Abakwa-Breaking Down Car Speakers
I-coaxial, noma uhla olugcwele, futhi ingxenye yizigaba ezimbili ezibanzi zezipikha ezingasetshenziswa uma kwakhiwa, noma ukuthuthukiswa, izinhlelo zomsindo zezimoto. Uhlobo oluvame kakhulu yilona isikhulumi se-coaxial, esitholakala cishe kuzo zonke izinhlelo ze-OEM ze- stereo ezihamba emgqeni. Lezi zikhulumi ziqukethe umshayeli ongaphezu kweyodwa, ezivumela ukuba zikhiqize ama-frequencies ahlukahlukene. Izikhulumi ezihlangene azivamile, kodwa ama-audiophiles ngokuvamile athembele kuwo lapho ekwakheni izinhlelo zokusebenza zomsindo wemoto. Lezi zikhulumi zenziwa ngomshayeli oyedwa, ngakho zenzelwe ukuthi zikhiqize kuphela, eziphakathi, noma amathoni aphansi.
Yini Abakhulumi Abakhi?
Ububanzi bokuzwa kwabantu buphakathi kuka-20 kuya ku-20,000 Hz, futhi lo mdlalo ngokuvamile uhlehlisiwe ube yizigaba eziningana uma kuziwa nobuchwepheshe besipikha. Izikhulumi ezihlangene ziphethe isigaba esisodwa, noma ingxenye, yalolu hlu. Ama-frequencies aphezulu adalwa ama-tweeters, aphansi kunawo wonke ama-woofers, kanye nezikhulumi eziphakathi kwamaphakathi afanele phakathi kwalawo maqhinga. Njengoba izikhulumi zendawo ziqukethe eyodwa ikhamera eyodwa nomshayeli oyedwa, zihambisana kahle kulezo zigaba.
Abathengisi
Lezi zikhulumi zimboza ukuphela okuphezulu kwe-spectrum yomsindo kusuka ku-2,000 kuya ku-20,000 Hz. Ukunakwa okuningi kunakhokhwa kuma-bass, kepha ama-tweeters aphezulu ahlale edlala indima ebalulekile ekugcwaliseni umsindo wezwi. Lezi zikhulumi zibizwa ngokuthi yi-tweeting ephakeme kakhulu yezinyoni.
Phakathi kwebanga
Ububanzi obuphakathi kwe-spectrum ezwakalayo inemisindo ewela phakathi kuka-300 kuya ku-5,000 Hz, ngakho-ke kukhona okungafani phakathi kwezikhulumi eziphakathi kwebanga no-tweeters.
Woofers
Ama-deep bass, awela ebangeni elilinganiselwa ku-40 kuya ku-1,000 Hz, liphathwa yi-woofers. Kukhona nokunye okungafani phakathi kwama-woofers kanye nezikhulumi eziphakathi kwebanga, kepha phakathi kwamabanga ngokuvamile akakwazi ukukhiqiza izinsimbi ezifana nezinja ezinikeza igama lazo.
Kukhona nezimpikiswano ezimbalwa eziyingxenye ezikhethekile ezinganikeza ukwethembeka okungeziwe ekugqibeleni kwe-spectrum yomsindo.
Abaphuzi abakhulu
Lezi zikhulumi ngezinye izikhathi ziyakwazi ukukhiqiza ama-ultrasonic frequencies ezingaphezu kwezinga elijwayelekile lokuzwa kwabantu, futhi iziphetho zabo ezingezansi ziphakeme kakhulu kunama-2,000 Hz ukuthi ama-tweeters avamile abamba. Lokho kuvumela ama-super tweeters ukuba akhiqize imisindo ephezulu yemvamisa ngaphandle kokuphazamiseka.
Ama-subwoofers
Njengama-tweeters amakhulu, ama- subwoofer s aklanyelwe ukunikeza umsindo ophezulu wekhwalithi ekupheleni kokuphela kwe-spectrum ye-audio. Ama-subwoofers ebanga labathengi ngokuvamile asebenza ebangeni kusukela ku-20 kuya ku-200 Hz, kodwa imishini yomsindo ingakwazi ukukhawulelwa kuma-frequencies angaphansi kwama-80 hz.
Yini Abakhulumi BeCoaxial?
Izikhulumi ze-coaxial zivame ukubizwa ngokuthi "izibukeli ezigcwele" ngoba zenzelwe ukukhiqiza ububanzi obuningi bama frequency kusuka kulelo linye. Lezi zikhulumi ziqukethe izinhlobo ezifanayo zamashayeli ezitholakala kuzikhulumi zenkampani, kodwa zihlangene ukugcina imali nemklomelo. Ukumiswa okuvame kakhulu kuwu-woofer nge-tweeter ephakanyiswe phezulu, kepha kunezikhulumi ze-coaxial ezi-3 eziqukethe i-woofer, ububanzi obuphakathi no-tweeter.
Izikhulumi zezimoto zeCoaxial zaziswa ekuqaleni kwawo-1970, futhi izinhlelo eziningi ze-OEM ze-audio manje zisebenzisa izikhulumi eziphelele, ngoba umklamo wesistimu ye-OEM yemoto ngokuvamile ubeka phambili izindleko ngekhwalithi. Lezi zikhulumi nazo zitholakala ezihlinzekweni ezihlukahlukene zomsakazo wemoto we-aftermarket, futhi ukufaka esikhundleni izikhulumi zezimoto zamakhamera ngezinyunithi eziphezulu ze-aftermarket ngokuvamile kuvamise ukuthuthukiswa kokulalelwayo kwemoto yemoto .
Ingabe Abakhulumi Bamakheli Noma Abakhulumi BamaCoaxial Kungcono Ezimoto?
Izikhulumi ezihlangene nezama-coaxial zinezinzuzo kanye nezinselelo, ngakho-ke akukho impendulo elula yombuzo ongcono. Amanye amaphuzu anamandla anikezwa yi-option ngayinye afaka:
Izikhulumi ze-coaxial eziphelele zebala:
- engabizi kakhulu
- ukulingana okuqondile
- Awudingi ama-crossovers
Ingxenye:
- ikhwalithi yomsindo ophakeme
- ukwenza ngokwezifiso ngokwengeziwe
Izikhulumi ezakhiwe zingcono nakakhulu ngokuhambisana nekhwalithi yomsindo, kodwa izikhulumi zezinhla zokugcwele azibiza kakhulu futhi kulula ukufaka. Njengoba izinhlelo eziningi ze-OEM zisebenzisa izikhulumi eziphelele zezinhlawulo, ukuthuthukiswa ngokuvamile kuyindaba yokwehlisa izikhulumi ezintsha .
Uma isabelomali noma lula ukufaka ukukhathazeka okuyinhloko, izakhamuzi eziphelele zezintaba zizoba yisinqumo esihle kakhulu. Izikhulumi eziphezulu eziphezulu zezinga eliphezulu angeke zikwazi ukufanisa noma ukushaya izikhulumi zezingxenye, kepha zingakwazi ukunikeza isipiliyoni esihle sokulalela.
Noma kunjalo, izikhulumi zenkampani zinikeza ithuba elikhulu ngokwezifiso. Ngaphandle kokuthi izikhulumi zezinhlangothi zihlinzeka ngekhwalithi ezwakalayo engcono, isikhulumi ngasinye singabekwa eceleni ukuze senze i-soundscape enhle yemoto ethile. Uma izinga elizwakalayo libaluleke ngaphezu kwesabelomali noma isikhathi, izikhulumi zezinhlangothi ziyindlela yokuhamba.
