Loudspeaker tseem muaj npe hu ua" horn" ;. Yog cov khoom siv hluav taws xob hloov pauv ntau, hauv lub suab ntawm cov khoom siv hluav taws xob thiab hluav taws xob tuaj yeem pom hauv nws.
Kev nrov nrov yog ib qho tsis tshua muaj zog ntawm cov khoom siv hauv acoustics, tab sis rau acoustics, nws yog ib qho tseem ceeb tshaj plaws. Muaj ntau hom kev hais lus thiab lawv cov nqi sib txawv. Lub zog hluav taws xob hluav taws xob ua suab nrov los ntawm hluav taws xob, piezoelectric lossis electrostatic cuam tshuam uas co cov ntawv tais los yog diaphragm thiab resonate (resonate) nrog huab cua ib puag ncig. Raws li lub zog txauv txheej txheem thiab cov qauv txav ntawm cov coil hom (hom hluav taws xob), hom capacitor (electrostatic hom), hom piezoelectric (siv lead ua lossis ceramic), hom electromagnetic (siab caij nplooj ntoos hlav hom), hluav taws xob ion hom thiab pneumatic nrov, hluav taws xob nrov muaj zoo electroacoustic kev ua tau zoo, ruaj qauv, txiaj ntsig pheej yig, siv dav dav; Raws li cov khoom siv hluav taws xob hluav taws xob suab, ntawv phiab hom, naj npawb lub tog raj kheej hom, diaphragm hom; Raws li cov duab ntawm daim ntawv phiab, nws muab faib ua puag ncig, oval, ob chav ntawv phiab ntim thiab roj hmab folding nplhaib. Raws li kev ua haujlwm nquag ntawm cov ntses bass thaj tsam, nruab nrab, tsaws tshee, qee leej tseem muab faib ua cov kab xev kaw tshwj xeeb, TV tshwj xeeb, zoo tib yam thiab lub suab nrov nrov ntawm lub suab nrov, thiab lwm yam.; Lub suab co impedance tau muab faib ua qis impedance thiab siab impedance; Raws li cov nyhuv, nws tuaj yeem raug faib ua lub suab radial thiab ambient lub suab.
Loudspeaker tau muab faib ua lub suab nrov tsim sab hauv thiab sab nraud nrov nrov, thiab lub suab nrov sab nraud hais txog feem ntau yog lub suab ntim. Built-in hais lus yog hais txog qhov tseeb tias MP4 player muaj lub suab hais tawm kom tus neeg siv tau mloog lub suab tsim tawm los ntawm lub MP4 player tsis yog tsuas yog los ntawm lub mloog lub mloog nkaus xwb, tiam sis kuj dhau los ntawm cov lus sib txuas. Nrog tus hais lus MP4 tus ua si, koj tsis tuaj yeem xav tau cov neeg hais lus sab nraud, tab sis kuj tuaj yeem zam qhov tsis yooj yim ntawm lub sijhawm ntev nrog lub mloog pob ntseg.
