Tus 10-nti nruab nrab sab nrauv muaj co nrog 50mm dome-top midrange diaphragm nrog ntuj fiber ntau braided tshwj xeeb damping rau ntuj thiab yog suab. High-power aluminium skeleton suab coil nrog tooj liab-clad txhuas winding, muaj hwj huam ntau zog, ua theem resonant qauv, txo Q tus nqi ntawm lub unit resonance ncov, txo distortion, thiab widening cov lus teb muaj tsawg-zaus.
Lub tshuab dual-hlau nplaum uas muaj kab-sib nqus qhov sib npaug, qhov teeb meem tsis sib haum xeeb, ua kom muaj siab, ua kom tsis muaj teeb meem. Cov txheej txheem uas tsis tshua muaj-distortion theem ntawm tus qauv muaj qhov tso rau hauv qhov tob hauv 10-nti nruab nrab ntawm lub pob ntseg nrov diaphragm, thiab thaum tawm ntawm lub aperture yog lub ntim loj, muaj zog, tsis muaj teeb meem kaw tsis tau rov qab. Kev sib koom tes muaj xws li diaphragm, lub suab coil, thiab ib qho me me ntawm huab cua ntim qab lub diaphragm. Qhov qhib lub qhov thiab lub hau npog npog lub cev yog cov kab hluav taws xob uas muaj zog. Cov cua ntim hauv lub qhov dav tawm qhov pom tias lub sij hawm ntawm lub qhov qhib qhov chaw nyob ze ntawm qhov chaw nruab nrab ntawm qhov kev nkag siab ntawm tus impedance curve. Txo cov amplitude ntawm 10-nti nruab nrab cov lus qhia hauv no qhov qhab nia kom zoo rau qhov kev sib txawv. Lub zog hauv qab lub nplais qhwv muaj zog tuaj yeem ua rau cov kab noj muaj zog, yog li cov lus tso tawm suab yuav ua rau lub suab qis tsis zoo, thiab sib npaug rau cov khoom siv ntawm Acoustic ze ntawm 24db / oct. Lub lim, vim hais tias lub ntsiab ntawm 10-nti nruab nrab sab nraud muaj tshwm sim nyob rau hauv qhov chaw ntau zaus, dhau ntawm cov txheej txheem uas tsis tshua muaj-distortion phase-conducting resonant, qhov distortion ntawm cov zaus no tuaj yeem nyuaj siab, kom tus neeg hais lus yuav tsum tsawg-distortion ua hauj lwm hauv lub xeev ntawm tag nrho cov haujlwm ua haujlwm. Tsis tas li ntawd, txawm tias qhov qis ntu tsawg ntawm lub lim tsis huv, tus neeg hais lus tsis tuaj yeem tawm cov suab vim yog qhov qis-distortion theem-conduction resonant qauv acoustic filtering.
Hauv kev soj ntsuam ntawm ntau qhov kev qhia, feem ntau ntawm cov twj paj nruag thiab tib neeg cov suab lus raug muab faib rau hauv nruab nrab lub suab qis hauv qab 4000 Hz, yog li cov lus sib dhos ntawm tag nrho nruab nrab suab ntu yog siab heev. Nyob hauv thaj chaw ntawm electroacoustic tshuab, neeg feem ntau siv cov 1 kHz teeb liab feem ntau siv los soj ntsuam li qhov chaw, thiab qhov sib txawv ntawm ib qho octave hauv qab 1 kHz thiab ob octaves saum toj 1 kHz yog 500 ~ 4000 Hz ua qhov ntev zaus. Feem ntau peb xav kom tus 10-ntu nruab nrab cov lus sib txuas lus kom muaj qhov sib txawv ntawm cov lus saum toj no, thiab cia siab tias nws muaj peev xwm ua tau zoo li tus choj kom zoo, thiab qhov chaw tsis muaj zog thiab lub siab ua haujlwm muaj qhov rhiab heev thiab suab. Zoo sib xws, yog li peb hais tias qhov kev ua yeeb yam ntawm cov chav IF yuav muaj feem cuam tshuam rau kev kawm tag nrho ntawm tus neeg hais lus tag nrho. Vim li no, txoj kev xaiv ntawm chav 10-inch midrange speaker yog nyob rau hauv txoj haujlwm tseem ceeb tshaj plaws hauv kev xaiv ntawm txhua chav hais lus.
