How It Works
The speaker converts an electrical audio signal into sound using an internal electromagnetic mechanism. When an audio signal is applied to the speaker coil, the coil interacts with the permanent magnetic field and causes the diaphragm to vibrate. These vibrations produce audible sound waves.
The speaker should be driven using an appropriate amplifier or audio driver circuit. For microcontroller projects, avoid connecting the speaker directly to a GPIO pin unless the circuit is specifically designed for that purpose.
