Three-indlela futhi ezimbili indlela izikhulumi: izici, izinzuzo, umehluko

Kwimakethe izikhulumi ethulwa yebanga kahle esikhulu. Lokhu imishini kuhlukile nomunye kwenkululeko (ithuluzi, ikhonsathi, studio, njll) ngokuhambisana nezimiso kanye uhlobo sikebhe nezinye izimfanelo eziningi. Umngcele we-ezibaluleke kakhulu okufanele kubhekwe kwasekuqaleni, inombolo "Amabha" ohlelweni. Ngokusho lokhu umbandela, ovelele esalisekela, amathathu- futhi ezimbili indlela izikhulumi. Bawenza kanjani ihluke nomunye futhi okuyinto uhlelo kungcono, sizozama ukuphendula kule athikili.

Imvamisa umsindo

izitho Engumuntu ukuzwa bayakwazi ukubona imisindo imvamisa ka 20 ku-20,000 Hz. Ngakho-ke, ikhwalithi umculo kuncike ikhono imishini ukudala amagagasi omnandi umsindo kububanzi obunikeziwe. Ngenxa yale njongo, e isikhulumi siqala ukubeka ukufaka izikhulumi nokuzala eliphansi kakhulu (20-150 Hz), eliphakathi (100-7000 Hz) kanye okusezingeni eliphezulu (5-20 ayizinkulungwane. Hz) amaza. Kule ndaba, kwakunabamemezeli:

1. SSB uhlelo, lapho wonke imvamisa uhla yakha eyodwa isikhulumi.
2. Ababili-indlela izikhulumi, esesikhundleni izipikha ezimbili ezingafani: kuletha ukudlala umculo medium and imisindo ephansi, kanti eyesibili - okusezingeni eliphezulu kuphela.
3. kwindlela-Three imishini - yokudlala umsindo osebangeni ngamunye oluhambisana "ikholomu" ehlukile.

Kukhona imishini nge eziningi bands, lapho isikhulumi ngasinye eveza ezizwakalayo ezithile imvamisa ububanzi. Ethandwa kakhulu babe ezimbili futhi kwindlela emithathu uhlelo - Zingamashumi ezingabizi kakhulu futhi ngesikhathi esifanayo ukunikeza omuhle kakhulu izinga umsindo.

Izinzuzo ezimbili ngendlela Izikhulumi

Ababili-indlela izikhulumi ethandwa kakhulu phakathi abashayeli. Zinikeza elikhulu izinga umsindo ngesikhathi esifanayo babe ngentengo ephansi. Ngenxa ukuthuthukiswa ezimbili indlela ubuchwepheshe Acoustics ngenkuthalo dengwane imishini emithathu band, kodwa namanje obudlange ngoba amathuba abo:

1. Umklamo elula, okuyinto lula ukufakwa kanye ukucushwa.
2. Izinga eliphezulu efanayo phakathi izipikha, okuholela izinga olukhuthaziwe umsindo.
3. Engokwemvelo kakhulu, umsindo "bukhoma".

Imishini onemizila emibili abantu bomdabu ezimbili kuphela - bass futhi zonxantathu. Bass isikhulumi ukhiqiza umsindo ku amabanga aphansi kanye maphakathi, futhi RF - okusezingeni eliphezulu kuphela. Ngenxa lokhu ohlelweni kudingeka elula crossover amanethiwekhi.

Izici imishini emithathu band

Three-indlela isikhulumi lihlukile uhlelo kakade kuchazwe umsindo umhlabeleli. Isisetshenziswa izinhlelo ezifana doukomplektovyvaetsya Midrange umshayeli, esizolokhu okuthiwa Imininingwane "ngekwendzawo" kudala umsindo ozungezayo. Ngaphezu kwalokho, ngenxa ukwehlukana imisebenzi, imishini isibe ezincane. izinga Negative emithathu band izinhlelo yinani eliphezulu. Kuyinto, kabili kuya kulokutsatfu kunakunoma ezimbili ngendlela izikhulumi. Ngaphezu kwalokho, ezintathu-indlela udluliseleke crossover kuhilela ukufakwa - eziyinkimbinkimbi imvamisa izihlungi. Ukuze usethe i-imishini enjalo kumele babe ukuzwa kakhulu, noma ukufeza ukungaguquguquki zezikhulumi ngeke zisebenze.

