Ntau hom tsav tsheb
Muaj ntau hom drives lub luag haujlwm rau ntau zaus. Cov tsav tsheb hluav taws xob yuav ua haujlwm tau zoo tshaj plaws nyob rau hauv ib qho kev txwv ntau zaus, thiab ntau tus tsav tsheb feem ntau yog sib xyaw ua ke los ua kom tiav cov lus hais kom ua tau zoo tshaj qhov txwv no. Cov ntsiab lus ntawm tag nrho cov tsav tsheb no tau teev tseg hauv qab no.
1. Tag nrho cov tsav tsheb
Tus neeg tsav tsheb tuaj yeem siv ib leeg txhawm rau txhawm rau tsim lub suab channel, thiab tsis tas yuav muaj kev pab los ntawm lwm tus tsav tsheb. Yog li ntawd, nws yuav tsum tau npog tag nrho cov suab ntau. Hom tsav tsheb no me me, feem ntau yog li 7.6-20.3 cm (3-}8 nti) inch, yog li nws tuaj yeem ua tiav qhov tsim nyog siab - zaus teb. Cov neeg tsav tsheb puv puv feem ntau pom muaj nyob hauv TV, cov chaw nyob pej xeem, walkie-talkies, thiab cov txais me me.
Lub tshuab suab, qee lub computer hais lus, thiab lwm yam.
2. Nruab nrab -ntau tus tsav tsheb
This speaker driver can reproduce different frequency bands usually between 1 and 6 kHz; therefore, it is called "mid frequency", which means between the woofer and the tweeter. Vibration of the midrange unit
Lub membrane yog ua los ntawm cov khoom sib xyaw lossis ntawv. Lawv kuj tuaj yeem yog cov tsav hluav taws xob ncaj qha, zoo ib yam li cov woofers me. Xwb, lawv tuaj yeem ua tus tsav tsheb compression, zoo ib yam li qee tus qauv tweeter. Tsis tas li ntawd, tus tsav tsheb nruab nrab raws li lub tshuab hluav taws xob ncaj qha tuaj yeem kho tau ntawm lub hauv ntej baffle ntawm tus neeg hais lus vaj tse. Nyob rau hauv cov ntaub ntawv ntawm tus neeg tsav tsheb compression, nws tuaj yeem kho ntawm lub caj pas ntawm tus neeg hais lus kom ntxiv cov zis ntau ntxiv thiab cov qauv hluav taws xob tswj.
3. Tsawg zaus tsav tsheb (subwoofer thiab subwoofer)
The frequencies generated by these drivers are in the lower range. Low frequency drivers are called woofers and subwoofers. These drivers use low-frequency waves to make a "whee" sound compared to the bird's "call" that usually occupies the top position of the audio spectrum, so their name comes from the dog's bark.
Thaum nws los txog rau qhov sib txawv ntawm lub subwoofer thiab subwoofer, nws yog lawv qhov sib txawv zaus. Thaum tham txog lawv qhov ntau zaus, woofers feem ntau ua haujlwm nyob rau hauv 40-500 Hz ntau, thaum subwoofers nyob hauv qab 100 Hz. Tsis tas li ntawd, feem ntau cov neeg hais lus feem ntau muab cov woofer thiab subwoofer rau hauv ib tus neeg hais lus. Txawm li cas los xij, thaum txhim kho lub suab ncaj ncees, ob tus neeg hais lus tau sib cais raws li kev huv, huv si, thiab ntau lub suab ua kom zoo dua ntawm qhov tsawg zaus.
4. Tweeter
Tus tsav tsheb no yog hu ua tus tsav tsheb siab - zaus thiab yog lub luag haujlwm rau kev tsim cov zaus ntau tshaj plaws hauv cov lus hais. Ntawm qhov tod tes, muaj teeb meem nrog tus tsim ntawm tweeter. Nws yog qhov nyuaj kom ua tiav qhov dav - lub kaum sab xis lub suab, vim tias thaum nws los txog rau siab - lub suab zaus, tus neeg hais lus feem ntau yog sab laug hauv qhov nqaim. puab. Tsis tas li ntawd, tweeters nrog lub dome mos tuaj yeem pom hauv lub suab nrov hauv tsev, thiab nws tsis yog qhov tsis yooj yim los nrhiav cov neeg tsav tsheb compression nrog cov neeg hais lus hauv kev tshaj lij lub suab. Tsis tas li ntawd, nyob rau hauv xyoo tas los no, ribbon tweeters tau dhau los ua neeg nyiam heev vim tias lub zog tso zis ntawm qee qhov qauv tsim tau nce mus txog qib uas muaj txiaj ntsig zoo rau kev ua haujlwm lub suab. Tsis tas li ntawd, lawv cov hom tso zis ntau dua nyob rau hauv lub dav hlau kab rov tav, uas yog ib qho yooj yim hom rau kev hais kwv txhiaj suab.
5. Coaxial tsav tsheb
Hom tsav tsheb no hu ua tus hais lus tsav tsheb, thiab nws muaj ob lossis ntau tus tsav tsheb sib xyaw ua ke. Cov hom tsav no yog tsim los ntawm ntau lub tuam txhab, xws li Pioneer.
Tannoy, Altec, Genelec, BC Speakers, Cabasse, SEAS, KEF, BMS, thiab lwm yam.
nyob rau hauv xaus
Qhov tseeb, cov neeg tsav tsheb tuaj ntawm cov duab sib txawv thiab ntau thiab tsawg. Txawm li cas los xij, feem ntau, cov tsav tsheb loj feem ntau yog tsim los rau qis zaus, thiab rov ua dua. Qhov no yog vim hais tias ntau zaus yuav tsum tau lub suab tsis nyob ze cov ntsiab lus siab thiab tsis tshua muaj siab. Yog li ntawd, qhov luaj li cas ntawm tus tsav lub khob hliav qab yuav tsum me me kom nws thiaj li yooj yim txav mus los kom ruaj. Tsav nrog qhov me me yuav pom tias nws nyuaj dua los tswj cov zaus qis dua. Qhov no yog vim qhov qis zaus txav rov qab thiab tawm qeeb qeeb dua li qhov siab dua.
