Lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm kev kaw cia
Cov qauv ntawm cov ntaub ntawv kaw tseg yog tsim los ntawm cov neeg hais lus, microphones, kaw lus thiab cov khawm playback, lub ntsiab tswj IC, cov chips cia, Circuit Court boards, thiab khawm roj teeb.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub kaw lus tseem ceeb yog qhov sib txawv ntawm cov kab xev kaw lus. Lub kaw lus tseem ceeb hloov pauv cov teeb liab analog rau hauv cov teeb liab digital los ntawm digital-rau-analog converter los ntawm kev ua piv txwv thiab encoding lub analog teeb liab ntawm lub suab, thiab compresses nws cia. Cov teeb liab digital tsis cuam tshuam, thiab cov ntaub ntawv suab tsis ploj txawm tias tom qab ntau qhov kev tsim tawm.
Cov ntaubntawv povthawj siv thiab playback ntawm daim kab xev recorder yog ib tug electro-magnetic conversion txheej txheem. Thaum kaw, lub suab hluav taws xob teeb liab yog amplified thiab xa mus rau lub taub hau kauj, uas yuav ua rau alternating magnetic flux nyob rau hauv lub magnetic taub hau hlau core, thiab tsim ib tug magnetic teb uas hloov nrog lub zaus ntawm lub ua hauj lwm sib txawv ntawm lub magnetic head. Thaum cov kab hlau nplaum hla dhau los ntawm cov txheej hlau nplaum ntawm daim kab xev, nws magnetizes nws, yog li tawm hauv cov hlau nplaum seem, thiab raws li daim kab xev txav ntawm qhov nrawm, nws tawm ntawm daim kab xev txuas ntxiv ntawm polarity thiab lub zog uas hloov nrog lub suab. teeb liab Remanent sib nqus khiav, thiaj li hais tias lub teeb liab acoustic yog kaw nyob rau hauv daim ntawv ntawm remanence.
Lub suab zoo: Feem ntau lub suab zoo ntawm cov tub ntxhais kaw suab zoo dua li cov suab kaw suab. Lub kaw lus tseem ceeb feem ntau muaj cov ntaub ntawv kaw tseg xws li SP thiab LP. SP txhais tau tias ShotPlay yog hom luv luv. Txoj kev no muaj qhov tsawg compression tus nqi thiab lub suab zoo dua, tab sis lub sij hawm kaw yog luv. LP stands rau LongPlay, uas yog, ntev-lub sij hawm hom, nrog ib tug siab compression tus nqi, thiab lub suab zoo yuav raug txo kom tsawg.
Txoj kev khaws cia: Lub kaw lus tseem ceeb tau txais kev kaw lus analog, thiab lub cim xeeb hauv flash yog siv los khaws cov ntaub ntawv kaw. Cov yam ntxwv ntawm lub cim xeeb flash yog tias cov ntaub ntawv khaws cia rau ntawm nws yuav tsis ploj tom qab lub hwj chim raug tua. Nyob rau hauv txoj kev xav, nws tuaj yeem tiv taus ntau txhiab txhiab rov rov ua dua thiab rov sau dua, yog li tus nqi rov siv dua yog xoom. Koj tuaj yeem kaw suab paj nruag los ntawm kev txuas mus rau lub computer lossis xov tooj ntawm tes kom ua tiav cov neeg siv khoom txaus siab. Tus kheej kev cai suab paj nruag muaj nuj nqi.
