Korg's Cliphit turns everyday objects into an impromptu drum kit

Many of us find ourselves tapping our fingers on desks or tabletops at any and every opportunity. It doesn't matter whether or not we've ever actually held a drumstick, if we have a rhythm in our head and a hand free we'll tap out a beat on whatever surface is within reach. We have already seen attempts to turn this from an annoying habit into a way of making something approaching real music, such as the Wavedrum and the TableDrum, but Korg has now upped the ante with Cliphit.

Four years ago, we first heard about how Korean scientists had proposed using sound to charge mobile phones. They explained that it could be done via a piezoelectric effect, in which zinc oxide nanowires converted sound-caused vibrations into electricity. At the time, the researchers couldn't generate enough of a current to actually charge a phone. Now, however, scientists from Nokia and Queen Mary University of London (QMUL) have succeeded in doing so. Read More

Acoustic bottle beams hold promise for acoustic imaging, cloaking and levitation

By - August 5, 2014 2 Pictures
Using a technique that has possible applications in acoustic cloaking, sonic levitation, ultrasonic imaging, and particle manipulation, scientists at the University of California Berkeley claim to have produced a "bottle" beam of acoustic energy in open air that can precisely redirect sound waves. Able to bend these waves along set trajectories without the need for waveguides or other mechanical assistance, the bottle beam is also able to flow around objects in its path while maintaining its shape.
