#keybored Aerospace Engineer Explains Mechanical Keyboards
So... Throughout the year, I have force-fed my viewers physics, thinly disguised as a "keyboard video." Surprisingly, many of you guys actually liked the science content, and wanted them all combined into 1 "MASTER" video, so you can torture yourselves... or for those nights you can't fall asleep. I did just that. I hope you enjoy the compilation!

@cyanotypes Год назад

love the scientific approach to the keyboard hobby! thanks for taking the time to make this have you seen Blacksimon's Keyboard Science spreadsheet? it's more anecdotal but it has a bunch of sound effects of different components (switch material, weight placement, case tightness, etc.)

@philipp594 Год назад

The natural frequency also depends on the geometry of the object. Luckily those will most likely be the same in the same keyboard model.

@Lishtenbird Год назад

Knowing the basics, I felt something was "wrong" in the slide at 20:05 - it's been bugging me, and I think now I got why. The slide says that 1) thin foam is used to reduce higher frequencies, and 2) thick foam is used to reduce lower frequencies. The wording makes it look like in both cases, it's used to filter out _only_ those specific frequencies. What it actually means is that 1) thin foam will reduce higher frequencies, while 2) thick foam will reduce higher frequencies _and also_ lower frequencies (as the NRC chart earlier shows), except those we actually may want to let through because we like them. If we mute both, we mostly leave the rest of unfoamed parts speak, which will change the sound a lot, likely not for the better. Some may say that's nitpicky and it was evident/explained well enough in this video and the Thock one, but I know I stumbled on this part both times, so I think the clarification at least won't hurt.

What counts as "thin" foam and "thick" foam? For example QK75 has case, plate, PE foam. Are you saying all 3 together would be considered thick, 1 foam would be thin?

@breadles5 Год назад

i just wanted to ask, what physical properties of ABS or PBT that make keycaps sound higher or lower?

@stobe187 Год назад

PBT keycaps are usually thicker, which produces a lower sound

@ethur10n Год назад

but generally PBT isn’t as dense as something like Vintage Cherry/GMK because they’re typically dye-subbed and the double-shots actually make the construction more dense. Consensus according to chyrosran22: -thicker caps are deeper but muted -abs is deeper than pbt -taller caps are deeper My observations: -PU and POM are the deepest keycap material -thick, but roomy case resonates the bassiest sounds -if switches bottom out with a lot of surface area, it is deeper (which is why Alps SKCM/SKCL, Dome with Sliders, and Fujitsu Leaf Spring are deep sounding while Long Stem Cherry MX switches are higher)

@JustFluxz 4 месяца назад

in practice, how much stiffer does pom plates feel compared to PC?. also how much thockier is PC sound compared to pom? I generally prefer thockier sound but also prefer the feel of stiffer plates. Also to confirm, nonflex pcbs will have more thock over the flex pcbs? I would have thought the flex pcbs would have more thock due to being less stiff. I am trying to decide on getting a QK75N but unsure which pcb and plate to get.

@mashygreen6974 Год назад

Amazing and very informative video! The only thing I kinda felt was missing is explaining a bit more the mechanical wave’s origin in terms of pressure and how pressure and more emphasis on the concept of energy conservation. But then, as a fellow aeronautical engineer, albeit from a fluid dynamics perspective, I’m more than a bit biased to seeing no everything in terms of fluids and energy conservation. 😅 Other than that this the best ‘physics for keyboards’ I have seem! Well done.

@Hans256xD Год назад

bruh you redid the plate portion and still kept the wrong youngs modulus for carbon fiber in the chart, the HT fiber Composite used in your standard keyboard plate is around 100GPa as UD and more around 65GPa as a woven Fabric that is usually used for such Carbon fiber Plates, the fiber alone is of course stiffer but in the case of a plate you have to look at the composite structure, so fiber+resin

Keyboard makers when watching this video; -So we didnt need to throw random cheap together 50 times and we could of used maths so calculate the sound? * Suprised pikachu face *

@joeno9631 Год назад

Thanks for this nice video. When you tested the case sound of the bare aluminum case vs. aluminum + steel weight i think it was the same case. So the bare case had just air, where in the other case the steel weight is placed. So do you think if the steel weight is replaced with a alu weight, would they sound the same, especially the complete build keyboard? Because the specific stiffness of steel and alu is very similar as shown by you, with alu slightly more to the "thockier" side.

@MrSkullface Год назад

I have a question that I would love to maybe see a video of. Exactly what does actuating switches do to the durability of the switch. Also something like polishing the rails correctly with a Dremel or something. And if you are smoothing switches its that only good for the parts that are being smoothed since its basically just matching grooves to slide easier vs something like real polishing. Also what about residue from all the actuation.

@klemenshiller6379 Год назад

The ultimate thocc mod is to just take off the bottom case with the PCB straight on your bed or some foam. Unfortunately though this mod is really just a fast way to brick the keyboard :/

@MonkeyNeuronActivation Год назад

17:39 I don't think the frequency of a sound wave affects the speed of wave? Or do you mean the moving speed of each molecule of the medium?

@victor_glekler Год назад

So if the case is like the one of sound speakers, will the bass reflex tube in the case make the bass of the structure borne sound louder?

@philipp594 Год назад

So brass sounds higher because it is so stiff it transfers more vibrations to the case? Or everyone is just wrong and brass sounds deeper in a built keyboard?

@pirateradioFPV Год назад

So guess next we need a keyboard reflex port calculator for that ultimate thock 😂

You said that more foam or stacks of foam provides less thock and thin foam provides more thock, so does that mean the thinner the Pe foam the more thock and the thicker the Pe form the less thock?
