Abstract: A keyswitch structure includes a casing, a first support, a second support, and a pressing stem. The casing forms an accommodating space and an opening communicating with the accommodating space. The first and second supports are disposed in the accommodating space and are directly and rotatably connected with the casing; the supports are also pivotally connected with each other. The pressing stem extends into the accommodating space to be rotatably connected with the first and second supports and protrudes from the casing through the opening. The pressing stem is movable parallel to a vertical direction relative to the casing through the first and second supports. A motion of the pressing stem in the vertical direction has a top dead center and a bottom dead center. When the pressing stem is at the top dead center and the bottom dead center, it does not touch the casing in the vertical direction.

Abstract: A keyswitch structure includes a keycap support mechanism and a keycap that is supported by the keycap support mechanism in a vertical direction. The keycap support mechanism includes a base and two supports. The base has two sliding slots. Each sliding slot has an opening in a horizontal direction and an obstruction block at the opening. The horizontal direction is perpendicular to the vertical direction. Each support has a sliding portion and a linkage portion. The sliding portions slide parallel to the horizontal direction in the sliding slots correspondingly. The obstruction block prevents the corresponding sliding portion from disengaging from the corresponding sliding slot. The two linkage portions push against each other in line contact, so that the two supports are mutually driven through the two linkage portions.

Abstract: A magnetic type keyswitch includes an actuating member and a switch unit. The actuating member is movable in response to a pressing force. The switch unit includes a circuit board, a Hall sensor electrically connected to the circuit board, and a magnet spaced apart from the Hall sensor by a fixed distance. When the pressing force is not applied, the magnet enables the Hall sensor to output a first voltage, and when the pressing force is applied, the actuating member moves relative to the magnet and the Hall sensor in response to the pressing force, so that the Hall sensor outputs a second voltage different from the first voltage, and the magnetic type keyswitch generates a triggering signal.

Abstract: A retractable headphone connection structure includes two connection supports which are slidably connected with each other in a sliding connection direction. One of the connection supports has a plurality of first magnetically attractive portions arranged at intervals along the sliding connection direction. The other of the connection supports has a second magnetically attractive portion. Therein, the two supports relatively slide to make the second magnetically attractive portion slide over the plurality of first magnetically attractive portions to generate a magnetic attraction force between the second magnetically attractive portion and one of the first magnetically attractive portions that is opposite to the second magnetically attractive portion. The magnetic attraction force positions the first connection support and the second connection support. A head-mounted audio device includes a headphone and the above retractable headphone connection structure.

Abstract: A key structure includes a base, a movable mechanism movably positioned on the base, a sound generating member positioned on the base, and an adjusting unit movable relative to the base to be at a first position or a second position. The sound generating member has a hitting portion, which extends corresponding to an impact surface. When the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound. When the adjusting unit is at the second position, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.

The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

Abstract: A keyswitch structure includes a lift mechanism and a keycap. Two supports of the lift mechanism support the keycap. There can be a spring structure connecting the two supports for driving the two supports to lift the keycap. The lift mechanism defines a central space extending through the whole lift mechanism in a vertical direction. The spring structure does not enter the central space. The two supports abut against and constrain each other through corresponding structures, to mutually rotate with respect to a rotation axis. The keyswitch structure can include a switch. The switch includes an intermediate support, detachably abutting downward against the lift mechanism or the keycap, and a resilient part, detachably abutting downward against the intermediate support. In the process of pressing the keycap, the intermediate support is separated from the lift mechanism or the keycap, so that the contact force of the switch can be maintained constant.
