Ajụjụ Ndị A Na-ajụkarị

A: Gịnị mere ndị injinia ọdịyo ji ahọrọ ụda-magnets karịa diski-magnets maka igwe okwu?

A: Mgbaaka-magnets na-enye 15-22% BL-factor ka elu site na nkesa flux-distribution dị n'ime oghere ikuku olu-coil, na-enweta mmetụta ≥92 dB/W/m ma e jiri ya tụnyere 87-88 dB/W/m maka owuwu ferrite-disc-magnet nke yiri ya. Oghere etiti ahụ na-enye ohere ijikọta pole-piece maka nhazi sekit abụọ-magnetic, na-akpali THD n'okpuru 1% (@ 1 W / 1 kHz). Oghere ahụ na-emepụtakwa ọwa ikuku eke maka mgbasa okpomọkụ - dị mkpa maka igwe okwu ọdịyo ọkachamara na-agba ọsọ karịa ike na-aga n'ihu 200 W.

Ajụjụ: Kedu ọkwa NdFeB kacha mma maka igwe okwu mgbanaka igwe okwu?

A: N42 na-enye nguzozi kacha mma maka ọtụtụ ọrụ ọdịyo, nhazi nchekwa (1.3 T), nkwụsi ike okpomọkụ nke ntọala (oke okpomọkụ ọrụ kachasị 80 °C) na ọnụ ahịa azụmaahịa. Maka ngwaike dị obere nke oghere nwere oke, N48 ma ọ bụ N52 na-enye njupụta flux dị elu nke 15-20% mana ha chọrọ njikwa okpomọkụ nke ọma. Igwe okwu ọdịyo ọkachamara na-ahụ okpomọkụ coil dị elu karịa 150 °C ga-etinye ọkwa okpomọkụ dị elu nke SH ma ọ bụ UH iji gbochie mmebi a na-apụghị ịgbanwe agbanwe.

Q: Kedu ka geometry mgbanaka-magnet si ebelata mgbagwoju anya nke igwe okwu?

A: Ọdịdị magnetik nke mgbanaka na-emepụta symmetric magnetik nke na-anọgide otu n'ofe oke ngagharị olu-coil-njem zuru oke. Disc-magnets na-emepụta flux-gradients nso nsọtụ. Ọdịdị magnetik nke otu na-ebelata mgbanwe ngwaahịa BL n'oge mmegharị cone ma na-egbochi mgbanwe harmonic-harmonic ozugbo. Maka mgbakọ sekit abụọ-stacked-ring, THD nwere ike ịnọ n'okpuru 5% @ 100 Hz / 500 W, ebe ihe nhata diski-magnet na-edebanyekarị 8-12% THD n'okpuru ọnọdụ ndị yiri ya.

A: Enwere ike itinye magnet mgbanaka n'ime subwoofers na nkọwapụta ndị a tụrụ aro?

A: Ee. Mgbaaka-magnets bụ ihe a na-ahụkarị n'ime nhazi subwoofer nke oge a, ọkachasị ntọala sekit abụọ-magnetic-circuit site na iji mgbanaka N42 ma ọ bụ N45 abụọ a gbakọtara ọnụ iji mee ka BL-factor dịkwuo elu. Maka subwoofer 12-inch, paramita ndị a na-ahụkarị: OD 110-130 mm, ID 55-65 mm, ọkpụrụkpụ 15-20 mm kwa mgbanaka. Oghere etiti ahụ na-anabata ogwe osisi ma na-eme ka convective voice-coil dị jụụ. Fullzen Technology na-emepụta subwoofer-ring-magnets ruo 200 mm OD, zuru oke na nnwale zuru oke- na magnet-property.

A: Kedu MOQ ndị na-azụ ahịa kwesịrị ịtụ anya maka magnet mgbanaka igwe okwu omenala sitere na China?

A: A na-ebuga ihe nlele ọkọlọtọ n'ime ụbọchị 7-10 na-enweghị ọnụọgụ kacha nta nke iwu. Geometrị pụrụ iche nke chọrọ ngwaọrụ ọhụrụ na-ebukarị MOQ 500-1000 pcs maka ọsọ mmepụta mbụ.
