Electronic Cigarette Emitter Technology: Electret yog lub ntsiab tseem ceeb tam sim no, Silicon Mai tuaj yeem dhau los ua Kev Lag Luam Yav Tom Ntej

Ib yam li cov tub ntxhais atomization, uas tau muab faib ua ceramic core thiab paj rwb tub ntxhais, kuj tseem muaj cov khoom siv hluav taws xob siv hluav taws xob, feem ntau yog ob hom: electret thiab silicon microphone. Ntawm lawv, electret microphones yog tam sim no muaj, thaum silicon microphone yog suav tias yog yav tom ntej qauv.
Cia peb saib qhov kev sib piv ntawm ob hom hluav taws xob luam yeeb capacitive microphones. Feem ntau hais lus, lub microphone suav nrog ob ntu: lub sensor thiab ASIC nti. Kab lus no feem ntau tham txog qhov sib txawv ntawm qhov sensor.
1. Lub hauv paus ntsiab lus ntawm microphone induction - parallel phaj capacitors
Ua ntej, lub hauv paus ntsiab lus yog hais tias cov lus teb ntawm lub electret microphone thiab silicon microphone yog tsim los ntawm ib tug parallel phaj capacitor muaj li ntawm ib tug diaphragm thiab ib tug rov qab phaj. Lub siab sib txawv ntawm cov cua ntws ua rau lub diaphragm deform, thiab tom qab ntawd lub capacitance hloov. Tom qab tau lees paub thiab ua tiav los ntawm ASIC nti, lub teeb liab hluav taws xob yog qhov tso tawm, thaum kawg ua tiav qhov pib thiab nres ntawm cov luam yeeb hluav taws xob.
Lub ntsiab lus tseem ceeb yog qhov kev hloov pauv hauv capacitance.
Hauv kev tshawb fawb hauv Circuit Court, lub peev xwm ntawm lub capacitor los khaws cov nqi ntawm qhov muab hluav taws xob yog hu ua capacitance, sau C. Ib lub phaj sib luag capacitor yog hom yooj yim ntawm cov capacitor uas muaj ob lub phaj nyias nyias uas sib npaug rau ib leeg thiab cais los ntawm qhov chaw lossis dielectric.

Raws li cov qauv tsim ntawm parallel phaj capacitors, nws yog:
Lub taub hau hluav taws xob hluav taws xob ib txwm muaj: daim ntawv qhia phaj cheeb tsam A tseem ruaj khov, thiab dielectric capacitance ε lub neej ntawd yog huab cua, thiab cov cua ntws ua rau lub diaphragm deform - qhov kev ncua deb d ntawm lub diaphragm thiab electrode phaj hloov - ua rau muaj kev hloov pauv hauv capacitance;
Cov ntawv luam yeeb hauv hluav taws xob nrog cov roj xau: thaj tsam A ntawm cov ntawv qhia phaj tseem ruaj khov, thiab thaj tsam ntawm cov phaj electrode thiab cov diaphragm tsis yog huab cua, tab sis roj. Yog li ntawd, lub dielectric permittivity ε Hloov - ua rau lub capacitance hloov - nws tus kheej pib.
2. Electret microphone vs silicon microphone: qhov sib txawv ntawm cov qauv thiab diaphragm
Nyob rau hauv cov nqe lus ntawm cov qauv, feem ntau ntawm cov electret microphones muaj ib tug electrode phaj nyob rau sab saum toj thiab ib tug diaphragm nyob rau hauv qab, nrog rau qhov nyob rau hauv lub substrate. Qhov kev tsim no ua rau nws yooj yim rau cov electret microphones nkag mus rau cov roj thiab dej, ua rau muaj kev hloov pauv hauv dielectric permittivity thiab capacitance, xws li pib tus kheej.
Yog tias peb txais cov qauv tsim nrog lub phaj electrode nyob rau hauv qab thiab lub diaphragm nyob rau sab saum toj kom tsis txhob muaj roj to, txawm hais tias nws tuaj yeem zam cov roj to, nws yuav nyuaj rau kev sib sau ua ke thiab nce nqi ntau lawm.

Microscopic qauv ntawm lub taub hau microphone
Thiab capacitive silicon microphone, raws li cov kws tshaj lij, tuaj yeem tsim los ua cov qauv nrog lub diaphragm nyob rau sab saum toj thiab lub phaj hauv qab. Meanwhile, tsis zoo li cov polymer diaphragm ntawm lub electret microphone, lub diaphragm ntawm silicon nplej yog ib tug silicon raws li daim nyias nyias.
Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, electret microphones feem ntau manually assembled, thiab qee cov tuam txhab uas muag siv automated los ua ke, thaum silicon microphones siv MEMS technology.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, lub electret microphone yog tam sim no siv dav siv hluav taws xob microphone, nrog rau qhov zoo ntawm cov khoom lag luam ruaj khov thiab tus nqi qis. Tib lub sijhawm, kuj tseem muaj qee qhov tsis txaus, xws li tsis muaj roj tsis kam, tsis muaj cua sov dissipation, thiab tsis muaj peev xwm dhau SMT.
Yog tias peb xav nrhiav kev ua haujlwm zoo dua thiab ua haujlwm ntau dua, qhov zoo ntawm silicon nplej yuav maj mam dhau los ua qhov tseem ceeb, xws li dej tsis zoo thiab roj resistant, me me, kub tsis kam, SMT tsis kam, sib xws thiab ruaj khov, thiab lwm yam.
Qhov teeb meem tseem ceeb ntawm silicon nplej yog nws cov nqi, uas txhais tau hais tias "txhua yam zoo, tab sis nws kim heev". Cov xov xwm zoo yog tias nrog kev nce qib ntawm thev naus laus zis, raws li cov tuam txhab tsim khoom lag luam, nyob rau hauv cov ntaub ntawv ntawm kev siv ntau lawm, nws cov nqi tuaj yeem sib piv nrog cov electret microphones.
Cov ntsiab lus
Cov saum toj no yog kev sib piv ntawm ob hom hluav taws xob luam yeeb capacitive microphones. Ntxiv rau capacitive microphones, kuj tseem muaj cov microphones tiv taus. Peb yuav muaj sijhawm los qhia lawv hauv lwm tshooj tom qab.
Zuag qhia tag nrho, muaj ob lub ntsiab lus ntawm lub microphones: electret thiab silicon microphone. Ob leeg muaj qhov sib txawv ntawm cov qauv, cov khoom siv diaphragm, kev tsim khoom, thiab kev ua haujlwm. Hauv kev siv cov luam yeeb hluav taws xob, electret microphones yog lub ntsiab lus tseem ceeb tam sim no, thaum silicon microphone suav tias yog yav tom ntej.
