Okay, we promise that we’re serious people when we’re not making Doctor Who references (but we are never not making Doctor Who references so…paradox?). This video shows how a speaker, once removed from its enclosure, can be used as either a speaker or a microphone, thus exhibiting the beauty of transduction! Specifically, this is a good example of how electromagnetic transduction can work in both directions (electrical to acoustic transduction and acoustic to electrical).
