Tsab xov xwm no tshawb nrhiav seb cov kab array audio systems tuaj yeem tsim kev paub suab zoo li cas, kom ntseeg tau tias txhua lub ces kaum ntawm qhov chaw puv nrog cov suab nrov zoo kawg.
Nkag Siab Txog Kab Array Audio Systems
Ib lub tshuab suab kab array muaj ntau lub tshuab hais lus uas teeb tsa ntsug. Qhov kev teeb tsa no tso cai rau kev tswj hwm zoo dua ntawm kev tawg ntawm cov nthwv dej suab dua li cov qauv hais lus ib txwm muaj. Kev tsim ntawm ib lub tshuab hais lus kab array ua rau nws tuaj yeem tso suab mus deb thaum tswj hwm qhov meej thiab sib xws. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov chav ua yeeb yam loj, cov chaw ua yeeb yam, thiab cov xwm txheej sab nraum zoov uas lub suab xav tau mus txog txhua tus neeg tuaj saib sib npaug.
Qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov kab array systems yog lawv lub peev xwm los tswj kev sib kis suab. Siv cov thev naus laus zis siab heev, cov kab ke no tuaj yeem tsom lub zog suab rau hauv ib qho kev taw qhia tshwj xeeb, txo qhov kev cuam tshuam thiab cov suab rov qab uas tuaj yeem cuam tshuam rau qhov zoo ntawm lub suab. Qhov kev tswj hwm kev coj ua no ua kom lub suab ncav cuag cov neeg tuaj saib nrog qhov tseeb, tsim kom muaj kev paub zoo uas paub tseeb tias yuav ua rau koj nkag siab.
Lub suab zoo kawg nkaus los ntawm kev siv tshuab line array
Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm cov kab suab array yog lawv lub peev xwm los muab lub suab zoo. Txawm hais tias nws yog kev hais kwv txhiaj nyob, kev ua yeeb yam lossis kev tshwm sim hauv tuam txhab,suab zooyog qhov tseem ceeb tshaj plaws. Cov kab arrays ua tau zoo hauv thaj chaw no, muab cov suab tso tawm sib npaug, dynamic uas txhim kho qhov chaw tag nrho.
1. Kev faib suab sib xws: Cov kab ke kab yog tsim los muab kev npog suab sib xws thoob plaws thaj chaw dav. Qhov no txhais tau tias txawm cov neeg tuaj saib nyob qhov twg los xij, lawv yuav muaj lub suab zoo ib yam. Qhov kev sib xws no yog qhov tseem ceeb rau kev tsim kom muaj ib puag ncig zoo vim nws ua kom muaj suab zoo sib xws txawm tias koj nyob qhov twg los xij.
2. Kev meej thiab kev nthuav dav zoo dua:Cov kab ke kab sib dhossiv cov txheej txheem engineering siab heev kom ua tiav qhov kev tsim suab meej dua thiab nplua nuj dua. Qhov no tseem ceeb heev rau cov teebmeem suab me me, xws li lub suab nrov ntawm nplooj lossis lub suab nrov ntawm xob laim deb. Cov kab ke kab tuaj yeem khaws cov ntsiab lus no, ua rau cov neeg tuaj saib nkag siab tag nrho hauv kev ua yeeb yam.
3. Qhov ntau thiab tsawg Dynamic: Cov kab ke kab sib dhos muaj peev xwm tswj tau qhov ntau thiab tsawg dynamic, txhais tau tias lawv tuaj yeem ua kom zoo dua ob qho tib si suab mos thiab nrov yam tsis muaj kev cuam tshuam. Lub peev xwm no yog qhov tseem ceeb rau kev tsim cov suab muaj zog uas cuam tshuam nrog cov neeg tuaj saib. Piv txwv li, qhov tawg ntawm rab phom loj hauv kev ua yeeb yam lossis lub suab mos mos ntawm tus cwj pwm tuaj yeem nthuav tawm nrog qhov tseeb sib npaug, txhim kho kev cuam tshuam ntawm kev ua yeeb yam.
4. Txo cov lus teb rov qab thiab kev cuam tshuam: Ib qho ntawm cov teeb meem ntawm kev txhawb nqa lub suab nyob yog tswj cov lus teb rov qab thiab kev cuam tshuam. Cov kab ke kab sib dhos tau tsim los txo cov teeb meem no, ua rau lub suab meej dua. Qhov no tseem ceeb heev rau cov chaw uas siv ntau lub microphones, vim nws ua kom cov suab zoo sib xyaw ua ke thiab zam kev suab nrov tsis tsim nyog.
Lub luag haujlwm ntawm cov khoom siv suab hauv cov kab array systems
Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws los ntawm lub kaw lus suab kab, qhov zoo ntawm cov khoom siv suab siv yog qhov tseem ceeb heev. Cov amplifiers zoo,cov khoom sib tov, thiab cov chav ua haujlwm ua haujlwm ua ke nrog cov neeg hais lus kab array los tsim kom muaj kev paub suab zoo. Nov yog qee qhov tseem ceeb uas cuam tshuam rau qhov zoo ntawm lub suab:
- Cov amplifiers fais fab: Muaj zogcov amplifiersyog qhov tseem ceeb rau kev tsav tsheb kab array systems. Lawv muab lub zog tsim nyog los xyuas kom meej tias lub suab tau tso tawm ntawm qhov ntim xav tau yam tsis muaj kev cuam tshuam. Lub amplifier zoo tuaj yeem txhim kho qhov ntau thiab tsawg thiab qhov tseeb ntawm lub suab, ua rau nws muaj txiaj ntsig zoo dua.
