Thaum lub electret condenser microphone tsis xav tau lub hwj chim los muab polarizing voltage, FET impedance txuam Circuit Court hauv lub microphone xav tau qee lub zog. Qhov no yuav muab los ntawm lub roj teeb me me uas tsis muaj hluav taws xob sab hauv lossis los ntawm cov khoom siv "phantom" sab nraud.

Koj ua li cas lub zog hluav taws xob microphone?

Vim tias lub microphone chaw nres nkoj ntawm lub computer muab kwv yees 2.3V ntawm lub zog, qhov no yuav ua rau lub zog hluav taws xob zoo kawg nkaus. Koj tuaj yeem txuas cov xov hlau jumper los ntawm 3.5mm audio plug cable thiab txuas rau sab zoo rau 2.2KΩ rub-up resistor thiab txuas rau sab tsis zoo rau hauv av davhlau ya nyob twg ntawm lub microphone.

Lub microphones xav tau lub hwj chim li cas?

Tsav kom yooj yim, condenser microphones muaj cov khoom siv hluav taws xob uas xav tau lub zog hluav taws xob sab nraud, thaum lub zog mics tsis muaj zog thiab yog li tsis xav tau lub zog phantom. Vim hais tias ntawm txoj kev condenser mics ua haujlwm, lawv cov khoom tso tawm yog qhov impedance siab heev, thiab yog li ntawd yuav tsum muaj lub zog hluav taws xob los txo qhov impedance.

Koj puas tuaj yeem siv lub microphone yam tsis muaj lub zog phantom?

Txawm hais tias tsis muaj txoj hauv kev siv lub mic condenser yam tsis muaj lub hwj chim phantom, koj tuaj yeem siv lub condenser mic yam tsis muaj suab interface, lossis sib xyaw ua ke, ncaj qha rau koj lub computer. Ua li ntawd koj xav tau koj xav tau XLR rau USB pre amp, xws li MXL Mic Mate Pro.

Electret microphone ua haujlwm li cas?

Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab hluav taws xob condenser yog uas lub diaphragm ua raws li ib lub phaj ntawm lub capacitor. Kev vibrations tsim kev hloov pauv ntawm qhov kev ncua deb ntawm lub diaphragm thiab lub phaj nraub qaum. … Qhov kev hloov pauv ntawm qhov hluav taws xob no tau nthuav dav los ntawm FET thiab lub suab teeb liab tshwm ntawm qhov tso zis, tom qab dc-blocking capacitor.
