Titanium alloy diaphragm rau cov khoom siv suab
Nyob rau hauv lub suab teb, lub diaphragm, raws li lub hauv paus ntsiab lus rau lub suab reproduction, ncaj qha cuam tshuam lub clarity, dynamic ntau yam, thiab timbre ntawm lub suab teeb liab. Titanium alloy diaphragms, nrog rau lawv cov khoom tshwj xeeb ntawm lub cev thiab kev ua haujlwm thev naus laus zis, tau maj mam dhau los ua "tus qauv kub" rau siab - zaus units hauv siab - khoom siv suab kawg. Lawv daim ntawv thov tsis tau tsuas yog hloov kho lub sonic ciam teb ntawm cov tsoos hlau diaphragms tab sis kuj qhia tau hais tias irreplaceable tus nqi nyob rau hauv kev saib xyuas thiab kev ua yeeb yam hauv tsev.
Lub ntsiab kom zoo dua ntawm titanium alloy diaphragms stems los ntawm lawv ob tug yam ntxwv ntawm "lub teeb yuag thiab siab rigidity." Piv rau cov tsoos aluminium alloy diaphragms, titanium alloys muaj qis dua thiab muaj zog dua. Cov cuab yeej ntawm lub cev tsis sib xws no tso cai rau lawv tswj hwm qhov tsis tshua muaj zog thaum lub sij hawm siab - zaus vibrations thaum khaws cia lub diaphragm cov duab ruaj khov. Piv txwv li, tom qab ib tug zoo-paub suab hom tau txais ib tug titanium alloy diaphragm nyob rau hauv nws tweeter, nws siab - zaus teb ntau yam nthuav dav los ntawm 20kHz mus rau 40kHz, thiab tus distortion tus nqi txo mus rau hauv qab 0.05%. Qhov no txhais tau hais tias thaum ua si txoj hlua solos hauv cov suab paj nruag classical, qhov hloov maj mam vibrations ntawm cov hlua thiab cov suab sib txhuam ntawm huab cua tuaj yeem raug ntes tau, thiab cov neeg mloog tuaj yeem pom qhov kev hloov ntawm hneev siab. Qhov tshwj xeeb tshaj tawm no ntawm siab - cov ntsiab lus zaus yog qhov laj thawj tseem ceeb vim li cas titanium alloy diaphragms thiaj li nyiam nyob rau hauv kev saib xyuas kev ua haujlwm.
Kev tiv thaiv corrosion thiab lub neej ntev ntawm titanium alloys ntxiv dag zog rau lawv txoj kev ntseeg siab hauv qhov chaw hnyav. Cov hlau diaphragms ib txwm ua rau oxidation thiab xeb hauv cov av ntub lossis siab - qhov kub thiab txias, ua rau lub suab nrov thiab siab - zaus attenuation. Titanium alloys, txawm li cas los xij, muaj tshuaj lom neeg ruaj khov, tso cai rau lawv kom muaj kev ruaj ntseg hauv qhov kub thiab txias xws li -40℃txog 80℃. Cov ntaub ntawv ntsuam xyuas los ntawm lub tsheb lub chaw tsim khoom qhia tau hais tias tom qab 1000 teev ntawm kev ua haujlwm tas mus li, cov lus teb zaus nkhaus ntawm lub tweeter nruab nrog titanium alloy diaphragm yuav luag zoo kawg nkaus phim nws lub xeev thawj zaug, thaum lub aluminium alloy diaphragm nthuav tawm 5% zaus teb hloov nyob rau hauv tib lub sijhawm. Qhov kev ua kom zoo dua qub no ua rau titanium alloy diaphragms qhov kev xaiv zoo tshaj plaws rau sab nraum zoov lub suab, lub tsheb lub tshuab, thiab lwm yam kev siv uas yuav tsum tau ua kom ntev mus ntev rau cov cheeb tsam nyuaj.
