Lub pob zeb diamond vibrating membrane thiab nws txoj kev tsim khoom, ntshav, nplaim taws uas tsis muaj zog sib txawv ntawm cov pwm sib txawv, Thaum cov ntaub ntawv pob zeb diamond yog coated nyob rau saum npoo ntawm cov khoom siv pob zeb diamond sib txawv, yog li ntawd lub pob zeb diamond co zaj duab xis muaj tus widio bandwidth.
Thaum xaiv cov khoom siv ntawm cov diaphragm, cov kev txiav txim siab tseem ceeb yog cov yam ntxwv tawv thiab damping. Lub hardness txiav txim siab lub ntuj zaus ntawm cov khoom, thiab zaus ntawm cov khoom siv nyuaj ntawm cov khoom uas tsis muaj zog kuj qis. Cov ntaub ntawv nrog cov yam ntxwv ua kom zoo tuaj yeem ua rau lub siab vibbrane muaj cov lus tawm suab paj nruag lub siab ntawm cov paj hlwb smoother.
Kev lig kev cai Vibrating Memrating membrane cov ntaub ntawv suav nrog cov ntaub ntawv yas, thiab cov khoom siv hluav taws xob tsis txaus, thiab tsis txaus ua kom lawv muaj kev ua haujlwm siab tshaj plaws. Txawm hais tias tus hlau vibrating zaj duab xis muaj hardness zoo dua, muaj siab tawv me ntawm xws li, ti, thiab lwm yam kim. Cov ntaub ntawv tej hub tseem muaj cov teeb meem ntawm cov txheej txheem sib txawv. Vim yog cov khoom siv zoo tshaj plaws thiab lub zog ntawm cov khoom siv pob zeb diamond, nws yog qhov haum rau kev tsim lub teeb pom kev zoo, thiab tuaj yeem siv rau hauv nruab nrab- thiab ntau zaus hais lus. Lub suab xav tau yog tsim los ntawm kev co cov kev co ntawm lub diaphragm. Qhov siab dua qhov ntau zaus ntawm cov diaphragm, cov stricter cov tshuab zog muaj zog thiab cov khoom siv pob zeb diamond los ua kom cov diaphragm tuaj yeem ua tiav lub hom phiaj no.
Feem ntau hais lus, lub vibrating memrrane muaj qhov txwv ntawm cov lus teb zaus. Txawm li cas los xij, txawm hais tias lub vibrating memrating yog ua los ntawm pob zeb diamond lossis lwm cov ntaub ntawv, lub ntuj muaj cov khoom siv tau tag nrho, uas txo nws bandwidth kev ua tau zoo. Cov yam ntxwv damping thiab rigidity tsis tuaj yeem hloov pauv kev sib cav, uas txwv nws lub suab zoo thiab cov sij hawm ua tau zoo thiab timbre. Yog li ntawd, yog tias koj xav tau cov khoom siv ntau zaus tau txais rau tib neeg lub pob ntseg, koj feem ntau yuav tsum tau teeb tsa ntau yam kev txwv thiab cov kev txwv sab saud kom ua tiav lub suab zoo tshaj plaws. Yog li ntawd, hauv kev kos duab ua ntej, muaj kev siv thev naus laus zis ntawm kev siv cov ntaub ntawv sib txawv los ua kom cov membrane vibrating. Qhov nruab nrab ib feem ntawm lub vibrating memrating yog ua los ntawm cov khoom siv nrog siab tawv, thiab lub nplhaib sab nraud yog ua los ntawm cov khoom siv tsis muaj zog. Tom qab ntawd ob ntu no tau koom nrog ib qho kev sib tw vibrating muaj ob qho sib txawv ntawm lub zog thiab cov tuab tuab tib lub sijhawm, thiab tuaj yeem npog cov bandwidth loj. Txawm li cas los xij, cov tuab tuab ntawm lub vibrating zaj duab xis feem ntau yog tsis tshua muaj nyias, thiab kev koom nrog ua haujlwm yog qhov nyuaj. Yog tias nws yog siv rau pob zeb diamond cov ntaub ntawv, nws tus neeg sawv cev ua ke thiab tus neeg sawv cev ua tau zoo heev, yog li nws tsis yooj yim thov rau cov khoom tawg.
Txhawm rau daws cov teeb meem saum toj no, tam sim no muaj cov qauv kev sib txawv, yog li nws tsis muaj kev co cov yam ntxwv sib cav thiab damping thiab damping kev co cov yam ntxwv sib tw thiab npog ntau ntau zaus. Cov.
Raws li lub pob zeb diamond vibrating membrane thiab nws cov qauv tsim khoom lag luam tau muab cov pwm tam sim no los ntawm cov pwm uas muaj zog ntxiv, thiab cov pwm tsis muaj zog kom ua kom sov cov pwm yog nthuav tawm qhov chaw sov uas tsis sib xws.
Piv txwv nrog
1. Lub thermal kuj hlau yog qhov chaw nruab nrab yog qhov chaw siab tshaj plaws (thiab kev xav tau ntawm cov tshuaj tiv thaiv sab nraud uas nthuav qhia lub nplhaib tsis sib luag.
2. Vim muaj kev cuam tshuam ntawm nthwv dej, amplitude, thiab sawv vuag zoo siab heev, kev pom zoo ntawm cov duab sib luag uas tsis yog kev faib tawm tsis sib xws.
3. Lub zog nplaim ris tsho rau sab nraud ntawm thaj chaw nruab nrab, thiab kev pom zoo ntawm cov tshuaj tiv thaiv kab ke nthuav qhia qhov tsis sib xws.
Qhov kub thiab cov kev txhawj xeeb thiab kev txhawj xeeb ntawm kev tsim kho los ntawm lub zog saum toj no lwj nrawm rau sab nraud; Yog li ntawd, sib txawv graph txoj haujlwm sib cuag nrog cov cheeb tsam sib txawv ntawm cov kev ua yeeb yam sib txawv nrog cov ntsiab lus sib txawv, ua rau cov pob zeb sib txawv, ua rau cov pob zeb diamond uas tsis muaj kev sib txawv. (Tsis muaj homogeneous) kev co tsiaj txhu, xws li hardness tam sim no tsis muaj kev faib tawm ntawm cov pwm ua daim duab pob zeb diamond. Cov ntsiab lus ntawm lub xeev pob zeb diamond suav nrog micro-lead ua (micro-lead ua), nano-lead ua (nano-lead) thiab lwm yam.
Raws li lub pob zeb diamond vibrating zaj duab xis tsim los ntawm cov kev tsim muaj tam sim no, thiab lub hardness thiab cov tuab ntawm thaj chaw nruab nrab yog loj, thiab cov tuab ntawm thaj chaw thaj yog me me. Qhov kev co ntawm txhua qhov cuam tshuam los ntawm lub hardness thiab cov nyhuv ntawm cov tuab muaj txawv ntuj ib txwm muaj, yog li ntawd tias lub pob zeb diamond sib txawv tuaj yeem muaj cov bandwidth loj.
