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.

An artificial-reality device is provided. The artificial-reality device includes a frame having at least one temple section (e.g., a frame arm) and a front section, where the front section is configured to hold at least one lens. The artificial-reality device also includes a hinge pivotally coupling the at least one temple section and the front section. The hinge includes: (A) a front magnetic component that includes a static magnet, and (B) a rear magnetic component, coupled to the at least one temple section, that includes: (i) two or more primary magnets oriented so as to be attracted to the static magnet of the front magnetic component, and (ii) at least one secondary magnet, positioned between the two or more primary magnets, oriented so as to be repelled by the static magnet of the front magnetic component.

A photovoltaic (PV) panel mounting system for a vehicle includes: a PV panel movably mounted on a vehicle panel; a first electrode electrically connected to the PV panel; a second electrode attached to the vehicle panel and electrically connected to the first electrode; and a damping mechanism elastically supporting the PV panel with respect to the vehicle panel. The damping mechanism allows the PV panel to move between a first position and a second position. The first position refers to a position in which an outer surface of the PV panel is flush with an outer surface of the vehicle panel and the second position refers to a position in which the outer surface of the PV panel is recessed from the outer surface of the vehicle panel.

A connecting assembly for a wearable device, a wearable device, and a wearable apparatus are provided. The connecting assembly includes a first connector, a second connector, and a rotating mechanism. The first connector is configured to connect a housing assembly of the wearable device. The second connector is configured to connect a wearable assembly of the wearable device. The rotating mechanism is connected with the first connector and the second connector respectively. The first connector and the second connector are configured to rotate relative to each other through the rotating mechanism. The first connector is provided with a limiting portion at an end of the first connector away from the rotating mechanism, and the limiting portion is configured to cooperate with the housing assembly to limit movement of the first connector.

A temple assembly for a pair of spectacles, including a spectacle temple body, a guide member, a first temple core, a second temple core, a first pivot; and a second pivot; wherein the second temple core is elastically connected with the spectacle temple body, the guide member is sleeved onto the first temple core, two connecting end of the first temple core is respectively pivotally connected to the second temple core and a pile head of a rim, the first pivot and the second pivot are disposed perpendicular to each other. When the spectacle temples are subjected to loads in two different directions from a horizontal direction and a vertical direction, the spectacles temple cause to produce an elastic bend of different directions at a front end and a rear end of the guide member, the user experience that the temples can be rotated 360 degrees is better.

The invention relates to a central part for an eyeglass hinge, comprising: a first articulation region, which is designed to connect, with articulation about a first articulation axis, the central part to a frame of eyeglasses; a second articulation region, which is designed to connect, with articulation about a second articulation axis, the central part to a temple of the eyeglasses; and a cable guide opening, which extends through the central part perpendicularly to the articulation axes and is designed for the feeding of a cable from the temple to the frame through the central part, the cable guide opening being open in the direction of the articulation axes at least on one side.

A head-mounted wearable device (HMWD) with a form factor of eyeglasses incorporates hinges between a front frame and temples. The hinges provide a fully enclosed passage for a flexible printed circuit (FPC). The FPC allows electrical connectivity between devices in the front frame and in the temple. The hinge includes a cam device that provides a biasing force that allows the temples to remain in one of four configurations: closed, transit, neutral, and maximum neutral. When in the transit configuration the biasing force provided by the cam device tends to move the temples towards the closed configuration. When in the maximum neutral configuration the biasing force provided by the cam device tends to move the temples towards the neutral configuration. During use, this biasing of the temples provides a gentle clamping force that assists in maintaining the HMWD on the user's head.

A slip-resistant eyewear system comprising an angular adjustment screw configured to couple to a first hinge of an eyewear frame such that an angle of the eyewear frame is adjustable relative to a first bow and a unitary eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

The multiuse eyeglasses include a frame that holds two lenses and arms that extend from the frame. The arms include a first axis of rotation that is generally perpendicular to the arms and a second axis of rotation that is orthogonal to the first axis of rotation and allows the arms to be rotated downwards relative to the frame.
