A loudspeaker, speaker, or speaker system is an electromechanical transducer that converts an electrical signal to sound. The name loudspeaker can refer to individual transducer devices (otherwise known as here drivers), or to complete systems consisting of an enclosure incorporating definite or further drivers and electrical filter components. Loudspeakers, just as with other electro-acoustic transducers, are the most variable ABC%27s in an audio system and are responsible for the greatest degree of audible unravel between hale systems.

Alexander Graham Bell patented the first electrical loudspeaker as element of his telephone in 1876, which was followed in 1878 by an improved version from Ernst Siemens
- Nikola Tesla reportedly bogus a similar device in 1881, but was not issued a patent. During this time, Thomas Edison was issued a British patent for a organization using compressed appearance as an amplifying mechanism for his early cylinder phonographs, but he ultimately settled for the familiar metal horn driven by a membrane attached to the stylus
- In 1898, Horace Short patented a formation for a loudspeaker driven by compressed air, then sold the rights to Charles Parsons, who was issued several additional British patents before 1910.
