1. Isingeniso kuzikhulumi

Isipikha sisho idivayisi engaguqula amasignali omsindo abe umsindo.Ngokwemigomo ye-layman, isho isikhulisi samandla esakhelwe ngaphakathi kukhabhinethi yesipikha esikhulu noma ikhabhinethi ye-subwoofer.Ngemva kokuba isignali yomsindo ikhulisiwe futhi yacutshungulwa, isipikha ngokwaso sidlala umsindo ukuze siwenze umsindo.Khula.

Isipika siyitheminali yalo lonke uhlelo lomsindo.Umsebenzi wawo ukuguqula amandla omsindo abe amandla omsindo ahambisanayo futhi akhanyise endaweni.Iyingxenye ebaluleke kakhulu yesistimu yomsindo futhi inomthwalo wemfanelo wokuguqula amasignali kagesi abe amasignali e-acoustic kubantu.Umsebenzi wokulalela ngqo ezindlebeni.

Ukwakheka kwesipika:

Izikhulumi emakethe ziza ngazo zonke izinhlobo nemibala, kodwa kungakhathaliseki ukuthi iyiphi, zakhiwe izingxenye ezimbili eziyisisekelo:isikhulumiiyunithi (ebizwa ngokuthi i-Yangsheng unit) kanye nekhabhinethi.Ngaphezu kwalokho, izikhulumi eziningi zisebenzisa okungenani ezimbili noma ezimbili Amayunithi ezipikha angenhla kuphela asebenzisa lokho okubizwa ngokuthi ukukhiqizwa komsindo weziteshi eziningi, ngakho-ke i-crossover nayo iyingxenye ebaluleke kakhulu.Kunjalo, kungase kube khona ukotini omunca umsindo, amashubhu ahlanekezelwe, “amapayipi e-labyrinth” agoqiwe, nezipikha eziqinisiwe.Izimbambo/amabhodi okufaka umsindo aqinisiwe nezinye izingxenye, kodwa lezi zingxenye azibalulekile kunoma yisiphi isipikha.Izingxenye eziyisisekelo kakhulu zesipika ziyizingxenye ezintathu kuphela: iyunithi yesipika, iKhabhinethi kanye ne-crossover.

Ukuhlukaniswa kwezikhulumi:

Ukuhlukaniswa kwezikhulumi kunama-engeli namazinga ahlukene.Ngokwesakhiwo se-acoustic sezipikha, kukhona amabhokisi angangeni moya, amabhokisi ahlanekezelwe (aphinde abizwe ngokuthi amabhokisi e-low frequency reflection box), izipikha zerediyetha ezingenzi lutho, nezipikha zolayini wokudlulisa.Ibhokisi le-inverter yilona elihamba phambili emakethe yamanje;ngokombono wesayizi nokubekwa kwezikhulumi, kukhona amabhokisi ami phansi kanye namabhokisi eshelufu lezincwadi.Eyangaphambili inkulu ngokuqhathaniswa ngosayizi futhi ivamise ukubekwa ngqo phansi.Kwesinye isikhathi, izinyawo ezibamba ukushaqeka nazo zifakwa ngaphansi kwezipikha..Ngenxa yomthamo omkhulu wekhabhinethi kanye nokuba lula kokusebenzisa ama-woofer amakhulu nangaphezulu, ibhokisi elisuka phansi kuya ophahleni livamise ukuba namafrikhwensi angcono aphansi, izinga lokucindezela komsindo okukhiphayo eliphakeme namandla okuthwala anamandla, ngakho lifanelekela izindawo ezinkulu zokulalela. noma izidingo ezibanzi kakhulu Ibhokisi leshalofu lezincwadi lincane ngosayizi futhi livamise ukubekwa ku-tripod.Ibonakala ngokubeka okuguquguqukayo futhi ayithathi isikhala.Kodwa-ke, ngenxa yomthamo webhokisi kanye nomkhawulo we-diameter kanye nenombolo ye-woofers, imvamisa yayo ephansi ngokuvamile iphansi kunebhokisi eliphansi, namandla ayo okuthwala Futhi izinga lokucindezela komsindo okukhiphayo nalo lincane, elifanelekile. ukusetshenziswa endaweni encane yokulalela;ngokuya ngomkhawulokudonsa omncane wokudlala, kukhona izipikha ze-broadband nezipikha ze-narrowband.Izipikha eziningi ziklanyelwe ukumboza Ibhendi yefrikhwensi ngobubanzi ngangokunokwenzeka yisipika esinebhendi ebanzi.Uhlobo oluvame kakhulu lwezipikha ze-narrow-band i-subwoofer (i-subwoofer) eyavela nethiyetha yasekhaya, esetshenziselwa kuphela ukubuyisela i-ultra-low frequency ibe ibhendi yefrikhwensi encane kakhulu;ngokuya ngokuthi sikhona yini isikhulisi samandla esakhelwe ngaphakathi, singahlukaniswa ngezipikha ezingenzi lutho kanye nezipikha ezisebenzayo, esokuqala asinaso i-amplifier eyakhelwe ngaphakathi kanti lesi sakamuva sinaso.Njengamanje, izipikha eziningi zasekhaya azisebenzi, kodwa ama-subwoofers ngokuvamile ayasebenza.

2. Isingeniso Somsindo

Umsindo usho imisindo ngaphandle kolimi lwabantu nomculo, okuhlanganisa imisindo yendawo yemvelo, imisindo yezilwane, imisindo yemishini namathuluzi, nemisindo eyahlukene eyenziwa izenzo zomuntu.Umsindo cishe uhlanganisa isikhulisi samandla, okokusebenza okuzungezile (okuhlanganisa i-compressor, i-effector, isilinganisi, i-VCD, i-DVD, njll.), izipikha (izipikha, izipikha), i-mixer, imakrofoni, okokusebenza kokubonisa, njll. engeza kufikela kusethi.Phakathi kwazo, izikhulumi ziyimishini yokukhipha umsindo, izikhulumi, ama-subwoofers, njalonjalo.Isipika sihlanganisa izikhulisa-zwi ezintathu, eziphezulu, eziphansi, neziphakathi, ezintathu kodwa hhayi ngempela ezintathu.Umlando wokuthuthukiswa kobuchwepheshe ungahlukaniswa ngezigaba ezine: amashubhu e-electron, ama-transistors, ama-circuits ahlanganisiwe, nama-transistors omphumela wensimu.

Izingxenye zomsindo:

Imishini yomsindo cishe ihlanganisa izikhulisamandla, okokusebenza okuseceleni (okuhlanganisa ama-compressor, imiphumela, izilinganisi, ama-exciters, njll.), izipikha (izipikha, izipikha), izixube, imithombo yomsindo (njengemibhobho, izinsimbi zomculo, i-VCD, i-DVD) imishini yokubonisa Kanjalo on, engeza kufikela kusethi eyodwa.Phakathi kwazo, izipikha kukhona imishini yokukhipha umsindo, izipikha, ama-subwoofers, njll. Isipikha sihlanganisa izinhlobo ezintathu zezipikha, eziphezulu, eziphansi, nezimaphakathi, kodwa hhayi ezintathu.
