Xaiv lub Mella hais lus zoo rau koj cov neeg siv khoom siv hluav taws xob tsis tuaj yeem lav qhov zoo tagnrho lub suab. Tseem muaj qhov tseem ceeb acoustic qauv tsim nyob rau hauv nruab nrab ntawm cov khoom thiab cov neeg siv kev paub. Xuantai Electronics, kos duab rau xyoo ntawm kev txhawb nqa cov neeg siv khoom, tau txheeb xyuas tsib qhov kev pom zoo tshaj plaws tsim qhov teeb meem thaum koom nrog Mella hais lus thiab muab cov kev daws teeb meem los pab koj cov khoom ua tiav thawj zaug, tshem tawm cov teeb meem ntawm "tsawg ntim" thiab "suab nrov".
Caw 1: Tsis quav ntsej tus qauv tsim ua ntej - vibration chamber thiab lub qhov tso zis suab, ua rau lub ntim loj poob.
Teeb meem tshwm sim: Thaum lub sij hawm sim ntawm chav hais lus, lub ntim tau txaus, tab sis thaum nws tau nruab rau hauv tag nrho lub tshuab, lub suab tau pom me me thiab muffled.
Lub hauv paus ua rau kev tsom xam: Sab pem hauv ntej ntawm lub diaphragm ntawm Marla hais lus xav tau ib qho chaw kaw me me (lub pre-auditory chamber), thiab lub suab yuav tsum tau ua los ntawm lub suab nrov. Yog hais tias qhov ntim ntawm lub pre-auditory chamber me dhau, qhov chaw ntawm lub qhov hluav taws xob lub suab tsis txaus, los yog txoj kev yog convoluted, lub suab kuj yuav nce sharply, uas ua rau ib tug tseem ceeb poob ntawm lub suab siab.
Xuanda Solution:
Pem hauv ntej baffle: xyuas kom meej tias muaj tsawg kawg yog 0.1 - 0.2 cc ntawm qhov chaw kaw ncaj qha rau pem hauv ntej ntawm lub diaphragm. Koj tuaj yeem siv qhov sib txawv ntawm qhov sib txawv ntawm cov cuab yeej siv thiab cov neeg hais lus, tab sis nws yuav tsum tau kho rau airtightness siv sealing ua npuas ncauj lossis silicone.
Lub qhov tso zis suab: Tag nrho cheeb tsam ntawm lub suab tso tawm lub qhov yuav tsum tsis pub tsawg tshaj 15-20% ntawm thaj chaw zoo ntawm tus hais lus diaphragm. Cov duab ntawm lub qhov yuav tsum zoo dua yog ib lub voj voog los yog ib qho array ntawm me me ncig qhov, tsis txhob ntev thiab nqaim slits. Lub suab tso zis channel yuav tsum luv thiab ncaj li sai tau.
Caw 2: Cov dej ntws tawm hauv lub chamber tom qab lossis lub ntim tsis txaus, ua rau poob qis - suab nrov zaus
Cov tsos mob tshwm sim: Lub suab yog nyias thiab qhuav, tsis muaj qhov tob. Tshwj xeeb tshaj yog, qhov kev ua tau zoo ntawm cov zaus tsawg yog qhov phem tshaj qhov xav tau.
Hauv paus ua rau kev tsom xam: Lub nraub qaum ntawm Meira hais lus diaphragm kuj yuav tsum muaj qee qhov chaw kaw (chamber nram qab) kom sib npaug ntawm huab cua. Yog hais tias lub ntim ntawm lub rear chamber yog me me heev, los yog yog hais tias muaj huab cua to los ntawm kev sib dhos qhov khoob, hlau qhov qhib, thiab lwm yam., qhov tsawg - zaus teb ntawm tus hais lus yuav deteriorate ntau.
Xuanda Solution:
Xyuas kom lub rear chamber kaw: Tsim ib tug tiav sealing qauv rau lub rear chamber. Cov xov hlau hla lub chamber yuav tsum tau kho thiab kaw siv lub tes tsho silicone lossis kua nplaum.
Optimized rear chamber ntim: Thaum qhov chaw tso cai, qhov loj dua lub rear chamber ntim, qhov muaj txiaj ntsig ntau dua rau kev txo qis -frequency enhancement. Cov txheej txheem sab hauv ntawm cov cuab yeej tuaj yeem muab tso rau kom khaws qhov chaw siab tshaj plaws tom qab tus neeg hais lus.
Trick 3: Cov qauv resonance thiab suab nrov txawv txav, ua rau muaj kev ntxhov siab "nias" suab
Teeb meem tshwm sim: Thaum ua si ib zaus (tshwj xeeb yog nruab nrab thiab siab zaus), lub cuab yeej lub casing lossis cov qauv sab hauv yuav tsim lub suab nrov "nias".
Lub hauv paus ua rau kev tsom xam: Cov kev vibrations tsim thaum lub sijhawm ua haujlwm ntawm tus neeg hais lus raug xa mus rau cov thinner lossis xoob ib puag ncig cov plhaub, cov hlua khi, thiab FPCs, ua rau muaj suab nrov. Qhov no tsis yog qhov teeb meem zoo ntawm tus neeg hais lus nws tus kheej, tab sis yog qhov tsis xws luag hauv kev tsim qauv acoustics.
