Magnetoelectric (tsauri) - conductor (Magnetic coil), wanda ta cikinsa wutar lantarki ke gudana, ana sanya shi a cikin filin maganadisu. Haɗin kai da maganadisu da mai gudanarwa tare da halin yanzu yana haifar da motsi na mai gudanarwa wanda aka haɗa membrane. An haɗa coil ɗin da kyar zuwa diaphragm, kuma duk wannan an dakatar da shi ta hanyar da za a tabbatar da motsi axial na nada a cikin tazarar maganadisu ba tare da gogayya da maganadisu ba.
electromagnetic - Matsakaicin mitar sauti na halin yanzu yana haifar da musanyawan filin maganadisu. Yana magneticizes ferromagnetic core da ke da alaƙa da diaphragm, kuma jan hankali da tunkuɗe ainihin yana haifar da diaphragm don girgiza.
Electrostatic - wani electrified membrane sanya daga bakin ciki tsare - ciwon ajiya na karfe Layer a kan daya ko biyu sãsanninta ko kuma zama electret - yana shafar biyu perforated electrodes located a bangarorin biyu na tsare (a daya electrode, siginar lokaci yana juya 180 digiri tare da. girmamawa ga ɗayan), sakamakon abin da fim ɗin ya girgiza a lokaci tare da sigina.
magnetostrictive - filin maganadisu yana haifar da canji a cikin ma'auni na kayan ferromagnetic (maganin Magnetostrictive). Saboda yawan mitoci na abubuwa na ferromagnetic, ana amfani da irin wannan lasifikar don samar da duban dan tayi.
Piezoelectric - filin lantarki yana haifar da canji a cikin ma'auni na kayan piezoelectric; amfani da tweeters da ultrasonic na'urorin.
Ionic (marasa membrane) - nau'in lasifikar da ba ta da diaphragm wanda aikin diaphragm ke gudana ta hanyar baka na lantarki wanda ke samar da plasma.
Nau'in makirufo
Acid - allura da ke da alaƙa da diaphragm tana motsawa a cikin dilute acid. Contact (carbon) - haɓakar makirufo acid wanda a ciki aka maye gurbin acid da granules na carbon waɗanda ke canza juriya a ƙarƙashin matsin lamba da membrane ke yi akan granules. Ana amfani da irin waɗannan mafita a cikin wayoyi.
Piezoelectric – capacitor wanda ke canza siginar sauti zuwa siginar wutar lantarki.
Dynamic (magnetoelectric) - girgizar iska da aka ƙirƙira ta hanyar raƙuman sauti suna motsa diaphragm na bakin ciki mai sassauƙa da wani abin da ke da alaƙa da aka sanya shi a cikin filin maganadisu mai ƙarfi wanda maganadisu ke samarwa. A sakamakon haka, ƙarfin lantarki yana bayyana a kan maƙallan coil - ƙarfin lantarki, watau. girgizar maganadisu na nada, wanda aka sanya a tsakanin sanduna, yana haifar da wutar lantarki a cikinsa tare da mitar da ta dace da mitar girgizar igiyoyin sauti.
Makirifo mara waya ta zamani
Capacitive (electrostatic) - Wannan nau'in makirufo ya ƙunshi na'urorin lantarki guda biyu waɗanda ke da alaƙa da tushen wutar lantarki akai-akai. Daya daga cikinsu ba ya motsi, dayan kuma membrane ne wanda igiyoyin sauti suka shafa, yana sa shi girgiza.
Capacitive electret - bambance-bambancen makirufo na na'ura, wanda aka yi diaphragm ko tsayayyen rufin da aka yi da lantarki, watau. dielectric tare da m lantarki polarization.
Babban mitar capacitive - ya haɗa da madaidaicin oscillator da tsarin daidaitawa da tsarin demodulator. Canjin ƙarfin ƙarfi tsakanin na'urorin lantarki na makirufo yana daidaita girman siginar RF, daga wanda, bayan ƙaddamarwa, ana samun siginar ƙarancin mitar (MW), daidai da canje-canje a cikin matsa lamba na sauti akan diaphragm.
Laser - a cikin wannan zane, Laser katako yana nunawa daga farfajiyar girgiza kuma ya buga nau'in mai karɓa na hotuna. Darajar siginar ya dogara da wurin da katako yake. Saboda babban haɗin kai na katako na Laser, ana iya sanya membrane a nesa mai nisa daga mai watsa katako da mai karɓa.
Fiber na gani - hasken haske yana wucewa ta hanyar fiber na gani na farko, bayan tunani daga tsakiyar membrane, ya shiga farkon fiber na gani na biyu. Canje-canje a cikin diaphragm yana haifar da canje-canje a cikin ƙarfin haske, wanda aka canza zuwa siginar lantarki.
Makarufo don tsarin mara waya - Babban bambanci a cikin ƙirar makirufo mara igiyar waya shine kawai ta wata hanyar watsa siginar daban fiye da na tsarin waya. Maimakon kebul, ana shigar da na'ura mai watsawa a cikin akwati, ko wani nau'i daban-daban da aka haɗe zuwa kayan aiki ko mawaƙin ɗauke da shi, da kuma mai karɓar da ke kusa da na'ura mai haɗawa. Masu watsawa da aka fi amfani da su suna aiki a cikin tsarin daidaita mitar FM a cikin makada UHF (470-950 MHz) ko VHF (170-240 MHz). Dole ne a saita mai karɓa zuwa tashar guda ɗaya da makirufo.
