Amplifear iPad Attachment Amplifies Simply, Effectively

We’ve said it before and we’ll keep hammering the point in: it’s the simpler things that we value most. The Amplifear is an elegant solution for amplifying the sound coming out of your iPad. Sure, it looks like a Mickey Mouse ear, but the ABS plastic device is reported to do a really great job at boosting those high frequencies, giving you a crisper and generally louder sound. You just clip it on or off, no installation required.

Best of all, it’s cheap: $15, currently on Kickstarter, as a fully funded project.

Soundlazer Focuses Sound, Much Like A Laser Focuses Light

Parametric speakers are speakers that are very good at focusing sound, so that its beam is narrow and can be aimed at a particular target. The technology has been around for quite a while, but not until recently has any effort been made to construct them out of modern electronic components. The Soundlazer is, well, just that. It’s a small set made up of 39 piezo ultrasonic transducers, an Analog Devices ADAU1701 Digital Signal Processor and lots of other surface mount parts. And it does just one thing: focus a beam of sound so that only your target can hear it and no one else.

What’s this good for? Let’s see: pranks! You just plug it into your music player and make them hear things only they can hear. You know that’s absolutely worth the $175 (without the red aluminum case) or $250 (with).

Right?
