wherein a signal produced by the second auxiliary microphone can be used to cancel the mechanical noise from the signals produced by the auxiliary microphone.
10. The apparatus of claim 1 , wherein the lens shutter comprises an opaque coating or material.
11. The apparatus of claim 1 , wherein the lens shutter comprises an electro-optical element.
12. The apparatus of claim 1 , comprising a switch configured to concurrently activate and deactivate the lens shutter, the generator, the auxiliary microphone, and the processor.
13. The apparatus of claim 1 , wherein:
the electronic device comprises a plurality of microphones and a plurality of cameras; and
the structure is configured to support a plurality of the lens shutters and a plurality of the generators.
14. The apparatus of claim 1 , wherein the generator is configured to generate air pressure.
15. The apparatus of claim 1 , wherein the generator is configured to generate an electric force.
16. The apparatus of claim 1 , wherein the generator is configured to generate a mechanical force.
17. An apparatus for use with an electronic device having a microphone, a camera, and a wireless communication facility, the apparatus comprising:
a structure configured to detachably couple to the device, the structure configured to support a plurality of components comprising:
a lens shutter configured to obscure a lens of the camera when engaged or activated;
a generator configured to generate a force that acts on the microphone of the electronic device and renders the microphone unresponsive to a user's voice sounds; and
an auxiliary audio system configured to facilitate secured conversations between the user and a remote device during a time in which the generator renders the microphone of the electronic device unresponsive to the user's voice sounds.
18. The apparatus of claim 17 , wherein the auxiliary audio system comprises:
an auxiliary microphone; and
a processor coupled to at least the auxiliary microphone.
19. The apparatus of claim 17 , wherein:
the structure is configured to support a user actuatable switch operable in an activation state and a deactivation state;
the switch activates the lens shutter, the generator, and the auxiliary audio system when in the activation state; and
the switch deactivates the lens shutter, the generator, and the auxiliary audio system when in the deactivation state.
20. The apparatus of claim 17 , wherein the auxiliary audio system is configured to encrypt audio signals received from the user.
21. The apparatus of claim 20 , wherein the auxiliary audio system is configured to transmit the encrypted signals to the electronic device for transmission through the wireless communication facility.
