The Dwarf 360 is a USB powered device, which produces omni-directional sound. In addition, it vibrates in order amplify the sound. The device could be useful in situations that require circular dispersing of sound, such as conference meetings.
This innovative, portable device connects to a computer via USB in order to produce audio (a 3.5mm jack is installed as well). According to its manufacturer, the device’s “tumbler” design is based on cutting edge technology, which enables the sound to travel in multiple directions at once. It was originally developed for the USA Navy, specifically for their radar systems. However, no elaboration was given about the military benefits this device provides. (Credit: Amazon)
