11. The electronic device of claim 1 , further comprising a transceiver, wherein the one or more processors, responsive to executing the computer instructions, are configured to perform operations comprising transmitting at least one parameter of the biometric signal to another device operatively coupled to the electronic device, and analyzing the at least one parameter of the biometric signal, wherein the analyzing is done either locally or remotely to the electronic device or both.
12. The electronic device of claim 1 , wherein the electronic device is an earpiece having a speaker that is configured to provide an audible message to a wearer of the earpiece responsive to identifying a parameter of the biometric signal.
13. The electronic device of claim 1 , further comprising:
an ear canal microphone port that terminates distal to the balloon at a location internal to where the balloon contacts the surface of the ear canal, wherein sounds within the ear canal are ported to the ear canal microphone.
14. The electronic device of claim 13 , further comprising:
an earpiece body that extends outside the ear canal;
an earpiece body extension that extends distally from the earpiece body and internally toward to the ear canal; and
wherein the balloon is coupled to the earpiece body extension.
15. The electronic device of claim 13 , wherein the extension is configured to extend beyond the balloon into the sealed or partially sealed ear canal.
16. The electronic device of claim 1 , wherein the balloon the balloon has a shape of one of a prolate spheroid, a prolate ellipsoid, or an ovular shape having a narrow-width or a narrow profile edge.
17. The electronic device of claim 1 , wherein the balloon is filled with a medium of non-Newtonian fluid medium.
