Kev hloov tus neeg hais lus tsav tsheb tsis nyuaj -nrhiav qhov yog, thiab koj tau teem sijhawm rau ob xyoos. Nrhiav qhov tsis ncaj ncees lawm, thiab koj yuav ntsib kev npau suav phem ua ntej koj paub nws.
Niaj hnub no, kuv tab tom rhuav tshem 5 qhov teeb meem feem ntau thaum hloov cov neeg muag khoom. Txheeb xyuas cov npe no, thiab koj yuav zam tsawg kawg 80% ntawm cov teeb meem.
1. Tsom ntsoov rau tus nqi, tsis quav ntsej Parameter Consistency
Qhov no yog qhov yuam kev tshaj plaws. Cov quotes tag nrho hais tias "Φ45mm 4Ω 5W", thiab lawv zoo tib yam rau ntawm daim ntawv. Tab sis thaum cov khoom tuaj txog:
rhiab heev yog 3dB tawm - ntim yog qhov qis dua
F0 (resonance zaus) txawv los ntawm kaum tawm Hz -bass kev ua tau zoo sib txawv kiag li
DC tsis kam sib txawv ua rau amplifier txuam teeb meem
XDEC (Shenzhen Xuanda Electronics) tau tshwj xeeb hauv kev hais lus tsav tsheb tsim rau 17 xyoo. Peb tau pom ntau tus neeg tau txais kev kub hnyiab los ntawm parameter inconsistency. Tus neeg muag khoom tsim nyog yuav tsum muab: cov lus teb cov lus qhia nkhaus rau txhua pawg, cov ntaub ntawv ntsuas qhov tseeb, thiab cov ntaub ntawv sib txawv ntawm qhov sib txawv.
| Xyuas yam khoom | Txais Tus Qauv | Standard zoo heev | Pitfall Avoidance |
|---|---|---|---|
| Sensitivity Deviation | ± 3dB | ± 1dB | Thov daim ntawv qhia kev xeem tiag los ntawm kev xa khoom kawg |
| F0 Deviation | ± 20Hz | ± 10Hz | Sib piv cov qauv vs loj ntau lawm tsis |
| Impedance Deviation | ±10% | ±5% | 4Ω tsav tsheb: 3.6-4.4Ω ntsuas tau txais |
2. Cov qauv dhau, Kev tsim khoom loj loj poob qis
Cov qauv koj kuaj tus kheej? Tsis muaj teeb meem. Tab sis thaum loj ntau lawm tuaj txog, lub suab yuav muffled thiab sib xws tsis zoo. Vim li cas?
Qhov teeb meem nyob rau hauv kev tswj ntau lawm. Nov yog qhov txawv ntawm cov chaw tsim khoom zoo thiab cov khoom tsis zoo:
Kev tshuaj xyuas tuaj: Puas yog lub suab coil winding nro zoo ib yam? Puas yog hlau nplaum them lub zog ruaj khov?
Kev sib dhos txheej txheem: Puas muaj cov qauv rau lub sijhawm kho cov nplaum, cov khoom sib koom ua ke zoo, thiab lub siab dome?
100% kuaj ua ntej shipping: Puas yog txhua chav kuaj sim, lossis tsuas yog 10% qhov chaw- kuaj?
Raws li tus kws tshaj lij hais lus tsav tsheb tsim khoom hauv Shenzhen, peb txoj hauv kev ntawm XDEC: 100% kev sim tag nrho rau txhua tus neeg hais lus tsav tsheb, nrog ib chav tsev tshaj ± 1dB sib txawv ntawm spec scrapped. Qhov no tsis yog hais txog tus nqi - nws yog hais txog cov neeg siv khoom ntseeg.
