Description

Technical Field

[0001] This utility model is a key-sound-effect keyboard, belonging to the field of computer keyboard technology. Background Technology

[0002] Currently, computers have become indispensable for office work and entertainment, and the keyboard is an external input device that computers cannot replace. The sound produced when typing is considered noise, which can affect the mood of oneself and others, reducing work efficiency and entertainment enjoyment.

[0003] To address these issues, keyboards have evolved in two directions: silent keyboards, suitable for office use, and music-enhancing keyboards, suitable for personal use.

[0004] Among them, silent keyboards are technically difficult, have high production costs, and are developing slowly. Music keyboards, on the other hand, do not require changes to the traditional mechanical structure, and therefore have become the current development direction. This application provides a key sound effect keyboard that can produce different sound effects when the user presses the keys, thereby improving the keyboard's entertainment effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a key sound effect keyboard.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A key-sound keyboard includes a housing, inside which is a key unit, the key unit including keys and a circuit board, and a protective shell on the outside of the circuit board. Several keys are located above the protective shell, each key including a keycap and a switch, the keycap being mounted on the top of the switch, the bottom of the switch penetrating into the protective shell and connecting to contacts on the circuit board, and a sound effect mechanism cooperating with the keycap is provided on the protective shell and located on the side of the switch.

[0008] Furthermore, the sound effect mechanism includes a card slot and a sound chip, the sound chip being fixed to the side of the card slot, and a limiting slot being formed at the bottom of the card slot on the side away from the sound chip.

[0009] Furthermore, the sound effect mechanism also includes a slot formed on the top of the protective shell, the slot being adapted to the locking seat, a groove being formed on one side of the inner wall of the slot to cooperate with the limiting slot, an elastic element being provided on one side of the groove, a locking plate being laterally slidably connected in the groove to cooperate with the limiting slot, the locking end of the locking plate being locked in the limiting slot, and the straight end of the locking plate being pressed together with the elastic element.

[0010] Furthermore, screw holes are provided at the bottom of the groove, the top of the protective shell, and the snap-fit ​​plate, and the three sets of screw holes are connected and fixed by connecting screws.

[0011] Furthermore, a toggle element is provided between the protective shell and the snap-fit ​​plate. The toggle element includes movable holes symmetrically opened on both sides of the connecting screw. A movable plate is rotatably connected in the movable holes. A set of toggle grooves that cooperate with the toggle block are respectively opened on the top two sides of the snap-fit ​​plate.

[0012] Furthermore, a set of rotating shafts are symmetrically fixed on both sides of the movable plate, and a rotating hole that cooperates with the rotating shaft is opened in the movable hole.

[0013] Furthermore, both sides of the top of the movable plate are provided with actuating blocks, and the inner wall of the movable hole is provided with a damping pad layer that cooperates with the side of the movable plate.

[0014] Furthermore, the housing includes a bottom shell and a cover plate, the cover plate being fixed to the top of the bottom shell, the bottom shell and the cover plate forming an accommodating space, the button and the circuit board being located within the accommodating space, and the cover plate having a button groove that mates with the button.

[0015] The beneficial effects of this utility model are:

[0016] Through the design of the sound effect mechanism, when the user presses the key, the keycap on the key will press the sound plate below as it falls. The impact will produce a musical sound, thus creating the sound effect of the keyboard being pressed. By setting sound plates of different lengths under several keys, different sound effects can be created.

[0017] Due to the design of the toggle mechanism, the soundboard may wear out or be damaged during long-term use of the keyboard. In order to replace a single damaged soundboard, the toggle block is pulled to rotate the movable plate. As the movable plate rotates, one end will gradually screw into the groove, and then into the toggle slot on the top of the snap-fit ​​plate. This will cause the snap-fit ​​plate to move laterally, so that the snap-fit ​​plate disengages from the limiting slot on the snap-fit ​​base. This allows the snap-fit ​​base to be pulled out of the slot, and then the snap-fit ​​base and the soundboard can be replaced.

[0018] The design of the toggle block makes it easy for users to pull the movable plate inside the movable hole to rotate, thereby achieving the purpose of quickly activating the toggle component.

