SMARTPHONE SECURITY MASKING ENCLOSURE

摘要

The Mobile Phone/PDA Security Masking Enclosure is a sound insulated enclosure for use as a temporary storage location for cellular and other mobile devices in locations at which confidential and sensitive conversations and discussions are being conducted. A pink/white noise generating device within the enclosure generates a masking noise such that the cellular or other mobile devices inside the enclosure are unable to pick up or record conversations outside the enclosure.

主权项

1. A security noise masking box for securing and isolating devices comprising a microphone for detecting sounds in the surrounding environment, comprising:
(a) a box, comprising a sound absorbing material; (b) a box closure configured and dimensioned to close the box, the box closure comprising a closure sound absorbing material, the closure acoustic isolation volume between the closure walls containing said closure sound absorbing material; and (c) an acoustical noise generator arranged within the interior of the box, said acoustical noise generator matching the frequency content of the human voice and generating noise of an amplitude sufficient to drive circuitry receiving sounds detected by the microphone substantially into saturation, whereby when (i) a device with a microphone for detecting sounds from the surrounding environment is placed within the box, (ii) the box closure is closed and (iii) the acoustical noise masking circuitry is activated, the effectiveness of the device to receive useful sounds from the surrounding environment is substantially reduced.
