Loudspeaker, an Uncommon card

The card carries these facts from its Wikipedia article.

• The speaker driver is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound.
• The driver is a linear motor connected to a diaphragm, which transmits the motor's movement to produce sound by moving air.
• An audio signal, typically originating from a microphone, recording, or radio broadcast, is electronically amplified to a power level sufficient to drive the motor, reproducing the sound corresponding to the original unamplified signal.
