Description

Technical Field

[0001] The utility model relates to the technical field of beautiful sound pads, in particular to a beautiful sound pad used for a mechanical keyboard with an axis lamp. Background Art

[0002] As an indispensable input device in modern life, keyboards have a wide range of usage scenarios. In order to improve the feel and sound performance, many technical upgrades have been made. However, the current traditional mechanical keyboards (with shaft lights) have a disadvantage. In order to let the light out, mechanical keyboards with shaft lights have light holes opened on their fillers and PCB boards. This causes the key press sound of the keyboard to radiate through the light holes, making the key press sound become hollow and very unpleasant.

[0003] In order to improve the sound performance caused by the sound leakage of the lamp hole, please refer to the Figure 2 The existing solution is to add a PET plastic sheet 2 (beautiful sound pad) between the top of the keyboard PCB board 3 and the IXPE shaft pad 1, which can greatly solve the degradation caused by the sound penetrating and radiating from the lamp hole. However, since the PET plastic film 2 is in direct contact with the PCB board and completely isolates the IXPE shaft pad from the PCB, it has a significant negative impact on the sound performance, which is mainly manifested in a slight plastic friction sound when the keys are struck. This has a greater impact on all-metal keyboards and cannot truly reflect the optimization effect of metal on echo. Utility Model Content

[0004] The purpose of the utility model is to provide a keyboard beauty pad and a keyboard, and to solve the problem of keyboard sound degradation caused by lamp holes at the source.

[0005] To achieve the above object, a keyboard music pad is provided, which includes a music pad body, wherein the music pad body is arranged above the pad under the keyboard axis;

[0006] The body of the beautiful sound pad is provided with an avoidance hole, and a protrusion extends from the avoidance hole toward the lamp hole of the pad under the shaft, and the protrusion is used to block the lamp hole;

[0007] The protrusion is a light-transmissive layered structure.

[0008] The above-mentioned beautiful sound pad (i.e., the PET plastic sheet in the prior art) improves the hole opening scheme of the PET plastic sheet, and also changes the installation position of the PET plastic sheet, which is specifically placed between the keyboard PCB board and the pad under the shaft and the sandwich cotton. The special hole shape avoids the degradation of the key echo caused by the direct contact between the bottom of the mechanical shaft and the PET plastic sheet. After the bottom of the mechanical shaft is installed in place, it can also avoid the friction noise caused by the direct contact between the PET plastic sheet and the PCB board in the existing design, thereby blocking the lamp hole without affecting the light transmittance of the shaft lamp. This invention also improves the negative impact brought by the direct contact between the PET plastic sheet and the PCB board, and perfectly solves the problem of echo degradation of the mechanical keyboard.

[0009] As a further improvement of the technical solution, the overall contour of the avoidance hole is adapted to the outer contour of the bottom of the keyboard mechanical axis to avoid the position where the bottom of the mechanical axis contacts the pad under the axis.

[0010] As a further improvement of the technical solution, the avoidance hole is in a "concave" shape when viewed from above, so that the protrusion is directly formed on the main body of the sound pad.

[0011] A keyboard is also provided, comprising a base, an upper cover is arranged on the top of the base, a notch is provided on the top of the upper cover to expose the mechanical axis, after the base and the upper cover are connected, an accommodation space is formed between the two, a PCB board is arranged in the accommodation space, an axis pad is arranged above the PCB board, and the above-mentioned beautiful sound pad body is arranged above the axis pad;

[0012] The mechanical axis falls into its corresponding avoidance hole.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The keyboard uses an "concave"-shaped avoidance hole in the keyboard's sound pad. The special shape of the hole forms a protrusion that only closes the lamp hole on the PCB board, and can avoid the contact position between the bottom of the mechanical axis and the pad under the axis. This ensures the perfect order of mechanical axis-pad under the axis-PCB board while sealing the lamp hole to avoid echo divergence. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] With the development of mechanical keyboards, there is a consensus on the axis echo. The order of mechanical axis - axis pad - PCB board is the optimal solution for the feel. However, with the development of the times, the addition of the axis light has caused a light-transmitting hole to appear on the PCB board. Inevitably, the axis pad also needs to have a corresponding hole to allow the light to pass through, which also causes the key echo to spread out from this hole, causing the echo to become scattered and unfocused.

[0025] See also Figure 1As shown, the purpose of the utility model is to provide a beautiful sound pad for a keyboard, which includes a beautiful sound pad body 100, and in one embodiment, the setting position of the beautiful sound pad body 100 is improved. Compared with the setting sequence of IXPE shaft pad-PET plastic sheet-PCB board in the prior art, the improvement of this embodiment is that the beautiful sound pad body 100 is set above the keyboard shaft pad (that is, the beautiful sound pad body 100-IXPE shaft pad-PCB board).

[0026] In addition, an avoidance hole 110 is provided on the main body 100 of the sound pad, the purpose of which is to avoid the bottom of the mechanical axis and avoid the degradation of the key echo caused by the direct contact between the bottom of the mechanical axis and the main body 100 of the sound pad. After the bottom of the mechanical axis is installed in place, it can also prevent the bottom of the axis from contacting the main body 100 of the sound pad, resulting in friction noise caused by direct contact between the main body 100 of the sound pad and the keyboard PCB board.

