Xyoo tas los, peb tau txais kev hu xov tooj los ntawm cov neeg siv khoom uas tau hloov cov neeg hais lus tsav tsheb. Lawv cov neeg hais lus Bluetooth lub suab bass thaj tsam tau tag nrho " ploj lawm" - cov neeg siv tau yws txog "muffled suab tsis muaj kev nkag mus," thiab tus nqi rov qab dhia mus rau 15%.
Qhov no tsis yog ib qho xwm txheej cais. XDEC tau ua haujlwm ntau pua ntawm Bluetooth hais lus hom, thiab peb tau pom tias cov teeb meem hloov pauv ntawm tus neeg siv khoom muaj ntau heev. Niaj hnub no, kuv xav pab cov tswv lag luam uas tab tom txiav txim siab hloov cov neeg hais lus tsav tsheb pom cov teeb meem uas cov chaw tsim khoom yuav tsis qhia koj txog.
1. Case Review: Cov neeg siv khoom uas Bass "Vanished" tom qab muab kev hloov pauv
Mr. Chen los ntawm Zhejiang xeev ua Bluetooth hais lus rau export. Xyoo 2024, nws tau hloov cov neeg hais lus tsav tsheb vim tus nqi. Thaum xub thawj, cov qauv kuaj tau zoo, tab sis tom qab ntau lawm, lawv pom:
Bass teb tau pom tias tsis muaj zog - lub nruas ntaus uas siv los ua punchy tam sim no suab "floating"
Pom tseeb distortion ntawm qhov ntim siab, nrog cov neeg siv khoom tshaj tawm "lub suab tawg"
Tsis zoo sib xws ntawm pawg - Batch A thiab Batch B suab zoo li ob yam khoom sib txawv
Thaum Mr. Chen tom qab tuaj rau peb los tshuaj xyuas, peb pom cov teeb meem tshwm sim los ntawm peb thaj chaw:
1. Tsuas yog saib lub zog ntsuas, tsis quav ntsej F0 (Resonance zaus)
Tib lub zog tsis txhais hais tias tib lub suab bass thaj tsam. Txawm tias zoo tib yam 52mm, 4Ω, 10W hais lus, F0 hloov ntawm 180Hz mus rau 280Hz tuaj yeem ua rau cov ntses bass thaj tsam txuas ntxiv tsis zoo. Qee qhov qis- cov chaw tsim khoom raug nqi nce F0 kom txuag tau cov nqi, ua rau "puffy" ntses bass thaj tsam zoo li daim ntawv tab sis suab nyias hauv qhov tseeb.
2. Tsis thov cov lus teb zaus nkhaus, tsuas yog saib cov nplooj ntawv spec
Spec sheet parameters yog "cov ntaub ntawv ntawv," thaum cov lus teb zaus qhia tau hais tias "kev ua tau zoo tiag tiag." Cov tuam txhab hais lus zoo tshaj plaws muab cov lus teb ntau zaus, qhia koj cov lus teb tseeb los ntawm qis mus rau qhov siab. Cov neeg muab nyiaj txiag feem ntau tsis tuaj yeem muab qhov no, lossis lawv cov nkhaus muaj qhov hloov pauv loj.
3. Me me batch xeem dhau, ntau lawm muaj teeb meem
Qauv sib xws ≠ loj ntau lawm sib xws. Ntau lub Hoobkas ua tau zoo ntawm cov qauv tab sis raug kev poob qis thaum lub sij hawm tsim khoom loj vim muaj teeb meem tswj cov txheej txheem. Qhov no yog vim li cas Mr. Chen xav tias Batch A thiab Batch B suab zoo li cov khoom sib txawv.
2. 5 Cov qauv rau Kev Txiav Txim yog tias Tus Neeg Hais Lus Tus Neeg Siv Khoom Siv Tau Zoo
Raws li peb cov kev paub dhau los 17 xyoo, ntawm no yog cov qauv tsim nyog rau kev ntsuas Bluetooth hais lus tus neeg siv khoom kev ntseeg tau:
Standard 1: Lawv puas tuaj yeem muab Thiele ua tiav -Qhov ntsuas me me
Cov chaw ua haujlwm tshaj lij muab cov kev txwv tsis pub dhau los suav nrog Fs, F0, Qms, Qes, Qts, Vas, thiab lwm yam. Yog tias lawv tsuas tuaj yeem muab koj "lub zog, impedance, rhiab heev" - ib qho trio yooj yim - nws qhia txog kev muaj peev xwm ua haujlwm tsawg.
Standard 2: Yog qhov zaus teb nkhaus du
Cov neeg hais lus tau zoo muaj cov lus teb zoo sib xws, nrog kev hloov pauv hauv ± 3dB. Yog hais tias qhov nkhaus fluctuates heev, tus neeg hais lus tsav lub suab ua haujlwm yuav tsis zoo.
Standard 3: Cov qauv kuaj puas muaj xws li ntev - lub sij hawm laus
Cov chaw tsim khoom lag luam ntseeg tau ua qhov kub / qis kub laus thiab cov av noo ntsuas ntawm cov qauv kom ntseeg tau tias kev ua haujlwm ruaj khov tom qab ntau lawm. Factories uas hla qhov no hloov tag nrho cov kev pheej hmoo rau cov neeg siv khoom.
Standard 4: Yog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis tsim nyog
Lub lag luam Bluetooth hais lus hloov tshiab sai sai, thiab ntau lub npe tsuas yog tsim 500-1000 units rau thawj zaug. Yog tias tus neeg muag khoom xav tau 5000 units MOQ, koj cov khoom lag luam iteration yuav ua rau siab heev.
