Abstract:
1. A protective cover for an electronic device, the protective cover comprising: a hard shell case having constituent rigid portions for enclosing an electronic device, wherein an intentional gap exists between a shell opening in the hard shell case and an acoustic opening of the electronic device when the electronic device is installed in the hard shell case; and an acoustic isolation mechanism disposed at least in the intentional gap and having an uncompressed thickness greater than the intentional gap, wherein the acoustic isolation mechanism comprises a compliant material that compresses when the electronic device is installed in the hard shell case, the compression of the compliant material minimizing shifting or rattling of the electronic device when the electronic device is installed in the hard shell case, and wherein the acoustic isolation mechanism comprises a passageway through which sound passes between the shell opening in the hard shell case and the acoustic opening in the electronic device when the electronic device is installed in the hard shell case, wherein, when the electronic device is installed in the hard shell case, the passageway of the acoustic isolation mechanism defines an acoustic channel between the electronic device and the hard shell case, and dimensions of the acoustic channel enhance acoustic properties of the protective cover.
