Piezoelement "chayqaluvchi"

Piezo buzzer strukturaviy ravishda o‘tkazgichli keramika bilan qoplangan metall plastinka bilan ifodalanadi. Plastinka aloqa vazifasini bajaradi. Qurilma qutblangan, o‘zining "+" va "-" belgilariga ega. Buzzer printsipi XIX asr oxirida aka -uka Kyuri tomonidan topilgan piezoelektrik effektga asoslangan. Uning so‘zlariga ko‘ra, zilga elektr energiyasi berilsa, u deformatsiyalana boshlaydi. Bunday holda, kerakli chastotadagi "shovqin" chiqaradigan metall plastinkaga zarbalar bo‘ladi.

Xulosa
Bu amaliy ishni bajarish orqali shuni o’rgandimki biz shift registirlari orqali pinlarni ko’paytirib kattaroq proyektlarni yasasak bo’ladi ekan. Yana Piezoelement nima ekanligi va u + va – ma’lumot qabul qilishi unda ovozlar bilan ishlashimiz mumkin ekanligini o’rgandim.