Xuanda Solution:
Kev co damping installation: mos silicone pads los yog ua npuas ncauj yog siv los tshem tawm tus hais lus los ntawm lub tsev nyob rau hauv ib tug dawb- ntug yam, ua tiav txhua yam decoupling thiab thaiv txoj kev vibration kis tau tus mob.
Txhim kho cov qauv: Ntxiv cov hlua ntxiv los yog ua cov epoxy bonding hauv lub plhaub tsis muaj zog nyob ze ntawm tus neeg hais lus los hloov nws cov resonance zaus.
Kev rho tawm cov xov hlau: xyuas kom meej tias cov xov hlau ntawm tus neeg hais lus lossis FPC lub rooj tsavxwm hloov tau raug khaws cia kom deb ntawm lub diaphragm thiab raug kho nrog cov kua nplaum tiv thaiv kom tsis txhob vibrating thiab ntaus lwm yam khoom.
Npuag 4: Tsis muaj lossis tsim tsis tsim nyog ntawm kev tiv thaiv plua plav, tus neeg tua neeg zais ntawm kev ntseeg tau
Teeb meem tshwm sim: Qhov kev sim thawj zaug yog qhov qub, tab sis tom qab qee qhov kev siv, muaj suab nrov lossis txo qhov ntim, tshwj xeeb tshaj yog nyob rau hauv qhov chaw muaj plua plav.
Kev txheeb xyuas hauv paus: Cov plua plav, hws stains, thiab lwm yam khoom txawv teb chaws nkag los ntawm lub suab tso tawm lub qhov, ua raws li lub diaphragm, nce lub diaphragm qhov loj, cuam tshuam nws txoj kev txav, thiab txawm ua rau lub coil tau daig.
Xuanda Solution:
Nws yog ib qho tsim nyog rau nruab ib lub npog plua plav: Txuas lub npog tshwj xeeb acoustic breathable plua plav npog rau sab hauv ntawm lub qhov hluav taws xob lub suab lossis nyob rau pem hauv ntej ntawm tus neeg hais lus. Qhov no yuav tiv thaiv cov khoom txawv teb chaws los ntawm kev nkag mus thaum ua kom lub suab sib kis tau zoo.
Xaiv cov ntaub mesh kev tshaj lij: Siv cov plua plav tsim tshwj xeeb- cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj uas tau lees paub rau lub suab tsis kam. Tsis txhob siv cov ntaub npuag zoo tib yam los tiv thaiv kev poob ntau dhau ntawm - cov khoom siv zaus.
Caw 5: Kev siv tsis raug ntawm cov khoom ntim hauv cov kab noj hniav, ua rau acoustic luv Circuit Court
Teeb meem tshwm sim: Txhawm rau daws lwm yam teeb meem (xws li cua sov dissipation, kho), daim txhuam cev zoo tib yam los yog gel tau ntim rau hauv cov lus hais kab noj hniav, ua rau lub suab nrov nrov thiab dullness.
Root cause analysis: In the acoustic cavities at the front and rear of the speaker, non-breathable or high-density materials were wrongly filled, which is equivalent to physically "covering" the diaphragm, thereby disrupting the aerodynamic environment necessary for its normal operation.
Xuanda Solution:
Ua kom huv huv ntawm cov kab noj hniav acoustic: Nws raug txwv nruj kom tsis txhob random sau cov ntaub ntawv uas tsis yog -acoustic tsim nyob rau hauv pem hauv ntej thiab nram qab kab noj hniav.
Yog tias xav tau kev nqus suab, siv cov ntaub ntawv tshaj lij: Yog tias koj xav tau kho lub suab lossis tshem tawm cov suab nrov tshwj xeeb, siv lub suab tshwj xeeb acoustic - nqus cov paj rwb (xws li PU ua npuas ncauj nrog cov porosity siab), thiab ua raws li kev taw qhia ntawm tus engineer.
Cia Xuantada Electronics ua koj tus khub tsim acoustic.
Txhawm rau zam cov teeb meem no, yuav tsum muaj kev sib koom ua ke ntawm kev paub theoretical thiab kev ua tau zoo. Xuantada Electronics tsis yog tsuas yog muab cov hais lus tab sis kuj muaj tag nrho - saw acoustic tsim kev txhawb nqa los ntawm cov khoom mus rau cov khoom tiav. Peb tuaj yeem muab cov neeg siv khoom nrog:
Kev tshuaj xyuas pib tsim: Raws li koj cov khoom ID thiab cov duab kos duab, txheeb xyuas cov kev pheej hmoo ntawm acoustic ua ntej.
Customized solution: Peb muab cov lus hais sib xyaw ua ke uas suav nrog kev sib khi, plua plav- pov thawj thiab kev teeb tsa, txo qhov nyuaj thiab pheej hmoo ntawm koj cov txheej txheem kev koom ua ke.
Cov qauv nrawm thiab kev txhawb nqa debugging: Ua kom koj cov txheej txheem tsim khoom.
Summary: Ib qho kev paub zoo tshaj plaws yog qhov tshwm sim ntawm kev sib xyaw ntawm "cov khoom zoo heev" thiab "zoo heev tsim". Los ntawm kev zam cov pitfalls no, lub microphone hais lus koj xaiv tuaj yeem ua tau tiag tiag qhia lawv lub peev xwm thiab ntxiv qhov ua tiav rau cov neeg siv kev paub ntawm koj cov khoom.