[0019] The design of the damping pad provides damping constraint between the inner wall of the movable hole and the outer wall of the movable plate, thereby enabling the movable plate located in the movable hole to maintain a stable horizontal state. Attached Figure Description

[0030] Please see Figures 1-7This utility model provides a key-sound keyboard technology solution, including a housing. Inside the housing is a key unit 3, which includes keys and a circuit board. A protective shell 17 is provided on the outside of the circuit board. Several keys are located above the protective shell 17. Each key includes a keycap and a switch. The keycap is mounted on the top of the switch, and the bottom of the switch extends through the protective shell 17 and connects to contacts on the circuit board. A sound effect mechanism that cooperates with the keycap is provided on the protective shell 17 and located on the side of the switch. The housing includes a bottom shell 1 and a cover plate 2. The cover plate 2 is fixed to the top of the bottom shell 1. The bottom shell 1 and the cover plate 2 together form a receiving space. The keys and the circuit board are located within this receiving space, which provides safety protection for the keys and the circuit board. A key groove that cooperates with the keys is provided on the cover plate 2.

[0031] See Figures 4-7 The sound effect mechanism includes a locking base 10 and a sound chip 11. The sound chip 11 is fixed to the side of the locking base 10. A limiting slot 12 is formed on the bottom of the locking base 10 away from the sound chip 11. The sound effect mechanism also includes a slot 4 formed on the top of the protective shell 17. The slot 4 is adapted to the locking base 10. A groove 5 is formed on one side of the inner wall of the slot 4 to cooperate with the limiting slot 12. An elastic element 6 is provided in the groove 5 on one side. A locking plate 7 that cooperates with the limiting slot 12 is slidably connected in the groove 5. The locking end of the locking plate 7 is locked. Within the limiting slot 12, the flat end of the snap-fit ​​plate 7 is pressed together with the elastic member 6. Screw holes 8 are provided on the bottom of the groove 5, the top of the protective shell 17, and the snap-fit ​​plate 7. The three sets of screw holes 8 are connected and fixed by connecting screws 18. Through the design of the sound effect mechanism, when the keyboard is in use, the user's fingers press the keys. As the keycaps on the keys descend, the bottom of the keycaps will press the sound plate 11 below. The impact will produce a musical sound, thus forming the sound effect of keyboard typing. By setting sound plates 11 of different lengths under several keys, different sound effects can be formed.

[0032] See Figure 7A toggle element is provided between the protective shell 17 and the snap-fit ​​plate 7. The toggle element includes movable holes 13 symmetrically opened on both sides of the connecting screw 18. A movable plate 14 is rotatably connected in the movable holes 13. A set of toggle grooves 9 that cooperate with the toggle blocks 16 are respectively opened on the top two sides of the snap-fit ​​plate 7. A set of rotating shafts 15 are symmetrically fixed on both sides of the movable plate 14. A rotating hole that cooperates with the rotating shaft 15 is opened in the movable hole 13. A toggle block 16 is provided on both sides of the top of the movable plate 14. The inner wall of the movable hole 13 is provided with a toggle block 16 that cooperates with the movable plate. 14. Damping pads that cooperate with the side; Through the design of the toggle, the sound chip 11 may wear or be damaged during long-term use of the keyboard. In order to replace a single damaged sound chip 11, the toggle block 16 is pulled to rotate the movable plate 14. As the movable plate 14 rotates, one end will gradually screw into the groove 5, and then gradually screw into the toggle groove 9 on the top of the snap-fit ​​plate 7, causing the snap-fit ​​plate 7 to move laterally, so that the snap-fit ​​plate 7 is disengaged from the limiting slot 12 on the snap-fit ​​base 10, so that the snap-fit ​​base 10 can be pulled out from the slot 4, and then the snap-fit ​​base 10 and the sound chip 11 can be replaced.

[0033] When the keyboard is in use, the user's fingers strike the keys. As the keycaps on the keys descend, their bottoms press against the sound plates 11 below. The impact produces a musical sound, thus creating the sound effect of the keyboard being struck. By setting sound plates 11 of different lengths under several keys, different sound effects can be created. During long-term use, the sound plates 11 may wear out or become damaged. To replace a single damaged sound plate 11, the toggle block 16 is pulled to rotate the movable plate 14. As the movable plate 14 rotates, one end gradually screws into the groove 5, and then into the toggle slot 9 on the top of the latching plate 7. This causes the latching plate 7 to move laterally, disengaging it from the limiting slot 12 on the latching base 10. This allows the latching base 10 to be pulled out from the slot 4, and the latching base 10 and the sound plate 11 can then be replaced.
