Subwoofer futhi uhlelo isikhulumi imvamisa impendulo

Ngasekuqaleni ngeminyaka yoma futhi Eighties kwekhulu elidlule, kukholakala ukuthi izikhulumi emikhulu kukholamu, ngcono. Izinto zesimanje yokusondela inhlangano sonification ka accomodations kancane ukusatshalaliswa ezahlukene Dolby Kaka uhlelo nge subwoofer ahlukene ukuzethemba kancane unyakaza elilungile isikhulumi umsindo ngezipikha amaningi, kodwa abalandeli Ushiye impela eningi.

Umbuzo ka yini okufanele Dynamics isikhulumi, obakhathalelayo abathuthukisi kanye bocwepheshe esikhathini lapho transducers electromechanical angena empilweni. Kukhona ukungqubuzana ethile e izidingo diffuser. Ngakolunye uhlangothi, ukuba aphansi ukudlalwa okunekhwalithi, uhla bass kufanele ibe nkulu ngokwanele futhi omkhulu ikhoyili kazibuthe, kwi "bass wahosha" eshiya iningi amandla. Ngakolunye uhlangothi, amaza okusezingeni eliphezulu adinga esiphezulu nje ngisahlose oscillatory uhlelo kanye inertia ubuncane.

Ekugcineni, onjiniyela izesekeli acoustic sebefike isixazululo okunengqondo kukholamu isebangeni woofers ndawonye ukusebenza nalokho okubizwa ngokuthi "tweeter". Nokho, kulesi simo-ke kwakha "ukwehluleka" phakathi bohlu, kodwa le nkinga siqedwa ngokwengeza isikhulumi sesithathu ukusebenza kuleli banga.

ngaleyo ndlela Frequency impendulo kuqondaniswe kuyo yonke band ezwakalayo. I woofer kungenziwa eziqhutshwa ngaphandle kwezihlungi ezengeziwe, kodwa ukuze kuncishiswe umthwalo ke nokulondoloza ukuqina, unikezwa inductance uchungechunge axhunywe kuqala, hhayi naphakathi transmissive namagagasi aphakeme. Ilawudispikha esiphakathi nokwazi ekutheni "waffle" kuya bass, kanye engenhla izingxenye isignali. Kuze kube yimanje, ngokuvumelana ifake ikhoyili futhi capacitor. Ngokuqondene 'tweeter ", khona-ke kwangathi lunikezwe khona okuhloswe kuphela sayo ukusuka band cishe 3 kHz nangaphezulu, kulolu ilawudispikha ochungechungeni nale capacitance ifakiwe.

Modern bass isipikha idivayisi eziyinkimbinkimbi electromechanical. Inkambo we diffuser mikhulu. Ukuhlinzeka ke isikhathi eside, izinto kudingeka ukumelana ukusonteka nokunwebeka futhi ngaleyo ndlela ukugcina izakhiwo zalo. Ngokuvamile, emitter onqenqemeni ehlangene indandatho iraba diffuzoroderzhatelem kwesigaba ongaphambili omise.

Stroke of a kwangu ambalwa, kufanele ibe indlela ekhanyako, kungenjalo emaphethelweni ikhoyili kuyoba "kubhalwa phezu kwayo" uzibuthe emaphakathi. Wanikeza washer ngokugxilisa ngokuvamile eyenziwe yokuhlanganisa resin elifakwe Indwangu perforated nge corrugation annular.

Woofer - idivayisi zobuchwepheshe ekwakhiweni yayo asetshenziswa yonke intuthuko yamuva ekukhiqizeni polymer. I diffuser kumelwe babe nokhahlo, amandla ikhoyili ke izodluliselwa ngaphesheya ubuso bayo ngokuphazima kweso, futhi kulula kuyashesha izici ngaphakathi the ngcosana kungenzeka isikhathi lag. Nokho, iningi izikhulumi eqolo futhi eliphezulu, Isimanga siwukuthi, naphezu kwayo yonke intuthuko kobuchwepheshe besimanje, iphepha isetshenziswa njengoba isikhulumi sokuqala, okuyinto yasungulwa ngo-1925 amaMelika amaphuzu Rice kanye Kellogg.

I woofer buye baba ingxenye ebalulekile Umklamo iyiphi isikhulumi eliphezulu ohlelweni.
