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,
As a kind of electronic buzzer, the main energy of active piezo buzzer is provided by direct current. There are many types of buzzers, which can be classified according to current, package, structure and driving mode.
How does a piezo buzzer work?The piezo buzzer uses the piezoelectric effect of the piezo ceramics and uses the pulse current to drive the vibration of the metal plate to generate sound and is widely used as a sounding device in electronic products such as computers, home appliances，consumer electron
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
What is the difference between active and passive buzzer?The buzzer, also known as the sounder, is a miniaturized electro-acoustic device, for which working principle can be divided into two types: piezoelectric buzzers and electromagnetic buzzers. Also, even these two categories can be further subd
What is the function of the passive piezo buzzers?The piezo buzzer is an electronic buzzer with an integrated structure powered by a DC/AC voltage and is widely used as a sounding device in electronic products such as computers, telephones, timers, printers, copiers, alarms, electronic toys, househo
A piezo buzzer is an audio signalling device that uses piezoelectric ceramics as an electro-acoustic transducer. The core of this device is a transducer made of a piezoelectric ceramic sheet pasted onto a metal sheet, that is, a piezoelectric buzzer element.
Kailitech acts as the organizer and the lead unit of the group standard review meeting of "General Specification for Laminated Piezoelectric Actuators" , which has been held in Wenzhou, Zhejiang Province from July 30 to August 3, 2020.
