Cov ntaub ntawv tseem ceeb ntawm tog neeg hais lus

Raws li cov khoom siv suab sib xyaw ua ke nrog cov khoom siv SPL siab, lub suab thiab lub teeb sib cuam tshuam, thiab kev txav mus los, cov neeg hais lus tog xav tau cov khoom siv uas sib npaug acoustic kev ua tau zoo, lub zog muaj zog, kev tiv thaiv ib puag ncig, thiab kev zoo nkauj. Lub cev muaj zog ntawm cov khoom sib txawv ncaj qha cuam tshuam rau qis - zaus txuas ntxiv, siab - zaus nkag, ua kom sov dissipation efficiency, thiab kav ntev. Yog li ntawd, cov tuam ntxhab feem ntau siv cov khoom sib txawv sib xyaw ua ke hauv cov txee, diaphragm, grille, cov khoom siv kho kom zoo nkauj, thiab cov khoom siv sab hauv, raws li cov khoom muag thiab kev siv cov xwm txheej, los tsim kom muaj kev ua tau zoo ntawm lub hauv paus tsim nyog rau kev teeb tsa tog.

Cov khoom txee yog lub hauv paus ntsiab lus txiav txim siab cov yam ntxwv acoustic. Cov kev daws teeb meem tseem ceeb suav nrog cov khoom siv ntoo sib xyaw, engineering plastics, thiab hlau alloys. Wood composite materials (such as multi-layer birch plywood and MDF) effectively suppress cabinet resonance due to their uniform density and moderate internal resistance, providing a pure reflection and radiation environment for low frequencies. Lawv yog ib qho kev xaiv rau cov kws tshaj lij- qib neeg hais lus, tshwj xeeb tshaj yog tsim rau sab hauv tsev lossis ib nrab- ib puag ncig uas yuav tsum tau muaj suab nrov. Engineering yas (xws li ABS thiab PP + iav fiber reinforced) yog lub teeb yuag, cuam tshuam -resistant, thiab yooj yim moldable. Complex curved nto thiab kev sib xyaw ua ke tuaj yeem ua tiav los ntawm kev txhaj tshuaj molding, txo kev thauj mus los thiab tuav cov khoom thauj thiab ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv sab nraum zoov. Cov hlau alloys (xws li aluminium alloy thiab galvanized steel) txo cov txee vibration vim lawv cov rigidity siab, txhim kho siab - zaus daws teeb meem thiab dynamic teb. Lawv feem ntau yog siv rau hauv cov thav duab lossis cov qauv kev txhawb nqa ntawm siab- qauv kawg, tab sis sab hauv damping yog tsim nyog kom tsis txhob muaj xim hlau xim.

Cov khoom siv diaphragm ncaj qha cuam tshuam rau qhov tseeb thiab qhov muaj zog ntau ntawm cov suab nrov. Cov neeg hais lus woofers feem ntau siv cov ntawv sib xyaw diaphragms (suav nrog cov pa roj carbon fiber lossis Kevlar fiber ntau) kom sib npaug ntawm cov qauv tsim thiab nruj, ua kom muaj zog bass thaj tsam txuas ntxiv thiab cov lus teb sai sai. Tweeters nyiam siv titanium alloy dome tweeters lossis silk diaphragms. Lub qub yog nruj heev thiab tshav kub- tiv taus, haum rau qhov kev xav tau nkag siab ntawm siab -dynamic- cov suab paj nruag hluav taws xob, thaum lub tom kawg yog mos thiab muaj cov lus teb du, ua kom zoo dua cov ntsiab lus ntawm cov suab thiab cov cuab yeej. Qee cov qauv muaj cov diaphragm passive qab lub woofer los txhim kho cov ntses bass thaj tsam; cov diaphragm no feem ntau yog ua los ntawm tib yam khoom raws li lub ntsiab diaphragm los yog ib tug thinner composite zaj duab xis, ncua qhov tsawg - zaus txwv los ntawm huab cua siab resonance.

