Working Principle of Piezo buzzerThe piezo buzzers use piezoelectric materials. Piezoelectric materials create electricity when stress is applied, and become stressed when electricity is applied.The piezo element is to stick the piezoelectric material on the metal sheet. When an alternating voltage

The working principle of traditional magnetic active buzzer is electromagnetic induction. The active buzzer has its own oscillation circuit, and the customer only needs to use DC voltage.The working principle of the IC magnetic buzzer is that the chip oscillates a square wave signal with a fixed fre

In daily production and life, ultrasonic ranging sensors are mainly used in car reversing radar, robot automatic obstacle avoidance walking, construction sites, and some industrial sites such as liquid level, well depth, pipeline length and other occasions that require automatic non-contact ranging.

Ultrasonic sensors are sensors developed using the characteristics of ultrasound. Ultrasonic ranging sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). Ultrasound is a mechanical wave with a vibration frequency higher than 20kHz. It has the ch

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.
