Umsindo Umgangatho: Ukucacisa kunye neemodeli

umsindo Umgangatho namhlanje - sisalathisi nje kuphela kakuhle-ntle zemali, kodwa uphawu obucacileyo yokuqonda kubuchwepheshe kunye nokufumaneka incasa elungileyo. market Umculo minyaka yonke inika imodeli entsha ukuphucula ngakumbi nangakumbi, aze afumane into ezifanelekileyo maxa wambi kunzima kakhulu ukuba wena.

Kakade ke, uyakwazi ukuphulaphula umculo owuthandayo ingasetyenziswa yaye "zikaJ tatomkhulu", kodwa akubonakali wosondeza umthamo kunye nokucaca kwiplanga elimcambalala isandi, onako ukuze adlulisele izithethi ezikumgangatho ophezulu. Zeziphi iinkqubo ilungele ekhaya, yaye ngenxa imoto?

Njani ukuba kwaqala

Izixhobo lokuqala ushicilelo nokukotshwa bubonakala kwenkulungwane ye-19. Abazange ukusebenza umbane kunye zoomatshini. Umzekelo iphawulekayo woku igramafoni Edison (1877), owabhala isandi kunye intshukumo ngenaliti, ebandakanya inwebu. Motion kwenzeka igubu, amafutha camera okanye ngefoyile. Ngoko inaliti isusiwe endleleni sele iyelenqe. Ngoko ke umsindo.

Endaweni umdlali irekhodi igramafoni weza. Umgaqo ukusebenza ihlala efanayo, kuphela endaweni kwigubu kusetyenziswa dial lacquered. Gramophones, iigramafoni koko ngokuthe saa kwihlabathi jikelele.

ukuphumelela

Umba lokusetyenziswa umbane isandi ukuzala kwavuleka. Emva ngo 1824 Ernst Siemens (umdali bumabumela eponymous) Inkcazelo isixhobo, apho coil okhethekileyo kwenyukwa ehamba phantsi kwempembelelo umsinga wombane, kunye intlokoma zayo ukuvelisa isandi. Noko ke, wayila wahlala kwithiyori de 1915. Nangona olu phuhliso azithathelwanga phezulu iinjineli kwi Bell (Umsunguli ngomnxeba). Kungekudala, izitalato ezihonjiswe uphondo imibhobho. Kodwa ke uluhlu baye belufudula luphantsi kakhulu.

Le impumelelo yokwenene umsindo baba radiator electrodynamic evela kwinkampani American "Electric General". It uvalo ezisebenza kuluhlu kakhulu ngentla frequency yayo. Izixhobo esetyenziselwa kwemibhobho Radiola Model 104 sithumela Radiola 28. Ngo-1927 umgangatho godu isandi iphucuke ukuqaliswa intloko kuyilo lokuhlaba umazibuthe esisigxina. Ukususela ngelo xesha, ukuba kwakukuninzi utshintsho ukusuka izithethi, kodwa isimiso ukusebenza uhlala okufanayo.

emitter

inkqubo ive Modern ezilungiselelwe ukudlala audio kwaye ziqulathe loyilo ive kunye isithethi oluhlangeneyo. Ngokutsho nenani lezithethi bahlule phakathi olunye-band kunye nezixhobo multiband. Yenza emitter iphinde izivelise kwakhona ngokucacileyo izandi ezitsho ezahlukeneyo, kunzima, ngoko hayi inkqubo-band twa.

Kwizixhobo multiband, imisindo zahlulwe bands eziliqela ayangenana. intloko yayo ngentshukumo yenzelwe band nganye. Kuyinto sixhobo kungenxa izithethi ezikumgangatho ophezulu.

izithethi Classification

Zonke izithethi zahlulwe zibe esebenzayo neyokwenziwa (ukuba uqhagamshelwano ngombhobho), kwithala kunye kumgangatho (ubukhulu), ngendleko ephantsi, Hi-Fi, High-Isiphelo-class (ngexabiso).

Le fowuni iquka sonar transducer eyimpumelelo crossover, msindo yangaphandle. Esongezelelwe esebenzayo msindo ngamandla lwangaphakathi. sesimangalo eyakhelwe-ngaphakathi konga imali ngenxa yokuba akukho mfuneko yokuthenga i ufakelo olongezelelweyo. Noko ke, ukuba inkqubo isithethi efakwe kwi phezulu ngokwaneleyo, ukugcinwa msindo nzima. Iinkqubo ezinamandla yokukhulisa Acoustic ezifakwe kwiyunithi nganye, kwaye ke ifuna izinto ezimbini ngamandla. Ngako oko, le nokunyuka kwamaxabiso kunye nefowuni.

