Description

A keyboard capable of switching key tapping sounds Technical Field

[0001] The invention relates to a keyboard device, in particular to a keyboard capable of switching key tapping sounds. Background Art

[0002] The current input device is a device that inputs data and information into the computer. It is a bridge for the computer to communicate with the user or other devices, such as a keyboard. The keyboard is composed of a number of key switches.

[0003] The text of Chinese utility model patent No. 202223562053.1 discloses "an ultra-thin balanced key with stable assembly", and in specific embodiment three, it discloses a sounding key. By adding a sounding mechanism, the key has a sounding function that can make a knocking sound when pressed. The sounding mechanism is installed on the linkage wing, and the sounding block for limiting the sounding torsion spring is fixedly installed on the switch fixing plate. Once this keyboard is given a sounding function, it does not have a mute function. However, many users hope that the keyboard has both silent and sounding modes, and can be switched instantly according to the use environment. Based on this, the purpose of the present invention is to provide a scheme for a keyboard with switchable key knocking sound. This scheme can at least be implemented in the aforementioned ultra-thin balanced key, and of course it is not limited to the ultra-thin balanced key. Summary of the Invention

[0004] In view of the above problems, the present invention aims to provide a keyboard with switchable key tapping sounds that is ingenious in structure and easy to use.

[0005] To achieve this technical objective, the present invention provides a keyboard capable of switching key click sounds, the keyboard comprising a switch fixing plate and a plurality of key switches disposed on the switch fixing plate, the key switches having sound-generating structures for emitting click sounds when pressed, a switch plate movable relative to the switch fixing plate disposed at the bottom of the switch fixing plate, the switch plate being provided with a plurality of structural members extending into the key switches, the structural members corresponding one-to-one to the key switches;

[0006] The switch fixing plate is provided with a through hole for allowing the structural member to enter the corresponding key switch and allowing the structural member to move with the switching plate; moving the switching plate can change the position of the structural member in the corresponding key switch and thereby change the interaction state between the structural member and the sound-generating structure, so as to determine whether the sound-generating structure makes a sound or is silent when the key switch is pressed.

[0007] Preferably, the sound-producing structure includes a sound-producing torsion spring fixed on the key switch for storing force for sound production, the sound-producing torsion spring having a fixed arm and a sound-producing arm that maintains downward tension; the sound-producing structure also includes a sound-producing part constructed on the key switch, the sound-producing part having a knocking end platform and an inclined platform located above the knocking end platform, and the sound-producing arm abuts against the knocking end platform in a natural state; the structural member on the switching plate is a convex column, and the convex column is constructed to be adjacent to the sound-producing arm of the corresponding key switch, and the convex column affects whether the sound-producing arm can store force and produce sound normally as the switching plate moves.

[0008] Preferably, the switch fixing plate is provided with a sound-generating force-storing boss corresponding to the bottom of the sounding arm, and when the push switch is pressed down, the arm of the sounding arm can be stopped by the boss to store force until the inclined platform pushes the sounding arm away from the boss and quickly hits the knocking end platform to produce a knocking sound; the through hole for the boss to pass through is a limiting inclined slot hole, and the height of the boss is higher than the sounding arm; when the boss is located at one end of the limiting inclined slot hole, it does not interact with the sounding arm, and when the boss is moved to the other end of the limiting inclined slot hole, the side of the boss abuts against the side of the sounding arm to bend the sounding arm away from the sound-generating force-storing boss, so that the sounding arm does not contact the sound-generating force-storing boss and cannot store force to produce sound.

[0009] Preferably, the through hole for the boss to pass through is a limiting bevel slot hole. When the boss is located at one end of the limiting bevel slot hole, the top of the boss is located at the bottom of the sounding arm. When the push switch is pressed down, the sounding arm can be stopped by the top of the boss to store force until the inclined platform pushes the sounding arm away from the top of the boss and quickly hits the knocking end platform to produce a knocking sound; when the boss is moved to the other end of the limiting bevel slot hole, it is away from the bottom of the sounding arm, so that the sounding arm does not contact the top of the boss and cannot store force to produce sound.

[0010] Preferably, the switch fixing plate is provided with guide columns at both ends, and the switching plate is provided with guide grooves at both ends for enabling the guide columns to move therein, and the directions of the guide grooves are consistent with those of the limiting inclined slot holes.

[0011] Preferably, an assembly frame is installed at the bottom of the switch fixing plate, and the switching plate is movably arranged between the switch fixing plate and the assembly frame.

[0012] Preferably, the push button switch includes two linkage parts pivotally connected to each other, a reset spring and a keycap buckled on the two linkage parts, the reset spring is connected between the two linkage parts, and the sound-emitting structure is constructed on one of the linkage parts; a structure for assembling the two linkage parts is constructed on the switch fixing plate.

[0013] The beneficial effects of the present invention are as follows: the keyboard of the present invention cleverly sets a movable switching plate at the bottom of the keyboard, and changes the position of the structural parts on the switching plate that extend into the key switch to determine whether the sound-generating structure in the key switch can emit a knocking sound; this solution enables the keyboard to have both sound and silent modes, and can conveniently switch between the two modes by moving the switching plate. It has a sophisticated design, high stability, and is easy to manufacture. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the clear description of the embodiments. They do not indicate or imply that the devices or components referred to must have a specific orientation and should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" in the embodiments are used solely for descriptive purposes and do not indicate or imply relative importance.

