Kev txhais ntawm electrostriction
Electrostriction yog qhov cuam tshuam ntawm cov nyhuv piezoelectric. Qee cov iav ci ua kom ntev lossis ua kom luv lawv cov deformation hauv qab qhov hluav taws xob, hu ua electrostriction. Cov nyhuv ntawm kev siv hluav taws xob tuaj yeem siv los hloov hluav taws xob kev hloov mus rau hauv kev siv tshuab kev co, uas feem ntau siv hauv lub tshuab pauv hloov uas tsim hluav taws xob, nrog rau lub mloog pob ntseg thiab tweeter.
