Audio Recording Using A Cup

Did you know that we can record audio using a cup? Well, it’s a little more than a cup, as dusttodigital shared a video of their setup on Instagram. The cup serves as the microphone that takes in the sound one wishes to record. Head over to their post to see the full setup!

Audio recording via cup or by the vibration sensor attached to the cup? It's the vibration sensor that makes it a microphone. Admittedly the enclosure makes it a better one - but it's still dependent upon the vibration sensor in a very fundamental way. There are much better "hacks" around. You can make a speaker out of a coin for example.
