Isithethi esineendlela ezimbini sinezithethi ezibini, i-subwoofer kunye ne-tweeter. I-subwoofer kunye ne-tweeter zahlulwe yi-crossover kwaye zaqhagamshelwa kwi-subwoofer kunye ne-tweeter ngokwahlukeneyo.
Ukutshatisa iZakhono zeZithethi zeArray Line kunye neeMplifiers zamandla
Kwiinkqubo zeaudiyo zobungcali, kukuthelekiswa okufanelekileyo kuphela nokuchanekileyo okunokwenza isiphumo sokuqiniswa kwesandi esingcono, ngakumbi kwizithethi eziludwe lomgca. Ukuthelekiswa kwezikhulisi zamandla kubaluleke kakhulu. Namhlanje, i-Ding Taifeng Audio iya kwabelana nawe ngendlela yokumisela izixhobo zokukhulisa amandla kwizithethi eziloluhlu.
1. Impedance kufuneka ihambelane
Ukungqinelana nokungqinelana kuthetha ukuba isiphumo sokulinganiswa kwesiphumo sesikhulisi samandla kufuneka sihambelane nesantya sokulinganiswa kwesithethi somgca. Ukukhutshwa kwemveliso yesikhulisi samandla esiqhelekileyo ngokubanzi kuxhasa i-8Ω kunye ne-4Ω, kwaye ezinye izikhulisi zamandla zixhasa i-2Ω. Iziphumo zokungabikho kwemigca yezithethi zoluhlu ngokubanzi ziyahluka ukusuka kwi-16Ω kuye ku-8Ω. Ukuba izithethi ezibini zomgca zisetyenziswe ngaxeshanye ukunxibelelana nejelo elinye, ukungangqinelani kwesithethi somqolo womgca kuya kuba ngu-16Ω. Iba ngu-8Ω, njalo njalo. Ke ngoko, impedance yokukhutshwa kwesithethi esidwelisiweyo kunye nenani lonxibelelwano olufanayo kufuneka lihambelane nesiphumo sokukhutshelwa kwamandla.
Okwesibini, amandla kufuneka ahambelane
Umgangatho othile wolungelelwaniso lwamandla kunye nolwabiwo lomgca wesithethi kulwabiwo kukuba phantsi kweemeko ezithile zempembelelo, amandla alinganisiweyo wesikhulisi samandla kufuneka abe mkhulu kunamandla alinganisiweyo esithethi somtya, kunye namandla alinganisiweyo wesikhulisi samandla kwinkomfa Indawo yokuqinisa isandi kufuneka ibe ngama-1.2-1.5 amaxesha amandla alinganisiweyo esithethi somgca. Amandla alinganisiweyo kufanele ukuba abe li-1.5-2 lamaxesha amandla alinganisiweyo esithethi somgca wolayini xa isiphumo esinamandla sikhulu. Jonga lo mgangatho woqwalaselo, ongenakuqinisekisa kuphela ukuba isixhobo sokukhulisa amandla sisebenza phantsi kweyona meko intle, kodwa siqinisekise ukhuseleko lwezithethi zomgca.
3. Umgca wokudibanisa phakathi kwesikhulisi samandla kunye nesithethi somgca wokudibanisa kufuneka sihambelane
Intambo yesithethi kufuneka ibe mfutshane kangangoko ngokwamandla alinganisiweyo esithethi somtya, kunye nentambo yesithethi ekhethekileyo yesixokelelwano sobhedu kufuneka ichongwe ngononophelo xa uqhagamshela. Iplagi yesithethi esiludwe lomgca ngokubanzi ingumsebenzi wobuchwephesha abane okanye isiseko sesine Isithethi sixhuma ngaphezulu kwesiseko sinezithuba ezincinci kakhulu zokubopha, ke lumka xa unentambo.
