Wb txiav mus caum. Nov yog 3 cov txheej txheem tseem ceeb rau kev xaiv cov neeg hais lus tsis sib haum xeeb rau cov neeg hais lus sab nraum zoov. Nco ntsoov cov no, thiab koj yuav lim tawm yam tsawg 80% ntawm cov neeg muag khoom tsis ntseeg siab.
1. Txheeb xyuas qhov ntsuas dej tsis zoo - IP67 Daim ntawv lo tsis txaus
Ntau tus neeg yuav khoom xav tias ntev npaum li tus neeg hais lus tsis sib haum xeeb tau sau npe IP67, nws zoo. Hauv kev muaj tiag, rau tib qhov kev ntsuam xyuas IP67, qhov sib txawv ntawm cov tuam txhab tsim khoom loj heev.
Muaj 3 hom kev ntsuas IP67 rau cov neeg hais lus tsis sib haum xeeb:
Laboratory Static Test: Muab tus neeg hais lus tso rau hauv 1 meter dej tob rau 30 feeb. Qhov no yog qhov kev sim yooj yim tshaj plaws, thiab cov tuam ntxhab feem ntau tuaj yeem dhau nws.
Simulated Rainfall Test: Txau dej los ntawm txhua lub ces kaum uas siv lub nozzle, yuav tsum tsis txhob cuam tshuam rau pem hauv ntej ntawm tus neeg hais lus tsav tsheb.
Kev Xeem Siv Qhov Tseeb: Nruab tus neeg hais lus tsav tsheb rau hauv lub thawv hais lus thiab kuaj cov dej tsis zoo hauv cov khoom siv tiag tiag. Qhov no yog qhov nruj tshaj plaws tab sis feem ntau cuam tshuam ntawm qhov zoo.
Ntawm Xuanda Electronics (XDEC), txhua pawg ntawm cov neeg hais lus tsis sib haum xeeb yog kuaj hauv cov khoom siv tiag tiag ua ntej xa khoom, tsis yog cov ntawv ceeb toom xwb. Nrog 17 xyoo nyob rau hauv kev lag luam electroacoustic, peb paub: zoo li qub IP67 cov ntaub ntawv ≠ dej tsis zoo.
| Txoj Kev Xeem | Nyuaj | Tswv yim nqi | Yuav ua li cas kom tsis txhob Pitfalls |
|---|---|---|---|
| Laboratory Static Test | ⭐ | Tsawg | Thov cov ntaub ntawv pov thawj ntawm cov khoom siv tiag tiag |
| Simulated Rainfall Test | ⭐⭐⭐ | Nruab nrab | Nug txog kev ntsuas dej siab thiab cov ces kaum |
| Kev Xeem Siv Qhov Tseeb | ⭐⭐⭐⭐⭐ | Siab | Xaiv cov chaw tsim khoom nrog hom ntawv tshaj tawm no |
2. Kos Lub Hwj Huam Hauv Pem Hauv Ntej - Pem Hauv Ntej Waterproof tsuas yog tsis txaus
Muaj lub ntsiab lus tseem ceeb uas ntau tus neeg saib xyuas rau cov neeg hais lus tsis sib haum xeeb uas siv rau hauv cov neeg hais lus sab nraum zoov: rear sealing.
Lub hauv paus ntsiab lus ua haujlwm ntawm cov neeg hais lus sab nraum zoov: lub diaphragm pem hauv ntej ua suab nrov, lub suab nrov tom qab vibrates. Yog tias lub nraub qaum tsis raug kaw, noo noo yuav nkag mus rau hauv PCB pawg thawj coj saib thiab cov pob qij txha, ua rau:
Kev sib koom tes oxidation, kev sib cuag tsis zoo
Lub suab coil xeb, ua kom luv luv lifespan
PCB luv Circuit Court, ua tsis tiav
Cov neeg tsim khoom uas tau ua tiav cov haujlwm hais lus sab nraum zoov yuav qhia rau koj: cov neeg hais lus sab nraum zoov yuav tsum muaj "pem hauv ntej + nram qab" dual sealing. Tsuas yog sau npe IP67, pem hauv ntej tsis muaj dej tab sis rov qab dej nkag - teeb meem yuav tshwm sim hauv 6 lub hlis.
