    How do piezoelectric buzzers work?

    A piezo buzzer is a sound producing device.The main working principle is based on the theory that, whenever an electric potential is applied across a piezoelectric material, a pressure variation is generated. A piezo buzzerconsists of piezo crystals in between two conductors.When a potential differe

    What is the 1/2 duty square wave?

    If the user uses a passive piezoelectric buzzer or a passive electromagnetic buzzer, it is recommended to use 1/2 square wave in the input voltage and frequency conditions. Why use it? Because this condition can The buzzer (buzzer) inside the buzzer achieves the highest amplitude, which means that t

    Buzzer Frequency and Buzzer SPL

    A buzzer sound is produced by vibrating objects which have a certain frequency of sound waves. Frequency refers to the number that contains the consecutive cycles per second. Buzzer's resonant frequency is 2-4KHZ. Buzzer's resonant frequency refers to the recommended maximum, and sound pressure cons

    Possible Reason that the Buzzer Has Noise

    When the sound which the buzzer generates is not a clear beep sound, we call it noise or broken sound. There are two possible ways to cause the noise.Improperly used If the voltage we input is too high, the diaphragm will easily touch other components, which causes the noise.When we set the wrong fr
