Kev paub txog ntau yam kev ua yeeb yam ntawm cov neeg hais lus nrov hauv lub mloog pob ntseg
Impedance: The impedance of the earphone is the abbreviation of its AC impedance. Impedance refers to the resistance to alternating current in a circuit with resistance, inductance and capacitance. The unit is ohm (Ω). Generally speaking, the lower the impedance, the easier the earphones are to sound and drive. The size of the headphone impedance is also closely related to the sound quality of the headphone. The impedance changes with the frequency. The impedance of the headphone is larger at low frequencies and smaller at high frequencies, so for most headphones, increasing the impedance will make the sound become more feeble.
rhiab heev: Lub rhiab heev ntawm lub pob ntseg yog hais txog lub suab siab uas lub pob ntseg tuaj yeem tawm thaum lub zog ntawm 1 mW nkag mus rau lub pob ntseg (lub suab siab yog decibel, lub suab siab dua, qhov ntim siab dua), Yog li qhov siab dua qhov rhiab heev, qhov qis dua qhov impedance. , qhov yooj yim lub mloog pob ntseg yog suab thiab tsav. Feem ntau, lub mloog pob ntseg yog siv rau kev siv txhua hnub, thiab qhov rhiab heev yog nyiam nyob ib puag ncig 100dB / mW lossis siab dua.
Cov lus teb ntau zaus: cov lus teb ntau zaus, tseem hu ua cov yam ntxwv zaus, tib neeg lub suab nrov yog 20Hz-20KHz, qhov qis dua cov lus teb, qhov zoo dua cov ntses bass thaj tsam, thiab cov lus teb ntau dua, qhov siab dua qhov treble. Tau kawg, nws kuj nyob ntawm qhov ua yuam kev ntau. Qhov me dua qhov kev ua yuam kev ntau, lub suab meej ntawm txhua zaus tuaj yeem ua tau.
Chav tsev loj: Feem ntau hais lus, qhov loj thiab txoj kab uas hla ntawm chav tsev yog txuas nrog lub suab zoo. Rau qee qhov, qhov loj dua chav tsev, qhov dav dua qhov zaus ntawm lub mloog pob ntseg, tab sis qhov no tsis yog qhov tseeb. Qhov no kuj suav nrog lub zog ntawm lub mloog pob ntseg, zaus teb, rhiab heev, impedance txuam, suab qhov zoo, thiab lwm yam.
