It’s essentially a targeted loudspeaker of sorts for your iDevices. The Annoyinator was conceptualized by the Henry, who is the son of Caleb Crome, the Kickstarter project’s listed creator.
Henry: Hey Dad, can you make a loudspeaker that aims only in one direction?
Dad: Well, sort of. Because of the way sound works, you need a very wide loudspeaker to make it directional and 'point' in some direction. For a reasonable size loudspeaker, you can make it very directional only at high frequencies.
Henry: Awesome. Can I make something that attaches to my iPod Touch and aims the sound from the 'Dog Whistle' app?
Dad: Yes, you can do that.
Henry: That's what I want to make!
After working on the design, the first Annoyinator was 3D printed. The Annoyinator recently reached its funding goal on Kickstarter.
