Xyoo 1954, Philippe txiv leej tub Woog, kws kho mob Swiss, tau tsim ib qho txhuam hniav hluav taws xob. 60 xyoo tom qab, tus txhuam hniav hluav taws xob zoo ib yam li nws tus thawj coj.
Hauv txoj cai, muaj ob pawg ntawm cov txhuam hniav hluav taws xob: kev sib hloov thiab kev co. Lub hauv paus ntsiab lus ntawm cov txhuam hniav rotary yog qhov yooj yim, uas yog, lub cev muaj zog tsav lub taub hau txhuam txhuam kom tig, uas ntxiv dag zog rau cov nyhuv txhuam hniav thaum ua qhov kev txhuam hniav zoo tib yam. Cov txhuam hniav rotary muaj zog, cov hniav nto huv si, thiab cov hniav sib txawv kuj tsis muaj zog. Txawm li cas los xij, nws tsis pom zoo kom siv nws rau lub sijhawm ntev vim qhov hnav loj ntawm cov hniav.
Kev vibration hom txhuam hniav yog qhov nyuaj thiab ntau dua high-end ntawm tus nqi. Cov txhuam hniav txhuam hniav muaj lub tshuab hluav taws xob uas muaj kev vibration hauv lub cev, uas tuaj yeem ua rau lub taub hau txhuam hniav tsim kom muaj cov zaus oscillation perpendicular mus rau cov kev taw qhia ntawm txhuam txhuam, tab sis qhov amplitude ntawm oscillation yog me me, feem ntau txog 5 hli nce thiab nqis, thiab qhov loj tshaj plaws amplitude ntawm oscillation nyob rau hauv kev lag luam yog 6 hli.
Thaum txhuam hniav, ntawm ib sab tes, lub siab-zaus txhuam hniav txhuam taub hau tuaj yeem ua tiav qhov kev txiav txim ntawm txhuam hniav; ntawm qhov tod tes, qhov kev vibration ntawm ntau tshaj 30000 zaug hauv ib feeb kuj ua rau cov tshuaj txhuam hniav sib xyaw thiab dej hauv qhov ncauj los ua kom muaj cov npuas me me. Lub siab tsim thaum cov npuas tawg tuaj yeem nkag mus tob rau hauv cov hniav kom ntxuav cov av.
