The present disclosure embodiment may disclose glasses. The glasses may include a glasses frame and two speakers. The glasses frame may include a glasses rim and two glasses temples. The two glasses temples may be rotatably connected to the glasses rim, respectively. The two speakers may include an earphone core, respectively. The two speakers may be connected to the two glasses temples via hinge components of the two glasses temples, respectively. The hinge components may be rotatable to change a position of each of the speakers relative to connected one of the glasses temples to make the speaker abut in front of or behind ears of a user. The glasses temple may include a control circuit or a battery to drive the earphone core to vibrate to generate a sound. The glasses of the present disclosure may satisfy various requirements when a user wears the glasses, and the hinge state may be switched easily, thereby providing convenience for the user.

The present disclosure embodiment may disclose eyeglasses. The eyeglasses may include an eyeglass frame and two speakers. The eyeglass frame may include an eyeglass rim and two eyeglass temples. The two eyeglass temples may be rotatably connected to the eyeglass rim, respectively. The two speakers may include an earphone core. The two speakers may be connected to the two eyeglass temples via hinge components of the two eyeglass temples, respectively. Each hinge components may be rotatable to change a position of its connected speakers relative to one of the two eyeglass temples. The eyeglasses of the present disclosure may satisfy various requirements when a user wears the eyeglasses, and the hinge state may be switched easily, thereby providing convenience for the user.

Elastic hinge for plastic frames of eyeglasses, which comprises a first and a second articulation element respectively associable with a first and a second component of eyeglasses. The first articulation element comprises a male element which is susceptible of sliding inside a seat of the first component and comprises a head portion, a rod-like portion fixed to the head portion, an anchorage body slidably coupled to the rod-like portion and provided with a retention portion provided with anchorage elements. The first articulation element also comprises an expander body adapted to interfere with the anchorage body in order to externally expand the retention portion of the latter towards the internal wall of the seat so as to engage the anchorage elements of the retention body with the first component of the eyeglasses.

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.

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.

Systems and methods for a flexible, modular head-mounted display is provided. The head-mounted display system may comprise a base member and one or more arm members that are coupled to the base member. The arm member(s) may be coupled to the base member via a hinge system that allows the arm member(s) to move with respect to the base member. Interior walls of the hinge system may define a passage therethrough such that wiring may extend throughout the head-mounted display system. The head-mounted display system may further include a cover that encloses at least a portion of the hinge. The cover may overlap with the base member or the one or more arm members.

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.

Elastic hinge for eyeglass frames, which comprises an articulation screw engaged in the holes of two articulation elements. The articulation screw comprises a shank provided with a narrow portion, which is engaged in the hole of a first tab of an articulation element, and with an enlarged annular portion, which forms a step and is engaged in the hole of a head portion of the other articulation element. The articulation screw assumes an end stop position, in which it is tightened and aligned with the hinging axis, and a blocking position, in which it is loosened and is tilted with respect to the hinging axis in response to the elastic force exerted by an elastic device, such that the step of the articulation screw interferes with the edge of the hole of the first tab of the articulation element, preventing a further unscrewing of the articulation screw.

Provided is a rotating shaft mechanism of an electronic device. A first fixing assembly and a second fixing assembly in the rotating shaft mechanism are connected to each other by a first connector and a second connector. A hollow region can be reserved in the rotating shaft mechanism as the first connector and the second connector may be shorter. Thus, an external circuit of the electronic device can pass through the hollow region and be disposed in a second body of the electronic device. An electronic device is also provided.

Embodiments for systems, methods and apparatuses of eyewear are disclosed. One method includes treating a patient with shutter glasses therapy for a relatively short period of time, such as at least a 6 week period; wherein the shutter glasses therapy includes blanking a first lens of shutter glasses being worn by the patient for a first blocking time, blanking a second lens of the shutter glasses being worn by the patient for a second blocking time, and controllably setting at least one of the first blocking time and the second blocking time.
