Hais Lus Txhais
Loudspeaker, feem ntau hu ua lub suab nrov, yog lub tshuab hluav taws xob electroacoustic uas tuaj yeem hloov hluav taws xob teeb liab mus rau hauv lub suab teeb liab thiab xa mus rau hauv huab cua.
Cov yam ntxwv ntawm lub tsheb hais lus
1. Kub: Qhov kub sib txawv loj, tiv taus qhov kub thiab txias
2. Humidity: noo noo-pov thawj (suab phiab)
3. Plua plav: plua plav pov thawj (dust cover)
4. Kev vibration: tsim kom ruaj khov
5. Suab nrov: suab nrov txo cov ntaub ntawv
6. impedance: Tsawg impedance
Tus neeg hais lus ua haujlwm txoj cai:
Thaum lub coil nyob rau hauv tus hais lus yog energized, nws yuav tsim ib tug magnetic teb. Nyob rau hauv kev sib cuam tshuam nrog cov hlau nplaum ntawm cov hlau nplaum, lub kauj yuav vibrate thiab tsim suab. Yooj yim muab, nws yog hais txog lub zog ua haujlwm ntawm tus neeg xyuas pib lub zog hauv qhov chaw sib nqus.
Kev faib cov neeg hais lus
(1) Los ntawm replay zaus:
① Tus hais lus ntau zaus: 20Hz-22kHz
② Lub suab hais lus siab: 5-22kHz
③ Tus hais lus nruab nrab: 80Hz-5kHz
④ Tsawg zaus hais lus: 16Hz-200Hz
(2) Nias diaphragm qhib:
① Cone zoo li tus hais lus;
② Pob sab saum toj hais lus;
③ Horn hom hais lus;
④ Siv hom hais lus.
(3) Raws li diaphragm loj:
Qhov loj me ntawm tweeter units (feem ntau yog xa mus rau txoj kab uas hla ntawm lub suab coil): 25mm (1in), 35mm (1.38), thiab lwm yam; Chav tsev qhov ntev ntawm nruab nrab mus rau qhov tsawg zaus hais lus (feem ntau yog xa mus rau txoj kab nruab nrab) suav nrog 80mm3in, 100mm4in, 130mm5in, 165mm6.5in, thiab lwm yam; Qhov loj ntawm chav tsev subwoofer (feem ntau, qhov loj ntawm lub subwoofer hais txog lub installation txoj kab uas hla) yog 200mm8in, 250mm10in, thiab 300mm12in.
(4) Los ntawm kev ua haujlwm:
Chav hais lus, teeb hais lus, coaxial hais lus, subwoofer.
Unit Speaker: Chav hais lus
Ib txheej ntawm cov neeg hais lus muaj xws li tweeters, nruab nrab cov neeg hais lus, zaus faib, thiab lwm yam. Feem ntau siv yog ob thiab peb qhov sib faib, uas muaj qhov zoo ntawm kev ua kom yooj yim rau qhov chaw ntawm lub suab.
Tus hais lus coaxial yog ib qho khoom siv uas tso tus neeg hais lus siab thiab nruab nrab ntawm lub coaxial lossis chassis. Yooj yim rau nruab thiab zoo ib yam suab qhov chaw.
Cov neeg hais lus ntses bass thaj tsam feem ntau tau teeb tsa rau hauv cov thawv tshwj xeeb uas tsim cov ntses bass thaj tsam nrog lub cheeb ntawm 200mm lossis ntau dua. Kev txhim kho kev mloog zoo hauv lub tsheb, tshwj xeeb tshaj yog thaum tsav tsheb ceev, cov ntses bass thaj tsam yuav raug txo kom tsawg, thiab yuav tsum tau ntxiv cov ntses bass thaj tsam.
Main Performance indicators, As hais lus
1. Rated zog thiab siab tshaj plaws;
2. zaus teb;
3. Distortion;
4. Rated impedance;
5. Kev xav;
100W tus qauv fais fab thiab ntim loj, lub zog yuav tsum tau thaum lub ntim thiab lub suab siab sib npaug:
X / 2 X / 1 X * 2 X * 4 (ntim)
