Thov kev cia siab ntawm tooj liab ua npuas nyob rau hauv microphone diaphragms

Thov kev cia siab ntawm tooj liab ua npuas nyob rau hauv microphone diaphragms

1. Kev xav tau thiab cov kev sib tw ntawm microphone diaphragms
Raws li cov tub ntxhais lub suab rau suab sau, kev ua haujlwm ntawm lub microphone ntawm lub microphone ncaj qha cuam tshuam rau lub suab zoo. Nqa cov qog ua kom zoo li cov piv txwv, cov diaphragm yuav tsum muaj cov ntsiab lus siab (feem ntau}}}}}. Txawm hais tias cov khoom siv ua yeeb yam xws li MyLarragm xws li PVC yog tus nqi-tswj tau, lawv muaj teeb meem xws li cov kev ua kom dav dav dav dav. Qhov tshwj xeeb tshaj yog cov kev cuam tshuam ib puag ncig, kev rov ua haujlwm hauv hluav taws xob feem ntau yuav tsum tau ua kom sai li cas los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kom muaj qhov uas twb muaj lawm.

2. Kev tsom xam ntawm lub acoustic cov teeb meem ntawm tooj liab ua npuas
Raws li ib tug peb - qhov chaw siv hluav taws xob hlau, tooj dag ua npuasy muaj cov qauv acoustic zoo heev vim nws cov qauv tshwj xeeb:
Broadband silencing mechanism: nws tus pore qauv tuaj yeem ua rau lub suab sib zog ntawm kev tsis sib haum xeeb ntawm kev npau taws, nthuav dav thiab micropore respection. Cov kev tshawb fawb tau pom tias qhov nqus tau ntawm 10kHz suab nthwv dej los ntawm kev ua npuas ncauj liab nrog ib tuab ntawm 5 hli tuaj yeem ncav cuag ntau dua 70%.
Electromagnetic shielding effectiveness: Copper material itself has electromagnetic shielding capabilities similar to silver (shielding effectiveness>60db), thiab cov qauv ntxeem tau ntxiv txhim kho cov pa hluav taws xob hluav taws xob hluav taws xob electromagagnetic ntawm cov khoom siv hluav taws xob hauv suab.
Cov txheej txheem nraaj qauv ua npuas ncauj

3. Cov qauv hloov pauv ntawm tooj liab ua npuas nyob hauv Diaphragm Tsim
Kev rhiab thiab cov sib npaug sib npaug: lub teeb ci ntsa iab (qhov ntom ntom ntom (> 500m² / mp) thiab thaj chaw tshwj xeeb) thiab muaj peev xwm los teb cov suab tsis muaj zog. Los ntawm kev tswj cov porosity (70% -90%), lub inertial lub zog, thiab cov lus teb hloov tuaj yeem ua kom zoo.
Txhim kho thermal stability: nws thermal conductivity (> 100W / (MEX KIS) yog 1-2 kev ua kom sai li cas los ntawm kev co los ntawm kev co thiab tsis txhob mob siab rau qhov kub thiab txias hloov.
Corrosion tsis kam thiab durability: ua npuas ncauj ua npuas dej tom qab kev kho mob oxidation tuaj yeem hloov kho kom zoo rau cov khoom siv, tshwj xeeb yog tsim nyog rau sab nraum zoov lossis kev ua haujlwm sab nraud.

4. Kev thov cov xwm txheej thiab kev siv txoj hau kev
Siab -}}}} Cov ntaub ntawv sau ua npuas dej: Siv npuas this - Zoo li cov duab pob zeb diamond} zoo li kev sib npaug ntxim nyiam. Kev sim cov ntaub ntawv qhia tau hais tias qhov distortion ntawm cov qauv sib dhos tuaj yeem txo qis rau hauv qab 0.01% ntawm 1kHz.
Lub suab nrov ib puag ncig: Siv cov yam ntxwv sib xyaw ntawm cov tawv nqaij tooj liab thiab acoustic txo cov khoom lag luam sab nraud, uas haum rau cov cuab yeej kaw cov ntaubntawv povthawj siv.
Tshwj xeeb kev yoog raws: rau kev soj ntsuam kev lag luam lossis aerospace Diaphragm tuaj yeem tiv thaiv kev ua npuas ncauj kom ntseeg tau tias muaj teeb meem tseem ceeb.
