Description:
PRIORITY CLAIM 
       [0001]    This application claims priority to U.S. Patent Application 62/333,728, filed on May 9, 2016, the entire contents of which are incorporated herein by reference and relied upon. 
     
    
     TECHNICAL FIELD 
       [0002]    The present disclosure relates to a personal multimedia pod that converts from an enclosable premium theater system with seating for one or more users to an unenclosed chair and/or to an output audio/video device capable of connecting (e.g., wirelessly connecting) to other audio/visual equipment. 
       BACKGROUND 
       [0003]    Traditional home theater systems are often impractical or disruptive due to the proximity of neighbors, cohabitants, or children. While headphones present one alternative in some situations, most headphones lack the premium sound quality and bass response available through a traditional home theater system. There is a need for a personal multimedia device that provides premium sound quality with the option to enjoy content privately. This need is especially notable as global population numbers swell and urban centers grow; devices consistent with the present disclosure could meet growing demand for personal space in an increasingly connected/urbanized world. 
       SUMMARY 
       [0004]    The present disclosure provides a convertible entertainment pod comprising a shell comprising an inner surface, an outer surface, and a closeable door; a base rotatably affixed to the outside surface of the shell; and a seating portion affixed to or integrated into the inner surface of the shell, wherein the convertible entertainment pod adopts a first, enclosed configuration when the closeable door is in a closed position. 
         [0005]    These and other embodiments are described in greater detail below in view of the several drawings.

         [0062]    In some embodiments, pod  100  has commercial uses such as sleep clubs, for example, by-hour rentals in public locations. Shopping malls, airports, and movie theaters are just some examples of other public locations where pod  100  can be located for short term (e.g., rental) use by a member of the public. 
         [0063]    In some embodiments, the pod  100  is able to provide noise cancellation. Noise cancellation allows sounds from a person&#39;s environment to be diminished or entirely eliminated during work or relaxation. Such sounds interfere with a person&#39;s ability to experience silence or other desired audio sounds. Other approaches to this problem include “sound masking,” in which white or pink noise is introduced to cover external sounds from the environment. Noise cancellation can be active or passive. Active noise cancellation requires the use of a power source. Passive noise cancellation includes the use of materials that absorb and block sound. The disclosure herein includes active noise cancellation.
