Who made speakers?

Speakers were developed through the contributions of various inventors and engineers over time. Early advancements in loudspeaker technology can be attributed to figures like Johann Philipp Reis, who created a primitive version in the 1860s, and later, Thomas Edison and Emile Berliner, who further advanced sound reproduction. The modern dynamic speaker design, which utilizes a voice coil and magnet, was perfected by engineers like Edward W. Kellogg and Chester W. Rice in the 1920s. Today, numerous companies and innovators continue to produce and enhance speaker technology.
