Ndlela-ezintathu ndlela mbini izithethi: omsebenzi osemqoka, amathuba, umahluko

Kwimarike zanamhlanje izithethi yaziswe kuluhlu enkulu kangangoko. Le zixhobo yohlukile enye kwenye kumda (sixhobo, kwikonsathi, istudiyo, njl) ngokwenkcukacha kunye nefomu igobhogobho nezinye iimpawu ezininzi. Parameter ibalulekileyo ekufuneka kuqwalaselwa kwindawo yokuqala, inani 'imivalo' kule nkqubo. Ngokwale njengenqobo yokugweba, ezikhethekileyo olulodwa, emithathu ndlela mbini abantetho isisiXhosa. Njani kwahluka enye kwenye yaye inkqubo ungcono, siya kuzama ukuphendula kweli nqaku.

Njalo isandi

amalungu oLuntu ngeendlebe bayakwazi ukuqaphela izandi kumaza we-20 ukuya 20,000 Hz. Ngoko ke, umgangatho umculo kuxhomekeke ekukwazini izixhobo ukwenza amaza omsindo mnandi ngayo kumqolo onikiweyo. Ukulungiselela le njongo, xa isithethi yaqala ukuhlanganisa izithethi ukuba zande ephantsi kakhulu (20-150 Hz), eliphakathi (100-7000 Hz) kunye ophezulu (5-20 amawaka. Hz) ezitsho. Kulo mba, kwakukho:

1. inkqubo SSB, apho lonke uluhlu frequency yenza isithethi enye.
2. abathetha ndlela-mbini, nto leyo eye izithethi ezimbini: omnye ukudlala umculo kwi aphakathi ezitsho ephantsi, kwaye eyesibini - kuphela phezulu.
3. izixhobo-lane Three - lokudlala kwizandi kuluhlu ngalunye lihambisana "kwikholam" eyahlukileyo.

Kukho izixhobo a lot of bands, apho isithethi ngasinye iphinde izivelise kwakhona isandi ngendlela ethile uluhlu rhoqo. Ethandwa kakhulu ukuba inkqubo kwiikhosi zeeveki ezimbini ukuya lane amathathu - zezona nokufikelelekayo ngexesha elifanayo ukunika Obusemagqabini ubunjani sound.

Izinto eziluncedo ze abathetha endlela-mbini

abathetha ndlela-ezimbini ithandwa kakhulu phakathi abaqhubi beemoto. Zinika elilelona yomsindo ngexesha ezifanayo ixabiso elifanelekileyo. Ngenxa kuphuhliso indlela-mbini technology Acoustics ngenkuthalo zashiya izixhobo-band ezintathu, kodwa kusekho ixhaphake ngenxa zisiza;

1. Uyilo elula, leyo lula ufakelo kunye uqwalaselo.
2. Iqondo eliphezulu ukuvumelana phakathi izithethi, nto leyo kwizinga eliphezulu kunye nesandi.
3. Eyona zendalo, isandi "live".

Le izixhobo emzileni-amabili uye izithethi ezimbini kuphela - bass kunye treble. Bass isithethi uvelisa izandi kwi kolundi eliphantsi mid, kunye RF - Kuphela phezulu. Ngenxa oku kwinkqubo kufuneka uthungelwano crossover elula.

Features izixhobo-band ezintathu

isithethi ndlela-Ezintathu yahlukile ukusuka kwinkqubo sele ichaziwe sandi. Izixhobo kwiinkqubo ezifana doukomplektovyvaetsya umqhubi midrange, nto leyo ephethe ebizwa ngokuba yi-lwazi 'lwesithuba "yenza isandi akuyo. Ukongeza, ngenxa ukwahlulwa imisebenzi, izixhobo iye ezincinane. kwizinga okugwenxa iinkqubo-band ezintathu lixabiso phezulu. Kuyinto izihlandlo ezimbini ukuya kwezintathu ngaphezu koko labantu abathetha ndlela-mbini. Ngaphezu koko, indlela ezintathu-umsindo crossover ibandakanya ufakelo - ezintsonkothileyo amacebo rhoqo. Ukuba abathobekileyo abamise eso sixhobo kufuneka zetyala esemagqabini, okanye ukufikelela ukuvumelana le izithethi ziya kusebenza.

