Kev tsom xam zaus: 500Hz–2kHz tib neeg hais lus band, tsis puv -ntau lub suab
Standard multimedia hais lus tsav tsheb yog tsim los rau ntau zaus kev pab them nqi. Tab sis lub tswb nrov tsuas yog xav tau los tsim tib neeg hais lus kom meej. Qhov no yog qhov twgMylar hais lus tsav tshebexcel - nyias daim nyias nyias, teb ceev ceev, optimized rau lub suab zaus.
2. Φ28mm Mylar Speaker Tsav Tsheb: Txoj Cai Loj rau Doorbell daim ntaub ntawv
Qhov loj Φ28mm hits qhov chaw qab zib rau embedded doorbell installations:
| Parameter | Yam tsawg kawg nkaus | Hwm Standard | Pitfall Alert |
|---|---|---|---|
| Ntau zaus | 500Hz-8kHz | 400Hz-10kHz | Tshawb xyuas tib neeg hais lus tshwj xeeb |
| rhiab heev | Ntau dua lossis sib npaug li 85dB | Ntau dua lossis sib npaug li 90dB | Kev siv sab hauv tsev xav kom pom tseeb ntawm 2-3m nrug |
| Rated zog | Ntau tshaj los yog sib npaug rau 0.5W | Ntau tshaj lossis sib npaug rau 1W | tuav lub suab tawg tsis muaj kev puas tsuaj |
| Mounting Qhov tob | Tsawg dua los yog sib npaug li 8 hli | Tsawg dua los yog sib npaug li 6 hli | Tshawb xyuas vaj huam sib luag thickness ua ntej xaj |
| Impedance | 4Ω lub 8Ω | 8Ω (lub neej roj teeb zoo dua) | Roj teeb - cov chav nyob yuav tsum siv 8Ω |
💡 Field Test Tip: Ua ntej ntau lawm, sim lub suab lees paub tus nqi. Puas muaj ib tus neeg hais tias "nyob zoo" thiab "Kev xa khoom" ntawm 1 meter nrug - tuaj yeem siv sab hauv tsev kom paub qhov txawv cov lus yam tsis tau saib cov ntsuas?

Siab zog rub: Tag nrho - cov tsav tsheb ntau xav tau lub zog ntau dua los tsim cov zaus qis, tso roj teeb sai dua
Slower transient teb: Lub suab nres suab "blurred" ntawm cov tsav tsheb optimized rau suab paj nruag
Tus nqi siab dua: Engineering rau tag nrho -kev tsim tawm ntau ntxiv ntxiv cov nuj nqis uas tsis tsim nyog
Mylar hais lus tsav tsheb yog lub hom phiaj- tsim rau kev sib tshuam siab - lub zog siv lub suab:
Tsawg standby tam sim no, instant ncov teb
