What are working principle of PIEZO ACTIVE BUZZER WITH PIN

A piezo active buzzer with a pin operates on the principle of the piezoelectric effect to generate sound. The working principle can be explained in the following steps:
Piezoelectric Material: The active buzzer contains a piezoelectric material, typically a ceramic disc or crystal, sandwiched between two metal plates. This material has the property of generating an electric charge when subjected to mechanical stress or pressure.
Voltage Applied: When a voltage is applied to the buzzer, the electric field created within the piezoelectric material causes it to deform or change shape.
Mechanical Deformation: The applied voltage causes the piezoelectric material to undergo a mechanical deformation, either expanding or contracting depending on the polarity of the voltage.
Vibrations: The deformation of the piezoelectric material results in rapid vibrations or oscillations. These vibrations propagate through the material, creating mechanical waves.
Sound Generation: As the piezoelectric material vibrates, it causes the surrounding air molecules to vibrate as well. This vibration of air molecules creates sound waves, which we perceive as sound.
Frequency Control: The frequency of the sound produced by the active buzzer can be controlled by the voltage applied to the piezoelectric material. By changing the frequency of the voltage, the buzzer can generate sound at different frequencies.
Amplification: In some cases, an internal driving circuit within the active buzzer amplifies the voltage signal to ensure sufficient vibrations and sound output.
Electrical Connection: The pin or pins on the buzzer provide electrical connections to the piezoelectric material and the driving circuit, if present. The pins can be soldered or connected to a circuit board to establish the electrical connection.
By applying an appropriate voltage and utilizing the piezoelectric effect, the piezo active buzzer with a pin converts electrical energy into mechanical vibrations, which in turn generate audible sound waves. The pin serves as a means to provide electrical connectivity and mechanical stability to the buzzer.
