Ib daim nyias nyias vibrating pob zeb diamond thiab nws txoj kev tsim khoom, dhau lub zog tsis sib xws (xws li thermal resistance wire, plasma, nplaim taws) uas ua rau cov roj sib cais saum cov pwm, siv qhov deb ntawm qhov nkhaus ntawm cov pwm thiab lub zog tsis sib xws uas ua rau cov roj sib cais ua rau muaj kev sib txawv ntawm cov cua sov. Thaum cov khoom siv pob zeb diamond tau coated rau ntawm qhov chaw ntawm cov pwm, kev loj hlob ntawm cov khoom siv pob zeb diamond yog txawv, yog li ntawd cov yeeb yaj kiab vibration pob zeb diamond muaj cov yam ntxwv tsis sib xws, yog li ntawd cov yeeb yaj kiab vibration pob zeb diamond muaj lub suab bandwidth dav dua.
Thaum xaiv cov khoom siv ntawm lub diaphragm, qhov tseem ceeb tshaj plaws yog qhov nyuaj thiab cov yam ntxwv ntawm kev ntub dej. Qhov nyuaj txiav txim siab qhov zaus ntuj ntawm cov khoom siv, thiab qhov zaus ntuj ntawm cov khoom siv uas muaj qhov nyuaj siab yog qhov siab, thiab vice versa, qhov zaus ntuj ntawm cov khoom siv uas muaj qhov nyuaj tsawg kuj qis. Cov khoom siv uas muaj cov yam ntxwv ntawm kev ntub dej zoo tuaj yeem ua rau lub ntsej muag vibrating muaj kev teb vibration du dua, ua rau qib suab siab ntawm lub ntsej muag vibrating du dua.
Cov ntaub ntawv siv los ua vibrating membrane feem ntau suav nrog ntawv, cov khoom siv yas polymer, cov hlau (Be, Ti, Al), ceramics, thiab lwm yam. Cov ntaub ntawv ntawv thiab polymer muaj cov yam ntxwv zoo damping, tab sis tsis muaj zog thiab yooj yim puas tsuaj, thiab qhov nyuaj qis tsis txaus los ua rau lawv. Qhov siab tshaj plaws ua haujlwm zaus yog txwv. Txawm hais tias cov hlau vibrating zaj duab xis muaj qhov nyuaj dua, cov hlau siab-hardness xws li Be, Ti, thiab lwm yam kim thiab nyuaj rau ua. Cov ntaub ntawv ceramic kuj muaj teeb meem ntawm cov txheej txheem sintering nyuaj. Vim yog cov khoom siv kho tshuab zoo heev thiab lub zog ntawm cov khoom siv pob zeb diamond, nws yog qhov tsim nyog rau kev tsim cov diaphragms sib dua, siab-rigidity, thiab tuaj yeem siv rau hauv nruab nrab- thiab siab-zaus hais lus. Lub suab xav tau yog tsim los ntawm qhov zaus vibration ntawm diaphragm. Qhov siab dua qhov zaus vibration ntawm diaphragm, qhov nruj dua qhov kev xav tau ntawm lub zog kho tshuab thiab qhov zoo ntawm diaphragm, thiab kev siv cov ntaub ntawv pob zeb diamond los ua diaphragm tuaj yeem ua tiav lub hom phiaj no.
Feem ntau hais lus, daim nyias nyias vibrating muaj qhov txwv siab tshaj plaws ntawm qhov zaus teb. Txawm li cas los xij, tsis hais seb daim nyias nyias vibrating puas yog ua los ntawm pob zeb diamond lossis lwm yam khoom siv, qhov zaus ntuj raug txwv rau ib qho tshwj xeeb vim yog cov khoom siv sib xws, uas txwv nws cov kev ua tau zoo bandwidth. Cov yam ntxwv damping thiab rigidity tsis tuaj yeem hloov pauv arbitrarily, uas txwv nws lub suab zoo thiab timbre kev ua tau zoo. Yog li ntawd, yog tias koj xav npog qhov zaus ntau yam uas tib neeg pob ntseg lees txais, koj feem ntau yuav tsum teeb tsa ntau lub diaphragms nrog cov bandwidths sib txawv thiab zaus siab tshaj plaws tib lub sijhawm kom ua tiav qhov zoo tshaj plaws suab zoo. Yog li ntawd, hauv kev kos duab ua ntej, muaj cov thev naus laus zis ntawm kev siv cov khoom sib txawv los ua daim nyias nyias vibrating hauv ntu. Lub hauv paus ntawm daim nyias nyias vibrating yog ua los ntawm cov khoom siv uas muaj qhov nyuaj siab, thiab lub nplhaib sab nraud yog ua los ntawm cov khoom siv uas muaj qhov nyuaj qis. Tom qab ntawd ob ntu no tau koom ua ke los ua ib qho. Daim nyias nyias vibrating muaj ob qho khoom siv sib txawv hardnesses thiab thicknesses tib lub sijhawm, thiab tuaj yeem npog bandwidth loj dua. Txawm li cas los xij, qhov tuab ntawm zaj duab xis vibrating feem ntau yog nyias heev, thiab kev koom ua ke yog qhov nyuaj. Yog tias nws yuav tsum tau siv rau cov ntaub ntawv pob zeb diamond, nws cov thev naus laus zis sib txuas thiab tus neeg sawv cev sib txuas yog cov teeb meem loj heev, yog li nws tsis yooj yim rau kev siv rau cov ntaub ntawv pob zeb diamond.
