1. Lawv puas muaj lawv tus kheej -tsim amplifier chips?
Tiag tiag txhim khu kev qha kev tsheb subwoofer hom tseem ceeb tshaj qhov tseem ceeb amplifier nti tsim muaj peev xwm, tsis yog tsuas yog sib sau ua ke cov khoom lag luam. Cov neeg tsim khoom nrog tus kheej- tsim muaj peev xwm tuaj yeem ua tau raws li qhov nkhaus impedance thiab cov lus teb ib ntus ntawm chav tsev subwoofer, tsis txhob cuam tshuam kev cuam tshuam. Txwv tsis pub, txawm lub siab nominal hwj chim tsuas yog ib daim ntawv; nyob rau hauv kev siv tiag tiag, nws yuav distort, overheat, thiab kaw nyob rau hauv siab dynamic ntau yam, tsis muaj peev xwm los txhawb nqa tsis tshua muaj zog - zaus zog tso zis.
2. Cov khoom siv diaphragm puas tau ua pov thawj acoustic?
Tsis txhob tsom rau cov ntsiab lus txias xws li "carbon fiber" thiab "aramid." Qhov tseem ceeb yog seb tus kws tshaj lij lub tsheb subwoofer hom tau tshaj tawm cov ntawv xeem ntawm Young's modulus thiab damping coefficient ntawm cov khoom siv diaphragm. Cov ntaub ntawv tiag tiag qhia txog cov khoom siv deformation tswj nyob rau hauv siab -frequency vibration- tsawg dhau ib qho modulus ua rau kev vibration, siab heev modulus tsis muaj elasticity; tsuas yog ib qho kev sib piv ntawm kev tshawb fawb tuaj yeem ua kom pom tseeb tob, nrawm, thiab du qis - zaus txuas ntxiv, ua rau muaj qhov tseeb, punchy bass teb.
3. Puas yog tus qauv enclosure tau dhau los ua resonance simulation?
Reputable tsheb subwoofer hom siv finite element tsom xam software thaum lub sij hawm txoj kev loj hlob theem los simulate enclosure deformation hotspots ntawm txawv frequencies, tshwj xeeb yog thickening qhov tseem ceeb kev nyuaj siab los yog embedding damping txheej. Yog tias tsis muaj cov kauj ruam no, "ntoo" lossis "yas" cov ntaub ntawv yuav nthuav tawm lub suab nrov nrov los ntawm qhov pib ntawm nruab nrab- zaus tsawg, tsis yog siv lub zog tsawg - zaus uas yuav tsum tau xa mus, tab sis kuj tseem xa cov kev vibrations rau lub cev lub tsheb, ua rau tsis muaj suab paj nruag clarity.
4. Puas yog Bluetooth audio codec txhawb LDAC/AptX?
Leej twg tseem siv tsuas yog A2DP raws tu qauv? Mainstream hom yuav tsum tau ntev dhau los suav nrog siab - kev daws teeb meem kev sib kis zoo li LDAC lossis AptX Adaptive raws li tus qauv, ua kom ntseeg tau tias cov khoom siv suab siab tshaj 16bit / 44.1kHz tsis compressed thiab poob meej thaum txuas ncaj qha rau lub xov tooj. Yog tias tsuas yog SBC tau txais kev txhawb nqa, txawm tias cov neeg hais lus zoo tshaj plaws yuav hnov zoo li lawv tab tom plam tawm, tshwj xeeb tshaj yog nyob rau hauv lub suab nrog qhov twg cov airiness thiab cov hlua overtones tau ua tiav tag nrho, ua rau lub suab qhuav thiab txheej qis - zaus suab.
5. Puas yog qhov kev hloov pauv ntawm cov khoom siv hluav taws xob puas npog tag nrho cov xwm txheej?
Tsis txhob saib dhau 12V / 24V dual-voltage automatic recognition thiab dav -ntau qhov hluav taws xob tswj kev tsim- nws ncaj qha txiav txim siab seb lub subwoofer tuaj yeem tswj hwm nws qhov kev ua tau zoo thaum lub cav pib- nres thiab tsis muaj kev cuam tshuam thaum lub roj teeb voltage fluctuates. Qee lub tsheb subwoofer kev tshaj lij tau tshem tawm cov kev tswj hwm qhov hluav taws xob ntse kom txuag tau cov nqi, ua rau muaj qhov tsis muaj zog tsawg zaus thaum lub tshuab nrawm nrawm thiab lub suab nrov tom qab thaum mloog suab paj nruag thaum nres. Qhov no "pseudo-kev sib raug zoo" tsuas yog tsis tuaj yeem tiv taus tiag tiag - lub ntiaj teb kev tsav tsheb.