3. Kev Cog Lus Xa Khoom Zoo Zoo, Ntawm -Lub Sijhawm Kev Xa Khoom Sib txawv
Tus neeg muag khoom ntseeg siab hais tias "30 hnub xa khoom", tab sis tom qab ntawd:
Lub Limtiam 1: Cov khoom raug yuav
Lub Limtiam 2: Tseem tos cov hlau nplaum tuaj txog
Lub Limtiam 3: Cov kab ntau lawm overloaded, nyob rau hauv queue
Lub Limtiam 4: Thaum kawg xa tawm, tab sis 20% ploj ntawm kev txiav txim
Koj txoj kev npaj tsim khoom lag luam raug cuam tshuam, thiab koj tsis pom qhov muag muag zoo tshaj plaws. Qhov ntawd yog tus nqi tiag.
Yuav ua li cas kom tsis txhob muaj qhov teeb meem no?
Txheeb xyuas tus neeg muag khoom lub peev xwm txhua hli vs. koj qhov kev txiav txim kom muaj nuj nqis (kev txiav txim / peev> 50% yog qhov txaus ntshai)
Thov ntawm -cov ntaub ntawv tus nqi xa khoom raws sijhawm los ntawm 3 lub hlis dhau los
Qhia meej meej cov nqe lus them nqi xa tuaj lig hauv daim ntawv cog lus
4. Kev pab txhawb nqa poob qis, tsis muaj leej twg pab thaum muaj teeb meem tshwm sim
Thaum lub sij hawm me me -batch mus sib hais, tus neeg muag khoom tau mob siab rau. Tom qab ntau lawm, teeb meem tshwm sim tab sis tsis muaj leej twg teb hu lossis lus.
Cov neeg hais lus tsav tsheb yog ib nrab- cov khoom tiav- nws tsis yooj yim li tsuas yog txhim kho lawv. Cov teeb meem koj yuav ntsib:
Cavity tsim tawm tswv yim: Ntau npaum li cas rov qab kab noj hniav qhov chaw tus Φ45mm tsav tsheb xav tau?
Amplifier txuam: Yog tias lub amp tso tawm 4Ω, kuv puas tuaj yeem txuas tus tsav tsheb 8Ω?
Waterproofing: Yuav tsum tau sealing qib dab tsi rau sab nraum zoov Bluetooth hais lus?
Ib tus neeg muag khoom zoo muab kev txhawb nqa kev txhawb nqa. XDEC txoj hauv kev: txhua tus neeg siv khoom tau txais tus kws tshaj lij tshwj xeeb, nrog kev txhawb nqa tag nrho los ntawm kev xaiv los ntawm ntau lawm. Thaum muaj teeb meem tshwm sim, peb teb tsis pub dhau 24 teev.
5. Tsis kuaj Customization muaj peev xwm, xaus nrog cov khoom tsis raug
Koj tus hais lus Bluetooth yuav muaj cov cai tshwj xeeb:
Tshwj xeeb mounting qhov ntev (cov khoom pwm twb tau ua, hloov tsis tau)
Cov txheej txheem dej tsis txaus (IPX7 yuav tsum tau ua)
Qhov tshwj xeeb zaus teb nkhaus xav tau (ua raws li koj qhov DSP tuning)
Tab sis tus neeg muag khoom tsuas yog ua cov khoom txheem, nrog xoom customization muaj peev xwm. Koj raug yuam kom sib cuam tshuam cov khoom tsim lossis nrhiav tus neeg xa khoom tshiab.
Ua ntej xaiv tus neeg xa khoom, nco ntsoov qhia meej:
Lawv puas tuaj yeem muab qhov tsis yog - tus qauv hloov kho?
Lawv puas tuaj yeem ua tau raws li cov kev cai tshwj xeeb xws li kev tiv thaiv dej, tiv thaiv corrosion, lossis siab -kub tsis kam?
Qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi? (Yog tias lub Hoobkas xav tau 5,000 tab sis koj tsuas xav tau 2,000?)
