Mokhoa oa ho hokahanya li-tweeters ka crossover ho amplifier?

Theknoloji e tsamaile haholo ho tloha ha tweeter ea ka ea pele e kenngoa lilemong tse 15 tse fetileng, 'me li-tweeter tse ngata tsa morao-rao tsa theknoloji joale li tla le crossover e hahiloeng. Empa u ka fumana tse ling ntle le crossover. Maemong ana, haeba u tseba bohlokoa ba crossover, ua tseba hore u ke ke ua kenya li-tweeters ntle le tsona. Kajeno ke tla shebana le mokhoa oa ho hokahanya li-tweets tsa crossover ho amplifier.

Ka kakaretso, ho hokahanya tweeter ka crossover e hahelletsoeng ho amplifier, latela mehato ena.

• Ntlha ea pele, kopanya terata e ntle ea crossover ho terminal e ntle ea amplifier.
• Ebe o kopanya mohala o fosahetseng oa crossover ho terminal e mpe ea amplifier.
• Ebe o kopanya lipheletsong tse ling tsa crossover ho tweeter (e ntle le e mpe).
• Qetellong, hokela bakhanni ba bang ba kang woofer kapa subwoofers ho amplifier.

Ke phetho. Joale sistimi ea molumo oa koloi ea hau e tla sebetsa hantle.

Tsebo ea bohlokoa ka li-tweeters le li-crossovers

Pele re qala ts'ebetso ea khokahano, hoa hlokahala ho ba le tsebo e itseng mabapi le li-tweeters le li-crossovers.

Tweeter ke eng?

Ho hlahisa maqhubu a phahameng a 2000–20000 Hz, o tla hloka tweeter. Li-tweeters tsena li ka fetola matla a motlakase hore e be maqhubu a molumo. Ho etsa sena, ba sebelisa electromagnetism. Hangata li-tweeters li nyane ho feta li-woofers, subwoofers le bakhanni ba midrange.

woofers: Li-Woofers li khona ho hlahisa maqhubu ho tloha ho 40 Hz ho isa ho 3000 Hz.

Subwoofers: Monyetla oa ho hlahisa maqhubu ho tloha ho 20 Hz ho isa ho 120 Hz.

Bakhanni ba Midrange: Monyetla oa ho hlahisa maqhubu ho tloha ho 250 Hz ho isa ho 3000 Hz.

Joalo ka ha u ka inahanela, sistimi ea molumo oa koloi ea hau e hloka bonyane bakhanni ba babeli kapa ho feta ba ka holimo. Ho seng joalo, e ke ke ea khona ho tšoara maqhubu a itseng.

Crossover ke eng?

Leha lisebelisoa tsa libui tsa likarolo li etselitsoe ho hlahisa maqhubu a itseng, bakhanni bana ha ba khone ho sefa maqhubu. Bakeng sa sena o hloka crossover.

Ka mantsoe a mang, crossover e thusa tweeter ho hapa maqhubu a pakeng tsa 2000-20000 Hz.

Mokhoa oa ho hokela li-tweeters ho Li-crossovers tse hahiloeng ka har'a amplifier

Ho itšetlehile ka boemo ba hau, ho ka 'na ha hlokahala hore u nke mekhoa e fapaneng ha u hokahanya tweeter ea hau. Mohlala, li-tweeters tse ling li na le li-crossovers tse hahelletsoeng kahare mme tse ling ha li na tsona. Kahoo, ka mokhoa oa 1, re tla buisana ka li-crossovers tse hahiloeng. Re tla tsepamisa maikutlo ho li-crossovers tse ikemetseng ka mekhoa ea 2, 3 le 4.

Mokhoa oa 1 - tweeter e nang le crossover e hahiloeng

Haeba tweeter e tla le crossover e hahelletsoeng, u ke ke ua ba le mathata a ho kenya tweeter le ho e hokahanya. Hokela selelekela se setle sa tweeter pheletsong e ntle ea amplifier. Ebe o kopanya mohala o fosahetseng ho isa pheletsong e mpe.

Hopola: Ka mokhoa ona, crossover e sefa feela maqhubu a tweeter. E ke ke ea tšehetsa bakhanni ba bang ba kang woofer kapa subwoofers.

Mokhoa oa 2 - Ho hokela Tweeter ka kotloloho ho Amplifier e nang le Crossover le Sebui se felletseng sa Range

Ka mokhoa ona, o tla hloka ho hokahanya crossover ka kotloloho ho amplifier. Ebe u kopanya lipheletsong tse ling tsa crossover ho tweeter. Ka mor'a moo, re hokahanya bakhanni ba bang kaofela ho latela setšoantšo se ka holimo.

Mokhoa ona o motle bakeng sa ho hokahanya crossover e arohaneng le tweeter. Leha ho le joalo, crossover e tšehetsa tweeter feela.

Mokhoa oa 3 - Ho hokela tweeter hammoho le sebui se felletseng

Taba ea pele, hokela terata e ntle ea sebui se felletseng sa sebuela-hōle ho amplifier.

Ebe u latela mokhoa o ts'oanang bakeng sa terata e mpe.

Ebe o kopanya lithapo tse ntle le tse mpe tsa crossover ho lipheletsong tse ntle le tse mpe tsa sebui.

Qetellong, kopanya tweeter ho crossover. Ona ke mokhoa o motle oa ho boloka mohala oa sebui.