💡 Tswv yim tswv yim:Nug tus neeg muag khoom rau tus ntoo khaub lig- kab kos duab ntawm tus neeg hais lus tsis muaj dej kom pom seb lub nraub qaum puas muaj kev kho dej tsis zoo (potting, txheej, thiab lwm yam). Yog tias tsis muaj qhov rov qab sealing, txawm tias tus nqi pheej yig npaum li cas, tsis txhob xaiv nws.
3. Match Impedance & Lub Hwj Chim - Lub zog loj dua tsis yog ib txwm zoo dua
Rau Φ77mm waterproof hais lus tsav tsheb siv nyob rau hauv sab nraum zoov hais lus, ntau lub zog ntau yam yog 3W-8W, nrog impedance xaiv ntawm 4Ω, 6Ω, thiab 8Ω.
Xaiv lub zog thiab impedance yuav tsum yog nyob ntawm koj lub amplifier nti:
| Amplifier tso zis | Pom zoo Tsav Tsheb Impedance | Pom zoo tsav lub zog | Yuav ua li cas kom tsis txhob Pitfalls |
|---|---|---|---|
| 4Ω / 3W amplifier | 4Ω | 3-5W | Tsis txhob xaiv 8Ω - nws yuav tsis tsav zoo |
| 6Ω / 5W amplifier | 6Ω | 5-8W | Impedance yuav tsum sib npaug |
| 8Ω / 8W amplifier | 8Ω | 8-10W | Khaws 20% lub zog lub taub hau |
Ib qho pitfall: cov neeg yuav khoom xav tias lub zog loj dua yog qhov zoo dua, xaiv tus tsav tsheb hais lus 15W nrog 5W amplifier. Qhov tshwm sim? Amplifier tsis tuaj yeem tsav nws tag nrho, ua rau lub ntim qis, distortion, thiab muaj peev xwm hlawv tus neeg hais lus tsav tsheb.
Xuanda Electronics (XDEC) tau ua haujlwm rau ntau tus neeg siv khoom nyob rau sab nraum zoov hais lus tsis siv neeg tsav tsheb. Peb qhov kev paub dhau los: lub zog ntawm 80% -100% ntawm lub tshuab hluav taws xob tso tawm lub peev xwm yog qhov zoo tshaj plaws - tawm hauv ib lub taub hau tab sis tsis txhob overdo nws.
4. Peb tus qauv rau kev txiav txim yog tias tus neeg hais lus tsis muaj dej tsis sib haum yog tus neeg muag khoom muaj kev ntseeg siab
Tom qab tag nrho cov lus qhia, ntawm no yog 3 cov txheej txheem ceev los txiav txim yog tias tus neeg muag khoom ntseeg tau:
Lawv puas yuav muab cov qauv rau kev sim tiag: Cov tuam txhab ntseeg siab tau txaus siab muab cov qauv rau kev sim. Cov uas hais tias "cov qauv yuav tsum tau them nyiaj" lossis "npaj koj tus kheej cov cuab yeej kuaj" yeej tsis xav kom koj sim.
Lawv puas yuav kos npe rau daim ntawv cog lus zoo: suav nrog kev cog lus tsis raug dej tsis zoo (tus qauv kev lag luam Tsawg dua lossis sib npaug li 1%), kev xa khoom ncua sij hawm them nqi. Yog tsis muaj kev pom zoo zoo, txhua qhov kev pheej hmoo yog nyob ntawm koj sab.
Lawv puas muaj cov xwm txheej sab nraum zoov: Nug tus neeg muag khoom rau cov neeg hais lus sab nraum zoov cov neeg siv khoom lawv tau ua, nyiam dua rau kev xa tawm mus rau European thiab Asmeskas kev lag luam. Cov kev lag luam no muaj kev txwv tsis pub muaj dej tsis zoo - dhau lawv cov ntawv pov thawj txhais tau tias muaj txiaj ntsig zoo dua.
