Kev tsim kho hauv cov tshuab luam yeeb hauv hluav taws xob thiab kev hloov pauv kev lag luam

Ib qho kev siv dag me me yog microphone yog ib qho ntawm cov neeg luam yeeb hauv hluav taws xob, tsis tau muaj cov khoom siv ua haujlwm hauv hluav taws xob Tom qab ntau tshaj li ib xyoo caum ntawm kev siv tshuab thev naus laus zis, los ntawm cov ntsiab lus hluav taws xob hluav taws xob, nws tsis yog cov kev lag luam cov khoom lag luam rau cov qauv thiab kev txawj ntse.
Kab lus no yuav coj koj mus rau uncover txoj kev txhim kho hauv tshuab hluav taws xob, txheeb xyuas cov txiaj ntsig hluav taws xob ua kom zoo nkauj ntawm silical microphone tshuab, thiab tos ntsoov rau yav tom ntej ntawm kev lag luam.
I. Kev tsim kho cov keeb kwm ntawm cov tshuab luam yeeb hauv hluav taws xob diaphragm
① ①6 hluav taws xob diaphragm microphone


Nyob ib ncig ntawm 2010, hluav taws xob microphone pib nkag mus rau hauv cov luam yeeb hauv hluav taws xob. Hom microphone muaj cov hmoov av-pov thawj, ib lub tsev, ib lub plab electrode phaj, lub gasket, ib kab noj, ib kab noj hniav, thiab PCB board. Nrog cov txheej txheem tsim tsim kom paub tab thiab cov nqi qis, hluav taws xob hluav taws xob ua lag luam sai sai ntawm kev ua lag luam thiab los ua tus qauv kev teeb tsa rau cov khoom lag luam luam yeeb thaum ntxov. Txawm li cas los xij, vim muaj teeb meem xws li cov kev ua kub tsis zoo, qhov tsis sib xws, thiab tsis ruaj khov, cov kev txwv ntawm cov khoom siv hluav taws xob tau ua kom pom tseeb nyob rau xyoo tas los no.
② 2718 Silicon Microphone

Nyob rau hauv 2018, nrog kev vam meej ntawm Mems (micro-cov tshuab siv hluav taws xob) thev naus laus zis pib mus rau hauv kev pom cov tshuab luam yeeb hauv hluav taws xob. Piv nrog cov kev siv hluav taws xob ib txwm, lub 2718 silicon microphone hloov pauv thev naus laus zis thiab sib xyaw nrog cov chips fips kom ua tiav cov paib ntsuas digital. Nws cov yam ntxwv zoo xws li kub siab tiv, kev ua kom zoo, thiab cov roj muaj txiaj ntsig zoo sib xyaw rau cov luam yeeb hauv hluav taws xob.
③φ6 kaw silicon microphone

Nyob rau hauv ib nrab ntawm 2024, lub lag luam pov thawj cuam tshuam kev nthuav dav. φ6 ib-zaug molded moulded silicon microphones tau pib tsim mus rau kev ua lag luam. Tsis tsuas yog nws daws cov teeb meem ntawm cov kub ua tsis kam, cov roj tsis zoo, tab sis kuj hais txog cov kev pheej hmoo hluav taws xob thiab cov teeb meem ntawm φ6 sib khi cov pob zeb hauv silicon microshones. Tam sim no, ntau lub tuam txhab tau pib loj ntau lawm.
Ii. Cov txiaj ntsig zoo ntawm silicon microphones piv rau hluav taws xob diaphragm microphones
Cov ntsiab cai ntawm pob zeb pob zeb thiab hluav taws xob hluav taws xob thiab hluav taws xob phaj capactrict capactrict capactrict capactruction. Los ntawm kev siab sib txawv ntawm lub airflow, yog li hloov cov cim hluav taws xob muaj nuj nqis, uas yog tom qab ntawd ua tiav cov cim hluav taws xob thiab tso tawm los ntawm cov hluav taws xob uas yog qhov pib thiab nres ntawm cov luam yeeb hauv hluav taws xob.
(Qauv thiab cov ntsiab cai ntawm cov tshuab hluav taws xob hluav taws xob microphone)
(Qauv thiab cov ntsiab cai ntawm 2718 silicon microphone
(Cov qauv thiab cov ntsiab cai ntawm φ6 ib-zaug moulded silicon microphones)
Lub ntsiab txawv ntawm silicon microphones thiab electret Diaphragm micgrocones nyob rau hauv cov diaphragm cov ntaub ntawv thiab ntim cov qauv. Nyob rau hauv cov nqe lus ntawm diaphragm cov khoom, cov diaphragms ntawm silicon microphones feem ntau yog tsim ib zaug siv tshuaj tivthaiv, ua kom muaj qhov kub thiab txias, thiab kub ua tsis taus, thiab tsis tshua muaj kev cuam tshuam. Thawj lub peev xwm tseem muaj nuj nqis nyob ib ncig ntawm 1 PF, haum rau txhua yam kev ua haujlwm ntawm kev ua lag luam. Lub diaphragms ntawm elechragm microphones siv tsiaj / PPS yas yas, cov roj tsis zoo, thiab muaj feem xyuam rau deformation thiab kub - kub tsis kam. Thawj qhov nqi capital cape yog ib ncig ntawm 30 pf, haum rau qee yam ASICs.


