According to researchers, the compound annual growth rate (CAGR) is estimated at 0.4%. This work should be registered within the next four years. The piezo buzzer component industry recently released a marketProduct News February 19, 2020
- The principle of ultrasonic rangingThe 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.Product News March 04, 2023
- Points to note when choosing an ultrasonic ranging sensorThe principle and structure of modern ultrasonic ranging sensors vary greatly. How to select a sensor reasonably according to the specific measurement purpose, measurement object and measurement environment is the first problem to be solved when performing a certain amount of measurement. After theProduct News May 09, 2020
- Why buzzer has noiseWhen the sound of the buzzer is not a crisp and simple hum, we will call it a murmur or a broken sound. The cause of the buzzer noise can be divided into two possibilities.First, there are problems with the way of using:The voltage to the buzzer is too high: the diaphragm hits other parts inside the
- Mechanism of active buzzer soundStructure of piezoelectric diaphragmThe piezoelectric sound element must have a piezoelectric diaphragm.This is a simple structure in which a piezoelectric ceramic adheres to brass or nickel alloy metal plate.Mechanism of producing sound for piezo diaphragmsWhen a voltage is applied to the piezoelecProduct News September 05, 2019