Qhov tseeb, nws yog ib qho nyuaj ua kom tus 10-nti nruab nrab hais lus uas ua tau raws li cov kev cai saum toj no. Nws tsis yog ib txoj hauj lwm yooj yim los xaiv ib lub chav pabcuam theem nrab uas ua tau raws li cov cai no. Los ntawm cov kev tsis txawj ntawm 10-nti nruab nrab cov neeg hais lus, feem ntau cov kev siv ntau 10-nti nruab nrab ntawm cov khw muag khoom muaj peev xwm ua tau raws li cov lus teb rau cov lus teb saum toj no, tab sis qhov teeb meem nyob hauv lo lus "zoo". Raws li peb tau hais ua ntej, feem ntau ntawm cov lus qhia ua tau zoo raws li tus 10dB nco hauv nruab nrab suab siab ntawm cov lus hais lus. Qee qhov 10-inch midrange speaker units, tab sis qhia txog lawv cov ntau zaus, tsis yog Nws tau qhia tias nws qhov kev ntsuas ntau yog ntsuas raws li seb muaj pes tsawg tus decibels qhov yuam kev, uas yog yooj yim rau ntau cov neeg siv tsis to taub. 10-inch mid-range speaker chav muaj kev zoo ib yam li cov lus qhia tsis zoo sib xws li 10-nti nruab nrab cov lus sib tham, thiab qee zaus nws qhov nquag muaj zog dua li qhov ua tsis zoo nkauj 10-inch midrange speaker , tab sis zoo HOM TSIS TAU muaj cov lus teb nyob rau hauv nws qhov ntau zaus, thiab qhov ua tau zoo yog IFI nthuav tawm ntau yam tseem ceeb hauv nonlinear distortions. Yog tias muaj ob hom sib txawv hauv cov chav nruab nrab, feem ntau qhov sib txawv ntawm ob lub chav nruab nrab yog ze heev, thiab ib lub chav nruab nrab muaj qhov tsis muaj cuab yeej qhib siab tshaj plaws nyob rau hauv txhua qhov ntau yam, uas qhia tau tias nws lub suab siab tseem ceeb thiab tsis sib thooj ntawm nonlinear yog me me; Lwm YOG HAIS TSIS MUAJ ntau yam muaj qhov sib txawv thiab cov kwj ha ntawm ntau qhov ntau yam. Txawm hais tias nws txoj kev siv ntau yam zoo los kuj txaus siab, nws yog qhov tseeb tias kev siv chav ntawm IF no tsis ua raws li qhov yuav tsum tau muaj rau cov lus hais lus Hi-Fi.
Nyob rau hauv xyoo tas los, ntau tus kws hais lus tuam txhab nyob hauv tsev thiab lwm lub teb chaws tej zaum kuj siv ncaj qha qee tus neeg hais lus me me uas tsis tshua muaj siab ua cov lus hais ua ke. Vim hais tias cov lus tso tawm tsis txaus siab ntawm cov lus qhia tsawg tsawg tshaj 100 Hz, qhov txo qis ntawm qhov feem ntau ntawm cov neeg ua haujlwm hauv chav nruab nrab yuav raug txo kom tsawg, thiab cov kev sib txuas lus ntawm cov neeg tuaj yeem sib txuas lus tau zoo tuaj. Tiam sis, muaj ib qho taw qhia uas yuav tsum tau muab sau tseg. Yuav kom txo nws lub zog tsis txaus, lub woofer muaj lub paj qhib rau ntawm nws lub phiab. Thaum twg peb siv lub woofer ua ib qho chaw uas tsis tshua muaj neeg caij nyoog, peb yuav tsum tso ib sab nyob tom qab ntawm woofer. Txhaws cov kab noj nraub qaum nrog ib lub ntim thiab sau kom txaus rau cov khoom siv suab nrov. Qhov no tuaj yeem tiv thaiv lub suab tsis ua haujlwm sab qaum sab ntawm lub khob tawm ntawm lub suab tsis ua haujlwm sab nraub qaum ntawm lub xov tooj cua ntawm tus neeg hais lus, thiab tseem tuaj yeem tiv thaiv kom tsis muaj teeb meem ntawm qhov qub woofer ntau tom qab lub chamber rear yog ntsia.