💡 Txoj kev tshuaj ntsuam ceev:Nug tus neeg muag khoom rau patents thiab cov ntawv pov thawj xa tawm (CE, RoHS, thiab lwm yam) rau lawv cov neeg tsav tsheb sab nraum zoov tsis muaj dej tsis zoo. Muaj cov ntawv pov thawj tsawg kawg qhia tau tias lawv tau nqis peev hauv pawg no, tsis yog ua haujlwm OEM nkaus xwb.
5. FAQ – Cov lus nug
Q1: Rau cov neeg hais lus sab nraum zoov, puas yog IP67 lossis IP66 txaus rau cov neeg hais lus tsis sib haum?
A: Nws nyob ntawm koj qhov kev siv scenario. Rau kev mus pw hav zoov sab nraum zoov, siv pas dej da dej, IP66 yog qhov yooj yim txaus (kev tiv thaiv cov dav hlau dej muaj zog). Rau kev siv seaside, ntev - lub hnub thiab nag raug, nws raug nquahu kom mus ncaj qha nrog IP67. Kev ntsuas IP67 yog nruj dua: tsis muaj dej nkag thaum submerged hauv 1 meter dej rau 30 feeb.
Q2: Dab tsi yog lub neej ntev ntawm cov neeg hais lus tsis sib haum xeeb?
A: Cov neeg tsav tsheb tsis muaj dej tsis zoo los ntawm cov tuam txhab muaj npe tuaj yeem nyob tau 5+ xyoo nyob rau hauv kev siv ib txwm siv (tsis txhob txhob txwm tso dej los yog raug kub). Txawm li cas los xij, kev ua haujlwm tsis muaj dej tsis zoo yuav degrade thaum lub sijhawm. Nws tau pom zoo kom muab 2-xyoo lav tsis muaj dej tsis zoo rau cov khoom siv hais lus sab nraum zoov thiab hloov cov neeg hais lus tsav tsheb thaum lub sijhawm lav.
Q3: Vim li cas cov neeg hais lus tsis muaj dej tsis muaj zog ntau dua li cov khoom siv niaj hnub?
A: Waterproof hais lus tsav tsheb muaj 3 nqi ntxiv: ① Waterproof membrane cov ntaub ntawv ( breathable tab sis waterproof zaj duab xis, ntxiv ~ 15% nqi); ② Cov txheej txheem rov qab sealing (potting lossis txheej, ntxiv ~ 10% tus nqi); ③ Cov txheej txheem ntsuas dej tsis zoo (txhua chav yuav tsum tau sim, ntxiv ~ 5% tus nqi). Zuag qhia tag nrho, cov neeg tsav tsheb hais lus tsis muaj dej yog 30% -50% kim dua li cov khoom siv li niaj zaus.
Q4: Yuav ua li cas tswj qhov sib xws ntawm cov neeg hais lus tsis sib haum xeeb thaum lub sijhawm tsim khoom loj?
A: Qhov tseem ceeb yog xav kom tus neeg muag khoom muab 100% cov ntaub ntawv soj ntsuam, tsis yog cov ntaub ntawv qhia ua piv txwv xwb. Rau cov tuam txhab lag luam zoo, txhua tus neeg tsav tsheb hais lus tsis muaj dej tau sim ua ntej xa khoom xa tuaj (kev tshuaj ntsuam xyuas tag nrho) - kev kuaj xyuas tsis zoo. Tsis tas li ntawd, ua ntej muab qhov kev txiav txim, paub meej tias: ① Cov khoom lag luam tsis raug nqi cog lus Tsawg dua lossis sib npaug li 1%; ② Ua cov ntawv pov thawj me me (100-200 teeb) ua ntej ua ntej ntau lawm.
Q5: Lub sij hawm xa khoom zoo li cas rau cov neeg hais lus tsis sib haum xeeb?
A: Cov khoom lag luam txheem: 7-15 hnub, kev cai hais lus tsis muaj dej tsis sib haum: 30-45 hnub (nrog rau cov cuab yeej, ntsuas dej tsis zoo). Yog tias tus neeg muag khoom hais tias "tus neeg hais lus tsis muaj dej tsis zoo hauv cov khoom lag luam," yuav tsum ceev faj - cov neeg tsav tsheb hais lus tsis muaj dej muaj lub neej txee, thiab khaws cia ntev dhau los yuav cuam tshuam rau kev ua haujlwm tsis zoo.
