis amps nrog kev tiv thaiv tsis muaj zog.
Hauv KTV chav teeb, 4Ω tsav tsheb ntau dua - yog vim li cas tib lub amp tuaj yeem tsav ntau chav nyob rau tib lub sijhawm (8Ω txhawb nqa 4 tus tsav tsheb sib npaug, 4Ω txhawb nqa tsuas yog 2). Tab sis 4Ω cov neeg tsav tsheb xav tau ntau dua los ntawm amp txias: ntawm 2 teev ntawm lub zog tas li, lub amp chassis kub nce 30-40 degree.
Rau desktop saib, ob qho tib si 4Ω thiab 8Ω muaj ntau nyob ntawm seb tus saib puas ua haujlwm (tsim- hauv amp, feem ntau 4Ω) lossis passive (sab nraud amp, feem ntau 8Ω). Ib lub txee- cov ntaub ntawv nkag siab los ntawm peb 17 xyoo: lub desktop saib hom hloov los ntawm 8Ω mus rau 4Ω tsav tsheb, pom tau tias kev txhim kho suab yog qhov tsawg heev tab sis amp tsis ua haujlwm tau dhia 22%, thiab lawv rov qab mus rau 8Ω.
4. Lub Suab Coil Cooling: Muaj pes tsawg Watts tuaj yeem ua tus Φ50mm Sab Nraud Magnet Tsav Tsheb Txhawb?
Lub thermal bottleneck rau Φ50mm sab nraud hlau nplaum tsav tsheb yog lub suab coil enameled hlau. Cov neeg tsav tsheb hlau nplaum sab nraud muaj txoj kev tshav kub ntev dua li cov hlau nplaum sab hauv (Y hom) tsav tsheb. Ntawm 15W ntsuas lub zog, txuas ntxiv 2-teev kev ua haujlwm thawb lub suab coil kub mus rau 60-70 degree; ntawm 20W nws nce mus rau 75-85 degree, nyob ze ntawm cov enamel txwv (feem ntau 130℃Class B lossis 180℃Class H).
Yuav ua li cas los txheeb xyuas hauv daim ntawv teev cov ntaub ntawv yog "load test" clause, tsis yog lub zog ntsuas:
"White suab nrov 15W 96 teev" → yam tsawg kawg nkaus hla kab, tiag- teeb meem hauv ntiaj teb yuav tshwm sim hauv 24 teev
"Sine yoj 15W 8 teev" → nruj dua lub suab nrov dawb, cov neeg tsav tsheb hla qhov no muaj zog dua
"+70℃24h cia + re-test SPL" → re-test SPL tom qab siab-temp cia, tsis yog kev kuaj pom xwb
Ntawm XDEC, peb 17- xyoo IQC tus qauv ua khub tsav tsheb rau ± 1.5dB kam rau ua (nruj dua li cov ntaub ntawv tsis raug ntawm ± 3dB), nrog 8M + cov khoom xa tawm ntawm cov kab lag luam tshaj tawm. Qhov kev zam nruj dua no yog dab tsi lub tso suab soundbar thiab dual-tsav duab saib xyuas cov haujlwm nug rau feem ntau.
