a piece of equipment that makes sounds louder, used for playing music, etc.
A loudspeaker is a device that converts electrical signals into sound. It consists of a speaker driver that moves air to create sound waves, which are then projected outwards. Loudspeakers are used in various settings, such as in home audio systems, public address systems, and theaters, to amplify and distribute sound. They come in different sizes and designs to suit different needs, from small portable speakers to large, powerful ones for concerts and events.
