What is inside a speaker?

A speaker typically contains several key components: a diaphragm, which vibrates to create sound waves; a voice coil, which interacts with a magnetic field to produce movement; a magnet, providing the necessary magnetic field; and a frame or enclosure that holds these parts together. Additionally, some speakers may include a crossover network to manage different frequency ranges, directing them to appropriate drivers like woofers and tweeters. Together, these components work to convert electrical signals into audible sound.
