Buzzer kev faib tawm
1, raws li lub hauv paus ntsiab lus ntawm nws txoj kev tsav tsheb, muab faib tau rau hauv: cov pob zeb ua haujlwm (nrog rau kev tsav tsheb, tseem hu ua nws tus kheej txaus siab buzzer) thiab passive buzzer (sab nrauv tsav, kuj hu ua nws cov kev ua zoo nkauj Sounder)
2, raws li txoj kev sib txawv, yuav muab faib ua: electromagnetic buzzer thiab piezoelectric buzzer;
3, raws li qhov txawv ntim, yuav muab faib ua: DIP BUZZER (tus pin buzzer) thiab SMD BUZZER (thaj pobzeb);
4, raws li qhov sib txawv ntawm qhov tam sim no, yuav muab faib ua: DC buzzzer thiab AC pob plebzer, ntawm lawv, piezoelectric buzzer nrog DC, siv cov tshuab piezoelectric, uas yog, thaum sab nraud quab yuam ua piezoelectric khoom tshwm sim Cov khoom piezoelectric generates tus nqi them thaum deformed. Kuj, cov khoom piezoelectric deforms thaum lub zog.