Umehluko izikhulumi

Noma yiluphi uhlelo acoustic siqukethe izikhulumi (MF, LF futhi RF), imishini gqwa, isiginali yokukhulisa umsindo, izintambo alalelwayo, futhi terminals input. amadivaysi Filtration banesibopho ukwehlukana isignali umsindo laba amaqoqo ambalwa. Acoustic-dual band isihlungi imvamisa ihlukane kabili "ingxenye" - izinkulungwane 5-6 Hz nangaphezulu 6 kHz .. Three amadivayisi ngokuvamile ifakwe crossovers - adjustable imvamisa ukuhlunga okuyinto ukwehlukana ububanzi umthamo izigaba ezintathu.

Zonke imishini acoustic kungaba nemphambosi yekwentiwa. Esimweni sokuqala ilawudispikha ngamunye ifakwe ahlukene isignali amplifier. Le isixazululo kusiza umgwaqo emitters, ukunciphisa jikelele izindleko ohlelweni. Nokho, nge yinkimbinkimbi okwandisa yesevisi, ukufakwa kanye ukucushwa sokuqala. yokukhulisa umsindo Hlukanisa ngokuvamile isethi ayahambelana ezintathu amadivayisi.

Coaxial kanye Uphiko Izikhulumi

Lokho ngeke kuzwakale kuyisibalo esikhulu izikhulumi amathathu- noma ezimbili emotweni lincike ohlotsheni izikhulumi ukuthi kukhona coaxial futhi ingxenye. Eyokuqala isakhiwo esisodwa Monolithic lapho radiators ehlangana phakeme, futhi imisindo ephansi. Le isixazululo sikwenza kuzwakale ohlangothini kakhulu. Ngakho-ke, ama-apharathasi enjalo isetshenziswa ibhekwa njengoba futhi okungcono izimoto ezincane. Izikhulumi Uphiko Uyi emitters, okuyinto zingahlelwa ezindaweni ezahlukene. Ngenxa yalesi kungenzeka ukufeza umsindo ozungezayo, Nokho, luyindida yokufaka. Futhi, ngenxa yokufaka engafanele umsindo esiteji kuyoba ngempela heterogeneous. Uphiko izinhlelo ukufakwa izimoto nge ingaphakathi ivulekile.

Intengo udaba

Njengoba kushiwo ngaphambili, ababili-indlela isikhulumi kuyoba ishibhile kuka kokufaka imishini emithathu band. Kunezizathu ezimbili:

• inani encane imishini - kudinga izipikha ezimbili kuphela, linanikhulu lema-yokukhulisa umsindo ezimbili futhi isihlungi esisodwa;
• ukufakwa elula - ukuqoqa isimiso esinjalo kungaba ngokuzimela, abanolwazi oluyisisekelo emkhakheni kagesi.

Ukwakheka kohlelo emithathu indlela kufaka imishini eyinkimbinkimbi, izindleko okuyinto kunalelo intengo amadivayisi ezivamile. Futhi, uma unquma ukufaka Izikhulumi ezifana, kuzodingeka ukuba bacele usizo ochwepheshe - kungekho amadivayisi wokulinganisa ekhethekile futhi mncane uhlelo indlebe-agibele amahhashi liyokhala kuyafana ezimbili ngendlela izikhulumi. Lona impendulo eyinhloko yombuzo umehluko phakathi ezimbili ngendlela izikhulumi ezintathu-indlela.
