Sound amplifying cases for electronic devices

摘要

A sound amplifying case for an electronic device includes a shell that receives and secures the electronic device on a front side of the shell. The shell has a sound channel formed therein which receives sound from the electronic device at an inlet sound port on the shell front side, amplifies the redirected sound, and directs the amplified sound to an outlet sound port on a back side of the shell. The case includes a folding cover attached at one end to the shell back side and extends around one edge of the shell to a free end. With the case in an open configuration, the cover folds between the attached end and the free end forming an acoustic chamber between the cover and the rear side of the shell. The chamber receives the amplified sound from the outlet sound port and further amplifies/redirects it out of the acoustic chamber.

主权项

1. A sound amplifying case for an electronic device secured to the case, the case comprising:
a shell constructed to receive and secure the electronic device on a front side of said shell, said shell having a sound channel formed therein constructed to receive sound from the electronic device at an inlet sound port on said front side of said shell, amplify said redirected sound, and direct said amplified sound to an outlet sound port on a back side of said shell; and a folding cover attached at one end thereof to said back side of said shell and extending around one edge of said shell to a free end, wherein when said case is in an open configuration said cover is constructed to fold between said attached end and said free end forming an acoustic chamber between said cover and said back side of said shell, and wherein said acoustic chamber receives said amplified sound from said outlet sound port and further amplifies and redirects said received sound out of the acoustic chamber, wherein the cover includes a front portion and a back portion foldable along a spine between said front portion and said back portion, said front portion configured to conceal said front side of said shell when said case is in a closed configuration and configured to reveal said front side of said shell when said case is in said open configuration, and wherein in said open configuration said shell is retained between said front portion and said back portion at an angle with respect to said front portion, wherein said sound channel is raised with respect to a surface of said back side of said shell, and wherein said attached end of said back portion of said cover includes a first part extending from said raised sound channel and includes a second part extending from said surface of said back side of said shell.
