when the key core 3 is pressed down, the tuning fork pressing block 8 presses the free end 701 of the tuning fork to downwards move along the inclined landslide 5 and downwards store force in a direction away from the key core 3, and when the free end 701 moves down to the bottom of the tuning fork pressing block 8, the free end 701 instantly upwards bounces to strike the inner wall of the key body positioned at the upper part of the free end 701 to make a striking sound; when the key core 3 is released and reset upwards, the tuning fork pressing block 8 moves upwards to leave the tuning fork free end 701, and the free end 701 instantly bounces towards the key core side to strike the inner wall of the key body positioned at the side to make a striking sound.
In order to improve the synchronicity between the sound production and the triggering, as shown in fig. 1-4, in the first embodiment, the triggering mechanism 4 is a movable member 402, a limiting slot 401 is disposed in the key body 14, the movable member 402 is embedded in the limiting slot 401, and the movable member 402 can move up and down along the inner side of the limiting slot 401;

9-11, in the second embodiment, the triggering mechanism 4 is an extending structure right below the key core 3, and the key core is pressed down, and the triggering mechanism below the key core moves downwards until the sensing module is triggered; after the key core is loosened, the key core is restored to the original position under the action of the reset spring, and the trigger mechanism moves upwards and is far away from the sensing module.
12-14, in the third embodiment, the triggering mechanism 4 is an extending structure (as shown in FIG. 14) on the side surface of the key core 3, the key core is pressed, and the triggering mechanism below the key core moves downwards until the sensing module is triggered; after the key core is loosened, the key core is restored to the original position under the action of the reset spring, and the trigger mechanism moves upwards and is far away from the sensing module. The triggering mechanism and the tuning fork are positioned on different sides in the key body and cannot affect each other.
The sensing module is a photoelectric switch or a Hall switch. Taking the first embodiment as an example, the lower end of the movable member 402 is provided with a photoelectric switch, the photoelectric switch is installed or the patch is arranged on the PCB board, a through hole 10 is further provided in the middle of the photoelectric switch, the lower end of the movable member is embedded in the through hole 10, and the movable member 402 can block the optical path of the photoelectric switch when being inserted into the through hole 10 at rest. When the movable piece moves upwards to leave the through hole, the photoelectric switch forms an optical path, so that the triggering operation can be finished, and the equipment obtains a triggering signal.
Taking the first embodiment as an example, the lower end portion of the movable member 402 is correspondingly provided with a hall switch, and the whole or the lower portion of the movable member 402 is made of a magnetic material. The movable member can be moved toward or away from the hall switch. When the movable piece moves upwards and is far away from the Hall switch, the magnetic flux changes, the triggering operation can be completed, and the equipment obtains a triggering signal at the moment.
In order to enable the lower end of the movable piece to be better embedded into the limiting hole, a through hole 10 with a trapezoid groove structure is correspondingly formed in the PCB 6, and the lower end of the movable piece 402 is of a trapezoid structure. The lower end that stretches out from the spacing groove when the moving part is static can be fine imbed in the through-hole on the PCB board, and trapezium structure's moving part, the lower extreme is narrow, and the upper end is wide. If the movable piece is of a rectangular structure, the movable piece can slide out of the limiting groove completely, and the installation is not facilitated.
In order to optimize the space structure, the limiting groove 401 is located at a corner of one side in the key body 14, and the movable part in the limiting groove is used only for hand feeling and sound, so that the up-and-down movement of the key core is not affected. The influence of the limiting groove on the up-and-down movement of the key core can be reduced by being positioned on the corners.
For easy installation, the key body 14 includes a key seat 1 and a key cover 13, and the key seat 1 and the key cover 13 are in snap connection. Or the key seat 1 and the key cover 13 are of an integrated structure, the key cover at the upper part is made of flexible materials, and the key core and other parts can be inserted and installed from the opening part of the key cover.
In order to allow the free end to move in the self-defined area, the tuning fork free end 701 is lower than the top of the tuning fork compact 8 when the key core 3 is pressed to the bottommost. A limiting block 15 is arranged at the top of the tuning fork pressing block 8. If the key core is pressed to the lowest part, the free end passes over the tuning fork pressing block, the free end is likely to collide once more, the free end is easy to clamp at the top of the tuning fork pressing block, the resistance is larger when the key is loosened for resetting, and the design hand feeling is poor. By adopting the tuning fork pressing block with enough length, the free end cannot pass over the top of the tuning fork pressing block when the key core is pressed to travel to the bottommost part, and the free end keeps a force storage state. Or through the stopper, the tuning fork free end is always lower than the top of tuning fork briquetting when the key core is pressed and goes to the bottommost.
In order to optimize the space structure, the key body 14 is respectively provided with an upper limiting wall 12 and a side limiting wall 11, the upper limiting wall 12 is located above the tuning fork free end 701 (the free end first emits the striking sound and strikes the upper limiting wall), and the side limiting wall 11 is located at one side of the tuning fork free end 701 (the free end second emits the striking sound and strikes the side limiting wall). The upper limiting wall is arranged on the key cover or the key seat, and the side limiting wall is arranged on the key cover or the key seat. The upper limit wall and the side limit wall can be arranged on the keycap or the keyseat according to the requirement. In fig. 6-7, the side limiting walls are provided on the key bed. When the key is used, as shown in fig. 2-4, the tension spring and the tuning fork in the key core can be pressed down only by a certain force, and good paragraph-type pressing hand feeling can be provided.
The tuning fork, the tuning fork pressing block and the inclined landslide are combined, so that the pressing hand feeling can be effectively improved, the striking sound with the paragraph feeling can be provided, the cost is low, and the installation is convenient; the combination of the movable part and the tuning fork is adopted, when the free end of the tuning fork is rebounded and reset, the free end of the tuning fork is impacted to make a sound, and at the same time, the free end also applies an upward acting force to the movable part to move upwards, so that the triggering is realized, and the synchronism of the two processes is good; meanwhile, the impact hammer is replaced by the movable piece, the movable piece is a part of a sound production structure and a triggering structure, and the movable piece is easier to manufacture and install than the impact hammer; the movable part is ingenious in structural combination, simple in structure, low in production and manufacturing cost, low in difficulty in combination among parts, high in installation efficiency and suitable for batch production and use; meanwhile, the tuning fork of the U-shaped metal elastic structure is high in fatigue resistance, not easy to wear and long in service life.
