Lub mloog pob ntseg yog ob chav hloov dua siab tshiab uas tau txais cov teeb liab hluav taws xob los ntawm cov neeg siv xov xwm lossis cov neeg txais xov xwm thiab hloov lawv mus rau hauv cov suab tsis hnov lus siv cov neeg hais lus ze ntawm pob ntseg. Lub mloog pob ntseg feem ntau yog detachable los ntawm media player thiab txuas nrog siv lub ntsaws. Qhov zoo dua yog tias koj tuaj yeem mloog lub suab ib leeg tsis cuam tshuam rau lwm tus; Nws kuj tseem tuaj yeem cais cov suab nrov ntawm ib puag ncig ib puag ncig, uas yog qhov muaj txiaj ntsig zoo rau cov neeg siv hauv qhov chaw nrov nrov xws li kaw cov studios, DJs, mus ncig, thiab kev ua kis las.
Lub mloog pob ntseg tau tsim los siv rau hauv xov tooj thiab xov tooj cua, tab sis nrog kev nthuav dav ntawm cov khoom siv hluav taws xob portable, lawv tau dhau los siv ntau hauv xov tooj ntawm tes, taug kev, thiab xov tooj cua. Portable video games thiab digital audio players. Los ntawm txoj kev xav ntawm txoj kev loj hlob ntawm tag nrho cov suab kev lag luam, wireless headphones tseem suav hais tias yog ib qho tshiab, nrog rau lub sijhawm luv luv. Lawv tseem nyob rau hauv ib qho kev nce siab, thiab cov neeg siv khoom xav tau nce ntxiv. Cov kev cia siab ntawm cov neeg siv rau lub mloog pob ntseg wireless tseem nce ntxiv, uas yog qhov kev sib tw tshiab rau kev lag luam.
Yuav ua li cas paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo ntawm lub pob ntseg:
1. Pob ntseg rhiab heev:
Nyob rau hauv tib lub suab nrov, qhov siab dua ntawm lub mloog pob ntseg, qhov me me ntawm lub zog hluav taws xob xav tau rau lub suab nrov. Qhov yooj yim dua nws yog tsav lub mloog pob ntseg.
2. Kev teb ntau zaus:
Qhov dav ntawm cov zaus band uas lub mloog pob ntseg tuaj yeem tawm. Raws li International Electrotechnical Commission's IEC581-10 tus qauv, cov lus teb zaus ntawm lub mloog pob ntseg siab tsis tuaj yeem tsawg dua 50Hz txog 12500Hz. Cov lus teb zaus dav ntawm lub mloog pob ntseg zoo tuaj yeem ncav cuag 5Hz txog 40000Hz, thaum lub mloog pob ntseg ntawm tib neeg tsuas yog nyob ib puag ncig 20Hz txog 2000Hz. Cov neeg siv yuav tsum nco ntsoov tias qhov ntau zaus teb dav ntawm cov hom sib txawv ntawm lub mloog pob ntseg yuav muaj cov qauv sib txawv thaum yuav khoom.
3. Lub mloog pob ntseg impedance:
Cov ntawv luv rau kev sib txuas lus impedance ntawm lub mloog pob ntseg yog tias lub mloog pob ntseg nrog cov impedances sib txawv yog siv rau ntau lub sijhawm, ntawm desktop computers. Lub mloog pob ntseg siab impedance feem ntau yog siv, thiab qee lub mloog pob ntseg tuaj yeem muaj qhov impedance ntawm tshaj 200 ohms, uas yog kom phim lub mloog pob ntseg ntawm cov tshuab kev tshaj lij. Rau ntau yam khoom siv hluav taws xob portable, lub mloog pob ntseg qis impedance feem ntau yog siv, uas yooj yim rau kev tsav tsheb.
4. Harmonic distortion:
Ib hom waveform distortion, qhia nyob rau hauv lub mloog pob ntseg ntsuas, qhov twg me dua qhov distortion, lub suab zoo dua.
