Mashandiro anoita vakurukuri

1. Magnetic speaker ine electromagnet ine simbi inofambiswa pakati pematanda maviri echigarire magineti.Kana pasina ikozvino mucoil ye electromagnet, iyo inofambiswa iron core inokwezvwa nechikamu-chikamu chinokwezva chemagineti mapango echigarire magineti uye inoramba yakamira pakati;Kana yazvino ichiyerera nepakati pecoil, iyo inofambiswa simbi musimboti inoiswa magineti uye inova bar magineti.Nekuchinja kwekwazvino kutungamira, iyo polarity yebhari magineti inochinjawo zvinoenderana, kuitira kuti inofambiswa simbi musimboti inotenderera ichitenderedza fulcrum, uye kuzunguzika kweiyo inofambiswa simbi musimboti inofambiswa kubva ku cantilever kuenda kune diaphragm (bepa cone) kusunda mhepo kuti iite kuzunguzika.

2. Electrostatic speaker Chitauriri chinoshandisa simba re electrostatic rakawedzerwa kune capacitor plate.Mukutaura kwechimiro chayo, inonziwo capacitor speaker nokuti ma electrode akanaka uye asina kunaka anopesana kune mumwe nemumwe.Zvinhu zviviri zvakakora uye zvakaoma zvinoshandiswa semahwendefa akagadziriswa, anogona kufambisa ruzha kuburikidza nemahwendefa, uye ndiro yepakati inogadzirwa nezvinhu zvitete uye zvakareruka semadiaphragms (akadai sealuminium diaphragms).Gadzirisa uye simbisa kutenderedza diaphragm uye chengeta chinhambwe chakati wandei kubva padanda rakagadziriswa.Kunyangwe pane diaphragm hombe, haizopesani nedanda rakagadziriswa.
3. Vatauri vepiezoelectric Mutauri anoshandisa inverse piezoelectric effect ye piezoelectric zvinhu anonzi piezoelectric speaker.Chiitiko chekuti dielectric (yakadai sequartz, potassium sodium tartrate uye mamwe makristasi) inogadziriswa pasi pechiito chekumanikidza, zvichiita kuti pave nemusiyano pakati pemigumo miviri yepasi, iyo inonzi "piezoelectric effect".Mhedzisiro yaro, kureva, elastic deformation ye dielectric yakaiswa mumunda wemagetsi, inonzi "inverse piezoelectric effect" kana "electrostriction".
