Today, most of the loudspeakers are big in size due to their large diaphragm. Hence, they limit their portability. The idea is to replace the conventional diaphragm with a more elastic diaphragm so that it can be compressed or stretched, without altering the sound and vibration quality, thus making it portable.
Its circular radius is same as of a compact disc i.e. 60mm, and height is 20mm (when closed).
It has in-built :
MMC card slot
Battery status indicator
