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 that is dimensioned to receive a predetermined electronic device and wherein air is not transferred into or out of the volume; and
wherein when the main housing and the lid when joined together forms at least one membrane, wherein air trapped within the air and water tight volume transfers acoustic energy from a sound source within the case to said at least one membrane wherein the at least one membrane is impermeable to air and that vibrates in response to an air pressure differential so that sound is operable to be transmitted to an exterior of the case, and wherein the main housing joined with the lid defines an air piston wherein the lid includes a microphone port having a membrane assembly attached thereon the membrane assembly being non permeable to air and water, and the membrane assembly being compliantly mounted with respect to the microphone port allowing the membrane assembly to freely vibrate.

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 an air and 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 that is dimensioned to receive a predetermined electronic device and wherein air is not transferred into or out of the volume; and wherein when the main housing and the lid when joined together forms at least one membrane, wherein air trapped within the air and water tight volume transfers acoustic energy from a sound source within the case to said at least one membrane wherein the at least one membrane is impermeable to air and that vibrates in response to an air pressure differential so that sound is operable to be transmitted to an exterior of the case, and wherein the main housing joined with the lid defines an air piston and including an electronic device positioned with the air and water tight volume, and wherein the electronic device and lid define an air gap and the lid is formed of a material that is operable to function as an acoustic membrane transferring sound from the electronic device within the air and water tight volume to an exterior of the case.