[0031] As shown in Figures 1-14, a specific embodiment of the present invention is a keyboard with switchable key knocking sound. The keyboard includes a switch fixing plate 1 and a plurality of key switches 2 arranged on the switch fixing plate 1. The key switch 2 has a sound-emitting structure 3 for making a knocking sound when pressed. The bottom of the switch fixing plate 1 is also provided with a switching plate 4 that can move relative to the switch fixing plate 1. The switching plate 4 is provided with a plurality of structural members extending into the key switches 2. The structural members correspond one-to-one to the key switches 2. For the sake of ease of understanding, this application only shows one key switch 2 in the figure. In fact, each structural member corresponds one-to-one to a key switch 2.

[0032] The switch fixing plate 1 is provided with a through hole 101 for allowing the structural member to enter the corresponding key switch 2 and allowing the structural member to move with the switching plate 4; moving the switching plate 4 can change the position of the structural member in the corresponding key switch 2 and thereby change the interaction state between the structural member and the sound-generating structure 3, thereby determining whether the sound-generating structure 3 will make a sound or be silent when the key switch 2 is pressed.

[0033] The key switch 2 in this solution can be a key switch 2 of various forms. A sound-generating structure 3 is installed in the key switch 2. By changing the position of the structural member on the switching plate 4 extending into the key switch 2, it is determined whether the sound-generating structure 3 in the key switch 2 can emit a knocking sound.

[0034] The key switch 2 of the specific embodiment of this solution includes two pivotally connected linkages 201, a return spring, and a keycap 202 that snaps onto the two linkages 201. The return spring is connected between the two linkages 201, and a sound-generating structure 3 is configured on one of the linkages 201. The switch fixing plate 1 is configured with a structure for assembling the two linkages 201. For details on the specific structure of the key, please refer to the key used in patent No. "202223562053.1," entitled "A Stably Assembled Ultra-Thin Balanced Key." Details will not be repeated here, but it should be noted that this solution can be implemented in at least the aforementioned ultra-thin balanced key, but is not limited to such ultra-thin balanced key.

[0035] The sound-producing structure 3 in this specific embodiment includes a sound-producing torsion spring 301 fixed on the key switch 2 for storing force for sound production, and the sound-producing torsion spring 301 has a fixed arm 3011 and a sound-producing arm 3012 that maintains downward tension; the sound-producing structure 3 also includes a sound-producing part 302 constructed on the key switch 2, and the sound-producing part 302 has a knocking end platform 3021 and an inclined platform 3022 located above the knocking end platform 3021, and the sound-producing arm 3012 abuts against the knocking end platform 3021 in a natural state; the structural member on the switching plate 4 is a boss 6, and the boss 6 is constructed to be adjacent to the sound-producing arm 3012 of the corresponding key switch 2, and the boss 6 affects whether the sound-producing arm 3012 can store force and produce sound normally as the switching plate 4 moves.

[0036] This application provides the following two specific embodiments for switching key tapping sounds:

[0037] As a specific embodiment 1 of this application:

[0038] As shown in Figures 9-10, the switch fixing plate 1 is provided with a sound-generating force-storing boss 5 corresponding to the bottom of the sounding arm 3012. When the push switch 2 is pressed down, the arm of the sounding arm 3012 can be stopped by the boss to store force until the inclined platform 3022 pushes the sounding arm 3012 away from the boss and quickly hits the knocking end platform 3021 to make a knocking sound; the through hole 101 for the boss 6 to pass through is a limiting inclined slot hole, and the height of the boss 6 is higher than the sounding arm 3012; when the boss 6 is located at one end of the limiting inclined slot hole, it does not interact with the sounding arm 3012. When the boss 6 is moved to the other end of the limiting inclined slot hole, the side of the boss 6 abuts against the side of the sounding arm 3012, causing the sounding arm 3012 to bend away from the sound-generating force-storing boss 5, so that the sounding arm 3012 does not contact the sound-generating force-storing boss 5 and cannot store force to make a sound.

[0039] As a specific embodiment 2 of this application:

[0040] As shown in Figures 11-12, the through hole 101 opened on the switch fixing plate 1 for the boss 6 to pass through is a limiting bevel slot hole. When the boss 6 is located at one end of the limiting bevel slot hole, the top of the boss 6 is located at the bottom of the sounding arm 3012. When the push switch 2 is pressed down, the sounding arm 3012 can be stopped by the top of the boss 6 to store force until the inclined platform 3022 pushes the sounding arm 3012 away from the top of the boss 6 and quickly hits the knocking end platform 3021 to make a knocking sound; when the boss 6 is moved to the other end of the limiting bevel slot hole, it is away from the bottom of the sounding arm 3012, so that the sounding arm 3012 does not contact the top of the boss 6 and cannot store force to make a sound.

[0041] The switch fixing plate 1 is provided with guide posts 102 at both ends, and the switching plate 4 is provided with guide slots 401 at both ends for the guide posts 102 to move within. The guide slots 401 are aligned with the direction of the limiting bevel slots, ensuring that the entire protrusion 6 remains in the same direction when the switching plate 4 is dragged. To facilitate switching, the switching plate 4 can also be provided with a pull ring at one end to facilitate dragging.

[0042] In order to assemble the switching plate 4 and enable it to slide at the bottom of the switch fixing plate 1, an assembly frame 7 is installed at the bottom of the switch fixing plate 1. The switching plate 4 is movably arranged between the switch fixing plate 1 and the assembly frame 7. Specifically, the assembly frame 7 is provided with an assembly hole 701, and the switch fixing plate 1 is provided with a fixing column 103 matching the assembly hole 701.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the technical solution of the present invention.
