1. Intangiriro ku bavuga rikijyana

Indangururamajwi yerekeza ku gikoresho gishobora guhindura amajwi mo amajwi. Mu magambo asanzwe, yerekeza ku cyuma gitanga ingufu cyubatswe mu kabati k'indangururamajwi cyangwa mu kabati ka subwoofer. Iyo ikimenyetso cy'amajwi cyongerewe kandi kigatunganywa, indangururamajwi ubwayo iracurangira kugira ngo ijwi rirusheho kumvikana. Irushaho kuba nini.

Indangururamajwi ni yo shingiro ry'urusaku rwose. Inshingano yarwo ni uguhindura ingufu z'amajwi mo ingufu z'amajwi zijyanye no kuyashyira mu mwanya. Ni igice cy'ingenzi cyane cy'urusaku kandi gifite inshingano zo guhindura ibimenyetso by'amashanyarazi mo ibimenyetso by'amajwi ku bantu. Inshingano yo kumva amatwi neza.

Imiterere y'umuvugizi:

Indangururamajwi ziri ku isoko ziza mu buryo n'amabara yose, ariko uko zaba ziri kose, zigizwe n'ibice bibiri by'ibanze:umuvugiziicyuma (cyitwa Yangsheng unit) n'akabati. Byongeye kandi, indangururamajwi nyinshi zikoresha nibura ebyiri cyangwa ebyiri. Izindi ndangururamajwi zavuzwe haruguru ni zo zishyira mu bikorwa icyo bita multi-channel sound reproduction, bityo crossover nayo ni igice cy'ingenzi. Birumvikana ko hashobora kubaho ipamba ifata amajwi, imiyoboro ihinduriwe inyuma, "imiyoboro ya labyrinth" ipfunyitse, n'indangururamajwi zikomeye. Imbaho ​​/ imbaho ​​zo gukingira amajwi zikomeye n'ibindi bice, ariko ibi bice si ngombwa ku ndangururamajwi iyo ari yo yose. Ibice by'ibanze by'indangururamajwi ni ibice bitatu gusa: icyuma cy'indangururamajwi, akabati n'igice cy'indangururamajwi.

Ishyirwa mu byiciro ry'abavuga:

Ishyirwa mu byiciro ry'indangururamajwi rifite inguni n'ibipimo bitandukanye. Dukurikije imiterere y'indangururamajwi, hari udusanduku tudahumeka, udusanduku tw'amajwi (tuzwi kandi ko ari udusanduku tw'amajwi make), indangururamajwi za radiator zitarimo amajwi, n'indangururamajwi zo mu murongo w'itumanaho. Agasanduku k'inverter ni ko gakoreshwa cyane ku isoko ry'ubu; ukurikije ingano n'aho indangururamajwi ziherereye, hari udusanduku tw'amajwi duhagaze hasi n'udusanduku tw'ibitabo. Ubwa mbere bunini kandi bukunze gushyirwa hasi. Hari igihe ibirenge bito bitera ubwoba bishyirwa munsi y'indangururamajwi. Bitewe n'ingano nini y'akabati n'uburyo bworoshye bwo gukoresha amajwi manini kandi menshi, agasanduku ko hasi kugeza ku gisenge gakunze kugira frequency nto, urwego rw'umuvuduko w'amajwi menshi n'ubushobozi bukomeye bwo gutwara, bityo kaba gakwiriye ahantu hanini ho kumva cyangwa ibisabwa byose. Agasanduku k'amajwi ni gato kandi gakunze gushyirwa kuri tripod. Karangwa no gushyiramo ibintu byoroshye kandi ntigafata umwanya. Ariko, bitewe n'ingano y'agasanduku n'umurambararo w'umurambararo n'umubare w'ama-woofers, frequency yako nto ikunze kuba iri hasi ugereranyije n'iya gasanduku ko hasi, kandi imbaraga zayo zo gutwara. Kandi urwego rw'umuvuduko w'amajwi narwo ni ruto, rukwiriye gukoreshwa mu buryo buke bwo kumva; hakurikijwe bandwidth ntoya yo gucuranga, hari indangururamajwi za interineti na indangururamajwi za narrowband. Indangururamajwi nyinshi zagenewe gutwikira. Umurongo wa frequency mugari ushoboka ni indangururamajwi za bande nini. Ubwoko bukunze gukoreshwa cyane bwa ndangururamajwi za narrowband ni subwoofer (subwoofer) yavuye muri home theatre, ikoreshwa gusa mu gusubiza frequency yo hasi cyane ku murongo wa frequency muto cyane; bitewe niba hari amplifier y'amashanyarazi yubatswemo, ishobora kugabanywamo indangururamajwi za passive na Active speakers, iya mbere ntabwo ifite amplifier yubatswemo kandi iya nyuma ifite. Kuri ubu, indangururamajwi nyinshi zo mu rugo ni passive, ariko subwoofers akenshi ni active.

2. Intangiriro y'Amajwi

Amajwi yerekeza ku majwi atari ururimi rw'abantu n'umuziki, harimo amajwi y'ibidukikije karemano, amajwi y'inyamaswa, amajwi y'imashini n'ibikoresho, n'amajwi atandukanye akorwa n'ibikorwa by'abantu. Amajwi ashobora kuba arimo amplifier y'imbaraga, ibikoresho byo ku ruhande (harimo compressor, effector, equalizer, VCD, DVD, nibindi), indangururamajwi (indangururamajwi, indangururamajwi), mixer, mikoro, ibikoresho byo kwerekana, nibindi. Muri byo, indangururamajwi harimo ibikoresho bisohora amajwi, indangururamajwi, subwoofer, nibindi. Indangururamajwi irimo indangururamajwi eshatu, zo hejuru, zo hasi, n'iziciriritse, eshatu ariko si ngombwa ko ari eshatu. Amateka y'iterambere ry'ikoranabuhanga ashobora kugabanywamo ibice bine: imiyoboro ya elegitoroniki, transistors, imiyoboro ihuriweho, na transistors z'ingaruka z'umurima.

Ibice by'amajwi:

Ibikoresho by'amajwi bishobora kuba birimo amplifiers z'amashanyarazi, ibikoresho byo mu gice cyo hejuru (harimo compressors, effets, equalizers, exciters, nibindi), indangururamajwi (indangururamajwi, indangururamajwi), mixers, amasoko y'amajwi (nka mikoro, ibikoresho bya muzika, VCD, DVD) ibikoresho byo kwerekana N'ibindi, shyira hamwe kugeza kuri seti imwe. Muri zo, indangururamajwi harimo ibikoresho bisohora amajwi, indangururamajwi, subwoofers, nibindi. Indangururamajwi irimo ubwoko butatu bw'indangururamajwi, hejuru, hasi, n'ubuciriritse, ariko si ngombwa ko ari eshatu.
