A lens selector for selectively exposing one camera lens and covering other camera lenses of a cell phone or the like is shown and described. The lens selector comprises a base which grips the cell phone and a lens cover movable between two or more positions. The lens cover may slide along the base when moving between positions. An arm resiliently biased into an engaged positions may lock the lens cover into a selected position on the base. The lens selector may substantially cover that side of the cell phone having lenses, and may grip edges of the cell phone. The lens selector may include a socket for centering an associated cell phone with respect to an optical device such as a spotting scope, so that the cell phone may capture images visible through the scope.

There is disclosed a photography housing (10) for a portable electronic device (56) having an image sensor (58). The housing has first (12) and second (14) housing components defining at least a partial enclosure for receiving a portable electronic device, the first and second housing components being movably connected to one another, such that an internal dimension of the at least partial enclosure can be altered to releasably fit a dimension of the portable electronic device (56) inserted therein. The housing (10) comprises a user input device (22, 24, 26, 28) for controlling the operation of the image sensor (58) during use of the photography housing. The housing may provide a professional photography housing for a mobile telephone, e.g. providing ergonomic shutter control and photographic function selection via wireless communication with the mobile telephone.

A selfie mirror for smartphones includes a combination of a mirror and a ferromagnetic metal plate arranged therebelow and connected to the mirror, as well as means for fixing the arrangement comprised of the mirror and the ferromagnetic metal plate to a smartphone or a smartphone case. The mirror and the metal plate may be mechanically connected to each other by means of an adhesive foil or adhesive layer arranged therebetween, or they may be mechanically held together and/or enclosed by a frame surrounding them around their periphery.

An improved wireless communications earplug for use with a magnetic field transmitter. The wireless earplug has a receiver made of a coil of wire on a magnetic bobbin, mounted in close proximity or in contact with a magnetic case of a speaker. The magnetic case of the speaker serves to increase the magnetic flux through the receiver and improves the efficiency of the earplug. The speaker is acoustically coupled to an eartip, and the earplug may be molded into a custom earplug body.
