Six Pitfalls ntawm Headphone Shopping

Pitfall ib: zaus teb ntau
Cov lus teb ntau zaus, lub npe tag nrho ntawm cov lus teb ntau zaus, tseem hu ua cov yam ntxwv zaus. Tib neeg hnov ​​​​lus yog qhov yuam kev vibration (resonance) los ntawm kev vibration ntawm lub pob ntseg rau lub suab. Lub theoretical siab tshaj plaws tus nqi ntawm kev hnov ​​lus yog 20Hz ~ 20000Hz, siab tshaj qhov no yog hu ua ultrasound, thiab qis dua yog hu ua infrasound, uas yog ntau raws li qhov kev xav ntawm kov es tsis hnov ​​lus.
Tam sim no, ntau lub mloog pob ntseg siab kawg muaj qhov dav qhov dav ntawm 20Hz rau 20 00Hz, thiab qee qhov txawm tias muaj qhov dav dav nominal ntawm 5Hz rau 50 00Hz. Nws yog tsim nyog sau cia tias qhov no yog vim hais tias tus qauv txwv zaus teb dav tshwm sim los ntawm qhov sib txawv, xws li cov chaw tsim khoom yog cov zis amplitude txo los ntawm 1/2 raws li tus qauv ntsuas zaus teb dav, uas yog hais rau -3dB(decibel tus naj npawb) raws li tus qauv, tab sis qee cov khoom yog rau -lOdB (decibel tus lej) raws li tus qauv ntsuas, uas yog qis dua li tus nqi ib txwm muaj ntawm 1 qhov rooj 6 hauv qab tus qauv los ntsuas, Yog li ntawd, keeb kwm ntawm keeb kwm tsuas yog ib qho teeb meem ntawm sij hawm.
Kev teb ntau zaus yog qhov tseem ceeb, tab sis tsis tseem ceeb npaum li koj xav. Thaum koj yuav lub mloog pob ntseg, tsis tas yuav tsum tau them nyiaj ntau dhau rau qhov ntsuas no, nws tuaj yeem piav qhia qee yam teeb meem (cov neeg tsim khoom cia siab rau qhov no los txhim kho kev lag luam ntawm lub mloog pob ntseg, cov khoom qib siab zoo dua li qib qis yog ib txwm muaj), tab sis tsis tuaj yeem piav qhia tag nrho cov teeb meem, txhawm rau txiav txim siab qhov zoo thiab qhov tsis zoo ntawm lub mloog pob ntseg thiab raws li kev xaiv ntawm cov khoom lag luam tsis xav tau.
Npuag ob: impedance
Impedance yog luv rau lub mloog pob ntseg AC impedance. Txawv high-impedance earphones yog siv nyob rau hauv ntau zaus. Ntawm cov cuab yeej tshaj lij xws li cov chaw sib xyaw suab, cov pob ntseg siab impedance feem ntau yog siv. Feem ntau, lub mloog pob ntseg impedance yog ntau dua 2000, uas yog tshwm sim los ntawm kev sib txuam nrog lub mloog pob ntseg ntawm cov khoom siv tshaj lij. Rau cov neeg taug kev nqa tau yooj yim, xws li CDS, MDS lossis MP3s, lub mloog pob ntseg qis impedance feem ntau yog siv.
Lub mloog pob ntseg impedance tsis tau pib tsis muaj dab tsi cuam tshuam nrog qhov zoo ntawm lub mloog pob ntseg. Txawm hais tias qhov parameter no tseem ceeb, nws yuav tsum tau saib nrog koj lub cuab yeej siv los siv. Yog tias koj siv cov pob ntseg transistor lossis MP3 players, xov tooj ntawm tes, thiab lwm yam, lub mloog pob ntseg tsis tshua muaj zog yuav tsum zoo dua hauv kev xav (tseem tsis yog qhov tseeb, tseem nyob ntawm qhov xwm txheej tiag tiag, yog li mloog qhov tseeb). Yog tias koj muaj lub raj ntawm tes, lub mloog pob ntseg siab tuaj yeem tswj tau zoo dua.
Trap nab npawb peb: Sensitivity
Raws li ib qho tseem ceeb raws li impedance yog rhiab heev, tus sau feem ntau siv nws thiab impedance raws li kev soj ntsuam parameter los sib piv cov collocation ntawm headphones thiab earphones.
Qee tus neeg muaj txiaj ntsig yuav hais tias "lub mloog pob ntseg ntau dua, nws yuav yooj yim dua rau kev tsav tsheb". tiag tiag? Kuv ntshai nws tsis tas yuav yog rooj plaub uas lub mloog pob ntseg nyuaj ua kom zoo, rau tib yam li cov neeg hais lus. Piv txwv tias lub impedance ntawm chav tsev yog tsau, ces txhua yam yog yooj yim txaus kom suab nrov txaus kom muaj peev xwm thawb. Tab sis lub impedance ntawm chav tsev ntawm ntau zaus tsis tas!
Txawm hais tias rhiab heev kuj yog ib qho tseem ceeb siv Performance index, tab sis lub suab khoom pib muaj tsawg, nws yog ib qho nyuaj rau ua tau zoo. Tam sim no, txoj kev ua tau ntau dua, ib qho yog los ntawm ntau qhov kev ntsuas kev xav; Lwm txoj kev yog tseem mloog. Tom qab tag nrho, pob ntseg tsis dag rau koj.
Npuag tooj plaub: Nthuav hom
Kev txiav txim siab qhov zoo ntawm cov khoom los ntawm nws cov tsos yog ua tau nyob rau hauv qee kis, tab sis nws yuav tsum muaj peev xwm txiav txim siab dua. Lub mloog pob ntseg zoo dua qub, kev ua haujlwm zoo, xav tias zoo heev, yuav tsum tsis txhob siv cov yas tsis zoo uas tsis zoo. Tsis tas li ntawd, lub mloog pob ntseg lead hlau txoj kab uas hla yog tuab, mos thiab tsis tawv. Cov kev cai ntsaws ntawm tus qauv zoo yam tsis muaj burr, du thiab uniform txheej.
Tsis tas li ntawd, nws raug nquahu kom koj mus rau kev lag luam niaj hnub mus yuav, yuav cov khoom lag luam tom qab kev paub dhau los, vim tias lub mloog pob ntseg loj tsis tas yuav tsum zoo tag nrho, saib qhov kev ntsuam xyuas ntawm lub mloog pob ntseg tsab xov xwm, nyeem cov ntawv ntsuam xyuas kom pom cov shortcomings, raws li zoo raws li lub xeem ib puag ncig, es blindly saib qhov zoo, tag nrho npaj thiab ces yuav yog ib lub tswv yim zoo.
