At least part of the silencer faces or forms the outer side. The silencer has a front facing the person, a rear, and a silencer structure. At least part of the silencer structure extends between the front and the rear. The silencer includes at least one of (a) a vibroacoustic region and (b) at least in sections, a fibrous surface texture at the front with a plurality of protruding fibrous material sections.

A privacy protection device for use with a mobile electronic device. The privacy protection device is configured to block the cameras and microphones of the mobile electronic device when not intended for use. The privacy protection device comprises a housing with a plurality of apertures built in for access to the cameras and microphones of the mobile electronic device when in place. A rear camera aperture cover is configured to slidably engage a rear camera aperture to cover the aperture when the rear camera is not needed. A front camera aperture is configured to slidably engage a front camera aperture to cover the aperture when the front camera is not needed. A bottom aperture cover is configured to hinge or snap in place to cover a bottom aperture when the microphone is not needed.

The present application discloses a portable electronic device. The device includes a case; a camera lens fixed to the case; a sound generator attached to the case for producing sounds; and a central process unit and a circuit system for providing controlling current to the camera lens. The camera lens includes a side wall and a lens holder moveable relative to the side wall. The lens holder is driven to a predetermined position farther away from the case than an initial position, when the sound generator is producing sounds. The present application further provides a method for eliminating noise by applying controlling current to the lens holder to move the lens holder to a position farther away from the case for avoiding collision between the case and the lens holder.

A flexible method to provide a variety of value-added coatings to a piece of jewelry or a group of jewelries is disclosed. Atomic Layer Deposition (ALD) and Molecular Layer Deposition (MLD) technique is implemented to deposit a layer of conformal coating on intended jewelry surfaces, including both exterior and interior surfaces, to enhance a vast majority of process-driven or end of use driven properties. The coating compositions include dielectrics material, metals, organic materials or organic-inorganic hybrid materials. The method steps of forming a layer of coating are straightforward and can be tailed to different purposes.

An electronic device according to various embodiments of the present disclosure may include: a printed circuit board including one face; at least one electronic component mounted on the printed circuit board; and a conductive shield can structure attached to the one face of the printed circuit board while surrounding the at least one electronic component. The conductive shield can structure may include: a first conductive plate including a first edge portion, a second edge portion spaced apart from the first edge portion, and a third edge portion extending between the first and second edge portions, and in top view of the one face of the printed circuit board, including a first flat portion parallel to the printed circuit board and constructing a recess together with the first to third edge portions; a second conductive plate including a fourth edge portion extending substantially parallel to the third edge portion, and in top view of the one face of the printed circuit board, including a second flat portion to be attached to the first flat part while at least partially overlapping the first flat portion; a first side portion extending along the first edge portion and substantially vertical to the first flat portion; a second side portion extending along the second edge portion and substantially vertical to the first flat portion; and a third side portion bent from the fourth edge portion while surrounding the third edge portion, and substantially vertical to the first flat portion.

Headphones includes a pair of cups, each housing a speaker to be positioned over an ear of a user, a microphone, a processor, an actuator to move a member of at least one of the cups to uncover at least a portion of the ear of the user to expose the user to ambient sound, a user control to active a training mode of the headphones in which the processor operates the microphone to record relevant sounds occurring when the training mode is activated, the processor to subsequently analyze ambient sounds external to the headphones that are received by the microphone and compare those ambient sounds to the recorded relevant sounds and the processor to selectively activate the actuator to uncover at least a portion of the ear of the user to expose the user to ambient sound in response to determining that the ambient sounds match the relevant sounds.

In accordance with some embodiments, an apparatus for privacy protection includes a housing arranged to hold a second device, a local communication device at least partially supported by the housing, and a controller, where the apparatus is associated with a radio frequency (RF) power detector. The RF power detector monitors energy emitted from one or more antennas of the second device in response to determining that the second device indicates that the second device has transitioned from a first mode of operation to a second mode of operation. The apparatus further establishes a communication channel between the apparatus and the second device, and obtains, through the communication channel, a communication status of the second device. The apparatus can then report compromise of the second device upon determining that a discrepancy between the communication status and the energy emission.
