US Patent 9260863 Dynamically responsive acoustic tuning envelope system and method

A dynamic responsive acoustic tuning envelope system that includes a movably connected set of cells, each possessing sound reflecting, sound absorbing, and/or electro-acoustic properties, and which are assembled according to the principles of rigid origami. So configured, the system is capable of both localized surficial deformation to alter the material surface exposure, transform its textural profile, and alter the enclosed volume of space in a single material envelope, thereby tuning the acoustics of the environment in which the system resides.
