Abstract: A mouse device includes a roller module. The roller module includes a base member, a scroll wheel, a magnetic conductor, a swingable arm, a driving motor and an actuating element. The scroll wheel is installed on the base member. The magnetic conductor is located beside the scroll wheel. When the scroll wheel is rotated, the magnetic conductor is correspondingly rotated. The swingable arm is installed on the base member. The swingable arm includes a magnetic element. The swingable arm is swingable relative to the magnetic conductor. When the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor. Consequently, a magnetic attraction force between the magnetic element and the magnetic conductor is generated. When the swingable arm is swung to a second position, the magnetic attraction force between the magnetic element and the magnetic conductor is eliminated.

Abstract: A key structure includes a keycap, a pedestal and an elastic element. The keycap includes a main body and a coupling shaft. The pedestal includes a key slot. The key slot has an upper part and a lower part. The coupling shaft is penetrated through the upper part of the key slot and movable within the key slot upwardly or downwardly. The elastic element is installed in the lower part of the key slot. After an external force applied to the keycap is released, the elastic element is elastically restored, so that the keycap is returned to an original position. At the same time, the buffering elements in the key slot interfere with the coupling shaft. Consequently, an ascending speed of the keycap is reduced, and a click sound generated from the collision between keycap and the pedestal is reduced.

Abstract: A knob structure for adjusting a sound parameter is provided, which includes a knob, an encoder, an interference component and a switching module. The knob has a shaft portion and an internal teeth portion. The encoder is connected to the shaft portion of the knob, in which the encoder includes a turntable and a bottom plate. The turntable has one or more protrusions in contact with the bottom plate. When the knob is rotated to rotate the turntable of the encoder, the one or more protrusions rub against the bottom plate. The interference component has a first end adjacent to the internal teeth portion of the knob. The switching module is configured to make the first end of the interference component be in contact with or moved away from the internal teeth portion of the knob. A headphone including the knob structure is also provided.

Abstract: A roller module includes a scroll wheel, a magnetization member, a swinging element and a pole-reversible magnetic element. The magnetization member is synchronously rotated with the scroll wheel. The swinging element includes a pivotal part, a first magnetic element and a second magnetic element. The first magnetic element and the second magnetic element are movable by using the pivotal part as a rotation center. The pole-reversible magnetic element and the first magnetic element interact with each other. Consequently, the second magnetic element is close to or away from the magnetization member.

Abstract: A key structure includes a casing, a covering member, a pressing element, a triggering post, a switch element. The casing has an opening. The opening is covered by the covering member. The pressing element is disposed within the opening and connected with the covering member. The pressing element includes a middle part and an extension part. The triggering post is installed on the middle part of the pressing element. The triggering post is extended in the direction toward the inner position of the casing. When an external force is applied to the middle part of the pressing element, the triggering post is moved toward the switch element to push the switch element. When the external force is applied to the extension part of the pressing element, the triggering post is correspondingly moved with the pressing element in an inclined manner to push the switch element.
