For mechanical keyboard enthusiasts, few things beat the satisfying “thock” sound of pressing high-quality keyboard switches mounted in a custom build. This unique audio/tactile experience comes from careful selection of keyboard parts and customization options. If you’re looking to build your own thocky keyboard packed with personality, read on for 7 methods to accomplish that goal.
Go Big on Keycaps
Keycaps make all the difference in amplifying a keyboard’s acoustic profile. Clacking plastic gives way to deeper, fuller thocks when you choose options made from materials like doubleshot PBT plastic or durable ABS caps. High-quality keyboard caps feature thick walls and special acoustic engineering, contributing to an overall thocky sound. Popular keycap profiles like SA, Cherry, and OEM affect sound; sculpted, contoured caps can direct the keypress noise down toward the base for maximum thock.
Lube Those Switches
The right mechanical keyboard switches make the foundation of a great thock. Tactile switches like Zealios or ERGO Clears offer an inherently resonant acoustic signature. But you can amplify the effect by meticulously lubing each switch manually. Use a switch opener to safely reveal the switch housing internals before applying a tiny drop of thick Krytox grease on the contact rails, avoiding the contact leaf and stem. This reduces friction and metallic “pinging” for a smoother, bassier keypress. Takes time, but a profoundly thocky reward awaits.
Experiment with Switch Films
Changing out the factory switch films for higher-end aftermarket offerings adds another opportunity to dampen switch noise for a deeper sound. Materials like polycarbonate or acrylic insert between the switch top and bottom housing, changing the acoustics. Some film options feature integrated switch-securing tabs to reduce wobble during activation. This tightens actuation for better thocking. Just a few dollars more per switch, but switch films make noticeable acoustic impact.
Modify Switch Springs
Finetuning a custom keyboard’s feel means experimenting with switch spring substitutions. Outemu, Durock, and other brands offer springs in different materials and “weights” measured by the grams of force needed to depress the key. Heavier springs typically create a lower-pitched keypress sound with more substantive thocking. Just make sure to get the right spring length for your switches. Changing out a few springs on commonly used keys can also create an interesting sound profile across the board.
Install Case and Plate Foam
Open up any prebuilt mechanical keyboard and you’ll likely find empty space inside the plastic case that generates bothersome echo and ringing. Use adhesive-backed sheets of sound-dampening EVA foam to line the bottom and sides of the case interior to absorb stray noise. Plate foam reinforces this effect from underneath the PCB mounting plate for thockier keystrokes. Effective foam mods cost around $15-20 for custom keyboard builds under $100. Peel-and-stick application requires no permanent modifications.
Choose a Thocky Keyboard Case
Metal and dense polycarbonate keyboards transmit more pleasing acoustic energy compared to cheap ABS plastic cases which can impede thocks. Popular community case designs from makers like GoblinTechKeys emphasize steel and aluminum to allow the full sound profile to resonate. Small, compact cases without hollow empty spaces also promote powerfully resonant thocking. Just make sure to test case construction materials when planning builds, as strong metals can have a high-pitched ring. Multi-layer polycarbonate hits the acoustic sweet spot for many thock fans.
Apply Tactile Tape Mods
Looking to add some extra thock to an existing off-the-shelf keyboard? Simple tactile tape mods provide noticeable acoustic impact for just a few dollars. Vinyl tactile bumpons applied to the underside of the PCB can help absorb sound while allowing switch force to transmit through keys. Foam tape also sticks PCBs more securely to the case, reducing noise leaks from board flexing. Dense rubber shelf liner placed inside keyboards brackets sound while adding mass for greater thock. Get creative blending tape mods with other acoustic tweaks without any permanent changes.
Experiment with all these inexpensive but high-impact customizations and you’ll be thocking in mechanical keyboard paradise in no time. Heavier keypresses, more rounded sound character, and addictive keyboard ASMR awaits. Which methods worked best to give your custom keyboard that ideal thock?
