Nrhiav kev txhim khu kev qha 2 nti tag nrho cov neeg hais lus tsav tsheb rau koj cov khoom lag luam? Koj nyob qhov twg lawm. Phau ntawv qhia no rhuav tshem txhua yam uas koj xav paub-los ntawm impedance piv rau kev tuav fais fab- kom koj tuaj yeem muaj kev ntseeg siab.
XDEC (Shenzhen Xuanda Electronics)tau tsim cov neeg hais lus tsav tsheb txij li xyoo 2009-17 xyoo ntawm tes- ntawm kev paub. Peb tuav ISO9001: 2015, IATF16949, thiab TUV ntawv pov thawj. Peb tus qauv MOQ yog 3,000 pcs nrog 3-5 hnub ua haujlwm rau cov khoom hauv Tshuag. Kev cai specifications yuav siv sij hawm 15-20 hnub. Peb teb cov lus nug hauv 24 teev thiab muab cov ntaub ntawv tshuaj xyuas hauv 48 teev.
Yog vim li cas 2 nti hais lus tsav tsheb yog ib qho kev xaiv ntse
Ib tug Φ50mm (2 nti) hais lus tsav tsheb hits qhov chaw qab zib ntawm compact loj thiab dlej bass tso zis. F0 resonance feem ntau tsaws nyob ib ncig ntawm 300-350Hz, muab rau koj siv tau qis-kawg mus rau 100Hz thaum ua ke nrog lub kaw lus tsim nyog. Qhov ntawd yog qhov txaus rau lub suab meej thiab nruab nrab yam tsis xav tau ib lub subwoofer cais.
Feem ntau 2 nti tsav tsheb tuav 3-10W RMS yooj yim. Lawv nrov nyob rau hauv cov neeg hais lus ntse, soundbars, desktop tham, thiab portable audio devices. Daim ntawv foos yog standardized txaus uas cov nqi cuab yeej nyob qis rau kev cai integrations.
Cov ntsiab lus tseem ceeb Koj tsis tuaj yeem tsis quav ntsej
| Parameter | Hom kab mob | Vim Li Cas Nws Tseem Ceeb |
|---|---|---|
| Impedance | 4Ω / 8Ω | 4Ω kos tam sim no ntau dua; phim koj lub amplifier |
| Rated zog | 3-10 W RMS | Tsis txhob ntau tshaj -kev pheej hmoo puas tsuaj |
| rhiab heev | 82-90dB | Siab dua=nrov dua ib watt |
| F0 | 280-380Hz | Tsawg dua=bass thaj tsam muaj peev xwm |
| Ntau zaus | F0-20kHz | Full -ntau yam npog cov suab zoo |
Impedance: 4Ω vs 8Ω - Koj Puas Xav Tau?
Nov yog txoj cai ntawm tus ntiv tes xoo: yog tias koj lub amplifier yog Class D (feem ntau hauv roj teeb -powered devices), mus nrog 4Ω kom ua tau zoo dua. Yog tias koj tab tom khiav ib txwm Class AB amp, 8Ω muab rau koj ntau lub taub hau thiab cua sov tsawg.
Ib qho yuam kev feem ntau yog ua ke tus tsav tsheb 4Ω nrog 8Ω- ntsuas amp- tam sim no kos ob npaug, thiab koj yuav raug txiav lossis puas tsuaj. Nco ntsoov xyuas koj lub amp qhov ntsuas qhov tsawg kawg nkaus ua ntej qhia.
Kev tuav fais fab: RMS vs Max
Cov neeg tsim khoom feem ntau sau ob qhov kev ntsuas hluav taws xob: RMS (nruam) thiab MAX (nruab nrab). Rau kev ntseeg siab ntev - lub sijhawm ua haujlwm, tsim koj lub cev nyob ib ncig ntawm RMS daim duab nrog 20% kev nyab xeeb. Tus neeg tsav tsheb ntsuas ntawm 5W RMS yuav tsum pom tsis pub ntau tshaj 4W hauv kev siv tiag.
Cov qhab nia siab tshaj yog raws nraim uas - luv luv rau cov neeg nyob ib ntus. Kev ua si txhawb nqa ntawm MAX lub zog yuav ua rau koj lub suab coil hauv lub lis piam, tsis yog hli.
Enclosure Design: Vim Li Cas Nws Ua lossis Ua Haujlwm Ua Haujlwm
Ib tus neeg tsav tsheb 2 nti xav tau tsawg kawg yog 0.1-0.2 litres ntawm ntim ntim kom ncav cuag nws lub peev xwm F0. Cov ntaub thaiv npog muab rau koj nruj dua bass thaj tsam; ported designs tuaj yeem thawb cov lus teb zoo dua lwm qhov octave qis dua tab sis yuav tsum tau kho qhov tseeb.
