Nthuav

Hais txog seb tus neeg hais lus puas txhawb nqa ntau lub tswv yim ib txhij, seb puas muaj qhov tso zis tawm rau cov neeg hais lus ib puag ncig passive, seb nws puas muaj USB input muaj nuj nqi, thiab lwm yam. Tus naj npawb ntawm cov subwoofer uas tuaj yeem txuas nrog cov neeg hais lus ib puag ncig sab nraud kuj yog ib qho ntawm cov qauv ntsuas kev nthuav dav. Cov kev sib txuas ntawm cov neeg hais lus multimedia feem ntau suav nrog analog interfaces thiab USB interfaces. Lwm tus, xws li optical fiber interfaces thiab cov tshiab digital interfaces, tsis yog ntau heev.

Suab nyhuv

Cov cuab yeej siv ntau dua 3D suab cuam tshuam thev naus laus zis suav nrog SRS, APX, Spatializer 3D, Q-SOUND, Virtaul Dolby thiab Ymersion. Txawm hais tias lawv muaj cov kev siv sib txawv, lawv txhua tus tuaj yeem ua rau tib neeg hnov ​​​​qhov pom tseeb ntawm peb-dimensional suab teebmeem. Thawj peb yog ntau dua. Qhov lawv siv yog Extended Stereo txoj kev xav, uas yog ntxiv rau cov txheej txheem lub suab teeb liab los ntawm lub voj voog, kom cov neeg mloog xav tias lub suab duab coj mus rau sab nraud ntawm ob tus neeg hais lus, txhawm rau nthuav cov duab suab thiab ua rau tib neeg muaj qhov chaw nkag siab thiab peb-dimensionality, uas ua rau lub suab nrov nrov. Tsis tas li ntawd, muaj ob lub suab txhim kho thev naus laus zis: active electromechanical servo technology (tseem ceeb yog siv Helmholtz resonance hauv paus ntsiab lus), BBE high-txhais toj siab lub suab reproduction system technology thiab "phase fax" technology, uas kuj muaj qee yam cuam tshuam rau kev txhim kho suab zoo. Rau cov neeg hais lus multimedia, SRS thiab BBE thev naus laus zis yooj yim dua rau kev siv thiab muaj cov txiaj ntsig zoo, uas tuaj yeem txhim kho kev ua tau zoo ntawm cov neeg hais lus.

Tone

Hais txog lub teeb liab nrog ib qho tshwj xeeb thiab feem ntau ruaj khov wavelength (pitch), hais lus sib tham, lub suab nrov. Nws tsuas yog nyob ntawm lub wavelength. Rau lub suab nrog lub suab luv luv, tib neeg pob ntseg teb nrog lub suab siab, thaum lub suab nrog lub suab ntev, tib neeg pob ntseg teb nrog lub suab qis. Kev hloov hauv suab nrog wavelength yog qhov tseem ceeb logarithmic. Cov twj paj nruag sib txawv ua si tib daim ntawv, txawm hais tias lub suab sib txawv, tab sis lawv lub suab yog tib yam, uas yog, qhov tseem ceeb ntawm lub suab yog tib yam.

Timbre

Kev xaav ntawm lub suab zoo kuj yog tus yam ntxwv zoo ntawm ib lub suab uas txawv ntawm lwm tus. Thaum cov twj paj nruag sib txawv ua si tib lub suab, lawv cov ntoo tuaj yeem sib txawv heev. Qhov no yog vim tias lawv cov nthwv dej tseem ceeb yog tib yam, tab sis cov khoom sib haum xeeb sib txawv heev. Yog li ntawd, lub timbre tsis tsuas yog nyob ntawm lub hauv paus yoj, tab sis kuj yog ze ze rau cov harmonics uas yog ib feem tseem ceeb ntawm lub hauv paus yoj, uas ua rau txhua lub suab paj nruag thiab txhua tus neeg muaj ib tug sib txawv timbre, tab sis qhov tseeb piav qhia yog ntau subjective thiab tej zaum yuav xav tsis thoob.

Dynamic

Qhov piv ntawm qhov muaj zog tshaj plaws rau qhov tsis muaj zog hauv lub suab, qhia hauv dB. Piv txwv li, ib pab pawg muaj qhov sib txawv ntawm 90dB, uas txhais tau hais tias qhov tsis muaj zog tshaj plaws muaj 90dB tsawg zog tshaj qhov nrov tshaj plaws. Dynamic ntau yog qhov piv ntawm lub hwj chim thiab tsis muaj dab tsi ua nrog rau theem meej ntawm lub suab. Raws li tau hais ua ntej, qhov sib txawv ntawm ntau lub suab hauv qhov xwm txheej kuj sib txawv heev. Lub teeb liab hais lus dav dav tsuas yog hais txog 20-45dB, thiab qhov sib txawv ntawm qee qhov symphonies tuaj yeem ncav cuag 30-130dB lossis siab dua. Txawm li cas los xij, vim qee qhov kev txwv, dynamic ntau ntawm lub suab kaw lus tsis tshua muaj mus txog qhov dynamic ntau ntawm cov qhab. Lub suab nrov ntawm cov cuab yeej kaw tau txiav txim siab lub suab tsis muaj zog uas tuaj yeem kaw tau, thaum lub teeb liab siab tshaj plaws (qib distortion) ntawm lub kaw lus txwv lub suab nrov tshaj plaws. Feem ntau, dynamic ntau yam ntawm lub suab teeb liab yog teem rau 100dB, yog li qhov dynamic ntau ntawm cov khoom siv suab tuaj yeem ncav cuag 100dB, uas yog qhov zoo heev.

Tag nrho cov harmonics

Hais txog cov khoom sib haum xeeb ntxiv ntawm cov teeb liab tso zis tshwm sim los ntawm cov khoom tsis sib xws tshaj li cov teeb liab tawm tswv yim thaum lub suab teeb liab dhau los ntawm lub hwj chim amplifier. Harmonic distortion yog tshwm sim los ntawm qhov tseeb hais tias lub system tsis yog tag nrho linear, thiab peb qhia nws raws li ib feem pua ​​​​ntawm cov hauv paus ntsiab lus square ntawm lub tshiab ntxiv tag nrho harmonic tivthaiv rau rms tus nqi ntawm cov thawj teeb liab.
