摘要： A mouse device includes a casing and a roller module. The roller module is installed within the casing. The roller module includes a roller wheel, a movable magnet, a first magnet and a second magnet. In response to a repulsive force between the first magnet and the movable magnet, the roller module is in a tactile feel mode. In response to an attractive force between the second magnet and the movable magnet, the roller module is in a smooth scrolling mode.

摘要： A key structure includes a membrane switch circuit member, a rubbery elastomer, a housing, a triggering element, a metallic elastic element and a keycap. The keycap is disposed on the triggering element. The rubbery elastomer is disposed on the membrane switch circuit member. The housing is located over the rubbery elastomer. The triggering element is movable relative to the housing. The metallic elastic element is contacted with the triggering element. While the keycap is depressed, the triggering element is moved relative to the housing to press the metallic elastic element. While the metallic elastic element is pushed by the triggering element, the metallic elastic element is swung to collide with the triggering element. Consequently, a click sound is generated.

摘要： A keyboard with a vibration function is provided. The keyboard includes a base member, an upper cover, a basic key structure and a vibration key structure. The vibration key structure includes a control module, a vibration keycap and an isolation element. The control module is fixed on the upper cover. When the control module is triggered, a vibration key signal is generated and a vibration action is provided. The control module is covered by the vibration keycap. The vibration keycap is exposed outside the upper cover. The isolation element is arranged between the control module and the upper cover. The vibration key structure is enclosed by the isolation element, so that the energy of the vibration action from the control module is isolated.

摘要： A keyboard structure includes a keycap, a supporting plate, a connecting element and a clicking element. The keycap has a top surface and a bottom surface. The connecting element is connected with the keycap and the supporting plate. The clicking element is located under the keycap. While the keycap is descended, the clicking element is pressed by the push post and subjected to curvy deformation and then the clicking element is separated from the push post. When the clicking element is elastically restored to an original position to knock on the bottom surface of the keycap, a click sound is generated.

摘要： 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.

摘要： A keyboard device includes a key structure, a membrane wiring board and an elastic element. The elastic element is arranged between the key structure and the membrane wiring board. The key structure includes a sleeve, a plunger-type support shaft, a keycap and a resilience element. The plunger-type support shaft is movable upwardly or downwardly relative to the sleeve. When the keycap is depressed in response to an external force, the resilience element and the sleeve interfere with each other. Consequently, the keyboard device provides the operating sound and the operating feedback like a mechanical switch.

摘要： A key structure includes a support shaft, a resilience sheet, a pedestal and a keycap. While the keycap is pressed down in response to an external force, the support shaft is moved downwardly and the resilience sheet is correspondingly moved. Since a resilience part of the resilience sheet is pushed by a push part of the pedestal, the resilience part is subjected to deformation. After the resilience part is moved across the push part, the resilience part is elastically restored and swung. Consequently, the resilience part collides with the inner surface of the sliding groove to generate a click sound.
