Tus neeg hais lus puas tuaj yeem ua haujlwm yam tsis muaj lub rooj tsavxwm amplifier?
Feem ntau,cov neeg hais lus tsis tuaj yeem ua haujlwm (piv txwv li, tsim lub suab nrov) yam tsis muaj lub rooj tsavxwm amplifier-thiab qhov kev zam tsuas yog cuam tshuam nrog cov xwm txheej uas "kev ua kom muaj zog" twb tau muab tso rau hauv lwm lub cuab yeej, tsis yog tus hais lus ua haujlwm ntawm nws tus kheej yam tsis muaj kev nthuav dav. Hauv qab no yog cov ncauj lus kom ntxaws:
1. Vim li cas cov neeg hais lus feem ntau tsis tuaj yeem ua haujlwm yam tsis muaj Amplifier Board
Raws li tau piav ua ntej, cov neeg hais lus cia siab rauelectromagnetic quab yuam tsav lawv diaphragms thiab vibrate cua(tsim suab). Txawm li cas los xij:
Cov khoom siv suab (xws li smartphones, TVs, computers, turntables) tsuas yog tso tawmtsis muaj zog hluav taws xob teeb liab(feem ntau yog ob peb millivolts rau kaum millivolts, nrog microamp-theem tam sim no). Cov teeb liab no muaj cov ntaub ntawv suab tab sis tsis muaj "lub zog" txav tus neeg hais lus lub suab coil thiab diaphragm.
Ib tus neeg hais lus tus tsav tsheb (cov hlau nplaum + lub suab coil + diaphragm) yuav tsum tauampere- theem tam sim nolos tsim kom muaj zog electromagnetic txaus rau audible vibration. Yog tsis muaj kev nthuav dav, qhov tsis muaj zog qhov teeb liab tsuas tuaj yeem tsim cov diaphragm txav inaudibly faint (lossis tsis muaj kev txav ntawm txhua qhov)-koj yuav hnov tsis muaj lub ntsiab lus.
2. Tsuas yog "Tshwj Xeeb": Amplification yog koom ua ke lwm qhov
Qee qhov xwm txheej zoo li cuam tshuam nrog "tus hais lus ua haujlwm yam tsis muaj lub rooj sib tham sib cais," tab sis qhov no tsuas yog kev nkag siab tsis zoo-lub amplification muaj nuj nqi tsuas yog ua rau hauv lwm lub cuab yeej, tsis tuaj. Cov piv txwv uas muaj xws li:
Ua-hauv- amplifier hais lus (tus hais lus nquag)Cov khoom siv xws li Bluetooth hais lus, desktop computer tham, lossisntse hais lusfeem ntau sau tias "active"-lawv muaj lub rooj tsavxwm me me (lossis nti) muab zais rau hauv lawv lub casing. Thaum koj txuas lawv rau hauv xov tooj lossis khoos phis tawj, lub amp sab hauv ua ntej ua kom lub zog tsis muaj zog, tom qab ntawd xa lub zog txhawb nqa mus rau tus hais lus tus tsav tsheb. Koj tsis pom "sib cais" amp board, tab sis amplification tseem tshwm sim.
Cov ntaub ntawv suab nrog ua - nyob rau hauv lub zog amplificationOb peb yam khoom siv (piv txwv li, qee lub xov tooj cua vintage, cov kab xev qub, lossis cov suab paj nruag tshwj xeeb portable) muaj cov khoom siv hluav taws xob me me ua rau hauv lawv qhov chaw tso zis. Piv txwv li, lub xov tooj cua retro tej zaum yuav muaj ib qho ua tau - nyob rau hauv amp uas ncaj qha tsav nws cov neeg hais lus sab hauv- tsis xav tau amp board sab nraud, tab sis lub xov tooj cua nws tus kheej muaj cov khoom ua kom nrov.
Headphones (ib "tus hais lus me me"exception)Lub mloog pob ntseg yog qhov tseem ceeb me me hais lus, tab sis lawv muaj lub teeb yuag diaphragms thiab lub suab coils uas xav tau lub zog tsawg dua los tsav. Lub teeb liab tsis muaj zog los ntawm lub xov tooj lub mloog pob ntseg tsuas tuaj yeem tsuas yog muab tam sim no txaus rau lub mloog pob ntseg los tsim lub suab nrov (txawm hais tias qhov no tseem yog "tseem ceeb tshaj plaws"-ntau lub xov tooj suab chips suav nrog theem amp me me los txhawb lub teeb liab rau lub mloog pob ntseg- qib siab nyiam). Standard full-loj hais lus (xws li, phau ntawv txee lossis cov qauv hauv pem teb) ua tsis tau li no, vim lawv cov tsav tsheb loj xav tau ntau lub zog.
3. Qhov tseem ceeb Takeaway
Tsis muaj qhov "tseem ceeb tshwj xeeb" qhov twg tus neeg hais lus ua suab nrovtsis muaj amplification. Txoj cai tuav:
Yog tias koj siv atus hais lus passive(hom feem ntau, piv txwv li, standalone phau ntawv txee / floorstanding hais lus,tsheb hais lus), kojyuav tsumua ke nrog lub rooj tsavxwm amplifier (lossis lwm lub suab nrov) kom tau suab.
Yog hais tias tus hais lus zoo li ua haujlwm "tsis muaj amp," nws yog ib qhotus hais lus nquag(nrog rau qhov zais amp sab hauv) lossis txuas nrog lub hauv paus uas muaj qhov ua tau - hauv amp.
Hauv luv luv: Amplification tsis yog "yeem ntxiv" rau cov neeg hais lus- nws yog ib qho tseem ceeb uas yuav tsum tau hloov cov hluav taws xob tsis muaj zog rau hauv lub suab nrov.
