Dab tsi "muffled ABC" qhia peb txog kev xaiv tsav tsheb Mylar
Peb lub hlis dhau los, cov ntsiav tshuaj kawm OEM nyob rau sab hnub tuaj Europe hu ua peb cov kab engineering. Lawv cov neeg muab khoom yav dhau los tau xa tawm ib pawg ntawm Φ31mm Mylar tsav tsheb, thiab cov neeg siv kawg tau yws yws: tsab ntawv "S" hauv "nab" suab zoo li "shhh", thiab peb- xyoo- cov laus tsis tuaj yeem qhia tau tias lub cuab yeej hais "B" lossis "D".
Lub OEM tau npaj los rhuav tshem tag nrho lub platform thiab tsiv mus rau Φ40mm tsav tsheb - tus nqi rov qab - cov cuab yeej uas yuav tau thawb lawv lub community launch txog plaub lub hlis. Peb nug ib lo lus nug ua ntej kos npe rau ib yam dab tsi:koj puas tuaj yeem xa peb lub chamber ntim tom qab tus tsav tsheb?
Nws tig tawm tus neeg tsav tsheb dhau los tau ua ke nrog 3.2cc rov qab chamber - ntiav heev rau F0 ntawm qhov tshwj xeeb Mylar unit. Peb tau xa ib tug tuned Φ31mm Mylar hais lus tsav tsheb los ntawm XDEC's M- hom tsev neeg, nrog rau 5.0cc rov qab- cov lus qhia ntim, thiab BOM dhau lub suab QA hauv 11 hnub.
Ib rooj plaub no yog vim li cas tsab xov xwm no tshwm sim. Mylar tsav tsheb yog pheej yig, compact, thiab - thaum xaiv kom raug - ci ntsa iab rau cov me nyuam cov khoom siv kawm ntawv. Tab sis peb qhov pitfalls ntsiag to rhuav tshem cov kev kawm ntsiav tshuaj ntau dua li lwm qhov teeb meem engineering uas peb tau pom hauv 17 xyoo ntawm kev tsim cov tsav tsheb.
Peb yam kab lus no yuav cawm koj ntawm:(1) xaiv tus tsav tsheb uas dhau- lub zog rau lub chamber nruj, (2) tso siab rau 76dB spec ntawm Mylar datasheet (yuav luag ib txwm ib qho tsis raug lossis Y- tus lej ntaus swb rau hauv M- hom kab), thiab (3) dhau -spec'ing 2W tsav tsheb rau ib qho khoom siv 4 tus tib neeg tsuas yog xav tau 4 Hz suab.
Peb qhov pitfalls uas ntsiag to tua kev kawm cov ntsiav tshuaj suab (thiab yuav ua li cas xwb)
Pitfall 1 - Kho "rhiab heev" raws li tus lej xwb uas tseem ceeb
Lub ntxiab:Tus neeg saib xyuas kev yuav khoom pom 90dB ntawm Mylar datasheet thiab 88dB ntawm lwm tus, thiab xaj kom nrov dua.
Dab tsi mus tsis ncaj ncees lawm:Ob tus neeg tsav tsheb zaum ntawm 90dB / 88dBnpe, tab sis thawj yog90 ± 3dB(ntau 87-93dB) thiab qhov thib ob yog88 ± 1dBnrog XDEC qhov sib tw -pair grading. Hauv ib ntsiav tshuaj nrog ib tus neeg hais lus, qhov sib txawv tsis pom. Hauv ib lub ntsiav tshuaj nrog ob tus neeg hais lus (lub suab lus Askiv zaj lus qhia), ± 3dB khub tsim sab laug- txoj cai tsis ncaj ncees uas cov menyuam pob ntseg tuaj yeem nqa tam sim.
Yuav ua li cas hloov:Qhia qhov kam rau ua, tsis yog lub ntsiab lus. Rau ib qho dual - tsav tsheb kev kawm ntaus ntawv, nug ±1dB matched-pair grading thiab ntxiv rau BOM kab - tsis yog cov ntaub ntawv xwb.
Pitfall 2 - Cia lub chamber ntim drift tom qab thawj ID kho dua
Lub ntxiab:Kev tsim qauv yog khov ntawm 4.0cc rov ntim; pab pawg acoustics xeem nrog Φ28mm Mylar qauv; loj ntau lawm hloov mus rau Φ31mm Mylar "sib npaug" uas tsis muaj leej twg re-validated.
Dab tsi mus tsis ncaj ncees lawm:Txhua 1 hli ntawm diaphragm txoj kab uas hla thawb lub F0 los ntawm ~ 15-20Hz ntawm lub khob hliav qab Mylar. Lub 31mm chav tsev, ua ke nrog 4.0cc chamber, muaj F0 nyob ib ncig ntawm 380Hz - tsawg dhau los ua kom huv si rov tsim dua 2-4kHz "muaj band" nyob qhov twg cov lus pom tseeb nyob. Cov menyuam kawm ntawv phonics ua av nkos.
Yuav ua li cas hloov:Kho tus neeg hais lus tsav tsheb thiab lub chamber rov qab ua ib qho acoustic system. Ntawm XDEC, peb pab pawg FAE muab rov qab - ntim vs F0 nkhaus nrog txhua tus qauv Mylar, yog li pab pawg acoustics tuaj yeem xaiv lub chamber loj ua ntej siv lub tsev.
Pitfall 3 - Spec'ing tus tsav tsheb 2W thaum lub cuab yeej tsuas xav tau 0.5W
Lub ntxiab:"Tus lej loj=zoo dua" - yog li 2W Mylar raug xaiv "tsuas yog hauv rooj plaub".
Dab tsi mus tsis ncaj ncees lawm:Overpowered Mylar cones nyob rau hauv me me chamber tsim harmonic distortion nyob rau hauv lub 1-2kHz ntau, uas yog raws nraim qhov twg cov tsiaj ntawv, phonics, thiab lub suab nyob. Cov neeg siv kawg yws txog "harshness" los yog "buzzing" ntawm nruab nrab ntim. Tsis tas li ntawd, tus tsav tsheb 2W rub tawm tam sim no tsis zoo - tsis zoo rau cov ntsiav tshuaj uas xav tau 8-teev roj teeb lub neej.
Yuav ua li cas hloov:Muab lub zog ntsuas rau qhov tseeb siv cov ntaub ntawv acoustic. Rau 4-nti kev kawm ntsiav tshuaj nrog 5-8mm hais lus kab noj hniav, 0.5W rau 1.0W feem ntau yog lub hnab ntawv zoo. Cov lej loj dua yog kev lag luam kev lag luam, tsis yog tus tsim yeej.
