Cov Lus Nug Feem Ntau

Q: Vim li cas cov kws ua suab thiaj nyiam siv cov hlau nplaum uas muaj nplhaib dua li cov hlau nplaum disc rau cov neeg hais lus?

A: Cov hlau nplaum nplhaib xa 15-22% siab dua BL-factor ntawm kev faib tawm flux-distribution hauv lub suab-coil cua-gap, ua tiav ≥92 dB / W / m rhiab heev piv rau 87-88 dB / W / m rau kev sib npaug ferrite-disc-magnet tsim. Lub hauv paus bore ua rau kev koom ua ke pole-piece rau dual-magnetic-circuit architectures, thawb THD qis dua 1% (@ 1 W / 1 kHz). Lub bore kuj tsim cov channel cua ntuj rau kev thermal dissipation - tseem ceeb rau cov kws tshaj lij-audio loudspeakers khiav saum toj no 200 W lub zog tas mus li.

Q: Qib NdFeB zoo tshaj plaws rau cov hlau nplaum hais lus yog dab tsi?

A: N42 xa qhov sib npaug zoo tshaj plaws rau feem ntau cov haujlwm suab, sib npaug remanence (1.3 T), lub hauv paus thermal-stability (80 ° C siab tshaj plaws ua haujlwm-kub) thiab tus nqi lag luam. Rau qhov chaw-txwv compact kho vajtse, N48 lossis N52 xa 15-20% siab dua flux-density tab sis xav tau kev tswj hwm thermal-kev ceev faj. Cov kws tshaj lij-audio loudspeakers pom lub suab-coil kub siab dua 150 ° C yuav tsum xa SH- lossis UH-suffix high-kub qib kom tiv thaiv kev demagnetisation tsis rov qab.

Q: Lub nplhaib-magnet geometry txo qhov kev cuam tshuam ntawm lub loudspeaker li cas?

A: Lub nplhaib-magnet geometry tsim cov magnetic-field symmetric uas tseem sib xws thoob plaws tag nrho cov suab-coil-excursion ntau yam. Disc-magnets tsim cov flux-gradients ze ntawm ntug. Homogeneous magnetic-field txo qhov sib txawv ntawm BL-product thaum lub sijhawm txav mus los ntawm lub khob hliav qab thiab ncaj qha suppresses tag nrho-harmonic-distortion. Rau dual-stacked-ring dual-magnetic-circuit assemblies, THD tuaj yeem nyob qis dua 5% @ 100 Hz / 500 W, thaum disc-magnet sib npaug feem ntau sau npe 8-12% THD nyob rau hauv cov xwm txheej zoo sib xws.

Q: Cov hlau nplaum nplhaib puas tuaj yeem siv tau rau hauv subwoofers thiab cov lus qhia twg yog cov lus pom zoo?

A: Yog. Cov hlau nplaum nplhaib yog cov khoom siv tseem ceeb hauv cov qauv tsim subwoofer niaj hnub, tshwj xeeb tshaj yog cov teeb tsa dual-magnetic-circuit siv ob lub nplhaib N42 lossis N45 sib dhos kom ua kom BL-factor siab tshaj plaws. Rau 12-nti subwoofers, cov yam ntxwv ib txwm muaj: OD 110-130 hli, ID 55-65 hli, tuab 15-20 hli ib lub nplhaib. Lub hauv paus nruab nrab haum rau lub ncej-piece thiab ua rau lub suab-coil txias. Fullzen Technology tsim cov hlau nplaum subwoofer-ring-magnets txog li 200 hli OD, ua tiav nrog kev sim tag nrho qhov ntev- thiab magnetic-property.

Q: Cov neeg yuav khoom yuav tsum xav tias yuav tsum muaj MOQ dab tsi rau cov hlau nplaum hais lus uas tau los ntawm Tuam Tshoj?

A: Cov qauv txheem xa khoom tsis pub dhau 7-10 hnub yam tsis muaj qhov tsawg kawg nkaus. Cov qauv geometries uas xav tau cov cuab yeej tshiab feem ntau nqa MOQ 500-1000 pcs rau thawj zaug tsim khoom. Kev tsim khoom loj-MOQ ntau yam 2000-5000 pcs nyob ntawm qhov nyuaj ntawm ib feem.Kev Siv Tshuab Fullzentswj cov khoom siv raw kom txo qhov kev hloov pauv ntawm lub sijhawm ua khoom.