Kuthathelwa ingqalelo zonke ubuqili ukusetyenziswa nangengcinga esebenzayo ive iinkqubo ezifanelekileyo neekhompyutha zobuqu, kunye nokuhlolwa studio nokuveza disco kunye neendawo ezincinane.

Xa uhlobo eyahlukileyo zonke-imozulu umsindo system. Basebenza kwiimeko ezinzima, kunye notshintsho lobushushu ngokukhawuleza. Njengoko kwakunye neenkqubo yokuphila-iklasi ezidibanisa uyilo olupheleleyo kunye nesandi esemgangathweni.

design ive

Ukwenza imibhobho zimelwe embodiments eziliqela. Kusenokwenzeka ukuba zivaliwe okanye ibhokisi evulekileyo. Le yokugqibela ziquka screens yiacoustic okanye amakhaka, ngokunjalo ekuthiwa "umzimba olusebenzayo". Mhlawumbi zavunyelwa Jensen-Onken, umemelele, kwaye Push-kume, kunye nenkqubo ekulo. Ukongeza, iya kusetyenziswa "lensi ive" okanye resonator Helmholtz.

ezibonakalayo

Ukukhetha yesithethi, ukongeza iimpawu zobugcisa kubalulekile yaye umbandela ifowuni eyenziwe kuzo. Kuba oko kuchaphazela umgangatho isandi kunye neendleko nkqubo. imiqolo Corpus akholisa eyenziwe ngomthi, iplastiki kunye nentsimbi. Ngamanye amazwi, i "umzimba" wentsika kufuneka ibe ngqongqo ukufunxa / ukubonakalisa amaza isandi amandla athile, rhoqo.

yeplastiki esetyenzisiweyo ngokukhethwa mali. Columns lweemo ezahlukeneyo kakhulu kunokwenzeka, kaninzi zisetyenziselwa neekhompyutha zobuqu. Noko ke, elinye ethile ngeplastiki. Yena rattles off esikhulu xi isandi (unyuse ivolyum). Nangona kukho imifuziselo ezithethi, umzimba yayo eyenziwe ngeplastiki elaminethiweyo, ukumelana ngakumbi isandi amandla eliphezulu.

Olwenziwe Lula, ingxinano elungileyo, nobulukhuni babe casings ezibengezelayo izithethi, ingakumbi, zenziwe aluminiyamu. Aluminium ngokwayo kunciphisa livakale yaye kuphucula ukudluliselwa umsindo. Igcwala "metal ezililize" ukukhusela ezingenambala umboniso okhethekileyo. izixhobo ezinjalo zingasetyenziswa njenge-sezulu yonke.

Kodwa ke umsindo umgangatho unalo igobhogobho ngamaplanga. Ngokusesikweni, khetha umthi phambi ukusika, ngoko ukuma ixesha de lome ngokwendalo. imveliso engeyomfuneko processing ithathe indawo phantse yonke ngesandla. Le nto akusoloko ayifumaneki, ngoko wayedla ngamaplanga, MDF, ibhodi yamasuntswana. Le izinto uneempawu ezibalaseleyo ungawuthwali izandi ezincinane afunxa intlokoma isandi, abe ngqongqo ngomatshini, njl Le inyanda nokuthintela ukufuma Absorption umbala okanye buKristu khazi.

Ezinye abavelisi basebenzisa izixhobo ezingekho semgangathweni. Umzekelo, inkampani Ingxangxasi idala imiqolo lwezindlu kweglasi.

