Xaiv tus hais lus tsav tsheb raws li lub zog thiab qhov loj? Yog vim li cas koj lub qhov rooj ntse xauv lub suab ib txwm hnov tsis meej. Hauv tsab xov xwm no, peb yuav ua haujlwm los ntawm physics ntawm lub suab tsis tau hloov "lub siab xav" rau hauv "cov ntaub ntawv- tsav kev txiav txim siab."
I. Yog vim li cas Φ36mm yog qhov Sweet Spot rau Smart Door Lock Speaker Drivers
Lub qhov rooj xauv ntse muab qhov chaw txwv tsis pub tshaj rau cov neeg hais lus tsav tsheb- feem ntau tsuas yog 3-5 hli hauv qhov siab hauv lub roj teeb hauv qab lossis tom qab PCB. Φ36mm yog qhov ntev validated hla ntau pua lub qhov rooj ntse xauv qhov project:
36mm diam: Haum rau cov qauv sab hauv ntawm lub qhov rooj ntse ntse feem ntau, tsis txhob cuam tshuam nrog cov ntiv tes ntiv tes thiab cov xov tooj ntawm tes
Mounting qhov siab: 12.5-19.5mm: Xaiv tus qauv zoo raws li koj cov kab noj hniav tob
4Ω impedance + 2-3W ntsuas lub zog: Kev sib tw ncaj nraim nrog lub qhov rooj ntse xauv lub tshuab hluav taws xob chips - tsis xav tau kev txhawb zog
Xuanda Electronics (XDEC) tau nyob hauv kev lag luam electroacoustic rau 17 xyoo. Peb tau pom ntau lub qhov rooj xauv ntse ua lag luam raug kev poob vim yog kev xaiv tus neeg hais lus yuam kev -qee tus neeg muag khoom pom zoo rau qhov tsis ncaj ncees lawm mounting qhov siab, lwm tus xa cov khoom tsim nrog rhiab heev ntawm 20%. Kab lus no txiav los ntawm qhov tsis meej pem nrog lub hauv paus kev.
II. rhiab heev (SPL): 85dB yog qhov tsis yog -Ngotiable Threshold
rhiab heev ntsuas npaum li cas tus neeg hais lus tsav tsheb hloov hluav taws xob rau hauv lub suab siab, qhia hauv dB/m/1W. Ntse qhov rooj xauv yog ntsia rau ntawm lub qhov rooj vaj huam sib luag, yuav tsum tau npog tag nrho txoj kev nkag lossis txawm tias chav nyob. Hauv qab 85dB / m / 1W, lub suab tso zis yuav pom tsis muaj zog.
Lub physics: Txhua 3dB nce rhiab heev yog sib npaug rau ob npaug ntawm lub zog tso zis. Ib tus hais lus 87dB ntawm 1W ua rau tib lub suab siab li 84dB hais lus ntawm 2W. Rau lub roj teeb -lub qhov rooj xauv ntse ntse, qhov siab dua txhais tau hais tias qhov ntim txaus ntawm lub zog tsav qis dua- ncaj qha txuas lub roj teeb lub neej.
Kev ntsuam xyuas pom zoo: Thov tus neeg muag khoom pub dawb- teb rhiab heev nkhaus ntsuas nyob rau hauv ib nrab -anechoic chamber (1m nrug, liab suab nrov xeem). Tsis txhob cia siab rau daim ntawv spec tus nqi. Xyuas seb qhov zaus teb nkhaus yog du nyob rau hauv nruab nrab band (1kHz-4kHz) - qhov no ncaj qha txiav txim siab lub suab clarity.
III. Impedance Matching: 4Ω lossis 8Ω - Qhov no yog Kev Txiav Txim Siab
Ntse qhov rooj xauv lub tshuab hluav taws xob tso tawm feem ntau yog ntsuas ntawm 4Ω lossis 8Ω. Tsis sib haum xeeb impedance ntawm tus neeg hais lus tsav tsheb thiab lub suab nrov tso tawm tuaj yeem muaj los ntawm qhov ntim tsis txaus mus rau tus neeg hais lus puas tsuaj.
Txoj cai sib phim: 4Ω hais lus tsav tsheb yuav tsum ua ke nrog 4Ω amplifier outputs; 8Ω hais lus tsav tsheb nrog 8Ω outputs. Txuas lub 4Ω hais lus tsav tsheb mus rau 8Ω amplifier tso zis ua rau lub suab tsis muaj zog, nyias; rov qab configuration overheats thiab tuaj yeem rhuav tshem lub amplifier IC.
Feem ntau cov kev daws teeb meem ntawm lub qhov rooj xauv ntse (TI TAS5720, Silan SD6802, thiab lwm yam) yog tsim los rau 4Ω / 3W ncaj qha tsav. Ib tug Φ36mm multimedia hais lus tsav tsheb nrog 4Ω impedance yog tam sim no qhov tshaj plaws configuration. Kev lees paub qhov no thaum lub sijhawm xaiv tshem tawm 80% ntawm impedance{10}} cuam tshuam txog kev pheej hmoo.
IV. F0 Resonance zaus: Tsawg-Frequency pem teb uas txiav txim siab suab zoo
F0 (Free Air Resonance Frequency) yog qhov tsawg tshaj plaws resonant zaus ntawm tus neeg hais lus tsav tsheb hauv huab cua dawb. Lower F0 txhais tau hais tias sib sib zog nqus ntses bass thaj tsam txuas ntxiv thiab lub suab puv. Txawm li cas los xij, rau lub qhov rooj xauv lub suab nrov nrov, cov ntses bass thaj tsam tsis yog qhov kev txhawj xeeb tseem ceeb - tib neeg hais lus hauv paus ntsiab lus hauv 200Hz-1kHz ntau, yog li nruab nrab - rau-siab zaus teb tseem ceeb dua.
Kev pom zoo xaiv: Rau cov ntawv thov xauv lub qhov rooj ntse, F0 Tsawg dua lossis sib npaug li 500Hz txaus siab rau lub suab kom nrawm. Rau qhov xav tau ntau dua lub suab zoo (xws li, lub qhov rooj xauv qhov rooj nrog lub suab paj nruag), xaiv F0 Tsawg dua lossis sib npaug rau 350Hz tus tsav tsheb, qhov twg qis - zaus teb yuav pom tau ntau dua.
Yuav ua li cas txheeb xyuas: Thov tus xa khoom Thiele-Cov ntaub ntawv me me, tsom rau F0, Qms, thiab Qes. Cov kws tshaj lij muab cov ntaub ntawv no proactively. Yog tias tus neeg muag khoom hais tias "tsis muaj," nws yog ib qho teeb meem ceeb toom.
V. Lub Cev Dimensions thiab Mounting Compatibility: Qhov siab yuav ua rau muaj teeb meem ntau dua li txoj kab uas hla