Standard 5: Ua cov lus cog tseg rau kev xa khoom muaj ntawv pov thawj
Cov lus cog tseg tsis ntseeg. Cov chaw ua haujlwm tshaj lij qhia meej meej lub sijhawm xa khoom hauv cov ntawv cog lus thiab qhia txog kev lav phib xaub rau kev ncua. Qhov no yog tus cwj pwm kev pabcuam.
3. Cov txheej txheem pom zoo rau kev hloov cov khoom siv
Yog tias koj tab tom txiav txim siab hloov tus neeg hais lus tsav tsheb, ua raws li cov txheej txheem no:
Kauj Ruam 1: Thov 3 cov qauv los ntawm cov khoom sib txawv
Tsis txhob sim ib batch xwb. Kev sib xyaw ua ke ntawm cov khoom sib txawv yog qhov kev sim tiag tiag ntawm cov khoom muaj peev xwm.
Kauj ruam 2: Thov kom pom cov kab ntau lawm
Yog tias ntawm - tsis tuaj yeem tshawb xyuas qhov chaw, yam tsawg kawg thov kev txheeb xyuas video. Saib lawv cov qib automation, cov cuab yeej kuaj, thiab cov qauv kev ua haujlwm ntawm cov neeg ua haujlwm. Txawm hais tias lawv muaj chav kuaj suab tshwj xeeb yog qhov qhia tau tseem ceeb ntawm kev tshaj lij.
Kauj Ruam 3: Me me batch mus sib hais kom paub tseeb qhov ntau lawm sib xws
Rau thawj - lub sijhawm kev koom tes, pib nrog 1000-2000 units, soj ntsuam kev xa khoom tiag tiag thiab kev ua haujlwm zoo. Scale nce tsuas yog tom qab paub meej tias txhua yam ua tau.
Kauj Ruam 4: Txheeb xyuas cov kev qhia tshwj xeeb hauv kev sau ntawv
Sau tag nrho cov kev xav tau rau hauv daim ntawv cog lus - dimensional tolerances, F0 ranges, rhiab heev tolerances, cov kev cai sib xws. Qhov no muab cov ntaub ntawv rau koj yog tias muaj teeb meem tshwm sim.
💡 Ceeb toom tshwj xeeb:52mm loj rau Bluetooth hais lus tsav tsheb yog cov kev lag luam tseem ceeb specification, nrog ntau tus neeg muag khoom muaj. Tab sis qhov tseeb vim tias muaj ntau txoj kev xaiv, koj yuav tsum ceev faj. Ua ntej cov neeg muab khoom lag luam uas muab cov ntaub ntawv ua tiav, cov lus teb zaus nkhaus, thiab txaus siab ua cov xaj me me. Tus nqi qis tsis yog tus qauv nkaus xwb - kev ruaj ntseg thiab kev koom tes tus cwj pwm tseem ceeb sib npaug.
4. FAQ
Q1: Puas yog lub zog siab dua rau Bluetooth hais lus tsav tsheb?
Teb: Tsis tas. Lub hwj chim yuav tsum phim koj tus neeg hais lus enclosure tsim thiab amplifier Circuit Court. Yog tias lub kaw lus tsuas yog 0.3L, xaiv tus tsav tsheb 50W yuav ua rau muaj kev cuam tshuam los ntawm qhov tsis txaus amplification. Feem ntau, 5-15W tsav tsheb yog ib txwm muaj rau cov neeg hais lus Bluetooth - kev xaiv tshwj xeeb nyob ntawm cov khoom muag thiab qhov loj me.
Q2: Dab tsi yog qhov tseem ceeb dua - tsav tsheb rhiab heev lossis lub zog?
Teb: Rau Bluetooth hais lus, rhiab heev yog feem ntau tseem ceeb. High - cov tsav tsheb rhiab heev (90dB+) tuaj yeem ncav cuag cov ntim siab nrog lub tshuab hluav taws xob me me, muab lub zog zoo dua. Yog tias rhiab heev tsawg, txawm tias lub zog siab yuav ua rau tsis muaj zog - suab tawm.
Q3: Puas tuaj yeem 52mm tus neeg hais lus tsav tsheb los ntawm cov neeg muag khoom sib txawv ncaj qha hloov ib leeg?
Teb: Koj tsis tuaj yeem txiav txim los ntawm qhov loj ib leeg. Txawm hais tias muaj qhov sib npaug ntawm 52mm qhov ntev, kev tsim hluav taws xob sib nqus, lub suab coil specifications, thiab cov kab noj hniav hauv qab txhua qhov sib txawv. Ua ntej hloov, paub meej tias: seb qhov sib tw impedance, seb F0 zoo ib yam, seb qhov sib dhos qhov sib dhos. Qhov zoo tshaj plaws los thov cov lus sib piv parameter los ntawm tus neeg muag khoom tshiab.
Q4: Yuav ua li cas ntsuas kev sib tw tsav tsheb?
Teb: Nug tus neeg muag khoom rau cov ntaub ntawv soj ntsuam batch tsis ntev los no, tshuaj xyuas rhiab heev / F0 batch sib txawv. Cov neeg tsav tsheb zoo feem ntau tswj kev sib txawv hauv ± 1dB (rhiab heev) thiab ± 10Hz (F0). Kev sib txawv ntau dhau qhia tias tsis muaj kev tswj hwm tus txheej txheem.
Q5: Cov cim qhia dab tsi los tsom rau hauv kev sim me me?
Teb: Tshaj li qhov tsis sib xws, xyuam xim rau: qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv, kev sib piv lub suab tiag tiag, kev ua haujlwm hloov pauv tom qab ntsuas kub, thiab tus neeg muag khoom tom qab -muag teb ceev. Cov khoom me me yog txoj hauv kev zoo tshaj plaws los txheeb xyuas cov khoom lag luam muaj peev xwm.
