Cov hlau nplaum sab hauv tus neeg hais lus yog pab txhawb kev co, cov hlau nplaum yuav tsim ib qho chaw sib nqus, cov lus hais lub suab tau muab tso rau hauv qhov chaw sib nqus, thaum lub suab coil los ntawm lub suab tam sim no, qhov tam sim no yuav yog lub zog ntawm cov hlau nplaum, yog li ntawd. lub suab coil vibration, tsav thiab lub suab coil lo ua ke ntawm daim ntawv basin vibration suab.
Cov hlau nplaum hais lus feem ntau muaj cov hlau nplaum zoo tib yam ferrite thiab Ndfeb hlau nplaum. Cov neeg hais lus ntawm qhov tseeb nyob ib ncig ntawm cov hlau nplaum coil, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tus neeg hais lus yog siv cov teeb liab acoustic rau hauv hluav taws xob teeb liab, kev hloov pauv rau kev sib kis ntawm lub teeb liab acoustic, thaum peb lub suab mus rau hauv tus neeg hais lus, tuaj yeem tsim cov kev hloov pauv ntawm cov kauj tam sim no ua rau sib nqus, thiab hlau nplaum nyiam los yog repel txav muaj qee yam tsis tu ncua, kev co thiab yog li tsav cov ntawv lub khob vibration, Tig lub suab. Yog li, cov hlau nplaum txoj haujlwm yog los pab kev vibration.
