Koj puas paub? Ntiaj teb no studio saib lub mloog pob ntseg lag luam loj hlob 23% hauv 2024. Podcast ntau lawm, suab cov ntsiab lus tsim, thiab esports streaming yog tsav xav tau. Tab sis ntawm no yog qhov teeb meem: ntau tus kws tshaj lij audio thiab cov thawj coj khoom lag luam tau ua yuam kev raug nqi thaum xaiv lub mloog pob ntseg hais lus tsav tsheb rau studio saib.
Tom qab 17 xyoo hauv kev tsim cov neeg hais lus, peb lub Hoobkas Shenzhen tau pom ntau qhov xwm txheej uas cov tuam txhab xaiv cov neeg hais lus tsis raug, ua rau cov nqi xa rov qab siab, cov neeg siv khoom tsis zoo, thiab cov khoom puas tsuaj.
Hauv phau ntawv qhia no, peb yuav qhia txog qhov tseem ceeb uas koj YUAV TSUM ntsuas ua ntej tso koj qhov kev txiav txim.
1. Nkag siab saib lub mloog pob ntseg hais lus tsav tsheb vs
Ntau tus neeg yuav khoom xav tias saib lub mloog pob ntseg zoo ib yam li cov neeg hais lus pob ntseg. Nov yog qhov yuam kev tseem ceeb:
Flatter zaus teb: Saib cov neeg hais lus xav tau cov lus teb tiaj tus hauv ± 3dB sib txawv. Cov neeg hais lus feem ntau muaj "xim" cov lus teb kom zoo dua "xav" tab sis qhov no tsis tsim nyog rau kev saib xyuas kev tshaj lij
Tsawg THD Cov Cai: Tag nrho Harmonic Distortion yuav tsum tsawg dua lossis sib npaug li 0.5% txhawm rau tiv thaiv kev mloog qaug zog thaum lub sijhawm ntev studio
Higher Consistency Standards: Cov tsav tsheb sab laug thiab sab xis yuav tsum sib phim hauv 1dB rhiab heev thiab 5% F0 sib txawv. Cov khub tsis sib haum ua rau cov duab tso suab
Txheem impedance: Cov kws tshaj lij saib xyuas siv 32Ω rau kev sib raug zoo nrog lub suab sib txuas, cov khoom sib xyaw, thiab cov khoom siv txawb
Hauv luv luv: Saib xyuas lub mloog pob ntseg yog cov cuab yeej siv tau zoo, tsis yog cov khoom siv hluav taws xob. Kev xaiv yuam kev=30% tus nqi rov qab.
2. Rau qhov tsis tseem ceeb uas koj yuav tsum tau kuaj xyuas
| Parameter | Yam tsawg kawg nkaus | Txuj kev tshaj lij | Yuav ua li cas kom tsis txhob Pitfalls |
|---|---|---|---|
| Loj | Φ30-40mm | Φ36-40mm | 40 hli dominates (44% kev ua lag luam); me=tsis muaj zog bass |
| Impedance | 32Ω±15% | 32Ω±5% | Tshawb xyuas qhov khoom siv sib xws |
| rhiab heev | Ntau dua lossis sib npaug rau 100dB SPL | Ntau dua lossis sib npaug rau 105dB SPL | High rhiab heev ≠ zoo |
| Zaus teb | 20Hz-20kHz | 10Hz-40kHz (Hi-Res) | Tshawb xyuas cov lus teb zoo, tsis yog cov lus teb |
| THD Distortion | Tsawg dua lossis sib npaug li 1% | Tsawg dua lossis sib npaug li 0.3% | Thov kev ntsuas qhov nkhaus |
| F0 Resonance | Tsawg dua los yog sib npaug rau 300Hz | Tsawg dua lossis sib npaug li 200Hz | Txo F0=bass thaj tsam txuas ntxiv |
💡 Cov Lus Qhia Xaiv: Φ40mm yog tus qauv kub rau saib lub mloog pob ntseg (44% kev ua lag luam sib koom). Qhov loj me no muab qhov sib npaug zoo tshaj plaws ntawm cov ntses bass thaj tsam txuas ntxiv thiab cov ntaub thaiv npog tuab. Rau kev nkag- qib saib, xav txog Φ36mm (10-15% tus nqi txo).
