Yintoni iisithethi esipheleleyo?

Ukuqonda ngokupheleleyo ukuba yintoniisithethi esipheleleyoukuba, kubalulekile ukufunda ngesandi somntu. Isandi silinganiswa ngeHertz (Hz), okanye inani lamaxesha apho isignali yesandi iphakama ize ihle ngaphakathi komzuzwana. Izithethi ezisemgangathweni zakhiwe kwiifrikhwensi eziphezulu nezisezantsi kwinqanaba elivakalayo endlebeni yomntu. Indlebe yomntu iyakwazi ukuva zonke iifrikhwensi ukusuka kwi-20 Hz ukuya kwi-20 000 Hz (20 kHz).
Ukuze siqonde le ngcamango, singatsho ukuba izithethi ezithile zivelisa i-bass ebetha intliziyo kwi-20 Hz kunye nesignali ephezulu kakhulu kwi-20 000 Hz (20 Hz). Isithethi esipheleleyo siyakwazi ukuvelisa uninzi lwale frequency, ngaphakathi kwemida yaso yomzimba. Oko kuthetha ukuba uyilo lwesithethi lunokuchaphazela umgangatho we-a isithethi esipheleleyo.
 
Uluhlu lwefrikhwensi
 
Igama elithi “Full-Range” lithetha isithethi esigubungela lonke uluhlu lwelizwi lomntu. Uninzi lwezithethi ezipheleleyo zine-frequency ephantsi emalunga ne-60-70 Hz. Iiyunithi ezinkulu ezinee-driver ze-15” ziya kufikelela kwii-frequency eziphantsi, ngelixa ezo ze-driver ze-LF ze-10” okanye ngaphantsi ziya kuqengqeleka kufutshane ne-100 Hz. Uluhlu lwee-frequency eziphezulu zezi zixhobo ludla ngokufikelela kwi-18 kHz. Ke ngoko, izithethi ezincinci ezinee-driver ze-HF ezinobunzima obuphantsi ziya kuba nolwandiso lwe-range ngaphezu kweenkqubo zamandla aphezulu. Zinee-diaphragms ezinzima ukuhlangabezana neemfuno zazo zamandla. Uluhlu lwee-frequency eziphantsi zezi nkqubo aluyi kufuneka ukuba zenze umsebenzi ngokwazo kwicala elisezantsi. Zinokugqubana nee-subwoofers okanye mhlawumbi zinqunyulwe ngaphezulu kwe-LF cutoff yazo kwaye zikhululeke kwi-transmission ye-frequency ephantsi.
 
Ulwakhiwo
 
Ngokwesiqhelo, iyunithi yedrayivu epheleleyo inento enye yomqhubi, okanye i-voice coil, esetyenziselwa ukuhambisa nokulawula i-diaphragm. Ngokuqhelekileyo ulwakhiwo lwekhowuni luquka ukulungiswa kokuphucula ukusebenza kwe-high-frequency. Umzekelo, i-horn encinci enobunzima obuphantsi okanye i-Whizzer cone inokufakelwa apho i-voice coil kunye ne-diaphragm kudibana khona, ngaloo ndlela kwandisa imveliso kwi-high frequency. Imilo kunye nezinto ezisetyenziswa kwi-cone kunye ne-Whizzer ziphuculwe kakhulu.
Ukususela okoizithethi ezipheleleyoKufuneka ibe nempendulo ephezulu nephantsi, igubungela lonke uluhlu lwesandi xa kuthelekiswa nezinye izithethi. Kwi-high-frequency, ingabandakanya ikhoyili yelizwi elikhanyayo kunye noyilo lwekhabhinethi yetekhnoloji yee-frequency eziphantsi. Ingabandakanya nee-driver ezahlukeneyo ukuze kuphuculwe amava akho okumamela.

 
Umgangatho wesandi
 
Izithethi ezipheleleyo zinika amava amahle kakhulu esandi kwaye umgangatho ungcono kunowezithethi ezininzi ezisebenzisa iindlela ezininzi. Ukususwa kwe-crossover kunika esi sithethi amandla angakumbi okubonelela ngamava amnandi okumamela. Ngaphezu koko, kunika umgangatho kunye neenkcukacha kwiithoni eziphakathi. Nangona kunjalo, izithethi ezipheleleyo zorhwebo zinokuba zibiza kakhulu kwaye zinqabile. Kwezinye iimeko, abantu abasebenzisa izixhobo zomsindo banokufuna ukuzenzela iiyunithi zabo.

Isithethi esipheleleyo se-H-285
Inzuzo:
1. Umzimba webhokisi wamkela iipleyiti ze-splint kunye nesakhiwo esikhethekileyo soqhagamshelo lwepleyiti ukuze kupheliswe ukuvakala komoya womzimba webhokisi ozivelelayo.