Mokhoa oa 4 - khokahano e arohaneng bakeng sa tweeter le subwoofer

Haeba u sebelisa subwoofer e nang le tweeter, li kopanye ka thoko ho amplifier. Ho seng joalo, tlhahiso e phahameng ea bass e ka senya kapa ea phatloha tweeter.

Ntlha ea pele, kopanya terata e ntle ea crossover ho terminal e ntle ea amplifier.

Ebe o kopanya mohala o fosahetseng ho isa pheletsong e mpe. Ebe o kopanya tweeter ho crossover. Etsa bonnete ba hore o hokahanya lithapo ho ea ka polarity.

Hona joale kopanya lithapo tse ntle le tse mpe tsa subwoofer ho mocha o mong oa amplifier.

Litlhahiso tse ling tse ka thusang mekhoa e ka holimo

Li-amplifiers tsa sejoale-joale li na le liteishene tse peli ho isa ho tse 2. Li-amplifiers tsena ka nako e le 'ngoe li ka khanna 4 ohm tweeter le 4 ohm full range speaker (ha li hokahane ka ho bapa).

Li-amplifiers tse ling li tla le li-crossovers tse hahiloeng. U ka sebelisa li-crossovers tsena tse hahelletsoeng ntle le mathata. Kamehla sebelisa crossover tweeter. Hape, le ka mohla u se ke ua hokahanya tweeter le subwoofer.

Bakeng sa ba batlang ntlafatso, kamehla ho molemo ho nkela crossover ea mantlha sebaka ka crossover e nang le libui tse peli.

Seo u lokelang ho se ela hloko nakong ea wiring

Ntle le wiring e nepahetseng, u ke ke ua khona ho hokahanya li-tweeter, crossovers, kapa subwoofers hantle. Kahoo, latela litataiso tsena bakeng sa litholoana tse ntle.

• U se ke ua ferekanya polarities ea lithapo. Mehlala e ka holimo, u ka tlameha ho sebetsana le lithapo tse 4 kapa tse 6. Kahoo, khetholla lithapo ka nepo 'me u kopanye likhoele ka tsela e nepahetseng. Mehala e mefubelu e emela lithapo tse ntle 'me mela e ntšo e emela lithapo tse mpe.
• Sebelisa lihokelo tsa crimp ho fapana le teipi ea motlakase. Ke likhetho tse ntle ka ho fetisisa bakeng sa ts'ebetso e joalo ea wiring.
• Ho na le mefuta e mengata e fapaneng ea lihokelo tsa crimp 'marakeng. Kahoo etsa bonnete ba hore u reka e nepahetseng bakeng sa lithapo tsa hau.
• Sebelisa terata ea 12 ho isa ho 18. Ho ipapisitse le matla le sebaka, gauge e ka fapana.
• Sebelisa lisebelisoa tse kang li-strippers le lisebelisoa tsa crimping nakong ea ts'ebetso ea khokahano e kaholimo. Ho ba le lisebelisoa tse joalo ho ka etsa phapang e khōlō. Ka mohlala, mochine oa terata ke khetho e ntle haholo ho feta thipa ea thuso. (1)

Moo u ka kenyang li-tweeters

Haeba u batla sebaka sa ho beha tweeter, leka ho e beha bohareng ba litulo tsa bapalami le bakhanni.

Hape, lemati la koloi kapa litšiea tse ka thōko tse haufi le fensetere ea moea le tsona ke libaka tse ntle tsa ho kenya tweeter. Boholo ba li-tweeter tse kentsoeng fekthering li kentsoe libakeng tsena.

Leha ho le joalo, ha u kenya li-tweeters, etsa bonnete ba hore u khetha sebaka se loketseng. Mohlala, batho ba bang ha ba rate ho beha tweeter bohareng ba dashboard. Molumo o lulang o le haufi le litsebe o ka li khopisa. Lemati la koloi ke sebaka se phethahetseng bakeng sa boemo bona. Hape, ha o kenya tweeter monyako oa koloi; Mekhoa ea ho cheka le ho kenya e bonolo haholo.

A na nka sebelisa li-tweeters ho subwoofer ea monoblock?

Sub amp ea monoblock e na le mocha o le mong feela mme mocha oo ke oa tlhahiso ea bass. Li-amplifiers tsa Monoblock ha li na maqhubu a phahameng. Kahoo, u ke ke ua kenya tweeter ho amplifier ea monoblock.

Leha ho le joalo, haeba u sebelisa amplifier ea liteishene tse ngata tse nang le crossover e tlase, latela mehato e ka tlase bakeng sa ts'ebetso e nepahetseng. (2)

• Ha u sebelisa amplifier ea likanale tse ngata, kamehla hokela tweeter ho kanale e sa sebelisoeng e felletseng.
• Haeba u sebelisa libui, hokela tweeter ka ho tsamaisana le libui.
• Leha ho le joalo, haeba ho se na liteishene tse sa sebelisoeng ho amplifier, u ke ke ua khona ho hokela twitter.

Keletso: Li-cross-pass crossovers li thibela maqhubu a phahameng 'me li lumella maqhubu ho tloha ho 50 Hz ho ea ho 250 Hz ho sebelisoa.

Ho akaretsa

Hore na o reka tweeter e nang le crossover e hahelletsoeng kapa crossover e arohaneng, o hloka ho hokela tweeter le crossover ho amplifier. Mokhoa o motle oa ho etsa sena ke ho hokahanya tweeter le kanaleng e sa sebelisoeng.

Ka lehlakoreng le leng, haeba u sebelisa subwoofer e nang le tweeter, latela tataiso e ka holimo ka nepo.

Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.
