Lub suab "buzzing" feem ntau yog qis - nrov nrov, nyob ib ncig ntawm50-60 Hz, zoo ib yam li lub xov tooj vibrating lossis kab ya nyob ze. Qee lub sij hawm nws tas li, qee zaum nws los thiab mus.
Buzzing feem ntau qhiahluav taws xob cuam tshuam, teeb meem hauv av, lossis teeb meem thaiv kab. Tab sis nws kuj tuaj yeem txhais tau hais tias kev puas tsuaj sab hauv.
1. Suab nrov
Tsawg- lub suab vibration zaus (50–60 Hz).
Feem ntau tshwm sim los ntawm kev cuam tshuam fais fab, xaim, lossis cov khoom xoob xoob.
2. Humming
Qhov tob dua, tas li 60 Hz hum uas uatsis yoghloov nrog ntim.
Feem ntau tshwm sim los ntawmhauv av loops.
3. Ntshai
Siab -frequency "ssss" suab nrov - ncig100-120 Hz.
Feem ntau thaum nce siab dhau lawm, cables tsis thaiv, lossis qhov chaw tsis nrov.
4. Popping & Cracking
Ntse clicks los yog pops thaum playback lossis thaum tig cov khoom siv rau / tawm.
Feem ntau tshwm sim los ntawmxoob cables los yog static paug.
5. Distortion
Lub suab nrov nkig, tawg, lossis "cipped."
Feem ntau qhov tshwm sim ntawmoverpowering los yog hais lus puas.
6. Lub suab nrov nrov
Suab nrov uas tuaj thiab mus irregularly.
Qhov no feem ntau txhais tau tiasxoob xaim lossis lub zog tsis ruaj khov.
1. Kev cuam tshuam hluav taws xob
Cov khoom siv hluav taws xob nyob ze xws li routers, LED teeb, khoom siv hluav taws xob, lossis xov tooj cua tuaj yeem xa cov teeb liab electromagnetic.
IP Speakers amplified internally yog tshwj xeeb tshaj yog rhiab heev.
2. Cov teeb meem hauv av
Cov khoom siv txuas nrog cov hluav taws xob sib txawv ua rau "voj", tsim kom muaj 60 Hz hum.
3. Faulty los yog Tsawg-Quality Cables
Ntau tshaj 70% ntawm cov suab nrov peb pom hauv chav kuaj los ntawm cov kab hluav taws xob puas lossis tsis zoo.
4. Kev tiv thaiv kab mob tsis zoo
Unshielded cables ua zoo li cov kav hlau txais xov thiab nqus kev cuam tshuam.
5. Noisy Audio Source
Cov khoos phis tawj qub, tus IP audio decoders tsis tu ncua, lossis cov neeg siv xov xwm pheej yig feem ntau qhia cov suab nrov tom qab.
6. Analog ntaus suab nrov
Legacy analog mixers thiab microphones ib txwm ua rau nws hnov.
7. Siab Amplifier Tau Txais
Kev nce ntau dhau ua rau cov suab nrov me me pom tau.
8. Cov kab hluav taws xob tsis zoo
Ntev cable khiav (tshaj 70-100 m) nce suab nrov hauv PA thiab IP suab tshuab.
9. Lub zog tsis ruaj khov
Fluctuating voltage los yog qias neeg zog ua rau humming.
10. Xov tooj cua Frequency Interference (RFI)
Cov tsev nyob ze ze, ob- xov tooj cua, lossis walkie-talkies tuaj yeem xau rau hauv lub tshuab suab.
11. Computer Suab nrov
Sab hauv PC Cheebtsam (kiv cua, SSDs, GPUs) tsim suab nrov kis los ntawm USB / AUX.
12. Transformer vibration
Pheej yig transformers vibrate thiab ua rau sab hauv buzzing.
13. Kev puas tsuaj ntawm tus hais lus
Torn cones, burnt coils, los yog xoob sab hauv thaiv ncaj qha ua buzzing.
1. Xyuas tag nrho cov Cables ua ntej
- Xyuas kom cov kev sib txuas yog nruj
- Hloov cov kab qub lossis puas
- Tsis txhob siv cov cables uas pheej yig tshaj - lawv feem ntau ua tsis tau
2. Siv High-Quality shielded Cables
- Shielded cables tuaj yeem txiav suab nrov txog li90%.
3. Cais Suab Cables los ntawm Fais Fab Cables
- Tsis txhob khiav lawv parallel mus rau qhov ntev.
4. Kho cov teeb meem hauv av
Siv:
- Hauv av voj isolators
- Ib lub zog sib koom ua ke
- Cov kab sib npaug
5. Txhim kho lub zog zoo
Sim:
- Surge tiv thaiv
- Lub zog txias
- UPS rau qhov chaw tsis ruaj khov
6. Txo qhov nce lossis ntim
- Txo qhov tsis tsim nyog amplification.
7. Kuaj Lwm Lub Suab
Ua suab los ntawm:
- Lwm lub xov tooj
- Lwm lub computer
- Ib tug tshiab IP suab kwj
8. Hloov cov khoom siv
- Sim AUX → USB → Network Input (rau tus hais lus IP).
9. Re-pair Wireless IP Speakers
- Ib qho yooj yim re-pairing tuaj yeem tshem tawm cov suab nrov.
10. Tshawb xyuas tus neeg hais lus sab hauv
Yog tias txhua yam ua tsis tiav, tus kws kho mob yuav tsum tau kuaj xyuas:
- Loos coils
- Loose solder ntsiab lus
- Kev puas tsuaj amplifier board
| Parameter | Pom zoo tus nqi | Kev cuam tshuam rau lub suab nrov |
|---|---|---|
| Teeb liab -rau-Noise Ratio (SNR) | Ntau dua lossis sib npaug li 90 dB | Siab dua SNR=tsawg dua |
| Tag nrho Harmonic Distortion (THD) | < 0.5% | Tsawg THD=ntshiab suab |
| Fais fab mov stability | ± 2% kev cai | Tiv thaiv hum/buzz |
| Cable Ntev | < 70 m | Cov kab ntev ntev ua kom nrov nrov |
| Amplifier Tau Txais | Qib nruab nrab | Kev nce ntau dhau ua rau nws nce siab |
| Tiv thaiv qib | Muab ob npaug -shielded | Txo kev cuam tshuam txog li 90% |
