A push-button switch has a sound function and a button accepts a pushing operation. A second plunger slides in coordination with the pushing operation on the button. A torsion coil spring stores or releases elastic energy together with sliding of the second plunger. A sounder unit slides using elastic energy released by the torsion coil spring at the same time as the torsion coil spring elastically deforms, and the sounder unit generates a hitting sound by impacting a hitting piece. A movable contact piece has a movable-side contact Pm and is capable of moving due to being pushed by the sliding sounder unit. A fixed contact piece has a fixed side contact, the movable-side contact Pm being engaged with the fixed side contact at the same time or substantially at the same time as the sounder unit hits the hitting piece.

A keyswitch structure includes a base having a positioning means, an cover combined with the base, a plunger with an cam portion movably coupling with the cover relative to the base, a restoring unit disposed between the base and the plunger to provide a restoring force to enable the plunger to move along a direction away from the base, a tactile feedback member having a positioning portion positioned by the positioning means and an extending arm extending across a moving path of the cam portion, and an adjusting unit being movable to drive the positioning portion to shift, so that the tactile feedback member has a first deformation or a second deformation, and a pressing force required for the cam portion to pass the extending arm when the plunger moves toward the base is changed.

A method may include accessing audio data, obtaining tactile audio data associated with the audio data, and, while reproducing the audio data, reproducing a tactile audio response according to the tactile audio data in a manner personalized to a user. The tactile audio data may be reproduced via an electroactive transducer to transfer the tactile audio response to a body of a user. Another method may include obtaining audio data, parsing the audio data to identify an audio component that includes an audio layer or an audio source, and identifying an audio attribute of the audio component. The method may also include selecting the audio component to accompany a tactile audio response, generating tactile audio data that describes the tactile audio response for the selected audio component, and coordinating the tactile audio data of the selected audio component with the audio data of the selected audio component.

A key module (110) for a keyboard is presented. The key module (110) comprises a key tappet (220). The key tappet (220) comprises a coupling portion (322) for coupling with a keycap for the key module (110). The key tappet (220) comprises at least one guiding portion (326, 328) for guiding a translational actuation movement of the key tappet (220) between a rest position and an actuated position. The key tappet (220) comprises at least one tappet stop (324) for limiting the actuation movement. The key module (110) also comprises a trigger element (350) for triggering a switch signal of the key module (110) in response to the actuation movement. The trigger element (350) is attachable to the key tappet (220). The key module (110) further comprises a module housing (230), wherein the module housing (230) is integrally formed. The module housing (230) comprises at least one positioning protrusion (334) for positioning the key module (110) and a circuit substrate of the keyboard. The module housing (230) is formed to movably accommodate the key tappet (220), in order to enable the actuation movement of the key tappet (220) relative to the module housing (230). The module housing (230) comprises at least one housing stop (332) for abutment against the at least one tappet stop (324) of the key tappet (220) in the rest position of the key tappet (220). Moreover, the key module (110) comprises elastic means (340). The elastic means (340) is configured to bias the key tappet (220) into the rest position in an assembled state of the key module (110).

A key structure includes a base plate, a key cap, a positioning base, a positioning cover, and a spring. The key cap is disposed above the base plate and has a bottom surface. The positioning base is connected to the bottom surface of the key cap and has a positioning recess. The positioning cover is slidably connected to the positioning base, is inserted into the positioning recess, and includes a bottom portion and a side wall. The spring includes a first spring portion and a second spring portion. The first spring portion is located in the positioning recess and is in contact with the bottom surface of the key cap. The second spring portion is located in the positioning cover.