Nyob rau hauv cov nqe lus ntawm ntim, lub cim micro-electromechanical (MEMS Nyob rau hauv cov nqe lus ntawm ntim precision, cua sov dissipation kev ua tau zoo, cov khoom lag luam tawm, lub cim tau ntau dua, thiab ntau dua cov kab mob microphone tau pom tseeb zoo.

III. Cov ntsiab lus txiav txim siab qhov zoo ntawm SI-microphones
Nrog rau kev txhim kho ntawm cov luam yeeb hauv hluav taws xob, sib nrug los ntawm kev lag luam kev lag luam zoo nkauj christic micro, thiab AAC, ntau lwm cov tuam ntxhab tsis ntev los no launched si-microphones. Txawm li cas los xij, rau cov tuam ntxhab kom ua tiav cov nplai loj cov khoom xa tuaj ntawm Si-microphones, lawv yuav tsum tau ntsib tsib tus ntxhais tseem ceeb:
① Lawv yuav tsum txhim kho lub microphones tshwj xeeb rau cov luam yeeb hauv hluav taws xob ③ Lawv xav tau kev paub meej thiab kev ntsuas cov khoom lag luam loj ntawm cov khoom lag luam ntawm si-microphone hauv khw

Txij li thaum lub tshuab muag hluav taws xob yog ib qho pob khoom, nws daim ntawv thov cov xwm txheej tshwj xeeb, thiab nws muaj kev ua tau zoo rau cov tshuaj-sensor, thiab cov txheej txheem ntim ntim. Yuav kom ua tiav cov nplai loj ntawm cov pob zeb Silicon, nws tseem yuav tsum tau lub sijhawm ntev ntawm cov txheej txheem pov thawj kev lag luam thiab kev lag luam tsim nyog. Txawm tias cov chaw tsim tshuaj paus muaj tau ntsib ntau yam xwm txheej zoo. Kev lag luam insiders feem ntau ntseeg tias cov neeg nkag tshiab mus rau silicon Microphone khw tseem muaj ntau qhov pitfalls kom zam dhau thiab txoj kev ntev ua ntej kev ua tiav ntau lawm.
4. Ntsiab lus
Cov kev sib tw hauv kev lag luam luam yeeb hauv hluav taws xob yog qhov tseem ceeb kev sib tw rau cov tseem ceeb thev naus laus zis. Lub tswv yim tshuab hluav taws xob ntawm cov tshuab luam yeeb Microphone tsis yog tsuas yog kho vajtse hloov kho tab sis kuj rov kho dua tshiab ntawm cov qauv kev lag luam thiab kev ua haujlwm zoo. Nrhiav rau pem hauv ntej, nrog kev siv thev naus laus zis thiab kev siv ua cov khoom lag luam silicon microphone yuav ua rau cov kev daws teeb meem zoo li qub thiab cov pa luam yeeb hauv hluav taws xob thiab cov pa luam yeeb hauv hluav taws xob kom txav mus rau ntawm qhov siab dua.
