What are the parts of a buzzer?

A buzzer typically consists of several key components: a diaphragm, which vibrates to produce sound; a coil, which creates a magnetic field when an electric current passes through it; and a housing that encloses these parts and helps amplify the sound. Some buzzers may also include a piezoelectric element that generates sound through mechanical stress. Additionally, there is often a power source and circuitry that control the operation of the buzzer.
