1. A protective case for an electronic device comprising:
- a main housing;
a lid;
the main housing and lid removably joined to define an air and water tight volume receiving an electronic device;
at least one air cavity defined by the device inserted into the volume, the air cavity located between the device and the main housing or lid;
at least one membrane positioned on the main housing or lid, wherein the membrane is compliantly mounted and is impermeable to air and sized to vibrate and translate acoustic energy from a sound source into vibrational energy without significant attenuation allowing sound waves to be generated on an opposing side of the membrane either internal or external to the volume.

Abstract
A protective case for an electronic device includes a main housing and a lid. The main housing and lid are removably joined to define a water tight volume receiving an electronic device. Air trapped within the protective case transfers acoustic energy from a sound source within the case to at least one membrane wherein the membrane vibrates in response to an air pressure differential transmitting sound to an exterior of the case.

22. A protective case for an electronic device comprising:
-
a main housing; a lid; the main housing and lid removably joined to define an air and water-tight volume receiving an electronic device; at least one air cavity is formed of a foam, rubber or elastomer material that seals and defines an air volume between the device and any of the lid or main housing in which the air cavity is used to isolate or channel sound to or from a specified area of a microphone or speaker of the device.
