1. Isithethi semagnethi sine-electromagnet ene-iron core eshukumayo phakathi kwezibonda ezimbini zemagnethi esisigxina. Xa kungekho current kwi-coil ye-electromagnet, i-iron core eshukumayo itsalwa kukutsalwa kwe-phase-level kwezibonda ezimbini zemagnethi esisigxina kwaye ihlala imile embindini; Xa umbane uhamba kwi-coil, i-iron core eshukumayo iba yi-magnet kwaye ibe yi-bar magnet. Ngokutshintsha kwendlela yangoku, i-polarity ye-bar magnet nayo iyatshintsha ngokufanayo, ukuze i-iron core eshukumayo ijikeleze i-fulcrum, kwaye ukungcangcazela kwe-iron core eshukumayo kudluliselwa ukusuka kwi-cantilever ukuya kwi-diaphragm (ikhowuni yephepha) ukuze kutyhalelwe umoya ukuba ungcangcazele ngobushushu.

2. Isithethi se-Electrostatic Sisithethi esisebenzisa amandla e-electrostatic ongezwe kwipleyiti ye-capacitor. Ngokwesakhiwo sayo, ikwabizwa ngokuba yi-capacitor speaker kuba ii-electrode ezilungileyo nezingalunganga zichasene. Izinto ezimbini eziqinileyo neziqinileyo zisetyenziswa njengeepleyiti ezizinzileyo, ezinokudlulisa isandi kwiipleyiti, kwaye ipleyiti ephakathi yenziwe ngezinto ezibhityileyo nezikhaphukhaphu njengee-diaphragms (ezifana nee-diaphragms ze-aluminium). Lungisa kwaye uqinise ujikeleze i-diaphragm kwaye ugcine umgama omde ukusuka kwi-fixed pole. Nokuba kwi-diaphragm enkulu, ayizukungqubana ne-fixed pole.
3. Izithethi zePiezoelectric Isithethi esisebenzisa isiphumo sePiezoelectric esichaseneyo sezixhobo zePiezoelectric sibizwa ngokuba sisithethi sePiezoelectric. Imeko yokuba iDielectric (efana neQuartz, iPotassium Sodium Tartrate kunye nezinye iikristale) i-polarized phantsi kwesenzo soxinzelelo, nto leyo ebangela umahluko onokubakho phakathi kweziphelo ezibini zomphezulu, obizwa ngokuba yi "piezoelectric effect". Isiphumo sayo esichaseneyo, oko kukuthi, ukuguquguquka kwe-elastic kweDielectric ebekwe kwindawo yombane, ibizwa ngokuba yi "inverse piezoelectric effect" okanye "electrostriction".
