In what year was the first experimental moving coil speaker invented?

The first experimental moving coil speaker was invented in 1898 by Emil Berliner. This innovation marked a significant development in sound technology, as it utilized a coil of wire attached to a diaphragm that could create motion when an audio signal was applied. This design laid the foundation for many modern loudspeakers, leading to improvements in sound reproduction quality. Berliner’s pioneering work in this area would eventually contribute to the evolution of audio devices, influencing various aspects of sound technology in both consumer and professional audio equipment. The other years mentioned do not correspond to this invention, as significant advancements in audio technology were occurring around this time, but none match the timeline of Berliner’s invention.
