Nthuav dav

Hais txog seb tus neeg hais lus puas txhawb nqa ntau lub channel tib lub sijhawm, seb puas muaj qhov tso zis interface rau cov neeg hais lus puag ncig passive, seb nws puas muaj USB input function, thiab lwm yam. Tus naj npawb ntawm cov subwoofers uas tuaj yeem txuas nrog cov neeg hais lus puag ncig sab nraud kuj yog ib qho ntawm cov qauv los ntsuas qhov kev ua tau zoo ntawm kev nthuav dav. Cov interfaces ntawm cov neeg hais lus multimedia feem ntau suav nrog analog interfaces thiab USB interfaces. Lwm tus, xws li optical fiber interfaces thiab cov digital interfaces tshiab, tsis tshua muaj.

Cov nyhuv suab

Cov thev naus laus zis suab 3D uas siv ntau dua suav nrog SRS, APX, Spatializer 3D, Q-SOUND, Virtaul Dolby thiab Ymersion. Txawm hais tias lawv muaj cov txheej txheem siv sib txawv, lawv txhua tus tuaj yeem ua rau tib neeg hnov ​​​​​​cov teebmeem suab peb-seem pom tseeb. Peb thawj zaug yog qhov ntau dua. Qhov lawv siv yog txoj kev xav ntawm Extended Stereo, uas yog los ntxiv cov txheej txheem suab los ntawm lub voj voog, kom tus mloog hnov ​​​​​​tias qhov kev taw qhia suab tau nthuav dav mus rau sab nraud ntawm ob lub hais lus, kom nthuav cov duab suab thiab ua rau tib neeg muaj qhov chaw nkag siab thiab peb-seem, ua rau muaj qhov cuam tshuam stereo dav dua. Tsis tas li ntawd, muaj ob txoj kev siv tshuab txhim kho suab: active electromechanical servo technology (siv Helmholtz resonance principle), BBE high-definition plateau sound reproduction system technology thiab "phase fax" technology, uas kuj muaj qee yam cuam tshuam rau kev txhim kho lub suab zoo. Rau cov neeg hais lus multimedia, SRS thiab BBE technologies yooj yim dua rau kev siv thiab muaj cov teebmeem zoo, uas tuaj yeem txhim kho kev ua tau zoo ntawm cov neeg hais lus.

Lub suab

Hais txog lub teeb liab uas muaj qhov ntev ntev (suab nrov), feem ntau yog hais lus, lub suab nrov. Nws feem ntau nyob ntawm qhov ntev ntev. Rau lub suab uas muaj qhov ntev ntev, lub pob ntseg tib neeg teb nrog lub suab siab, thaum rau lub suab uas muaj qhov ntev ntev, lub pob ntseg tib neeg teb nrog lub suab qis. Kev hloov pauv ntawm lub suab nrog qhov ntev ntev yog qhov tseem ceeb logarithmic. Cov twj paj nruag sib txawv ua si tib lub suab, txawm hais tias lub sijhawm sib txawv, tab sis lawv lub suab zoo ib yam, uas yog, lub suab tseem ceeb ntawm lub suab zoo ib yam.

Timbre

Qhov kev pom ntawm lub suab zoo kuj yog qhov zoo ntawm ib lub suab uas sib txawv ntawm lwm lub. Thaum cov twj paj nruag sib txawv ua si tib lub suab, lawv lub suab tuaj yeem sib txawv heev. Qhov no yog vim lawv cov nthwv dej tseem ceeb yog tib yam, tab sis cov khoom sib haum xeeb sib txawv heev. Yog li ntawd, lub suab tsis yog tsuas yog nyob ntawm nthwv dej tseem ceeb xwb, tab sis kuj muaj feem cuam tshuam nrog cov suab sib haum xeeb uas yog ib feem tseem ceeb ntawm nthwv dej tseem ceeb, uas ua rau txhua lub twj paj nruag thiab txhua tus neeg muaj lub suab sib txawv, tab sis qhov kev piav qhia tiag tiag yog qhov kev xav ntau dua thiab tej zaum yuav xav tias txawv txawv.

Dynamic

Qhov piv ntawm qhov muaj zog tshaj plaws rau qhov tsis muaj zog tshaj plaws hauv lub suab, qhia hauv dB. Piv txwv li, ib pawg suab muaj qhov sib txawv ntawm 90dB, uas txhais tau tias qhov tsis muaj zog tshaj plaws muaj zog tsawg dua 90dB dua li qhov nrov tshaj plaws. Qhov sib txawv ntawm lub zog yog qhov sib piv ntawm lub zog thiab tsis muaj dab tsi ua rau qib siab ntawm lub suab. Raws li tau hais ua ntej, qhov sib txawv ntawm ntau lub suab hauv xwm kuj hloov pauv heev. Lub teeb liab hais lus dav dav tsuas yog li 20-45dB, thiab qhov sib txawv ntawm qee cov suab paj nruag tuaj yeem ncav cuag 30-130dB lossis siab dua. Txawm li cas los xij, vim muaj qee qhov kev txwv, qhov sib txawv ntawm lub suab tsis tshua mus txog qhov sib txawv ntawm pawg suab. Lub suab nrov ntawm lub cuab yeej kaw suab txiav txim siab lub suab tsis muaj zog tshaj plaws uas tuaj yeem kaw tau, thaum lub peev xwm teeb liab siab tshaj plaws (qib kev cuam tshuam) ntawm lub kaw lus txwv lub suab muaj zog tshaj plaws. Feem ntau, qhov sib txawv ntawm lub teeb liab suab tau teeb tsa rau 100dB, yog li qhov sib txawv ntawm cov khoom siv suab tuaj yeem ncav cuag 100dB, uas zoo heev.

Tag nrho cov harmonics

Hais txog cov khoom sib xyaw ua ke ntawm cov teeb liab tso zis uas tshwm sim los ntawm cov khoom tsis sib xws dua li cov teeb liab nkag thaum lub suab teeb liab dhau los ntawm lub zog amplifier. Harmonic distortion yog tshwm sim los ntawm qhov tseeb tias lub kaw lus tsis yog linear tag nrho, thiab peb qhia nws ua feem pua ​​​​​​ntawm cov hauv paus ntsiab lus square ntawm cov khoom sib xyaw ua ke tshiab ntxiv rau tus nqi rms ntawm cov teeb liab thawj.
