Lub electret microphone yog ib hom electrostatic capacitor-based microphone, uas tshem tawm qhov xav tau rau lub zog polarizing los ntawm kev siv cov khoom siv tas mus li. Ib qho hluav taws xob yog cov khoom siv hluav taws xob ruaj khov nrog cov khoom siv hluav taws xob mus tas li static hluav taws xob dipole lub sijhawm.
Electret condenser microphone ua haujlwm li cas?
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab hluav taws xob condenser yog tias lub diaphragm ua raws li ib lub phaj ntawm lub capacitor. Vibrations tsim kev hloov nyob rau hauv qhov kev ncua deb ntawm lub diaphragm thiab lub nraub qaum phaj. … 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.
Qhov txawv ntawm electret thiab condenser microphone yog dab tsi?
Qhov txawv ntawm ob yog qhov DC-biased condenser xav tau lub zog hluav taws xob sab nraud los muab qhov hluav taws xob polarizingthaum lub tshuab hluav taws xob siv lub tshuab ua ntej polarized lossis rov qab phaj. Feem ntau condenser microphones siv niaj hnub no yog electret.
Electret microphones puas zoo?
A zoo rov qab-electret mic tuaj yeem ua tau txhua qhov me ntsisnrog rau cov qauv tsim cov khoom siv hluav taws xob, thiab qee qhov zoo dua me ntsis, txawm hais tias tus nqi hluav taws xob kaw hauv cov khoom siv hluav taws xob. tuaj yeem xau tawm qeeb heev nyob rau lub sijhawm ntawm ntau xyoo caum, ua rau txo qis me ntsis hauv qhov rhiab heev.
Electret microphones puas phem?
Cov nrogKev paub ntev ntev nco ntsoov thaum electret microphones tau pheej yig heev thiab lawv cov kev ua haujlwm siab thiab kev nkag siab tau raug cuam tshuam. Lawv tau lub koob npe phem hauv 70s thiab 80s. Ntau tus qauv hluav taws xob thaum ntxov tau tuag tom qab ob peb xyoos, feem ntau vim lawv poob lawv cov nqi hluav taws xob.
