Tok i go pas
Insait long ol komesal na pablik spes olsem ol klasrum, opis, kafe, o korido, ol spika we ol i save putim long wol em ol samting we yu ken makim bilong putim bekgraun musik, pablik tokaut, pejing, na moa. Stretpela instalesen bilong ol na ol kain kain 'coverage pattern' i mekim ol i gutpela long ol hap we ol i no inap o ol i no laikim long putim siling.
Tasol gutpela krai em i no long baim ol spika na putim ol nating tasol. Gutpela plening - stat long kalkuletim ol 'coverage areas' i go inap long makim ol stretpela model - i mekim gutpela kwaliti bilong krai long olgeta spes. Aninit, mipela i bungim ol gutpela tingting bilong plenim musik wantaim ol gutpela prodak bilong VNETPA, wanpela gutpela kampani bilong wokim ol PA spika we ol i save putim long wol.
Wanem samting i save stiaim toktok bilong ol spika?
Pastaim long yu putim, em i gutpela long kliagut long sampela as samting:
1. Hait bilong putim
Vertikal distens namel long spika i go long man i harim i save senisim hamas krai i go aut. Putim antap tumas na odio eneji inap long lusim ol bikpela hap bilong harim; i daunbilo tumas na kavrej i go liklik.
2. Pawa na Sensitiviti
● Rated Power (W) i save stiaim hamas laud sistem inap long go, we i save stiaim hamas klia krai i ken raun.
● Sensitivity (dB/W/m) i tokim yu long hau wanpela spika i save tanim pawa i go long krai. Bikpela sensitiviti i save min olsem yu inap long kisim gutpela samting.
3. Kavrej Angle
Horisontal na vertikal saon dispersen bilong spika i save makim hamas plua eria wanpela yunit inap long karamapim. Ol bikpela angle i save spredim krai i go long planti hap tasol i ken daunim strong bilong krai; ol liklik angle i save mekim narapela samting.
Ol dispela samting i bikpela samting taim yu skelim hamas spika yu nidim na hamas longwe ol i mas stap. Olsem, ol odio enjinia i save disainim ol spika we i stap klostu na bai ol eria bilong kavrej i karamapim 10-15% bilong abrusim ol odio ded zon.
Skelim Kavrej: Wanpela Simpol Eksampel
Tingim wanpela spika we i stap antap long 2.5 mita wantaim:
• 90 digri horisontel kavrej
• 91 dB sensitiviti
• 6 W pawa
• SPL (level bilong harim): 80 dB
Yu ken yusim ol standet fomula bilong indastri, yu ken painim mak bilong 'effective radius' we krai i stap long o antap long 80 dB - klostu 8.7 m long dispela taim. Dispela i min olsem wanpela 'coverage area' inap olsem 59 m2 long wan wan spika.
Wantaim dispela, yu ken stat long plenim spes bilong ol spika na namba olgeta - maski em i wanpela longpela korido o wanpela rum we i gat planti wok.
Wall-Mounted Spika Solusen bilong VNETPA
VNETPA, we i stap long Xiamen, Saina, i save wok long IP-enabled odio pablik adres na SIP-kompatibel wol-spika, we i gutpela long ol moden netwok PA sistem. Ol prodak lain bilong ol i karamapim planti kain wol spika we ol i wokim bilong ol kain kain envairomen:
Klasrum na liklik spes spika
● 15W Network Wooden Wall Mounted Spika (NS-W015) - i liklik tasol em i gutpela long putim long ol toksave insait long klasrum o musik i no strong tumas.
● 30W Netwok Wol Mounted Spika (NS-W130) - i sapotim Power-over-Ethernet (PoE) na SIP alam input. Em i gutpela we netwok kontrol na isipela setup i bikpela samting.
Ol bikpela gutpela samting bilong ol VNETPA wol spika:
● Ol i wokim bilong SIP na IP i go insait long ol moden PA sistem
● Sapotim indastri standet netwok pawa na kontrol opsen
● Klinpela fom fakta we i gutpela long ol klasrum, opis, stua, na ol 'lobby'
● Wok bilong wokim ol samting i stap stret long ol wok bilong projek
Laspela Tips bilong Great Wall Spika Pefomens
● Simulation sofwet (olsem EASE o ol narapela) inap long stretim layout bilong yu sapos yu wok long disainim wanpela kompleks sistem o hai-instolesen.
● Tingim olsem ol ples we i stap tru - ol fenija, siling, na seip bilong rum - i save senisim hau krai i save raun, olsem na ol wok sekim long sait em i bikpela samting tru.
● Painim ol spika bilong yu wantaim ol netwok PA hatwea na ol kontrol we i ken wok wantaim long mekim isi menesmen bilong 'zone' na 'emergency paging'.
