Abstract

A waterproof protective case can include a front portion with a cavity configured to receive a personal electronic device and a back portion configured to attach to the front portion to form the protective case. The back portion can include an overmolded gasket or a form-in-place gasket extending around a perimeter of the back portion. The front portion can include a mating surface extending around a perimeter of the cavity. The mating surface of the front portion can be configured to seal against a flexible sealing surface of the gasket when the back portion is attached to the front portion to provide a liquid-tight seal.

9. The protective case of claim 1, further comprising a foam layer adhered to the inner back surface of the back portion, wherein the foam layer is configured to contact a back side surface of the personal electronic device when installed in the protective case.

10. The protective case of claim 1, wherein the inner left side surface, the inner right side surface, the inner bottom surface, and the inner top surface of the cavity in the front portion each comprise a plurality of overmolded protrusions configured to contact a surface of the personal electronic device when the personal electronic device is installed in the cavity.

11. The protective case of claim 1, wherein the front portion further comprises a speaker opening covered with an acoustic membrane and a sound isolator extending around the speaker opening, wherein the sound isolator is adhered to an inner surface of the acoustic membrane and is configured to surround and isolate a speaker on a front surface of the personal electronic device.
