Creative recently unveiled the TravelSound for iPod nano 3G, a new compact speaker system with a built-in rechargeable battery. The system features four independent micro drivers and a digital amplifier, and Creative claims that it puts out more sound than comparably priced larger systems. The TravelSound charges through USB 2.0, and can play for 15 hours. Creative is currently only selling the system in Singapore for $130 (~$100 USD).

Creative says that the TravelSound can be used as a dock for the Nano, allowing users to transfer songs between the iPod and computer without removing it from the enclosure. The TravelSound also tilts the iPod to make it easier to watch video on the Nano's screen.
