A head-mounted display apparatus includes a display unit, a support portion configured to support the display unit, and a cover member is removably provided to the support portion. The cover member includes a contact portion that is positioned on a facing surface facing the support portion and that comes into contact with the support portion, and a first protruding portion that is positioned on the facing surface and that protrudes toward the support portion to be inserted into the support portion. At least one of the cover member and the support portion includes a magnet that attracts the other one by a magnetic force. The contact portion and the first protruding portion are provided on an inner side with respect to an outer edge of the cover member when the cover member is viewed in the direction opposite to the first direction.

An apparatus includes a container, a plurality of lights and a circuit. The container may comprise an outer shell comprising a material configured to protect contents of the apparatus and an inner surface. The outer shell may be configured to open to enable the contents to be placed on the inner surface. A cavity may be formed within the container when the outer shell is closed. The plurality of lights implemented on the inner surface may each be configured to adjust a characteristic of light output in response to a signal. The circuit may be configured to generate the signal in response to an input. The circuit may be implemented between the outer shell and the inner surface. A reactive material of the contents of the container may be configured to change appearance in response to the characteristic of light.

Systems, devices, and methods for wearable heads-up displays (WHUD) are described. A WHUD includes a front frame with two openings each with one recess which extends along at least a portion of the periphery of the openings, two arms including frame portions and temple portions, two lenses, a projector to generate light, and a holographic optical element (HOE) carried by a lens to redirect light to an eye of a user. Frame portions insert into the recesses and are held in place when the lenses are inserted into the recesses, wherein when the WHUD is assembled the projector and HOE are positioned correctly to create a display for the user. The assembled WHUD is inflexible where the front frame and arms are attached such that when worn the projector maintains a fixed position relative to the HOE and the display remains undistorted and visible to the user.

An optic focusing cover. The optic focusing cover includes a cylindrical body with openings at both ends. A corrective lens is disposed within the cylindrical body such that it covers the entire opening. The corrective lens is capable of further magnifying the telescope. A cap is attached to a first side of the cylindrical body, the cap is capable of going from an open to a closed configuration. A second end of the cylindrical body is configured to be accepted by a telescope.

An optical element includes an optical lens produced by an additive manufacturing method and a holder formed at least in part with the optical lens by the additive manufacturing method. The holder is adapted for cooperation with a manufacturing machine to thereby position the optical lens at a predetermined position in the manufacturing machine. A corresponding assembly and a method of manufacturing an optical element are also described.

The present disclosure provides a pivotable eyeglass frame. In one aspect, the pivotable eyeglass frame includes a rim capable of receiving two lenses therein, and two temple bars, each being rotatably coupled to the rim via a hinge and having an anchoring pad mechanically coupled to the temple bar via a stepper column such that the rim is pivotable about the stepper column in steps.

Eyewear for outputting audio information to the wearer include an eyewear temple, which has at least one loudspeaker. The eyewear temple is configured for placement on an ear of the wearer and spaced apart from an ear opening of the wearer's ear so that the sound waves generated by the loudspeaker are transmitted over the surroundings to the spaced ear opening. The loudspeaker is an ultrasonic loudspeaker. The eyewear has a parametric audio unit that includes the ultrasonic loudspeaker and configured to generate an audible sound beam directed at the ear.

A transformative, collapsible, portable and versatile personal display system is disclosed having a compact, lightweight collapsible structure enabling applications from eyeglass form virtual, augmented, mixed or experimental reality to a comfortable, portable wristwatch form. The system may be employed at public events and manifestations and permit the unique simultaneous transmission to a multiplicity of locations.

The present disclosure relates to a loudspeaker. The loudspeaker may include a loudspeaker mechanism, a fixing mechanism, and a connector. The loudspeaker mechanism may be configured to generate a vibration signal and transmit the vibration signal to the human body. The fixing mechanism may be configured to support and maintain the position of the loudspeaker mechanism. The connector may be configured to connect the loudspeaker mechanism with the fixing mechanism. The loudspeaker mechanism may at least include a first fixed position and a second fixed position. The first fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a non-working state. The second fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a working state. The connector may be configured to switch the loudspeaker mechanism between the first fixed position and the second fixed position.

Techniques for providing wearable electronic devices with electrical components are disclosed. The electrical components can provide electrical technology to eyewear to facilitate audio support including enhanced hearing. The electrical components can operate independently or together with other electrical components provided elsewhere. The wearable electronic devices with electronic components can, for example, provide audio output, audio enhancements, or event-related audio content.
