A
loudspeaker,
speaker, or
speaker system is an
electromechanical transducer that converts an
electrical signal to
sound. The term
loudspeaker can refer to individual transducer devices (otherwise known as
drivers), or to complete systems consisting of an
enclosure incorporating one or more drivers and
electrical filter components. Loudspeakers, just as with other electro-acoustic transducers, are the most variable elements in an audio system and are responsible for the greatest degree of audible differences between sound systems.
