Lexicon Loudspeaker

A device that converts an electrical signal into sound. The electrical signal thereby contains an electrical equivalent of the sound to be generated. This distinguishes the loudspeaker from other electrically operated sound generators, such as sirens.

Loudspeakers can work according to different physical principles and have different designs. The most common type is the dynamic loudspeaker, which consists of an elastically suspended diaphragm moved by an electromagnetic drive. Such an assembly of diaphragm and drive is called a Loudspeaker Chassis. Real loudspeakers usually consist of several chassis of different design, because it is difficult to cover the entire desired frequency range with one chassis. The distribution of the signal to the different chassis is accomplished in such cases by a Crossover.
