Kev sib raug zoo ntawm lub suab zoo thiab cov khoom siv
(1) Nruab nrab qis cone:
① Paper cone: Lub suab bass thaj tsam yog nplua nuj thiab sib sib zog nqus, feem ntau siv nyob rau hauv nruab nrab mus rau tsawg zaus:
Qhov zoo: Lub suab ntuj, tus nqi qis, zoo rigidity, cov khoom siv lub teeb, siab rhiab heev;
Disadvantages: Tsis zoo noo noo tsis kam, yooj yim deformation, thiab tsawg deg hardness.
② Plastic cone: Bextene (polystyrene);
③ PP lub khob hliav qab:
Qhov zoo: Nws muaj cov yam ntxwv ua kom tsis zoo, tsis cuam tshuam los ntawm ya raws, yog lub teeb thiab tawv, tuaj yeem ua rau ntau qhov ntau thiab tsawg, thiab muaj cov yam ntxwv zoo ntawm lub cev thiab lub suab;
Qhov tsis zoo: Nws tsis yooj yim rau kev ua raws thiab muaj "yas" tsw hauv lub suab.
④ Hlau cone: feem ntau yog siv rau cov ntses bass thaj tsam, feem ntau yog ua los ntawm magnesium thiab txhuas (thiab lawv cov alloys) cov ntaub ntawv, uas yog hnyav, muaj zog, thiab muaj kev ua haujlwm tsis zoo.
⑤ Silk thiab linen cone:
Qhov zoo: Kev ntxhib los mos, kev ua tau zoo hauv cov suab paj nruag mos thiab lub teeb;
Disadvantage: Tsis muaj zog thiab poob siab.
⑥ Fiberglass, bulletproof ntaub (Kevlar): tseem hu ua woven cone:
Qhov zoo: zoo suab zoo, zoo stability, thiab tsis tshua muaj kev cuam tshuam ib puag ncig;
Disadvantages: Cov txheej txheem tsim khoom yog complex thiab tus nqi siab.
⑦ Lwm cov yas: TPX, HD-A, HD-I, Neoflex (focal), Bextene.
(2) Diaphragm (siab pitched):
① Organic zaj duab xis: feem ntau yog siv rau cov neeg hais lus siab coaxial, nws tuaj yeem tiv taus lub zog qis.
② Hlau zaj duab xis: Siab pitched thiab meej, ua tau zoo dua li zaj duab xis lo lo ntxhuav ntawm lub zog siab.
③ Silk zaj duab xis: Lub suab zoo tshaj plaws, tshwj xeeb tshaj yog thaum lub zog qis.
3) Ncej:
Muaj nuj nqi:Ua kom cov qauv siv tshuab ruaj khov thiab muab qhov tseeb txav rau lub diaphragm
① Hlau ncej: Tus nqi qis.
② Steel ncej: ua los ntawm kev kub siab, nrog tus nqi qis thiab siab hardness, feem ntau siv rau cov neeg hais lus bass.
③ Aluminium magnesium alloy tuag-casting: Zoo durability, anti resonance, zoo nkauj tsos, thiab tus nqi siab.
(4) Lub suab coil:
① Tweeter:
Aluminium hlau: lub teeb yuag, nrog cov lus teb zoo heev.
Copper hlau: Muaj zog load-bearing muaj peev xwm thiab siab durability.
② Nruab nrab thiab qis zaus:
Copper hlau: Nrog lub peev xwm thauj khoom siab thiab kev ua haujlwm zoo, nws yog feem ntau ncig hauv cov duab thiab kuj muaj hexagonal thiab duab plaub. Ob qhov tom kawg tuaj yeem ua kom cov cua sov ua kom zoo dua qub thiab txhim kho lub zog nqa lub peev xwm.
(5) Lub suab coil tuav:
Aluminium ntawv: zoo cua sov dissipation, hnav, thiab tsis yooj yim deformed.
KLSV epoxy resin board: waterproof thiab insulated, nrog zoo load-bearing muaj peev xwm.
(6) Magnet:
① Ferrite: ntim loj, tus nqi qis, ntau yam.
② Neodymium hlau nplaum: Cov khoom sib nqus yog 7 npaug ntawm ferrite, tab sis nws tsis ruaj khov thiab yooj yim magnetized.
③ Strontium magnetic: kev ua haujlwm siab, me me, feem ntau yog siv rau lub suab nrov.
(7) Damper: tseem hu ua kab laug sab,
① paj rwb ntaub: muaj kev ruaj ntseg zoo, tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias, yog pheej yig, tab sis tsis zoo smoothness.
② Polyimide fiber ntau: muaj qhov zoo rigidity, muaj zog tsim kua muag tsis kam, zoo noo noo tsis kam, tsis yooj yim deformed, muaj qhov kub thiab txias, thiab kim.
③NOMEX: qhov zoo tshaj plaws kub-kub thiab nplaim-retardant fiber ntau tsim thiab muab tso rau hauv kev siv los ntawm DuPont hauv xyoo 1960. Nws yog resistant rau feem ntau acids thiab muaj zoo stability rau alkalis. Nws yog dav siv hauv kev lag luam tub rog thiab hluav taws xob thiab yog qib H-qib cov khoom siv rwb thaiv tsev zoo heev.
