USBFever has launched a new speaker system for iPods or MP3 players in the form of the Sonar Speaker. It is a round device that uses vibration to produce sound and can be used on many surfaces including wood, glass and stone. Available in red or black, the SONAR speaker produces a lower-tuned frequency response of 100Hz–18Khz. You can buy the SONAR speaker for $35. Each purchase comes with a USB cable and a replacement plastic cushioning blade. Watch the video after the jump to get more details.
