The modular concept hits speakers in the shape of SparkBlocks, an audio system consisting of cube-shaped components users attach to each other order to build an audio setup as simple or elaborate as desired.
Holding a SparkBlocks system together is the MainBlock, a portable speaker with 4-hour battery life. Users can use the MainBlock as a regular standalone speaker, but the addition of other components (such as the self explanatory Tweeter and Battery Blocks) add to its capabilities.
One can even add "smart" capabilities through the SmartBlock, a Linux-based touchscreen module able to handle Bluetooth and wifi connectivity, music control, smartphone notifications and even music apps. Other modules can charge mobile devices, clip the system to bicycles or even add LED lighting.
