All of the options listed can be considered electromagnetic devices to some extent, but the most direct answer would be **a loudspeaker**.
A loudspeaker specifically converts electrical energy into sound energy using electromagnetic principles. It uses an electromagnetic coil and a magnetic field to create motion in the speaker cone, producing sound.
However, it's worth mentioning that a wireless radio, a television, and a computer also rely on electromagnetic principles to function, as they use electromagnetic waves for communication and operation.
