A loudspeaker was usually a type of electronic device that made use of a microphone to make someone's voice louder. Often times such devices were connected to an intercom system, which allowed one to radio someone in another location.

There was a loudspeaker located in Jor-El's laboratory. On the occassions that the Drygur Molium of the Kryptonian Science Council paged him, his voice could be heard over the loudspeaker.[2]
