Check out the new portable speaker design by CRE8 Design. The speaker has been designed in such a way as to accomodate Apple’s Smart Cover or other similar devices on the triangular space of the speaker. The speaker can magnetically attach itself to the Smart Cover and can be rolled up within it. The speaker can be pushed back into the body when not in use.
The iPad Sound Prism has been specifically desgined for iPad, but it can also work with other devices due to Bluetooth connectivity. For now its just a concept design, more info is yet to be available.