[0027] In addition, a protrusion 111 extends from the lamp hole under the shaft to avoid the hole 110. The protrusion 111 is used to block the lamp hole, and the protrusion 111 is a light-transmitting layered structure, thereby blocking the lamp hole without affecting the light transmission of the shaft lamp, so as to solve the problem of the lamp hole deteriorating the keyboard sound.

[0028] Preferably, the overall contour of the avoidance hole 110 is adapted to the outer contour of the bottom of the mechanical axis of the keyboard, so as to avoid the position where the bottom of the mechanical axis contacts the pad under the axis.

[0029] Specifically, Figure 1 As shown, the avoidance hole 110 is in a "concave" shape when viewed from above, so that the protrusion 111 is directly formed on the main body 100 of the beautiful sound pad, so as to simplify the processing technology of the production of the beautiful sound pad main body 100, because the "concave" shaped avoidance hole 110 can be directly opened in the main body 100 of the beautiful sound pad, which also reduces the production cost, and the opening position of the "concave" shaped avoidance hole 110 corresponds to the bottom of the mechanical shaft, so as to avoid the position where the bottom of the mechanical shaft contacts the pad under the shaft, thereby achieving the above purpose.

[0030] The main body 100 of the sound pad is a soft transparent layer, which ensures that the light of the shaft lamp can pass through the protruding portion 111 normally.

[0031] More preferably, the sound pad body 100 is made of PET.

[0032] In order to effectively understand the difference between this case and the prior art, it is necessary to explain that:

[0033] It is considered that adding a very thin transparent PET plastic sheet between the PCB board and the shaft pad, and opening holes in the PET plastic sheet to avoid the mechanical shaft pins and then closing the lamp holes can alleviate the problem of echo dispersion. However, this solution has a disadvantage. When the mechanical shaft is installed, the actual contact sequence of the mechanical shaft is: shaft pad-PET plastic sheet-PCB board. Since PET itself is a plastic sheet, if only holes are set to avoid the mechanical shaft pins, then when the mechanical shaft is pressed, there will be a certain amount of sinking space in the shaft seat, which will cause friction between the PET plastic sheet and the PCB board, thereby generating a certain amount of plastic friction sound, resulting in the degradation of the echo.

[0034] In the specific implementation of this embodiment, a "concave"-shaped avoidance hole 110 is used. Due to the special shape of the hole, a protrusion 111 is formed to close only the lamp hole on the PCB board, and the contact position between the bottom of the mechanical shaft and the shaft pad is avoided. In this way, the lamp hole can be sealed to avoid the echo divergence while ensuring the perfect sequence of mechanical shaft-shaft pad-PCB board. At the same time, the upper and lower layers of the PET material of the beautiful sound pad body 100 are both soft sound-absorbing materials (that is, the upper and lower layers of the beautiful sound pad body 100 are provided with soft sound-absorbing layers), and pressing the mechanical shaft will not produce plastic friction sound.

[0035] It should be noted that the avoidance hole 110 is not limited to the "concave" shape. For example, the avoidance hole 110 is circular and concave on one side, which is approximately in the shape of the "concave" character. The specific selection here is based on the contour of the mechanical axis. It will not be exhaustive here, but it should be emphasized that the through holes opened in the beauty pad body 100 to avoid the mechanical axis in order to block the lamp hole are all within the protection range of the avoidance hole 110 in this embodiment.

[0036] Considering that the beautiful sound pad body 100 in this embodiment will be used on a keyboard, a keyboard is proposed, such as Figure 3 As shown, the keyboard includes a base 700, a top cover 200 is arranged on the top of the base 700, and a notch is provided on the top of the top cover 200 to expose the mechanical axis. After the base 700 and the top cover 200 are connected, an accommodation space is formed between the two, a PCB board is arranged in the accommodation space, a shaft pad is arranged above the PCB board, and a beautiful sound pad body 100 is arranged above the shaft pad;

[0037] like Figure 4 As shown, the mechanical shaft falls into the corresponding avoidance hole 110, and the pin passes through the shaft pad and is connected to the PCB board. The figure also shows the lamp hole (dashed line part), and then the protrusion 111 blocks the lamp hole. Figure 4 It is also not difficult to see that when the mechanical axis is pressed, its axis seat will have a certain sinking space, but with the opening of the avoidance hole 110, the axis seat avoids the sound pad body 100 and will not contact it.

[0038] The keyboard in this embodiment, specifically according to the principle of the mechanical keyboard, redesigned the PET plastic sheet, changed the order of placement, and changed it to PET plastic sheet (beautiful sound pad body 100)-IXPE shaft pad-PCB circuit board (PCB board), which solves the plastic friction sound caused by the key sinking. However, this brings another problem. If the PET plastic sheet is still opened only for the mechanical axis pin position as before, when the mechanical axis is installed, the bottom of the entire mechanical axis body will contact the PET plastic sheet, which has a great influence on the feel and sound. Therefore, we redesigned the opening form of the PET plastic sheet, using an opening in an approximate "concave" shape, which only closes the lamp hole on the PCB circuit board, and avoids the contact position between the mechanical axis and the IXPE shaft pad. In this way, while sealing the lamp hole to avoid echo divergence, the perfect order of mechanical axis-IXPE shaft pad-PCB circuit board is guaranteed.

[0039] Preferably, a bracket 300 and a partition 600 are respectively provided at the top and the bottom of the accommodating space.

[0040] In addition, an upper cushion pad 400 is disposed above the acoustic pad body 100 .

[0041] In addition, a lower buffer pad 500 is disposed under the PCB board.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model.
