Ana samar da sauti ta hanyar girgiza. Raƙuman sauti suna tafiya ta cikin iska, kuma idan suka haɗu da wani abu mai ƙarfi, za su aika wannan girgizar zuwa ga abu mai ƙarfi. Abubuwan da ake sarrafa murya su ne irin waɗannan abubuwa masu saurin girgiza waɗanda ake kunnawa idan akwai sauti (juriya ta zama ƙarami) kuma ana katse su idan babu sauti (juriya ta zama babba). Sannan ta hanyar yin jinkiri tsakanin da'irar da guntu, ana iya tsawaita da'irar na tsawon lokaci idan akwai sauti.

4, ƙa'idar aiki ta fitilar induction haske

Na'urar firikwensin haske tana fara gano ƙarfin hasken kuma tana yanke shawara ko za ta tsaya a kulle kowace na'urar firikwensin LED infrared. Akwai yanayi biyu:

A lokacin rana ko kuma lokacin da hasken yake da ƙarfi, na'urar induction ta gani tana kulle na'urar induction ta infrared da kuma na'urar canza jinkiri bisa ga ƙimar induction.

Da daddare ko lokacin da hasken ya yi duhu, na'urar firikwensin gani za ta sanya na'urar firikwensin infrared da na'urar canza jinkiri a cikin yanayin jiran aiki bisa ga ƙimar firikwensin.

A wannan lokacin, idan jikin ɗan adam ya shiga kewayon induction na fitilar, na'urar infrared induction za ta fara aiki ta gano siginar, kuma siginar za ta kunna na'urar canza jinkiri don buɗe fitilar infrared ta LED. Idan mutumin ya ci gaba da motsawa a cikin kewayonsa, hasken firikwensin jiki na LED zai kasance a kunne, lokacin da mutumin ya bar kewayonsa, babu siginar firikwensin infrared, kuma maɓallin jinkirtawa yana kashe hasken firikwensin infrared na LED ta atomatik a cikin ƙimar saita lokaci. Kowane na'urar yana komawa zuwa jiran aiki kuma yana jiran zagaye na gaba.
