1. How does it work? Mechanical buzzers are devices that generate a buzzing or humming sound through mechanical vibrations. They consist of a coil, an armature, and a contact strip.   When an electrical current is applied to the coil, it creates a magnetic field. This magnetic field attracts the armature, which is a movable component attached to one end of a spring. As the armature is pulled towards the coil, it compresses the spring, storing potential energy.   Simultaneously, the contact strip, which is positioned near the armature, is pulled away from its normally closed position. This break in the electrical circuit interrupts the current flow, causing the magnetic field to collapse.   When the magnetic field collapses, the potential energy stored in the spring is released. This propels the armature away from the coil, causing it to strike the contact strip. This action closes the electrical circuit again, allowing current to flow through the coil, and the process repeats.   The rapid movement of the armature striking the contact strip generates vibrations, which produce the characteristic buzzing or humming sound.
