Iimagnethi zeringi yeNeodymium zisebenza ngcono kuneemagnethi ezimile okwediski kwiinkqubo zesithethi. Ukusasazwa kweflux okulungiselelweyo kunika i-BL factor ephezulu nge-15-22%, ifikelela kwi-92 dB/W/m, xa kuthelekiswa ne-87-88 dB/W/m kwizisombululo zeferrite ezifanayo. Imilo yeringi inika ukugubungela kwe-magnetic field elinganayo kuyo yonke i-voice coil yokuhamba, ityhala i-total harmonic distortion (THD) ngaphantsi kwe-1% kwi-1 W / 1 kHz. I-central bore ivumela ukuhlanganiswa kwe-pole piece kwizakhiwo ze-dual magnetic circuit kwaye iphucula ukusasazwa kobushushu - inzuzo ebalulekileyo kwizixhobo ze-audio zobungcali eziphatha amandla aqhubekayo angaphezu kwama-200 W.

Eli nqaku ligxile kubunjineli lisebenzisa idatha yokusebenza elinganisiweyo ukuchaza iingenelo ze-neodymium ring magnet geometry kuyilo lwesandisi-lizwi:

Yintoni Eyenza Iimagnethi Zeringi Zahluke Kwiimagnethi ZeDiski kuYilo Lwesandisi-lizwi?

Ijiyometri yemagnethi inefuthe elikhulu ekusebenzeni kwe-acoustic kunokuba abayili abaninzi becinga. Nangona iimagnethi zeringi zibonakala zahlukile kwiimagnethi zediski kuphela ngomngxuma ophakathi, olu phawu lomzimba lutshintsha ngokusisiseko umda wokusebenza okuphezulu kwesekethe yemagnethi.

I-Physics yeRing Geometry: Ukusasazwa kwe-Symmetric Flux

Inzuzo ephambili ebonakalayo yeemagnethi zeringi ikukulingana kwe-magnetic flux. Kwiimagnethi zediski, i-flux iphuma embindini ize yonakale iye emaphethelweni, idala amandla angalinganiyo kwi-voice coil kwi-excursion. Kwi-ring magnet designs, i-flux igxila ngaphakathi kwendawo ye-annular phakathi kweedayamitha zangaphakathi nezangaphandle kwaye yenza i-axial magnetic field efanayo kakhulu.

• Imagnethi emile okwediski: uxinano lweflux luyehla nge-15-25% ukusuka embindini ukuya emaphethelweni; i-voice coil ifumana amandla angalinganiyo kwiindawo ezinkulu zokuhamba

FAQ

Q: Kutheni iinjineli zezandi zikhetha iimagnethi zeringi kuneemagnethi zediski kwizandisi-lizwi?

A: Iimagnethi zeringi zinika i-BL factor ephezulu nge-15-22% ngokusasazwa kwe-homogeneous flux ngaphakathi kwesithuba somoya we-voice coil, nto leyo efikelela kwi-≥92 dB/W/m xa kuthelekiswa ne-87-88 dB/W/m kwi-ferrite disc magnet equivalent builds. I-central bore ivumela ukuhlanganiswa kwe-pole piece kwi-dual-magnetic circuit architectures, ityhala i-THD ngaphantsi kwe-1% (@ 1 W / 1 kHz). I-bore ikwadala imijelo yendalo yokuhamba komoya ukuze kusasazeke ubushushu -- ibalulekile kwi-loudspeakers zobungcali ezisebenza ngaphezu kwamandla aqhubekayo angama-200 W.

Q: Ngowuphi umgangatho we-NdFeB ongcono kakhulu kwiimagnethi zeringi yesipikha?

A: I-N42 ibonelela ngebhalansi efanelekileyo kwiiprojekthi ezininzi zesandi, ukulinganisela ukubuyiselwa kwakhona (1.3 T), ukuzinza kobushushu obusisiseko (ubushushu obuphezulu bokusebenza obuyi-80 °C) kunye neendleko zorhwebo. Kwizixhobo ezincinci ezilinganiselweyo ze-compact, i-N48 okanye i-N52 ibonelela ngoxinano oluphezulu lwe-flux oluyi-15-20% kodwa ifuna ulawulo olucokisekileyo lobushushu. Izithethi zesandi zobungcali ezibona amaqondo obushushu e-voice coil angaphezu kwe-150 °C kufuneka zisebenzise amanqanaba aphezulu obushushu e-SH- okanye e-UH ukuthintela ukususwa kwemagnethi okungenakuguqulwa.

Q: I-geometry ye-ring-magnet inciphisa njani ukuphazamiseka kwesandisi-lizwi?

A: I-geometry ye-ring magnet ivelisa i-symmetric magnetic field ehlala ifana kuluhlu olupheleleyo lwe-linear voice coil excursion. Ii-disc magnets zivelisa ii-flux gradients kufutshane nemiphetho. I-homogeneous magnetic field inciphisa ukuguquguquka kwemveliso ye-BL ngexesha lokuhamba kwe-cone kwaye icinezela ngokuthe ngqo ukuphambuka kwe-harmonic iyonke. Kwiindibano zesekethe ze-dual magnetic ezine-stacked ring, i-THD inokuhlala ngaphantsi kwe-5% @ 100 Hz / 500 W, ngelixa ii-disc magnet equivalent zihlala zibhalisa i-8% THD phantsi kweemeko ezifanayo.

Q: Ngaba iimagnethi zeringi zingafakwa kwii-subwoofer kwaye zeziphi iinkcukacha ezicetyiswayo?

A: Ewe. Iimagnethi zeringi zisetyenziswa kakhulu kwiidesign ze-subwoofer zanamhlanje, ingakumbi iiseti zesekethe ze-magnetic ezimbini ezisebenzisa iiringi ezimbini ze-N42 okanye ze-N45 ukuze kwandiswe i-BL factor. Kwii-subwoofer ze-intshi ezili-12, iiparameter eziqhelekileyo: I-OD yi-110-130 mm, i-ID yi-55-65 mm, ubukhulu yi-15-20 mm ngeringi nganye. I-bore ephakathi ithwala isiqwenga se-pole kwaye ivumela ukupholisa i-convective voice coil. I-Fullzen Technology yenza iimagnethi zeringi ze-subwoofer ukuya kuthi ga kwi-200 mm OD, epheleleyo ngovavanyo lwepropathi olupheleleyo nolwe-magnetic.

Q: Yintoni i-MOQ abathengi abafanele bayilindele kwiimagnethi zesipikha ezenziwe ngokwezifiso ezivela eTshayina?

A: Iisampulu ze-standard spec zithunyelwa zingadlulanga iintsuku ezi-7-10 ngaphandle kobuninzi be-odolo. Iijometri ezenziwe ngokwezifiso ezifuna izixhobo ezintsha zihlala zithwala ii-MOQ ezingama-500-1000 ii-pcs zokuqala zemveliso. Imveliso yobuninzi i-MOQ isukela kwii-pcs ezingama-2000-5000 kuxhomekeke kubunzima benxalenye.Ubuchwepheshe beFullzenigcina impahla eluhlaza ukuze inciphise ukuguquguquka kwexesha lokuthunyelwa. Yonke impahla ethunyelwayo ixhaswa sisiqinisekiso se-ISO 9001, ukuthotyelwa kwe-RoHS / REACH kunye neengxelo zovavanyo olupheleleyo olunemilinganiselo kunye nolwemagnethi.
