ACOUSTIC ISOLATION MECHANISM

摘要

A rigid removable case for a portable electronic device may have an acoustic isolation mechanism between the rigid removable case and an acoustic component on the electronic device. The acoustic isolation mechanism may be a compressible component that may provide an air seal between an interior surface of the removable case and an exterior surface of the electronic device. The acoustic isolation mechanism may be constructed of several different materials and several different manufacturing processes.

主权项

1. A protective cover for an electronic device, the protective cover comprising:
a hard shell case 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, wherein the acoustic isolation mechanism comprises a compliant material that compresses when the electronic device is installed in the hard shell case to minimize shifting or rattling of the electronic device, and wherein the acoustic isolation mechanism comprises a passageway through which sound passes between the shell opening in the hard shell case and an 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, the dimensions of the acoustic channel configured to enhance the acoustic properties of the protective cover.
