Tlhophiso ea liamplifier tse ling tsa molumo
Ka tlase u tla fumana litlhaloso tsa mefuta e fapaneng ea libui le li-microphone le karohano ea tsona ho latela molao-motheo oa ts'ebetso.
Karohano ea libuela-hōle ho latela molao-motheo oa ts'ebetso.
Magnetoelectric (matla) - conductor (magnetic coil), eo motlakase oa motlakase o phallang ka eona, e behoa ka matla a khoheli a makenete. Tšebelisano ea makenete le conductor ka hona joale e baka motsamao oa conductor oo lera le khomaretsoeng ho lona. Coil e hokahane ka thata le diaphragm, 'me sena sohle se emisoa ka tsela e netefatsang motsamao oa axial oa khoele ka lekhalo la makenete ntle le ho hohlana khahlanong le makenete.
motlakase - Phallo ea maqhubu a acoustic e etsa hore ho be le matla a khoheli a fapaneng. E hokela ferromagnetic core e hokahantsoeng le diaphragm, 'me ho hoheloa le ho nyenyefatsa ha mantlha ho etsa hore diaphragm e thothomele.
Motlakase - lesela la motlakase le entsoeng ka foil e tšesaane - le nang le lesela la tšepe le behiloeng ka lehlakoreng le le leng kapa ka bobeli kapa ho ba motlakase - le angoa ke li-electret tse peli tse nang le li-perforated tse ka mahlakoreng a mabeli a foil (ka elektrode e le 'ngoe, mohato oa pontšo o fetoloa likhato tse 180 tlhompho ho tse ling), ka lebaka leo Filimi e sisinyeha ka nako le pontšo.
magnetostrictive - matla a khoheli a baka phetoho ho boholo ba thepa ea ferromagnetic (magnetostrictive phenomenon). Ka lebaka la maqhubu a phahameng a tlhaho a likarolo tsa ferromagnetic, mofuta ona oa sebuela-hōle o sebelisoa ho hlahisa ultrasound.
Piezoelectric - sebaka sa motlakase se baka phetoho ho litekanyo tsa thepa ea piezoelectric; e sebelisoa ho li-tweeters le lisebelisoa tsa ultrasonic.
Ionic (e se nang membrane) - mofuta oa sebui se se nang diaphragm moo mosebetsi oa diaphragm o etsoang ke arc ea motlakase e hlahisang plasma.
Mefuta ea li-microphone
Asiti - nale e amanang le diaphragm e tsamaea ka acid e hlapollang. Kopana (khabone) - nts'etsopele ea maekerofounu ea acid eo acid e nkeloang sebaka ke li-granules tsa carbon tse fetolang ho hanyetsa ha tsona tlas'a khatello e hlahisoang ke lera holim'a granules. Litharollo tse joalo li sebelisoa hangata lithelefonong.
Piezoelectric - capacitor e fetolang lets'oao la acoustic hore e be lets'oao la motlakase.
Matla (magnetoelectric) - ho sisinyeha ha moea ho entsoeng ke maqhubu a molumo ho tsamaisa diaphragm e tšesaane e tenyetsehang le khoele e amanang le eona e behiloeng sebakeng se matla sa makenete se hlahisoang ke makenete. Ka lebaka leo, motlakase o hlaha ho li-terminals tsa coil - matla a electrodynamic, i.e. ho thothomela ha makenete ea coil, e behiloeng pakeng tsa lipalo, e etsa hore ho be le motlakase ho eona ka maqhubu a lumellanang le maqhubu a ho sisinyeha ha maqhubu a molumo.
Microphone ea sejoale-joale e se nang mohala
Capacitive (electrostatic) - Mofuta ona oa microphone o na le li-electrode tse peli tse hokahaneng le mohloli oa motlakase o sa khaotseng. E 'ngoe ea tsona ha e sisinyehe, 'me e 'ngoe ke lera le angoang ke maqhubu a molumo, e etsang hore e thothomele.
Capacitive electret - phapang ea microphone ea condenser, eo ho eona diaphragm kapa lesela le tsitsitseng le entsoeng ka electret, i.e. dielectric ka polarization ea kamehla ea motlakase.
High frequency capacitive - e kenyelletsa oscillator ea maqhubu a phahameng le mochini oa symmetrical modulator le demodulator system. Phetoho ea bokhoni pakeng tsa li-electrode tsa microphone e fetola boholo ba matšoao a RF, moo, ka mor'a ho fokotseha, ho fumanoa lets'oao la "low-frequency" (MW), le lumellanang le liphetoho tsa khatello ea acoustic ho diaphragm.
Laser - moralong ona, beam ea laser e bonahala ho tsoa sebakeng se thothomelang mme e otla karolo ea lifoto ea moamoheli. Boleng ba pontšo bo itšetlehile ka sebaka sa beam. Ka lebaka la momahano o phahameng oa lebone la laser, lesela le ka beoa sebaka se selelele ho tloha ho transmitter le moamoheli.
Optical fiber - khanya ea leseli e fetang ka har'a fiber ea pele ea optical, ka mor'a ho bonahatsa ho tloha bohareng ba lera, e kena qalong ea fiber ea bobeli ea optical. Ho feto-fetoha ha diaphragm ho baka liphetoho ho matla a khanya, ebe joale a fetoloa letšoao la motlakase.
Li-microphone bakeng sa litsamaiso tse se nang mohala - phapang e kholo ea moralo oa microphone e se nang mohala ke feela ka tsela e fapaneng ea ho fetisa matšoao ho feta tsamaiso ea mohala. Sebakeng sa thapo, transmitter e kentsoe nyeoeng, kapa mojule o arohaneng o kentsoeng sesebelisoa kapa o tsamaisoang ke sebini, le moamoheli o haufi le mochini o kopanyang. Li-transmitters tse sebelisoang haholo li sebetsa ho sistimi ea frequency modulation ea FM ho lihlopha tsa UHF (470-950 MHz) kapa VHF (170-240 MHz). Moamoheli o tlameha ho hlophisoa ho kanale e tšoanang le maekrofono.