izithethi Umehluko

Nayiphi na inkqubo ive ibandakanya ezithethi (MF, LF kunye RF), izixhobo nokuyicoca, yokukhulisa umqondiso, iintambo odiyo, kwaye igalelo ezinjengeetheminali. izixhobo product banoxanduva ukwahlulwa uphawu evakalayo iimfuduka eziliqela. Acoustic elikabini yefrikhwensi lokucoca ihlukane ezimbini "isahlulo" - to 5-6 amawaka Hz nangaphezulu 6 kHz .. izixhobo ndlela-Ezintathu baxhotyisiwe jikelele kunye crossovers - amacebo asetyenziswa rhoqo adjustable leyo uwahlule uluhlu umthamo kathathu.

Zonke izixhobo ive angaba abakhuthele okanye kwisixando sokwenziwa. Kwimeko yokuqala lizwi nganye lixhotyiswe msindo uphawu eyahlukileyo. Le isisombululo lula ulungelelwaniso emitters, ukunciphisa iindleko inkqubo iyonke. Nangona kunjalo, kunye ubuxhakaxhaka inkonzo, ukufakela kunye Uqwalaselo lokuqala. yokukhulisa ezahlukeneyo badla iseti oluncedisanayo kwezixhobo ngendlela ezintathu.

Izithethi yafakwa iCandelo

Oko kuya kuvakala ngathi izithethi emithathu okanye indlela emibini imoto ixhomekeke kuhlobo ezithethi ukuba yafakwa kunye candelo. Eyokuqala isakhiwo esinye monolithic apho radiators zidibene aphezulu, aphakathi kunye ezitsho ephantsi. Le isisombululo yenza oko kuvakala zemiyalelo kakhulu. Ngoko ke, izixhobo ezifana isetyenziswa xa besitya kunye ekukhethwa iimoto ezincinci. Izithethi Component i emitters, apho kunokwenziwa amalungiselelo kwiindawo ezahlukeneyo. Ngenxa oku kunokwenzeka ukufezekisa isandi bayawarhawula, Noko ke, ngaba inkqubo yokufaka inzima. Kwakhona, ngenxa ufakelo ngokungafanelekanga lwe sigaba isandi iya kuba yinto owahlukeneyo. iinkqubo Component efakwe kwi iimoto kunye ingaphakathi eliphangaleleyo.

Ixabiso udaba

Njengoko kukhankanyiwe ngaphambili, isithethi ndlela-mbini iya kuba sitshiphu kunokuba kufakwa izixhobo-band ezintathu. Kukho izizathu ezibini:

• imali encinci yezixhobo - kufuna izithethi ezimbini kuphela, ezona yokukhulisa amabini kunye filter nye;
• ufakelo elula - ukuqokelela inkqubo enjalo kunokuba ngokuzimeleyo, ukuba nolwazi olusisiseko entsimini kombane.

Ukwakhiwa kwenkqubo ngendlela ezintathu-kuquka izixhobo nobunzima kakhulu, iindleko zeziphi iphezulu kakhulu ixabiso izixhobo eziqhelekileyo. Kwakhona, xa usenza isigqibo sokuba ufake abathetha olo lwimi, uya kufuneka ufune uncedo iingcali - kungekho izixhobo ezikhethekileyo kunye nenkqubo indlebe-enyusiweyo ezingcakacileyo, nibethe efanayo njengoko izithethi endlela-mbini. Le impendulo engundoqo umbuzo umahluko phakathi bathetha ngendlela ezimbini ukusuka kwindlela ezintathu.