Txawm hais tias titanium alloy diaphragms muaj nyob ze rau - zoo meej siab - zaus ua haujlwm, lawv cov xim "hlau" muaj keeb kwm dhau los ua ib qho kev cuam tshuam rau lawv txoj kev saws me nyuam. Thaum ntxov ib zaug - txheej titanium alloy diaphragms raug kev txom nyem los ntawm tsis txaus damping, yooj yim ua ib tug hnyav "hlau whistle" thaum ntaus suab paj nruag pop. Yuav kom daws tau qhov teeb meem no, engineers tau tsim cov txheej txheem sib xyaw tshuab. Ua ib qho khoom lag luam titanium sandwich diaphragm ua piv txwv, nws siv cov qauv tsim ntawm ob txheej ntawm ultra-thin titanium alloy sandwiched nrog honeycomb aluminium khoom. Qhov no tuav lub siab rigidity ntawm titanium alloy thaum lub honeycomb qauv ntawm txhuas absorbs ntau zog vibration, ua rau lub damping coefficient mus rau ntau tshaj peb npaug ntawm cov tsoos hlau diaphragms. Hauv kev sim mloog tiag tiag, qhov sib xyaw diaphragm no ua rau muaj kev sib sib zog nqus thiab ua pa nrov dua thaum ua suab nrov, thiab cov zaus siab tsis muaj "ntse," tab sis hloov mus rau qhov zoo nkauj zoo nkauj.
Los ntawm kev tsim khoom, kev ua haujlwm nyuaj ntawm titanium alloy diaphragms deb tshaj li cov hlau zoo tib yam. Txawm hais tias titanium muaj ductility zoo dua li beryllium, qhov teeb meem kev ntxhov siab tawg thaum lub sij hawm kub nias tseem yuav tsum tau kov yeej thaum tsim cov ntses bass thaj tsam loj. Lub siab -kawg suab hom tau siv ob xyoos los tsim lub 12-inch titanium alloy woofer diaphragm, mastering cov txheej txheem titanium annealing. Los ntawm kev tswj xyuas qhov kub thiab txias txias, lawv txo qhov kev ntxhov siab sab hauv ntawm daim ntawv titanium kom qis dua 0.1 MPa, thaum kawg ua tiav cov diaphragm uas tseem tsis tau hloov pauv txawm tias raug lub suab siab ntawm 110 dB. Qhov kev sib tw rau cov kev txwv ntawm thev naus laus zis ncaj qha propelled qhov nthuav dav ntawm titanium alloy diaphragms los ntawm high-frequency units mus rau daim ntawv thov thoob plaws tag nrho ntau zaus.
Niaj hnub no, titanium alloy diaphragms tsis nyob rau hauv siab -kawg suab lag luam. Raws li cov neeg siv khoom xav tau lub suab zoo dua, ntau dua thiab ntau dua nruab nrab -cov neeg hais lus tau txais titanium alloy tweeters, ua ke nrog ntawv lossis carbon fiber woofers, tsim kom muaj qhov sib npaug ntawm cov lus teb. Qhov kev sib xyaw ua ke no khaws cia qhov tseeb ntawm titanium alloy nyob rau hauv lub siab zaus thaum nruab nrab ntawm cov xim hlau xim los ntawm kev ntxhib los mos ntawm qhov tsawg- zaus, tso cai rau cov neeg siv khoom zoo tib yam kom muaj kev tshaj lij- qib suab zoo ntawm tus nqi pheej yig. Nyob rau hauv lub neej yav tom ntej, nrog rau kev loj hlob ntxiv ntawm titanium alloy ua technology, nws cov nqi yuav tsum txo qis ntxiv, thiab titanium alloy diaphragms yuav dhau los ua tus qauv hauv kev lag luam suab, coj mus rau lub sijhawm tshiab ntawm "siab-} kev ncaj ncees" lub rooj sib hais rau ntau tus neeg nyiam suab paj nruag.
