Dab tsi yog lub mloog pob ntseg amplifier rau

Raws li lub npe qhia, lub mloog pob ntseg amplifier yog ib qho cuab yeej uas yuav siv los ua kom nrov suab nrov ntawm qhov tso zis, piv txwv li ib qho uas peb tso tawm, piv txwv li, los ntawm hi-fi system lossis xov tooj, thiab muab tso rau hauv peb lub mloog pob ntseg. . Ntawm chav kawm, raws li tus qauv, txhua yam khoom siv uas muaj lub mloog pob ntseg tso tawm muaj xws li amplifier built-in, tab sis nws yuav tshwm sim tias lub teeb liab tsis muaj zog txaus kom txaus siab rau peb. Qhov no feem ntau yog cov ntaub ntawv me me xws li laptops, xov tooj ntawm tes lossis mp3 players, qhov chaw tso zis hluav taws xob yog txwv. Los ntawm kev sib txuas xws li amplifier, peb lub mloog pob ntseg yuav tau txais ib feem ntxiv ntawm lub zog thiab yuav siv tau tag nrho cov peev xwm ntawm lawv cov transducers.

Yuav ua li cas los xyuas seb lub mloog pob ntseg xav tau lub amplifier

Hmoov tsis zoo, tsis yog txhua lub mloog pob ntseg yuav tuaj yeem siv tag nrho lub mloog pob ntseg ntxiv yam tsis tau poob lub suab zoo. Txawm hais tias peb lub mloog pob ntseg tuaj yeem siv lub zog ntxiv tuaj yeem kuaj xyuas los ntawm kev txheeb xyuas qhov tsis qhia hauv Ohms thiab SPL parameter. Piv txwv li, yog hais tias lub mloog pob ntseg yog tus cwj pwm los ntawm kev ua haujlwm siab hais tawm hauv ohms thiab tib lub sijhawm qis SPL, ces lub mloog pob ntseg yog qhov tsim nyog tshaj plaws rau lub teeb liab los ua kom nrov ua tsaug rau ib qho ntxiv amplifier. Yog hais tias, ntawm qhov tod tes, ob qho tib si cov kev txwv no nyob rau theem qis, lub teeb liab yuav nyuaj rau kev nthuav dav.

Hom ntawm lub mloog pob ntseg amplifiers

Lub mloog pob ntseg amplifiers tuaj yeem muab faib vim lawv cov kev tsim kho thiab cov cuab yeej siv rau qhov no. Qhov nrov tshaj plaws yog transistor amplifiers, uas yog raws li transistors. Xws li lub amplifier yog tus nqi pheej yig thiab muab qhov nruab nrab feem ntau, kev ua haujlwm zoo, suab zoo. Peb kuj tseem tuaj yeem yuav lub tshuab hluav taws xob uas siv cov cuab yeej siv uas vam meej hauv 60s. Tube amplifiers muaj lawv cov kiv cua rau hnub no vim lawv tsim ib qho chaw tshwj xeeb. Cov thev naus laus zis no kim dua los tsim, yog li tus nqi ntawm cov amplifiers tuaj yeem yog ob peb zaug kim dua li cov transistor. Thiab peb tuaj yeem yuav lub amplifier uas sib txuas cov thev naus laus zis tshiab nrog rau xyoo dhau los.
