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 esiphindwe kabini 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 ngamaza eyunithi yesithethi.Ukuba ayicwangciswanga kakuhle, iya kuchaphazela unikezelo lwamandla esandi, okukhokelela ekubeni isandi esipheleleyo singabi sicaba.Ngaphandle kweskimu solwahlulo lwezahlulo zenzululwazi kunye nengqiqo, nokuba ngeyona yunithi yesithethi igqwesileyo, ayinakuhlanganiselwa ukuba isebenze.Kuphela ngolwahlulo oluneenkcukacha ezingakumbi, apho iyunithi ehambelanayo inokubuyisela isandi sebhendi nganye yamaza, kwaye ukusebenza komgangatho wesandi kuya kuba ngcono.Ngenxa yokuba kukho iiyunithi ezintathu eziphindaphindayo, isahluli esiphindaphindayo sikwafuna ukuntsonkotha ngakumbi, ixabiso liphezulu, ixabiso lesandi se-audio yefrikhwensi ezintathu kwimarike yangoku liwaka leeyuan isiqalo, uphawu olwaziwayo lufikelele kwinqanaba leeyuan lamawaka alishumi, kunokuthiwa umkhuhlane awupheli.Okwangoku, zininzi iintlobo zeemveliso zesithethi sendlela yomoya, njenge-KTV audio, ibhokisi yeshelufa yeencwadi, umgangatho womgangatho ukuya kumhlaba wethiyetha yasekhaya 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 ngamaza ohlobo olupheleleyo, ayinakugubungela zonke iibhendi zamaza, i-frequency epheleleyo ibhekiselele kuluhlu olubanzi lwefrikhwensi kunye nobubanzi obubanzi.Isithethi soluhlu olupheleleyo Idigri yokudibanisa isithethi iphezulu, isigaba sichanekile ngokwentelekiso, i-timbre yebhendi nganye iyathandeka. ukuhambelana, kwaye izinga lokuphazamiseka kweendlebe 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 esipheleleyo sisetyenziswa kakhulu kwiaudio yeTV (ibar yesandi), enokuphucula kwaye iphucule iziphumo zesandi seeseti zeTV.
