Ua haujlwm ntawm lub suab nrov
Lub suab nrov yog ib qho hluav taws xob hloov hluav taws xob uas hloov cov hluav taws xob hluav taws xob rov qab mus rau hauv lub suab, tom qab lub Zog Txheej Txheem hloov dua siab tshiab:Hluav Taws Xob → Neeg Kho Tshuab → Acoustic ZogCov. Noj cov feem ntauDynamic tsavUa piv txwv:
Electromagnetic Tsav
IbHloov pauv tam sim noLos ntawm cov audio ootifier ntws los ntawm tus hais lus lub suab raj. Muab tso rau hauv qhov chaw sib nqus muaj zog ntawm cov hlau nplaum ruaj khov, cov kauj kev paub sib txawv hloov lwm yam kev tawm tsamLorentz Zog Txoj Cai (F=bil), ua rau nws txav mus rov qab.
Neeg Kho Tshuab Kev Lom Zem
Lub suab cheeil yog rigidly txuas rau ib lub khob hliav qab / dome - zoo li tus duabdiaphragmCov. Lub axial lus tsa suab ntawm lub coil tsav lub diaphragm kom co synchronously. Cov ntaub ntawv diaphragm (ntawv pulp, hlau, lossis cov hlau, lossis cov khoom sib xyaw) sib npaug lub teeb ci ntsa iab nrog kev kub siab, thaum lubNkimMuab kev kho kom zoo dua kom ntseeg tau cov lus tsa suab thiab txo qis distortion.
Suab Whow Radiation
Raws li diaphragm txav mus rau pem hauv ntej, nws compresses cua los tsim ahigh - qhov siab cheeb tsam(COMPress yoj); Thaum rov ua dua tshiab, nws tsis tshua muaj cua los ua ibTsawg - qhov siab cheeb tsam(Rarsefaction yoj). Cov siab no hloov pauv kev sib tw raws liLongitudinal vuag, thaum kawg tau pom zoo li lub suab los ntawm tib neeg pob ntseg.
Hov ntauyog txiav txim siab los ntawm tus nqi ntawm kev hloov tam sim no (diaphragm kev co zaus).
Suab nrovNyob ntawm cov diaphragm lub amplitude (tam sim no siv).
Cov yam ntxwv tseem ceeb:
Magnetic field strength of the permanent magnet directly impacts drive efficiency (neodymium magnets: >1 tesla (t)).
Diaphragm Geometry (lub khob hliav qab / dome) ua kom zoo lub suab thoob plaws zaus.
Crossover System Xwb Tag Nrho - deb kos npe rau cov phiaj xwm tweets / woofers.
Cov txheej txheem no ua tiav kev tsim kho cov suab los ntawm cov cim hluav taws xob, ua rau lub suab nrov siv tau tawm hauv lub suab tso tawm.
