Ua raws li qhov no hauv kev txiav txim siab, koj yuav ua li cas thiaj ua tau ib lub tshuab hluav taws xob passive?

Rau tsim ib tug passive radiator alignment, pib nrog ib qho yooj yim ported alignment siv tus tsav tsheb uas muab qhov xav tau lub thawv loj thiab teb zaus. Tom qab ntawd, siv txoj kab uas hla uas koj xaiv passive radiator raws li "chaw nres nkoj txoj kab", thiab siv qhov no los laij qhov chaw nres nkoj xav tau ntev.

Ib tus kuj yuav nug, cov passive radiators zoo? Passive radiators tau siv ntau tus neeg hais lus niaj hnub no vim tias lawv yog txoj hauv kev zoo heev kom tau txais tag nrho ntau ntxiv ntawm oomph tawm ntawm lub suab kaw lus yam tsis tau hloov pauv lub zog muaj txiaj ntsig los tsim cov txiaj ntsig zoo nkauj ntses bass thaj tsam uas peb txhua tus nyiam heev.

Xav txog qhov no, thaum twg koj yuav tsum siv lub passive radiator?

Passive radiator laij lej - enclosure tsim

1. Lub thawv ntim: V_b = V_{raws li} / α = 95 / 2.78 = 34.17 L.
2. Tuning zaus: f_B = H * f_s = 1.51 * 21 = 32 Hz.
3. – 3 db: f₃ = (f₃/f_s) * f ib_s = 1.59 * 21 = 34 Hz.
4. Kev hloov pauv PR: V_{ua pr} = (V._{ua pr}/V_d) * V ua_d Luas = 2.35 * 0.00044 = 0.001034 m³