3. Enclosure Design Impact on Speaker Performance
Lub acoustic enclosure tsim ncaj qha txiav txim seb koj tus neeg hais lus tsav tsheb ua tau zoo:
Tsheb Cavity Volume: Φ40mm tsav tsheb xav tau ntau dua los yog sib npaug rau 3cc rear kab noj hniav. me me dhau=txhawb nqa, hnyav ntses bass thaj tsam
Pem Hauv Ntej Cavity Qhov tob: Vented qhov rau diaphragm nrug: 0.5-1mm. tob dhau=treble yob-tawm; ntiav heev=break-up distortion
Qhov Vent Hole Design: Tswj pem hauv ntej -rov qab siab sib npaug. Pom zoo 5-8% qhib cheeb tsam piv
Acoustic Sealing: Sab laug- txoj cai cais tawm ntau dua lossis sib npaug li 25dB. Tsis zoo sealing ruins stereo duab
4. Kev sib xyaw ua ke & kev tswj hwm ntau lawm
Saib xyuas lub mloog pob ntseg feem ntau yog tsim nyob rau hauv batch ntawm 500-10, 000+ units. Tsis zoo sib xws ua rau:
L-R channel mismatch (Ntau dua lossis sib npaug rau 2dB sib txawv)
Ntau zaus teb variation (cov neeg siv khoom pom sab laug- txoj cai txawv)
Kev lees paub siab (tshwj xeeb tshaj yog los ntawm cov khoom siv nrog dav F0 faib)
Thov cov no los ntawm koj tus neeg muag khoom hais lus:
100% F0 soj ntsuam cov ntaub ntawv
rhiab heev- ntim ntim (hauv -batch sib txawv Tsawg dua lossis sib npaug rau 1dB)
THD nkhaus sib piv kab kos
5. Cov lus nug FAQ
Q1: Vim li cas thiaj saib xyuas lub mloog pob ntseg feem ntau siv 32Ω impedance?
A: 32Ω yog tus qauv kev lag luam rau kev sib tw siab tshaj plaws. Tsawg dhau=siab tam sim no thov=teeb meem hauv pem teb. Siab dhau=yuav tsum muaj lub zog ua kom muaj zog ntau dua . 32Ω ua haujlwm nrog cov khoos phis tawj, suab interfaces, mixers, thiab cov khoom siv mobile.
Q2: Dab tsi yog Hi-Res daim ntawv pov thawj xav tau rau cov neeg hais lus?
A: Nyob zoo-Res Audio xav tau ntau dua lossis sib npaug rau 40kHz zaus teb. Qhov no txhais tau hais tias siv cov khoom siv lub teeb diaphragm (PEN, PEEK) thiab cov hlau nplaum sib nqus flux siab. Tus nqi yog 20-30% siab dua, tab sis muab kev daws teeb meem zoo tshaj plaws.
Q3: Yuav ua li cas ntsuas tus neeg hais lus tus neeg muag khoom kev tswj xyuas zoo?
A: Tshawb xyuas peb qhov ntsuas: ① Lawv puas muab 100% F0 kev tshuaj xyuas tag nrho? ② Lawv puas siv AOI online (Kev Tshuaj Xyuas Kev Kho Mob Tsis Zoo)? ③ Puas yog lawv batch defect npaum li cas tsawg dua lossis sib npaug li 1%? Yog tias lawv hais tias "kev tshuaj ntsuam xyuas yog txaus," lawv QC tsis muaj zog.
Q4: Dab tsi yog lub neej ntev ntawm lub mloog pob ntseg tham?
A: Kev siv lub neej ib txwm yog 5,000-10,000 teev, nyob ntawm qhov kev laus ntawm lub diaphragm thiab lub suab coil hnav. Xaiv cov neeg hais lus nrog cov ntaub / ua npuas dej ib puag ncig + sib xyaw diaphragm rau 30% lub neej ntev dua li cov ntshiab mylar diaphragms.
Q5: Ntau npaum li cas qhov chaw qhib qhov chaw cuam tshuam rau lub suab zoo?
A: Qhov tseem ceeb. Qhov chaw qhib txiav txim siab qhov thaiv Q- yam ntxwv thiab cov ntses bass thaj tsam. Ntsuam xyuas thaj chaw sib txawv nrog kev ntsuas dawb - teb thaum lub sij hawm prototyping. Nrhiav qhov zoo tshaj plaws qhib cheeb tsam ua ntej pawg ntau lawm.
