Kurongwa kwemamwe maodhiyo amplifiers
Pazasi iwe unowana tsananguro dzega ega marudzi evatauri uye maikorofoni uye kupatsanurwa kwavo zvinoenderana nemusimboti wekushanda.
Kuparadzaniswa kwemagudzanzwi maererano nemusimboti wekushanda.
Magnetoelectric (yakasimba) - conductor (magnetic coil), kuburikidza nemagetsi emagetsi anoyerera, anoiswa mune magnetic field yemagineti. Kudyidzana kwemagineti uye conductor ine ikozvino kunokonzera kufamba kwemuitisi kune iyo membrane inosungirirwa. Iyo coil yakabatana zvakasimba kune diaphragm, uye zvese izvi zvakamiswa nenzira yekuti ive nechokwadi chekuti axial kufamba kwekoiri mugeji remagineti pasina kupokana nemagnet.
electromagnetic - Iyo acoustic frequency ikozvino kuyerera inogadzira inochinjana magineti. Iyo inobata ferromagnetic musimboti wakabatana neiyo diaphragm, uye kukwezva uye kudzoreredza kwepakati kunoita kuti diaphragm izununguke.
Electrostatic - membrane ine magetsi yakagadzirwa nefoil yakatetepa - ine simbi yakaiswa kune rimwe kana mativi ese kana kuve electret - inobatwa nemagetsi maviri ane perforated ari pamativi ese efoil (pane imwe electrode, chiratidzo chechiratidzo chinoshandurwa 180 degrees ne rukudzo kune imwe), semhedzisiro iyo Iyo firimu inodedera nenguva nechiratidzo.
magnetostrictive - iyo magineti inokonzera shanduko muhukuru hweiyo ferromagnetic zvinhu (magnetostrictive phenomenon). Nekuda kwehurefu hwemasikirwo emhando dzeferromagnetic, rudzi urwu rwegudzanzwi rinoshandiswa kugadzira Ultrasound.
Piezoelectric - nzvimbo yemagetsi inokonzera kuchinja kwezviyero zvepiezoelectric zvinhu; inoshandiswa mu tweeters uye ultrasonic madivayiri.
Ionic (isina membrane) - rudzi rwe diaphragmless speaker umo diaphragm basa rinoitwa nemagetsi arc inobudisa plasma.
Mhando dzemakrofoni
Acid - tsono yakabatana ne diaphragm inofamba mu dilute acid. Kubata (kabhoni) - kuvandudzwa kwemaikorofoni asidhi umo asidhi inotsiviwa nekabhoni granules inoshandura kuramba kwavo pasi pekumanikidzwa kunoitwa ne membrane pane granules. Mhinduro dzakadaro dzinowanzoshandiswa mumafoni.
Piezoelectric - a capacitor inoshandura acoustic signal mumagetsi emagetsi.
Dynamic (magnetoelectric) -kuzunguzika kwemhepo kunogadzirwa nemasaisai eruzha kunofambisa diaphragm yakatetepa uye yakabatana coil yakaiswa musimba remagineti rinogadzirwa nemagineti. Nekuda kweizvozvo, voltage inoonekwa pamakoiri terminals - simba re electrodynamic, i.e. kudengenyeka kwemagineti yecoil, yakaiswa pakati pemapango, inokonzera magetsi mairi ine frequency inoenderana nehuwandu hwekudengenyeka kwemafungu ekurira.
Yanhasi isina waya maikorofoni
Capacitive (electrostatic) - Iyi mhando yemakrofoni ine maelectrode maviri akabatana kune inogara voltage sosi. Imwe yacho haipfakanyiki, uye imwe yacho ine membrane inobatwa nemasaisai eruzha, ichikonzera kuti iite zvekubvunda.
Capacitive electret - kusiyanisa kwemakrofoni ye condenser, iyo iyo diaphragm kana yakagadziriswa lining yakagadzirwa ne electret, i.e. dielectric nekugara kwemagetsi polarization.
High frequency capacitive - inosanganisira yakakwira-frequency oscillator uye symmetrical modulator uye demodulator system. Shanduko yehukwanisi pakati pema electrode emaikorofoni inogadzirisa amplitude yezvikwangwani zveRF, kubva ipapo, mushure mekudzikiswa, chiratidzo chepasi-frequency (MW) chinowanikwa, chinoenderana nekuchinja kweacoustic pressure pa diaphragm.
Laser - mune iyi dhizaini, iyo laser beam inoratidzwa kubva panzvimbo inodedera uye inorova iyo photosensitive chinhu cheanogamuchira. Kukosha kwechiratidzo kunoenderana nenzvimbo yedanda. Nekuda kwekubatana kwepamusoro kweiyo laser beam, iyo membrane inogona kuiswa kure kure kubva kune danda rekutamisa uye rinogamuchira.
Optical fiber - chiedza chechiedza chinopfuura nepakati pekutanga optical fiber, mushure mekufungisisa kubva pakati pe membrane, inopinda pakutanga kwechipiri optical fiber. Kuchinja-chinja kwe diaphragm kunokonzera shanduko mukusimba kwechiedza, izvo zvinobva zvashandurwa kuita chiratidzo chemagetsi.
Maikorofoni yeasina waya masisitimu - mutsauko mukuru mukugadzirwa kwemakrofoni isina waya inongova mune imwe nzira yakasiyana yekutumira chiratidzo pane mune wired system. Panzvimbo petambo, transmitter inoiswa mune iyo kesi, kana yakaparadzana module yakasungirirwa kune chiridzwa kana kutakurwa nemuimbi, uye inogamuchira iri padyo neiyo yekusanganisa console. Iwo anonyanya kushandiswa transmitters anoshanda muFM frequency modulation system muUHF (470-950 MHz) kana VHF (170-240 MHz) mabhendi. Iyo inogamuchira inofanira kusetwa kune imwe chiteshi semaikorofoni.
