This article is about an acoustic device loudspeaker, and the widely used types of loud speaker in details.
Loudspeaker is an electrical transducer which converts electrical energy into acoustical energy. First a microphone converts incidence sound waves into simple electric voltage oscillation. Then this electrical signals made by microphone amplifier and then it is converted back into sound vibrations using a loudspeaker. There is some property that every good loves you should have that is a high efficiency, frequency independent response over the entire audible range, no harmonic distortion, non directional output low cost small size, longer durability.
