Tsis muaj fluff. Cia peb tham tshwj xeeb.
Thaum xaiv cov neeg tsav tsheb tsis muaj dej tsis zoo rau cov chaw them nyiaj EV sab nraum zoov, 90% ntawm kev ua tsis tiav los rau peb qhov teeb meem: kev ntsuas dej tsis txaus, lub zog tsis sib haum, lossis kev xaiv tsis raug. Niaj hnub no, XDEC-17 xyoo hauv kev tsim hluav taws xob hluav taws xob-tawg peb qhov teeb meem tseem ceeb no.
1. Vim li cas EV Charging Stations yuav tsum tau IP67+ Cov neeg hais lus tsis muaj dej
Cov chaw them nyiaj ua haujlwm sab nraum zoov thaum nag, plua plav, thiab kub heev. Standard IP54 tus neeg hais lus tsav tsheb kav ntev dua 6 lub hlis- noo noo degrades lub diaphragm, txo cov bass teb rau ze li ntawm tsis muaj dab tsi.
Plua plav yog qhov teeb meem sib npaug. Northern China's sandstorms sau IP54 tsav tsheb qhov khoob nrog cov khoom zoo, ua rau lub suab sib txhuam thaum ua haujlwm thiab muaj peev xwm hlawv tawm lub suab coil.
IP67 waterproof hais lus tsav tsheb zoo:
Ua tiav kev tiv thaiv plua plav- nyab xeeb rau qhov chaw muaj plua plav sab nraum zoov
Kev tiv thaiv dej immersion-30 feeb hauv dej nyab tsis muaj kev puas tsuaj
Dav kub kam rau ua: -30℃rau +80℃ruaj khov ua haujlwm
3x lub neej ua haujlwm ntev dua piv rau cov qauv tsav tsheb
2. Φ50mm Waterproof Speaker Driver Parameters rau EV Charging Stations
EV charging chaw nres tsheb suab tshuab tsom rau lub suab ceeb toom thiab tshaj tawm xwm txheej. Cov kev xav tau ntawm lub zog yog me me, tab sis lub suab meej yog qhov tseem ceeb. Ntawm no yog cov tseem ceeb xaiv parameter:
| Parameter | Yam tsawg kawg nkaus | Hwm Standard | Zam cov no |
|---|---|---|---|
| Kev tiv thaiv ntsuas | IP65 | IP67 / IP68 | Hauv qab IP65 tsis haum rau sab nraum zoov |
| Loj | Φ40-50mm | Φ50 hli | Loj dhau yuav tsis haum; me me dhau tsis muaj ntim |
| Kev ntsuas fais fab | 4-8W | 8-10W | Lub zog siab ua rau muaj kev cuam tshuam hauv cov ntaub ntawv me me |
| Impedance | 4Ω lub 8Ω | 4Ω | 4Ω ncaj qha tsav amp yooj yim nrog ntim zoo dua |
| rhiab heev | Ntau dua lossis sib npaug li 85dB | Ntau dua lossis sib npaug li 90dB | Tsawg rhiab heev ua tsis tau nyob rau sab nraum zoov |
| Ntau zaus | 500Hz-8kHz | 300Hz-10kHz | Lub suab tshaj tawm tsom rau nruab nrab zaus |
| Kev khiav hauj lwm Temp | -20℃~ +60 degree | -30℃~ +80 degree | Cov chaw them nqi mus txog 70℃+ nyob rau lub caij ntuj sov tshav ntuj |
💡 Cov lus qhia xaiv: Ua ntej IP67+ nrog rhiab heev dua lossis sib npaug ntawm 90dB thiab kev khiav haujlwm ntau -30℃~+80℃. Φ50mm yog qhov zoo tshaj plaws match rau them chaw nres tsheb daim ntaub ntawv.
3. Ob Qhov Teeb Meem Tsis Txaus Siab rau EV Charging Station Speaker Drivers
XDEC tau ua haujlwm ntau ntau ntawm EV chaw nres tsheb cov neeg siv khoom. 90% ntawm cov teeb meem rov ua haujlwm yog los ntawm kev teeb tsa:
Qhov yuam kev 1: Tsis muaj kev tiv thaiv theem ob ntawm Mounting Point
Qee tus neeg yuav khoom xav tias IP67 hais lus tsav tsheb txhais tau tias muaj kev tiv thaiv tiav. Txawm li cas los xij, thaum drilling mounting qhov, qhov sib txawv ntawm tus neeg tsav tsheb thiab chassis yuav tsum tau muab kaw nrog cov dej tsis zoo. Ntau lub Hoobkas muab tus neeg tsav tsheb tsis ceeb toom koj txog qhov no.
Txoj hauv kev kom raug: Siv cov dej tsis zoo silicone gasket rau ntawm qhov chaw mounting, siv cov ntsia hlau tsis muaj dej rau lub qhov mounting, thiab cov khoom siv dej tsis zoo rau cov hlau tawm. Tag nrho peb kauj ruam yog yuav tsum tau.
yuam kev 2: Amplifier tso zis fais fab tsis sib haum
EV charging chaw nres tsheb amplifier chips feem ntau tso tawm 1.5-2x tus neeg hais lus tsav lub zog ntsuas. Yog hais tias amp outputs 20W tab sis hais lus tsuas yog 8W rated, sustained high-volume playback yuav hlawv tawm tus tsav tsheb.
