         12 . The sub-tragus ear unit according to  claim 1 , wherein the sub-tragus region is a portion of space that is swept out by the underside of a tragus as the tragus is moved by a force is applied to the tip of the tragus in a direction toward the back of a concha. 
     
     
         13 . The sub-tragus ear unit according to  claim 1 , wherein the sub-tragus region is a volume of space that is swept out by a shape, pivoting at a fulcrum, toward the concha, wherein:
 the shape is defined as the portion of the inside of the tragus which is not in contact with, or a portion of, the ear canal; and   the fulcrum is a boundary between the shape and the opening of the ear canal.   
     
     
         14 . The sub-tragus ear unit according to  claim 1 , wherein the sub-tragus region is a volume of space that is swept out by a shape, pivoting at a fulcrum, toward the concha, wherein:
 the shape is defined as the portion of the inner surface of the tragus that is within 4 cm of the opening to the ear canal, and   the fulcrum is a boundary between the shape and the opening of the ear canal.   
     
     
         15 . The sub-tragus ear unit according to  claim 1 , wherein the sub-tragus region is a volume of space between the tragus and the back of the concha which is within 4 cm of the opening to the ear canal.
