The passive piezoelectric buzzer generates sound based on the reaction of the piezoelectric effect. It is the basic principle that pressure change or strain is generated by applying an electric potential on a piezoelectric material. These passive piezo buzzers can be used to warn users of events cor
What is self-drive buzzer?Speaking of buzzers, we know two primary forms are piezoelectric buzzers, electromagnetic buzzers. both have active buzzers and passive buzzers. The piezoelectric buzzer has a piezoelectric buzzer plate, which contains two driving modes: self-drive buzzer and separately exc
The buzzer, also known as the sounder, is a miniaturized electro-acoustic device, which working principle can be divided into two types: piezoelectric buzzers and electromagnetic buzzers. Each type has specific characteristics. Generally speaking, the piezo buzzers are of higher reliability,
