What is described is a hinge device for connecting the sides (2) to the fronts of spectacle frames (4), comprising a first and a second hinge element (6, 7) pivoting about a hinge axis (X), the first element (6) comprising a substantially fork-shaped body (8) with a first and a second arm (9, 10) opposed to one another, between which the second hinge element (7) is interposed, and a screw means (16) forming a hinge pin, passing through respective holes formed coaxially in the first and the second hinge element (6, 7), so as to be, respectively, locked by a screw engagement in the first hinge element (6) and housed rotatably in the second hinge element (7). The device further comprises at least a first anti-seizing sleeve (18) provided in the hole (13) of the second hinge element (7) and capable of being engaged by the hinge screw (16) in a rotatable coupling, the sleeve (18) comprising at least a first surface (20) extending in a contact area and capable of relative sliding between the hinge elements(6, 7), at least one ring (22) of elastically flexible material, fitted on the hinge screw (16) and capable of being deformed elastically as a result of the tightening of the screw so as to exert a relative pressure between the first and the second hinge element (6, 7), thereby increasing the friction provided between the hinge elements, and at least one bush (23) mounted in a seat of the first hinge element (6), coaxially with the hinge screw (16), and capable of accommodating the ring (22), the bush (23) including at one of its axial ends a bearing shoulder (24) for the ring (22), and being capable of making contact with the first surface of the anti-seizing sleeve (18), so that the bush (23) is biased axially against the sleeve (18) by the elastic action generated by the friction ring (22) as a result of the tightening of the hinge screw (16).

The present disclosure provides eyeglasses including: an eyeglass rim; an eyeglass temple, the eyeglass temple comprising a control circuit or a battery; a rotating shaft, the rotating shaft being configured to connect the eyeglass rim and the eyeglass temple, so that the eyeglass rim and the eyeglass temple are relatively rotated around the rotating shaft, and the rotating shaft being disposed with a rotating shaft wiring channel along an axial direction; and a speaker, the speaker comprising an earphone core, the speaker being connected to the eyeglass temple, the control circuit or battery in the eyeglass temple driving the earphone core to vibrate through the connection wire, wherein the earphone core vibrates to generate a driving force to drive a housing panel of the speaker to vibrate, and a straight line of the driving force being not parallel to a normal line of the housing panel.

The present invention relates to a novel screw that causes drag and prohibits unwinding of the screw. The screw is designed for use in eyeglasses for securing eyeglass lenses and prohibiting same from falling out. The screw includes a fillister head, a drive disposed on the head for engaging a screwdriver, a shaft running from the head to a terminal end, the shaft having non-contiguous circumferential threads along the length of the shaft for rotatably sliding the screw through slots. The screw includes a longitudinal channel in the form of a slot disposed along the surface of the shaft and through the length of the shaft. A planar bar of neoprene or any other polypropene can be inserted in the channel which assists with prohibiting unwinding of the screw when the screw is in use.
