loudspeakers
Public address equipment
Loudspeakers are devices that convert electrical signals into audible sound, projecting it across a space.
The term covers everything from concert speakers to the small drivers in phones and laptops.
Public address systems use loudspeakers to broadcast announcements: The loudspeakers crackled with the boarding call.
Often shortened to speakers.
