Ho sebelisa Round NdFeb ho Electroacoustic

Tlhaloso e Khutšoanyane:

Round NdFeB (limmanete tse sa feleng) li na le litšebeliso tse ngata ho electroacoustics.Li ka sebelisoa e le makenete ho libui le li-microphone, tse thusang ho fetolela matla a motlakase hore e be molumo kapa ka tsela e fapaneng.Matla a khoheli a matla a makenete a NdFeB a ka thusa ho ntlafatsa ts'ebetso le ts'ebetso ea libui le li-microphone.Ntle le moo, li ka sebelisoa hape ho li-unit tsa bakhanni ka li-headphone le lisebelisoa tse ling tsa molumo ho ntlafatsa ts'ebetso le boleng ba molumo oa lisebelisoa tsa molumo.

Re sebelisa foromo ea no-dysprosium ho lihlahisoa tsa boemo bo tlase bakeng sa bareki ho fokotsa litšenyehelo.Re na le foromo e tsitsitseng e ka etsoang lihlahisoa tse tlase tsa mocheso o tlase.E fokotsa litšenyehelo mme e eketsa ts'ebetso e eketsehileng bakeng sa bareki ba nang le taolo e tiileng ea ho mamella ts'ebetsong le ho roala ho ea ka litlhoko tse fapaneng tsa bareki ho netefatsa botsitso ba tšireletso ea plating ka nako e le 'ngoe, ho kenyelletsa le ho fafatsa letsoai, ho tlama matla, ho kopanya li-colloid joalo-joalo. .

Lihlahisoa tse pota-potileng li na le tšekamelo ea ho lahleheloa ke likhutlo nakong ea tlhahiso.Kahoo re na le lisebelisoa tsa tlhahlobo tse felletseng tsa ho mamella ponahalo, tse ka netefatsang bofokoli ba sehlahisoa ka har'a mefuta e laolehang le ho qoba lihlahisoa tse nang le phoso ha re sebelisa ts'ebetso.

Mabapi le ho feto-fetoha ha flux, re netefatsa hore sebōpi sa sintering se tsitsitseng se lumellana le taolo ea ts'ebetso ea makenete, le lisebelisoa tsa tlhahlobo tse felletseng tsa makenete ho thibela lihlahisoa tse fokolang tsa makenete hore li se ke tsa phallela ho bareki.Mabapi le sephutheloana sa magnetization, k'hamphani ea rona e na le lisebelisoa tsa othomathike tsa coding magnetization ho thibela basebetsi ho senya tefiso ea makenete.

Mabapi le taolo ea ho pepa, palo e kholo ea mechine e sehang e nang le mela e mengata, li-slicing units, basebetsi ba hōlileng tsebong ba sebetsang ka theknoloji, ts'ebetso e phethahetseng ea tlhahiso ea lihlahisoa, mohato o mong le o mong oa ts'ebetso ea lihlahisoa le tlhahiso e ka fumana maikutlo a tsoelo-pele ka nako leha e le efe, mohala oa tlhahiso ea lihlahisoa tsa cylindrical, ho netefatsa litlhoko tsa taolo ea bareki bakeng sa ho fana ka lihlahisoa, hammoho le tsoelo-pele e laolehang ea tlhahiso.