AU Housing

Ukukhetha isithethi inkqubo Unokucela ukuba wobuthongo nganye. Kwaye akukho nkqu umgangatho nexabiso, kwaye ezahlukeneyo labavelisi kunye neemodeli. umsindo Umgangatho kuba indlu ekhethiweyo yi algorithm kulandelayo:

• Ukuze uqalise kukuba isigqibo sokuba imbonakalo kunye nobukhulu nkqubo kufuneka ezinezipikha. Imbonakalo ixhomekeke kukhetho lobuqu kwaye ubungakanani kufuneka athobele igumbi apho aya khona icebo.
• Bekhumbula ubungakanani isithethi kufuneka ithathelwe ingqalelo kunye neempawu ive bezindlu kunye isithethi. Ngamanye amaxesha Iinkqubo naphakathi zinamandla kakhulu, loo nto ifanele igumbi elincinane.
• umsindo, eyona nto igobhogobho ngomthi, kodwa kufuneka anikwe ithuba kunye nezinye izinto. iimpawu zabo kwakhona "ityetyiswe" isandi.
• Ixabiso kwaye sheet data zobugcisa. Le ichaza iimpawu ezibalulekileyo: ubuntununtunu isandisi-lizwi (kuhle ukusuka 90 dB), uluhlu kwamaza (20 Hz-20 kHz), inani bands (amabini okanye amathathu), umlo AC (4,6-8 Ohm) kunye namandla ombane (Housing 50-100 W).
• Okokugqibela, khangela inkqubo ekhethiweyo. Kulo mzekelo, lo mshini kufuneka iseti multi-band, kunye ulawulo ithoni. Ngamanye amaxesha abacebisi intengiso unamaqhinga ekusetyenzisweni lo mshini.
• Kubalulekile nomculo ukwenzela ukudlulisa ezikumgangatho ophezulu. umthombo yesandi emele CD / DVD-player kunye drive brand (CD-format). umculo kwizinga ukuhlola umsindo isandi kakuhle ngokufanayo kumanqanaba umthamo ahlukeneyo.

AS iimoto

umsindo Umgangatho emotweni - umba akukho akanandaba. Abavelisi kunye ebhengeza kakhulu, kodwa ukuba ukhethe indlela enye ilungile? Kakade ke, ilungelo lokuxhomekeka ekhuhlangubeni lakho lomculo: sound amandla endalo okanye ukongamela kwalowo bass. Kodwa kukho iparameters alukhuni.

• Iyafuna ukunikela ingqalelo amandla. Kukhethwa, irabha kunokuba ilaphu ngeso lenyama.
• Ukufakwa. nezihlalo eziphambili ive kwisithuthi ziyaxhonywa exutywe ne Shchelkova pill (tweeters). Zinika soft, isandi egudileyo. Unobangela ndlwana Wobubhekisa izithethi (17-20 cm). Izithethi ngaphambili ziyazala ezitsho eziphakamileyo neziphakathi, ngasemva - ezitsho eliphantsi.
• USomlomo kufuneka iqonga, naphezu ucango - shumoizolyatory.
• indawo yokugqibela - umculo umgangatho ukuvavanya umsindo. isantya sebhithi ephakamileyo CD-format. Ngoko ke, oko Kukhethwa ukuba livavanye le nkqubo. I-MP3 kunye MPEG iifomati ukusetyenziswa ucinezelo, ngenxa yoko, umgangatho ilahlekile.

malunga nabenzi

Phakathi iinkampani inxaxheba ekudalweni iinkqubo yiacoustic, kukho ukholo ezininzi ezilungileyo kunye nexesha likho. Yamaha, Microlab, Cabasse, JMLab, Piega. Ingabinani German Bell-Audio iyaziwa ukusebenzisa umaleko-ezimbini ngakumbi ekwenziweni casings. Lexinene nekuba ukuba udada imithi. Enye top-inotshi nomvelisi AC yi Gemme Audio. Ngokuba models isebenzisa DSP kunye radiators ezinamandla.

izithethi imoto Umgangatho iveliswayo: Focal, Infinity, elilodwa, Morel, Magnat, kwakunye "izikhanyiso ezikhanyisayo» iteknoloji Panasonic, Pioneer, Kenwood.

Yenza kube ngokwakho

Ukuba iinketho ixabiso eliphantsi hayi anelisekile umgangatho, kwaye izithethi eninzi awuna mali yaneleyo, unako ukuzama ukuphuhlisa nokwakha inkqubo ngokwakho. Indlela yokwenza izithethi ezikumgangatho ophezulu?

Kakhulu nzima. Oku kufuna ixesha kuphela kwaye savvy, kodwa ulwazi iinkqubo ezithile. Ngokomzekelo, xa ukubalwa yoyilo yiacoustic, ukuma izithethi kwiqela lenjongo ngaphambili indibaniselwano zawo kwindlela ezimbini, ngendlela ezintathu. Kuba nokuveliswa bomhlathi ingathatha iinyanga.
