1. Isingeniso sezikhulumi

USomlomo ubhekisa kudivayisi engaguqula amasiginali alalelwayo abe msindo. Ngemigomo ye-Lambeman, kubhekisa ku-Amplifier eyakhelwe ngaphakathi yekhabethe eliyisikhulumi esikhulu noma ikhabethe elingaphansi komhlaba. Ngemuva kokuthi isiginali yomsindo sikhulisiwe futhi sacutshungulwa, isikhulumi uqobo sibuyisa umsindo ukuwenza uzwakale. Khulisa.

Isipika siyisiginali salo lonke uhlelo lomsindo. Umsebenzi wayo ukuguqula amandla alalelwayo ukuba abe namandla ahambisanayo womsindo bese ukhanyisa esikhaleni. Kuyingxenye ebaluleke kakhulu yohlelo lomsindo futhi unesibopho sokuguqula amasiginali kagesi abe yizimpawu ezi-acoustic zabantu. Umsebenzi wokulalela ngqo ezindlebeni.

Ukwakheka kwesipika:

Izikhulumi emakethe ziza kuzo zonke izinhlobo nemibala, kepha noma ngabe yimuphi, bakhiwa izingxenye ezimbili eziyisisekelo:isikhulumisiiyunithi (elibizwa nge-yangsheng unit) kanye nekhabethe. Ngaphezu kwalokho, izikhulumi eziningi zisebenzisa okungenani okungenani ezimbili noma ezimbili kuphela ezingenhla kwezipikha ezisebenzisa ukukhiqizwa komsindo okuthiwa yi-Multi-Channel, ngakho-ke i-crossover nayo iyingxenye ebaluleke kakhulu. Kuyiqiniso, kungahle kube nokuba nekotini edonsa kahle, amashubhu angenanqwaba, amapayipi asongelwe "agoqiwe", nezikhulumi eziqinisiwe. Izimbambo / izimbambo eziqinisiwe zokufakwa komsindo nezinye izinto, kepha lezi zinto azibalulekile kunoma yisiphi isipika. Izakhi eziyisisekelo kunazo zonke zesipika ziyizingxenye ezintathu kuphela: uphiko loSpikha, iKhabhinethi neCrossover.

Ukuhlukaniswa kwezikhulumi:

Ukuhlukaniswa kwezikhulumi kune-engeli namazinga ahlukile. Ngokwesakhiwo se-acoustic of the izikhulumi, kunamabhokisi e-airtight, amabhokisi angenazinkinga (abizwa nangokuthi amabhokisi okubonisa ama-radiator aphansi), izipikha ze-radiator zokudlulisa, kanye nezikhulumi zokuhambisa. Ibhokisi le-Inverter liyinto ejwayelekile yemakethe yamanje; Ngokombono wosayizi nokubekwa kwezikhulumi, kukhona amabhokisi angemuva amabhokisi namabhokisi okubhuka. Owangaphambili usayizi omkhulu ngosayizi futhi uvame ukubekwa ngqo emhlabathini. Kwesinye isikhathi, izinyawo ezikhushulwa ukuthuthumela nazo zifakwa ngaphansi kwezikhulumi. . Ngenxa yevolumu enkulu yekhabethe kanye nokusebenziseka kalula kokusebenzisa ama-woofers amakhulu futhi aphezulu, okuphezulu kophahla kuvame ukuba nezindawo eziphansi zokulalela noma ilungele izidingo ezinamandla zokulalela noma i-abhula amabhokisi ezincwadi zincane ngosayizi futhi zivame ukubekwa ku-tripod. Kubonakaliswa ukubekwa okuguqukayo futhi akuhlali isikhala. Kodwa-ke, ngenxa yevolumu yebhokisi kanye nomkhawulo wobubanzi nenombolo yama-woofers, imvamisa yalo ephansi kuvame ukwehlisa ukwedlula lokho kwebhokisi eliphansi, futhi elithi izinga lokucindezela imisindo lemisindo lincane, elilungele ukusetshenziswa endaweni encane yokulalela; Ngokusho kwe-bandwidth emincane yokudlala, kunezikhulumi ezibanzi nezikhulumi ezincanyana. Izikhulumi eziningi zenzelwe ukumboza ibhendi yemvamisa ebanzi ngangokunokwenzeka iyisipika se-band ebanzi. Uhlobo olujwayelekile kakhulu lwezikhulumi ze-bandis-band yi-subwoofer (subwoofer) evele nethiyetha yaseshashalazini yasekhaya, esetshenziselwa kuphela ukubuyisa imvamisa ephansi ye-Ultra ku-Frequency band kakhulu; Ngokusho kokuthi kukhona i-amplifier eyakhelwe ngaphakathi, ingahlukaniswa izikhulumi eziphawula izikhulumi nezikhulumi ezisebenzayo, ingabe yangaphambili ayinayo i-amplifier eyakhelwe ngaphakathi kanye nalokhu okulandelayo. Njengamanje, izikhulumi eziningi zasekhaya zinezinto ezimbalwa, kepha ama-subwoofers ajwayele ukusebenza.

2. Isingeniso somsindo

Umsindo ubhekisa kumisindo ngaphandle kolimi lwabantu nomculo, kufaka phakathi imisindo yemvelo yemvelo, imisindo yezilwane, imisindo yemishini namathuluzi, nemisindo ehlukahlukene eyenziwe ngezenzo zabantu. Umsindo mhlawumbe ufaka i-amplifier yamandla, imishini yokuhlanza (kufaka phakathi i-compressor, i-applear, i-autizer, i-dvd, i-DVD, i-microphone, iminyombo, imishini yokubonisa, njll. Faka imishini yokubonisa, njll. Faka isethi. Phakathi kwazo, izikhulumi zingamadivayisi okukhipha umsindo, izikhulumi, ama-subboofers nokunye. Isikhulumi sifaka phakathi amazwi aphezulu, aphezulu, aphansi, futhi aphakathi, amathathu kodwa hhayi amathathu. Umlando we-Development of Technology angahlukaniswa izigaba ezine: amashubhu we-elektroni, ama-transistors, amasekethe ahlanganisiwe, kanye ne-Field Effect Trafistors.

Izingxenye zomsindo:

Imishini yokulalelwayo kungenzeka ifaka ama-amplifiers wamandla, imishini ye-peripheral (kufaka phakathi ama-compressors, imiphumela, izipikha, izingoma zomculo (amathuluzi omculo, angezele kusethi eyodwa. Phakathi kwazo, izikhulumi zingamadivayisi okukhipha umsindo, izikhulumi, ama-subboofers, njll. Isikhulumi sifaka izinhlobo ezintathu zezikhulumi, eziphakeme, eziphansi neziphakathi, kepha azinazo ezintathu.