Cov khoom siv grille yuav tsum sib npaug acoustic pob tshab thiab kev tiv thaiv kev ua haujlwm. Cov kev xaiv tseem ceeb muaj xws li hlau grilles (xws li stainless hlau los yog txhuas-magnesium alloy) thiab ntaub grilles (xws li polyester lossis nylon blends). Cov hlau mesh npog muaj zog thiab tiv taus deformation, tiv thaiv sab hauv los ntawm kev cuam tshuam sab nraud. Ib qho matte lossis sandblasted tiav yuav txo tau suab yoj diffraction. Npuag mesh npog yog mos, muaj cov acoustic impedance tsawg, thiab tsawg heev cuam tshuam rau siab -frequency attenuation. Lawv feem ntau sib xyaw ua ke nrog lub txee lub ntsej muag zoo nkauj, tab sis yuav tsum muaj cov txheej txheem dej tsis zoo los txhim kho huab cua tiv thaiv thiab ua tau raws li qhov xav tau ntawm cov dej noo thiab plua plav tiv thaiv ntawm qhov chaw sab nraum zoov.

Kho kom zoo nkauj thiab structural Cheebtsam yog qhov tseem ceeb ntawm ob qho tib si zoo nkauj thiab kev ua haujlwm zoo. High- cov qauv kawg feem ntau siv cov hlau txhuam txhuam, piano lacquer trim, lossis ntoo veneer, siv CNC precision machining thiab ntau- txheej txheej txheej txheej los txhim kho qhov muag pom. Cov khoom siv ua haujlwm (xws li rub pas nrig, lub log, thiab lub qhov cua grilles) feem ntau yog ua los ntawm aluminium alloy (ntsuas lub teeb yuag thiab lub zog) lossis hnav- roj hmab tiv taus (rau kev poob siab thiab kev poob siab). Cov log tsheb yuav tsum sib npaug ntawm cov load-cov kabmob muaj peev xwm thiab kev hloov pauv ntawm txoj kev, thaum rub cov pas nrig yuav tsum tau anodizing lossis hmoov txheej los tiv thaiv corrosion hauv qhov chaw sab nraum zoov.

Txawm hais tias cov khoom siv hluav taws xob sab hauv thiab cov khoom siv tiv thaiv tsis ncaj qha rau kev tsim cov acoustic, lawv yog qhov tseem ceeb rau kev ua kom ntseeg tau. Lub rooj tsav xwm hauv Circuit Court siv FR-4 epoxy board nrog cov txheej txheem sib txawv los tiv thaiv cov dej noo thiab plua plav corrosion. Lub roj teeb thiab lub zog module yog nyob ib puag ncig los ntawm cov nplaim hluav taws- ua npuas ncauj thiab thermally conductive silicone, txhim khu kev ruaj ntseg rwb thaiv tsev thiab optimizing tshav kub conduction. Cov txheej txheem sib khi (xws li cov ntaub thaiv npog npog thiab cov ntaub thaiv npog) feem ntau yog siv cov roj hmab silicone lossis EPDM roj hmab los xyuas kom lub sijhawm ntev ntawm IPX4 rau IPX7 tsis muaj dej tsis zoo thiab tsis muaj plua plav.

Hauv cov ntsiab lus, kev xaiv cov khoom siv rau tog neeg hais lus sawv cev rau tus ntoo khaub lig- kev qhuab qhia ntawm acoustic engineering, cov ntaub ntawv tshawb fawb, thiab kev tsim qauv: ntoo thiab cov ntaub ntawv sib xyaw ua rau lub hauv paus acoustic; engineering plastics thiab hlau alloys sib npaug portability thiab lub zog; diaphragm thiab grille cov ntaub ntawv precisely tswj cov zaus teb cov yam ntxwv; thiab cov ntaub ntawv zoo nkauj thiab kev tiv thaiv endow lub cuab yeej nrog ib puag ncig adaptability thiab aesthetic tus nqi. Qhov ntau-cov ntaub ntawv sib koom ua ke tsim qauv tso cai rau tus neeg hais lus kom ua tiav qhov sib npaug ntawm lub suab muaj zog thiab txhim khu kev qha zoo, muab kev txhawb nqa zoo rau cov kev paub dhau los hauv ntau qhov xwm txheej.
