Buzzers can be divided into piezo buzzers, magnetic buzzers and mechanical buzzers. This is classified according to how the buzzer works. Active buzzers can be used for different purposes, such as alarm clocks or timers. It can also be used for home appliances. The active buzzer market has rapid

There are two types of piezo buzzer, active buzzer and passive buzzer, each with its advantages. In this article, we will discuss the various benefits of using an active buzzer.

Piezo buzzers are also known as piezoelectric materials, and their shape can change, especially when exposed to various electric fields. A piezo buzzer material has an atom. The atom usually has a central nucleus made of multiple neutral charges, such as the positive charges. These charges are calle

A piezo buzzer refers to an electronic device that is commonly used in various field fields to produce sound. For example, the buzzer in question is frequently found in call bells, computer systems, and in vehicles as reversing indicators, among various other areas. There are two types of piezo bu

Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals, usually electrical signals. It is an important branch of sensor products and accounts for a large proportion in the entire sensor industry. Ultrasonic sensors are widely used such as:Liquid level measurement: s

The sound wave frequency that human ears can hear is 20HZ～20KHz. When the frequency is higher than 20KHz, the human ear cannot hear it. Therefore, we call the sound wave with a frequency higher than 20KHz "ultrasonic wave".Ultrasound has a strong directivity and travels a long distance in the air.
