What is a Buzzer ? An audio signaling device like a beeper or buzzer symbol may be electromechanical or piezoelectric or mechanical type. The main function of this is to convert the signal from audio to sound. Generally, it is powered through DC voltage，then produce sound and used in timers, alarm devices, printers, alarms, computers, etc. Based on the various designs, it can generate different sounds like alarm, music, bell & siren.The sound pressure level is a crucial parameter for the ... In this blog, we will delve into the science behind buzzers, exploring their inner workings, diverse applications, and historical origins. A buzzer or beeper is an audio signaling device. It generates sound in a frequency range of 1 to 7 kHz as an audio indication. In this frequency range, the hearing threshold is maximum. Therefore, the sound of a buzzer is so piercing that it is noticeable even in a highly noisy environment. The buzzers /beepers are generally used as sound alarms. In many applications, they are used to give an audio indication in response to some action or event. A buzzer can be used to produce the sound of a ...