Yog hais tias koj tshiab rau enclosure tsim, pib nrog lub thawv kaw. Nws zam txim rau- dhau- qhov loj me tsuas yog dov tawm qhov siab, lawv tsis ua kom puas bass thaj tsam. Ported designs xav tau kev xam: qhov chaw nres nkoj txoj kab uas hla thiab ntev yuav tsum phim tus tsav tsheb F0 rau lub hom phiaj -3dB point.
Quality Indicators: Dab tsi cais Zoo los ntawm Pheej yig
| Yam Khoom Zoo | Tus Tsav Tsheb Zoo | Nyiaj txiag tsav tsheb |
|---|---|---|
| Lub Suab Coil | Copper, Ntau dua lossis sib npaug li 25mm txoj kab uas hla | Aluminium, me me |
| Magnet | Ferrite Ntau dua lossis sib npaug li 40mm lossis NdFeB | Me me ferrite |
| Ib puag ncig | Roj hmab los yog ntaub | Ua npuas ncauj (degrades ceev) |
| Bobbin | Kapton los yog aluminium | Daim ntawv (kub txaus ntshai) |
| Pairing Tolerance | ± 1dB | ± 3dB los yog tsis qhia |
Rau lub tso suab tso suab, ib txwm qhia meej ± 1dB ua ke ua siab ntev. Txwv tsis pub, koj cov channel sab laug thiab sab xis yuav hnov cov suab sib txawv -ib qho tsis txaus ntseeg rau txhua yam khoom siv suab.
OEM / ODM: Dab tsi los nug koj tus neeg muag khoom
Thaum muab 2 nti hais lus tsav tsheb rau OEM tej yaam num, qhia meej cov ntsiab lus ua ntej:
Lub sij hawm xa tuaj: Txheem 3-5 hnub rau Tshuag; kev cai 15-20 hnub
MOQ: Feem ntau 3,000 pcs rau kev cai specs, 500 pcs rau tsav khiav
Qauv qauv: Koj puas tuaj yeem tau txais 5-10 qauv rau kev ntsuam xyuas?
Cov ntawv ceeb toom: Thov teb zaus, THD, thiab impedance nkhaus
Compatibility: Nug kom pom cov ntim ntim khoom
Feem ntau yuam kev kom zam
| yuam kev | Vim li cas thiaj muaj teeb meem | Kev daws |
|---|---|---|
| Tsis quav ntsej impedance | Tsis sib haum amp=suab tsis zoo los yog puas | Match 4Ω rau Class D, 8Ω rau Class AB |
| Khiav ntawm MAX zog | Lub suab coil burnout | Tsim ntawm 80% ntawm RMS ntsuas |
| Tsis muaj khub kam rau ua | Stereo tsis sib haum | Qhia meej ± 1dB rau lub tso suab |
| Hla hlawv- hauv kev sim | Kev ua tsis tiav thaum ntxov | Thov 48-teev cov ntaub ntawv hlawv |
FAQ: 2 Nti Full Range Speaker Drivers
Dab tsi yog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis rau 2 nti hais lus tsav tsheb?
Standard MOQ yog 3,000 pcs rau ntau lawm khiav. Cov neeg muag khoom feem ntau muab kev tsav tsheb khiav ntawm 500-1,000 pcs rau kev lees paub ua ntej tag nrho cov khoom.
Kev xa khoom ntev npaum li cas?
Hauv -cov khoom xa tuaj hauv 3-5 hnub ua haujlwm. Kev cai tshwj xeeb nrog cov impedance tshwj xeeb lossis kev xav tau rhiab heev feem ntau siv sijhawm 15-20 hnub rau kev tsim khoom.
Kuv puas tuaj yeem tau txais cov qauv ua ntej kev txiav txim ntau lawm?
Yog, thov 5-10 qauv rau kev ntsuam xyuas engineering. Cov nqi coj mus kuaj feem ntau yog rov qab los ntawm thawj qhov kev txiav txim ntau lawm.
Dab tsi yog lub neej ntev ntawm 2 nti hais lus tsav tsheb?
Nrog rau kev siv kom raug (nyob rau hauv lub zog ntsuas, tsim nyog enclosure), cia siab tias 5-10 xyoo ntawm kev lag luam txhim khu kev qha. Over-powering los yog thermal stress shortens qhov no ho.
Kuv yuav ua li cas thiaj li ua tau zoo raws li kev txiav txim loj?
Qhia meej ± 1dB rhiab heev ua khub ua siab ntev thiab thov IQC cov ntaub ntawv. Tus neeg muag khoom zoo yuav muab cov ntaub ntawv xeem rau txhua pawg, suav nrog cov lus teb zaus.
