An apparatus includes a frame, a left temple, a right temple, a left end piece, a right end piece, a left hinge, and a right hinge. The frame includes a left side and a right side, and the frame may support a lens. The apparatus frame that improves vision may be tilted to supply the lenses at varying angles and lock into place via a latching mechanism. The effect of the tilted lens provides significantly increased clarity and definition of vision, with no expensive custom lenses or magnification.

Embodiments of thin eyeglasses are provided. The eyeglasses comprise first and second lens connected by a resilient bridge. The eyeglasses comprise a first and second ear piece connected to the first and second lens by a first and second hinge. One lens can be rotated about the hinge and over the other lens to place the eyeglasses in a compact configuration.

The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.

A hinged connection between first and second members (24, 25) which makes use of a fixation pin (1). The fixation pin (1) has a first configuration which enables the pin to be inserted through a first hole in a first member (24), through an aligned intermediate hole in the second member (25) and through an aligned second hole in the first member (24). The fixation pin (1) does not have a screw thread on its exterior surface. The fixation pin (1) after it has been inserted is subject to a treatment which changes it to a second configuration, or the fixation pin spontaneously changes, while it is being inserted through the holes or immediately thereafter, to a second configuration. In the second configuration, part or all of the fixation pin contacts the wall of at least one of the holes, so that the first and second members are connected together at a hinged connection. The invention is particularly useful when the hinged connection is part of an eyeglass assembly, wherein the temple member or the frame member is the first member (24) and the other is the second member (25).

Process for assembling an elastic hinge for eyeglass frames comprising a first articulation provided with a head with a first hole, a second articulation having two shoulders provided with second holes, and a pin having a stem provided with a thinned final portion. The process provides for inserting the head of the first articulation between the two shoulders of the second articulation with the first hole of the first articulation non-aligned with respect to the second holes of the second articulation, an opening thus remaining between such holes. A step for inserting the pin is provided, during which the thinned portion of the pin is wedged in the aforesaid opening between the holes and is screwed into one of the second holes of the shoulders of the second articulation.

Glasses frames including temples that may be worn comfortably beneath a head gear, such as helmets, headsets, earmuffs, hard hats, and speakers. In some cases, the temples may be thin, substantially flat, and flexible to allow the temples to deform without substantially increasing the pressure applied by the head gear to a head of a wearer.

Provided is eyewear comprising a front piece that has a metallic wraparound end piece and a non-metallic hinge member that constitutes a hinge portion together with the wraparound end piece. Thereby eyewear that is comfortable to wear and has a metallic front piece is provided.
