Yintoni umahluko phakathi koluhlu olupheleleyo lwesithethi kunye ne-fractional frequency speaker?
一、fractional frequency speaker
Izithethi zokusasaza rhoqo, isithethi esineendlela ezimbini eziqhelekileyo, isithethi esineendlela ezintathu, ngokusebenzisa isahluli sefrikhwensi esakhelwe ngaphakathi, imiqondiso yomsindo yeereyithi ezahlukeneyo zefrikhwensi iyahlukaniswa, kwaye emva koko idluliselwe kwisithethi esihambelanayo. I-advanteji ye-frequency frequency speaker kukuba ibhendi nganye yefrikhwensi ineyunithi yayo yesandi, nganye isenza eyayo imisebenzi kwaye inika umdlalo kwiingenelo zayo zebhendi yefrikhwensi.

1,Isithethi esineendlela ezimbini
Isetyenziselwa i-acoustics yeshelufu yeencwadi, isithethi esiqhekezayo sineyunithi eyahlukileyo, kwaye i-bass ephakathi ixutywe kunye. Ngenxa yokuba iyunithi ye-treble kunye neyunithi ye-bass yahlukene, olu phawu lwesakhiwo lwenza ukuba ubuninzi bee-frequencies eziphezulu kunye nezisezantsi zibe ngcono, ukusuka kwi-solo yesixhobo ukuya kwi-symphony enkulu yokuhlanganiswa, inokubonakaliswa kakuhle.
2,Isithethi seendlela ezintathu
Ineyunithi eyongezelelweyo yesandi esiphakathi xa ithelekiswa nefrikhwensi yesibini, ngoko ke ikwanesandi esingcono sokusebenza. Ukuze kuphunyezwe isiphumo esifanelekileyo somgangatho wesandi, abaninzi abavelisi basebenza nzima kwindawo yokwahlulwa kwamaza. Ukukhethwa kwendawo yokwahlula amaza kufuneka kufakwe ngokweempawu zokuphendula rhoqo kwiyunithi yesithethi. Ukuba ayicwangciswanga kakuhle, iya kuchaphazela unikezelo lwamandla esandi, okukhokelela ekubeni isandi esipheleleyo singabi sicaba. Ngaphandle kweskimu solwahlulo lwezahlulo zenzululwazi kunye nengqiqo, nokuba ngesona sithethi sibalaseleyo, asinakuhlanganiselwa ukuba sisebenze. Kuphela ngolwahlulo oluneenkcukacha ezingakumbi, apho iyunithi ehambelanayo inokubuyisela isandi sebhendi nganye yamaza, kwaye ukusebenza komgangatho wesandi kuya kuba ngcono. Ngenxa yokuba kukho iiyunithi ezintathu rhoqo frequency, isahluli frequency kwakhona kufuneka entsonkothileyo ngakumbi, ixabiso eliphezulu, ixabiso isandi yomsindo ezintathu frequency kwimarike yangoku liwaka lokuqala yuan, uphawu elaziwayo lifikelele kwinqanaba leshumi lamawaka yuan, kunokuthiwa umkhuhlane awupheli. Okwangoku, zininzi iintlobo zeemveliso zesithethi sendlela yomoya, njenge-KTV yomsindo, ibhokisi yeshelufa yeencwadi, iaudio yethiyetha yomgangatho ukuya kumhlaba, njalo njalo.
二、uluhlu olupheleleyo lwesithethi
Njengoko igama libonisa, isithethi esipheleleyo sisebenzisa kuphela isithethi esipheleleyo sinokukhupha amaza aphezulu, aphakathi, aphantsi kunye nezinye zonke iifrikhwensi zesandi. Nangona ibizwa ngokuba yi-frequency epheleleyo, ayikwazi ukugubungela onke ama-frequency bands, i-frequency epheleleyo ibhekisela kuluhlu olubanzi lwe-frequency kunye ne-wide coverage.Isithethi soluhlu olugcweleyo Idigri yokudibanisa isithethi siphezulu, isigaba sichanekile, i-timbre ye-frequency band nganye idla ngokuhambelana, kwaye izinga lokuphazamiseka kwendlebe liphantsi. Ngokukodwa, ukusebenza kwenxalenye yefrikhwensi ephakathi kuhle kakhulu, kwaye isandi esikhutshwa ngabantu ikakhulu sikwizandi eziphakathi, ngoko ke ilizwi lomntu ligcwele kwaye lingokwemvelo. Ke ngoko, isithethi soluhlu olupheleleyo sisetyenziswa kakhulu kwiaudio yeTV (ibar yesandi), enokuphucula kwaye yandise iziphumo zesandi seeseti zeTV.
