ACOUSTIC ISOLATION MECHANISM WITH MEMBRANE

摘要

A removable case for an electronic device may have an acoustic isolation mechanism between the removable case and an acoustic component on the electronic device. The acoustic isolation mechanism may be a compressible component that may provide an acoustic seal between an inner surface of the removable case and an exterior surface of the electronic device, and may include a waterproof acoustic membrane. The waterproof membrane prevents the entry of water while reacting to sound pressure changes to acoustically couple the electronic device with sounds outside the case. 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 case for enclosing the electronic device, the case having an inner surface, an outer surface, and a sound aperture in the case proximate an acoustic opening of the electronic device when the electronic device is installed in the case; and an acoustic isolation mechanism disposed on the inner surface of the case proximate the acoustic opening of the electronic device, wherein the acoustic isolation mechanism comprises
an interior face oriented towards an interior of the case and an exterior face oriented towards an exterior of the case, the exterior face contacting the inner surface of the case,at least one acoustic channel extending from the interior face to the exterior face of the acoustic isolation mechanism that acoustically couples the electronic device and the sound aperture, andat least one acoustic membrane that spans a cross-section of the at least one acoustic channel, andwherein the acoustic isolation mechanism is molded from a waterproof elastomer.