Φ45mm Multimedia Speaker Tsav Parameter Siv
Nov yog ib qho kev siv rau Φ45mm multimedia hais lus tsav tsheb specifications rau koj xaiv:
| Parameter | Common Spec | Kev xaiv tswv yim |
|---|---|---|
| Loj | Φ45mm × 20-23mm qhov siab | Paub meej tias koj cov khoom kab noj hniav qhov tob yog txaus |
| Impedance | 4Ω / 6Ω / 8Ω | 4Ω yog feem ntau, ntais ntawv feem ntau Bluetooth amplifiers |
| Hwj chim | 3W / 5W / 8W | Tsis txhob tshaj qhov tso zis ntau tshaj amplifier |
| rhiab heev | 82-90dB | Siab txhais tau tias nrov dua, tab sis sib npaug nrog lub suab zoo |
| F0 | 150-250Hz | Tsawg txhais tau tias zoo dua bass, tab sis tus nqi siab dua |
| Daim ntawv thov | Ntse hais lus, Bluetooth hais lus, desktop suab | Paub meej tias tus neeg muag khoom muaj kev paub dhau los |
FAQ - Cov lus nug nquag
Q1: Dab tsi yog qhov txawv ntawm Φ45mm thiab Φ40mm hais lus tsav tsheb hauv Bluetooth tham?
Teb: Qhov ntau thiab tsawg feem ntau muab cov ntses bass thaj tsam zoo dua, tab sis kuj xav tau ntau qhov chaw kab noj hniav. Yog tias koj cov khoom hais lus me dua (<300ml), Φ40mm is more suitable; if space allows (>500ml), Φ45mm muab kev ua haujlwm tsawg dua - zaus.
Q2: Tom qab hloov cov chaw muag khoom, cov ntsuas tsis sib xws tab sis lub suab xav txawv. Vim li cas?
Teb: Cov nplooj ntawv Parameter tsuas yog qhia cov ntsiab lus yooj yim. Dab tsi cuam tshuam rau lub suab yog zaus teb nkhaus smoothness, harmonic distortion, thiab ib ntus teb. Tshaj li daim ntawv qhia tshwj xeeb, nug cov neeg muag khoom kom paub meej cov lus teb cov lus qhia kab lus, lossis ua cov kev ntsuam xyuas mloog nrog cov qauv.
Q3: Tus neeg muag khoom hais tias MOQ yog 5,000 units, tab sis kuv tsuas xav tau 2,000. Kuv yuav ua li cas?
Teb: Sib tham tus nqi sib tham nrog tus neeg muag khoom, lossis npaj cov khoom xa tuaj (xa 2,000 ua ntej, tshuav 3,000 dhau 3 lub hlis). Ntau lub tuam txhab hais lus tsav tsheb hauv Shenzhen muab cov lus MOQ hloov pauv tau- tus yuam sij yog nrhiav tus neeg muag khoom txaus siab koom tes.
Q4: Puas yog tus hais lus tsav tsheb rau Bluetooth hais lus xav tau kev tiv thaiv dej?
Teb: Nyob ntawm cov khoom muag. Sab nraum zoov Bluetooth hais lus yuav tsum muaj tsawg kawg yog IPX5 (txheej- tiv taus); siv ze cov pas dej da dej yuav tsum muaj IPX7 lossis siab dua. Cov neeg tsav tsheb tsis muaj dej tsis zoo xav tau txheej txheej ntawm lub diaphragm thiab pob tawb, ntxiv 10-15% rau cov nqi.
Q5: Yuav ua li cas txiav txim siab seb tus neeg hais lus tsav tsheb puas ntseeg tau?
Teb: Tshawb xyuas peb yam: ① Lawv puas muaj ISO9001 cov ntawv pov thawj zoo? ② Lawv puas kam muab cov qauv dawb rau kev kuaj? ③ Lawv puas ua 100% kev sim thiab muab cov ntawv ceeb toom nrog kev xa khoom? Yog tias tus neeg muag khoom tau ntsib tag nrho peb, tsawg kawg lawv mob siab rau lawv txoj kev lag luam.