Yuav kom daws tau cov teeb meem saum toj no, qhov kev tsim kho tshiab no tau hais txog zaj duab xis vibrating pob zeb diamond thiab nws txoj kev tsim khoom, uas tuaj yeem hloov qhov nyuaj, tuab thiab cov yam ntxwv damping ntawm ntau thaj chaw ntawm zaj duab xis vibrating pob zeb diamond, yog li nws muaj cov yam ntxwv tsis sib xws thiab npog ntau zaus.
Raws li daim ntaub thaiv pob zeb diamond vibrating thiab nws txoj kev tsim khoom uas tau qhia hauv qhov kev tsim kho tshiab no, ib lub pwm uas muaj qhov chaw nkhaus tau muab, thiab lub zog tsis sib xws (tsis sib xws) uas ua rau cov roj sib cais dhau los ntawm sab saum toj ntawm lub pwm kom tsim kom muaj qhov kub siab los ua kom lub pwm sov kom qhov chaw ntawm lub pwm muaj qhov sib faib kub tsis sib xws.
Piv txwv li nrog
1. Cov hlau tiv taus cua sov yog qhov chaw nruab nrab (qhov chaw muaj zog siab tshaj plaws), thiab qhov kev sib xyaw ua ke ntawm cov tshuaj tiv thaiv qhia txog kev faib tawm ntawm lub nplhaib tsis sib xws.
2. Vim yog cov teebmeem ntawm qhov ntev ntawm lub zog, qhov dav, thiab cov nthwv dej sawv ntsug rau ntawm cov plasma uas raug txhawb los ntawm lub zog zaus siab, qhov kev sib sau ua ke ntawm cov tshuaj reacting ua rau muaj cov duab kheej kheej nrog kev faib tawm tsis sib xws.
3. Lub zog nplaim taws ploj mus sab nraud ntawm thaj chaw nruab nrab, thiab qhov kev sib sau ua ke ntawm cov tshuaj tiv thaiv ua rau muaj kev faib tawm sib txawv tsis sib xws.
Qhov kub thiab qhov concentration ntawm cov tshuaj tiv thaiv uas tsim los ntawm lub zog saum toj no lwj sai sai rau sab nraud ua ntu zus; yog li ntawd, qhov chaw sib txawv ntawm cov pwm sib cuag nrog thaj chaw sib txawv ntawm cov tshuaj tiv thaiv kom loj hlob cov yeeb yaj kiab pob zeb diamond nrog cov qauv sib txawv thiab cov tuab sib txawv, ua rau cov khoom siv pob zeb diamond tsis sib xws. (tsis sib xws) cov yam ntxwv ntawm kev co, xws li tuab lossis tawv muaj kev faib tawm tsis sib xws, thiab tom qab ntawd cov yeeb yaj kiab pob zeb diamond nyias raug tshem tawm ntawm pwm los tsim cov yeeb yaj kiab pob zeb diamond vibration. Cov xwm txheej ntawm cov khoom siv pob zeb diamond suav nrog micro-crystal (Micro-crystal), nano-crystal (Nano-crystal) thiab lwm yam.
Raws li cov yeeb yaj kiab vibrating pob zeb diamond uas tsim los ntawm kev tsim kho tshiab no, nws qhov nyuaj thiab tuab tsis sib xws, thiab qhov nyuaj ntawm thaj chaw nruab nrab yog siab, qhov nyuaj ntawm thaj chaw ntug yog qis, thiab qhov tuab ntawm thaj chaw nruab nrab yog loj, thiab qhov tuab ntawm thaj chaw ntug yog me me. Cov yam ntxwv ntawm kev co ntawm txhua qhov raug cuam tshuam los ntawm qhov nyuaj thiab Cov nyhuv ntawm qhov tuab muaj cov zaus ntuj sib txawv, yog li ntawd lub diaphragm pob zeb diamond tuaj yeem muaj bandwidth loj dua.
