Tok i go pas
Hau long makim na plenim ol siling spika bilong kisim gutpela krai na ol VNETPA solusen
Ol 'ceiling speaker' i kamap olsem wanpela samting we ol i save yusim long ol nupela odio instolesen - maski em i bilong mekim musik long bekgraun insait long ol stua, 'paging' na toksave insait long ol opis, o 'clear voice reinforcement' insait long ol klasrum na miting rum. I no olsem ol tradisenel wol o plua spika, ol siling spika i save givim gutpela lukluk, i save pas gut wantaim ol samting insait long haus, na i ken givim wankain krai sapos ol i plenim gut.
1. Bilong wanem Plesmen na Kalkulesen i bikpela samting
Taim yu wokim wanpela odio sistem wantaim ol spika long siling, putim ol nating na i no save givim wankain krai. Gutpela plesmen i dipen long kliagut long sampela bikpela samting bilong spika:
● Hait bilong putim
Dispela em i longwe bilong man i toktok i go long level bilong man i harim. Siling we i antap moa i save mekim 'coverage area' i go bikpela tasol tu i save mekim 'sound attenuation' i go longwe.
● Reit Pawa
Pawa bilong wanpela spika (long watts) i makim hamas laud em inap kamap, tasol em i no makim stret hamas longwe krai bai go. Liklik pawa tumas inap long mekim nois i no strong tumas long arere bilong rum.
● Sensitivity
Ol i skelim long dB long wan wan wat long wan wan mita, na dispela i tokim yu long hau wanpela spika i save tanim pawa i go long krai. Bikpela sensitiviti i min olsem krai i save go longwe long wankain pawa level.
● Saon Angle
Angle bilong krai - we ol i skelim long digri - i makim hamas krai i go aut long wanpela spes. Ol bikpela angle i karamapim moa eria, tasol ol liklik angle i save tromoi krai i go longwe.
Taim yu bungim ol dispela samting, yu ken skelim hamas spika yu nidim na we yu ken putim ol long kisim gutpela kavrej.
2. Olsem wanem ol i save skelim 'ceiling spika kavrej'
Tingim wanpela spika we i stap 3 mita antap long plua wantaim 90 dB sensitiviti na 6 W pawa, na i laik kisim wanpela mak bilong krai bilong ~80 dB long olgeta hap bilong harim.
1. Distens we mak bilong SPL i kamap:
Yusim wanpela besik SPL fomula long skelim hamas longwe krai bilong spika i go pastaim long em i go daun long mak yu laikim.
2. Painimaut 'coverage radius':
Yu skelim tupela piksa - em 'theoretical omnidirectional range' na 'angular limit' we i kamap long 'dispersion angle' bilong spika - na kisim liklik namba olsem 'radius' bilong yu.
3. Kalkuletim eria we yu karamapim:
Kavrej eria em i wanpela sekol wantaim dispela 'radius' - we i gutpela long painimaut hamas spika yu nidim long pulapim rum bilong yu.
Long ol bikpela rum, ol i save putim ol spika wantaim 15%-20% 'overlap' namel long ol 'coverage zone' bilong abrusim ol "dead spot" bilong krai.
3. Introdiusim VNETPA Siling Spika
Taim kalkulesen i givim yu tingting, makim ol stretpela prodak i mekim disain bilong yu i kamap laip. VNETPA, wanpela kampani bilong Saina- we i save wokim ol netwok na PA odio solusen, i save givim kain kain siling spika we i gutpela long ol nupela instolesen.
Ol model we i stap long VNETPA
8W VoIP Siling Spika(Model NS-C008)
● Smol tasol gutpela disain
● Pawa-over-Ethernet (PoE) sapot i mekim wok bilong putim waya i kamap isi
● SIP-i stret long wok bung wantaim ol VoIP sistem
● Em i gutpela long ol opis, ol liklik miting rum, o ol stua we ol i nidim bekgraun musik na toksave
15W SIP Siling Spika(Model NS-C015)
● Bikpela autput bilong ol bikpela spes
● PoE na SIP i sapotim - gutpela tru long ol yunifaid komunikesen
● Em isi long putim na klinpela, waitpela pinis
● I wok gut insait long ol klasrum, ol 'lobby', o ol 'corridor' we i nidim klia 'voice paging'
Tupela bilong ol dispela opsen i ken stap olsem ol bikpela samting insait long wanpela 'paging system', 'corporate AV setup', o 'hospitality audio deployment'.
4. Ol gutpela tingting bilong plenim gut
✅ Oltaim larim sampela 'safety margin'.
Ol 'theoretical' kalkulesen i save tingim ol gutpela kondisen. Long ol gutpela ples we i gat ol fenija, ol samting we i save lait, o nois i stap klostu, em i gutpela long plenim liklik moa 'coverage' winim mak bilong 'math' i soim.
✅ Ovalapim ol spika i stap klostu liklik.
Liklik tumas 'overlap' i save kamapim ol spes long krai; planti tumas i min olsem yu westim nating. Wanpela 15%-20% 'overlap' i save skelim gut wok na kwaliti.
✅ Tingim mak bilong siling na yusim bilong en.
Insait long ol rum we i gat bikpela siling (olsem, ol oditorium), moa pawa na bikpela 'dispersion' i ken kamap long kisim gutpela harim.
5. Laspela Tingting
Ol 'ceiling speaker' i no ol samting we i stap hait tasol - planti taim ol i save stap olsem as bilong gutpela wok bilong putim musik, stat long ol stua na ol restoran i go inap long ol opis bilong ol bikpela kampani na ol ples bilong skulim ol manmeri. Taim yu bungim ol gutpela rot bilong plenim kavrej wantaim ol gutpela prodak olsem ol prodak bilong VNETPA, yu ken wokim ol odio sistem we i gat gutpela krai na i inapim ol samting yu mas putim.
Maski yu tingim klia toktok, maski musik i stap long baksait, o VoIP odio integresen, sapos yu kliagut long teknikel sait - wantaim makim stretpela 'hardware' - dispela bai mekim olgeta samting i senis long ol krai bilong yu.