Hloov pauv, yog tias amp tso zis tsuas yog 5W tab sis tus neeg hais lus yog 15W ntsuas, lub suab yuav nyob ntsiag to heev rau lub suab kom nrov.
Pom zoo: Amplifier tso zis=Hais lus ntsuas lub zog × 1.2 ~ 1.5. Qhov no yog qhov kev nyab xeeb tshaj qhov sib piv.
4. Peb tus qauv txhawm rau txheeb xyuas tus neeg muab khoom ntseeg tau
Thaum nrhiav cov neeg tsav tsheb tsis muaj dej tsis zoo rau cov chaw them nyiaj EV, qhov kev pheej hmoo loj tshaj plaws yog "cov qauv OK, cov khoom loj tsis ua haujlwm." Nov yog XDEC tus qauv tshuaj ntsuam xyuas tus neeg xa khoom:
1. Thov daim ntawv pov thawj tiv thaiv
Qhov tseeb IP67 tus neeg hais lus tsav tsheb tuaj nrog thib peb-cov ntaub ntawv kuaj xyuas tog uas qhia txog kev sim (dej qhov tob 1 meter, ntev 30 feeb). Yog tias cov neeg muag khoom tsuas tuaj yeem muab cov ntawv tshwj xeeb yam tsis muaj ntawv ceeb toom, lawv cov ntaub ntawv tiv thaiv yuav raug nug.
2. Tshawb xyuas Kev Tswj Xyuas Zoo
Thov batch cov ntaub ntawv soj ntsuam tuaj. Tsom ntsoov rau qhov sib txawv rhiab heev. Cov neeg tsav tsheb zoo tswj kev nkag siab tsis pub dhau ± 2dB; Yog hais tias sib txawv tshaj ± 5dB, lawv cov kev tswj zoo tsis ruaj khov.
3. Paub meej tias lub sij hawm ua ntej thiab MOQ
EV charging chaw nres tsheb tej yaam num feem ntau pib nrog 500-1000 units rau thawj validation. Yog tias tus neeg muag khoom MOQ pib ntawm 5000 units, koj tsis muaj lub zog sib tham thaum lub sij hawm ua pov thawj me me. Qhia meej cov sij hawm ua ntej (piv txwv 7 hnub, ntau lawm 30 hnub yog cov voj voog tsim nyog).
5. Cov lus nug FAQ
Q1: 4Ω lossis 8Ω hais lus tsav tsheb rau EV them chaw nres tsheb?
Teb: Nyob ntawm koj tus qauv amplifier. Yog tias amp outputs 4Ω, ua ntej 4Ω hais lus kom yooj yim sib piv thiab ntim zoo dua. Yog tias amp outputs 8Ω, xaiv 8Ω hais lus kom txo tau lub zog siv thiab tsim hluav taws xob. Kev sib xyaw ua rau lub zog tsis sib haum xeeb- txawm tias hlawv tus tsav tsheb lossis ntim tsis txaus.
Q2: Tus neeg hais lus IP67 puas tuaj yeem siv sijhawm ntev - tso dej?
Teb: IP67 yog "luv-kev tiv thaiv lub sijhawm," tsis yog "kev ua haujlwm hauv qab dej txuas ntxiv." Rau lub sijhawm ntev -submersion, xaiv IP68 nrog cov ntaub ntawv kuaj tus neeg xa khoom uas qhia txog 2-meter qhov tob hauv kev nkag mus. EV charging chaw nres tsheb yuav tsis dej nyab, yog li IP67 txaus.
Q3: Qhov twg yuav tsum tau muab cov neeg hais lus tsav tsheb rau qhov zoo tshaj plaws suab zoo?
Teb: Mount nyob rau sab sauv - ntu nruab nrab ntawm lub chaw them nyiaj, tig rau tus neeg teb xov tooj. Tsis txhob ua haujlwm hauv qab (kev pheej hmoo dej nyab) thiab cov haujlwm saum toj kawg nkaus (lub caij ntuj sov tshav kub ua kom cov laus). Yog tias ua tau, tawm 5mm + tshem tawm pem hauv ntej ntawm tus neeg hais lus-tsis txhob mount flush tiv thaiv phab ntsa sab hauv chassis.
Q4: Puas yog EV charging chaw nres tsheb lub suab tshaj tawm xav tau lub suab zoo?
Teb: Feem ntau xav tau kev pom meej, tab sis nruab nrab - zaus (500Hz-4kHz) kev hais lus yog qhov tseem ceeb. Sab nraum zoov lub suab nrov yog siab-yog tias lub suab tsis meej txaus, "Charging hauv kev kawm" suab zoo li "Chuhing hauv pwogwess," ua rau cov neeg siv kev paub dhau los.
Q5: Yuav saib dab tsi thaum hloov cov neeg xa khoom?
Teb: Peb lub ntsiab lus tseem ceeb: ① Dimensions yuav tsum phim raws nraim (qhov chaw nruab yog tsau); ② rhiab heev sib txawv yuav tsum nyob twj ywm nyob rau hauv ± 3dB (lub ntim hloov ib yam nkaus thiab pom tseeb); ③ Txheeb xyuas txhua qhov tsis sib xws ntawm daim ntawv spec (lub zog, impedance, ntau zaus)-tsis yog "ze txaus."
