To better immerse you into the world of custom mechanical keyboards and detailing the process of sound dampening techniques, several themes will be touched upon. We start by exploring what mechanical keyboards are, the different types of switches, the science behind sound and vibration, the role of case materials and construction in sound production, and various sound dampening techniques. Lastly, we supply a step-by-step guide offering an accessible approach for beginners.
What are Mechanical Keyboards
Mechanical keyboards are distinguished from the typical membrane keyboards by the mechanical switches placed beneath each key. They provide a different tactile feel, responsiveness, and audio feedback, each varying depending on the type of switch employed.
Types of Mechanical Switches
Primarily, three sorts of mechanical switches exist: linear, tactile, and clicky. Linear switches, like Cherry MX Red, run smoothly without the tactile bump, providing an entirely smooth keystroke. Tactile switches, such as Cherry MX Brown, have a noticeable bump at the actuation point, providing physical feedback when the key has been pressed enough to register an input. Clicky switches, like Cherry MX Blue, produce a louder click sound upon actuation, alongside the tactile bump. This audible feedback helps typists know when they’ve sufficiently pressed the key.
Understanding Sound and Vibration in Mechanical Keyboards
In mechanical keyboards, the sounds mainly originate from the key switches, stabilizers, metal plate, and the keyboard case. When a key is tapped, the intricate mechanical switch underneath it moves. This switch movement triggers a series of vibrations that translate into sound waves. The type and intensity of the sound produced can depend on various factors like the switch used, the material and design of the keyboard case, and how the key has been pressed.
Role of Case Materials and Construction in Sound
The case of a mechanical keyboard functions as a resonance chamber, much like in musical instruments. The keyboard’s sound can be significantly influenced by the case design and the materials used. For example, plastic cases usually produce a higher pitched sound, whereas metal cases typically result in a lower pitched resonation. Construction-wise, tray mount keyboard design will sound different from a top mount or gasket mount because of the differing placements and number of contact points between the plate and the case.
Sound Dampening Techniques
Several sound dampening methods exist, mainly categorized as modding the switches, stabilizers, the space inside the case, or dampening the sound at the desk level. Let’s go into fine detail for each.
Modding the Switches and Stabilizers
-
Lubrication: Lubing the switches and stabilizers is an effective method to minimize friction points, resulting in a smoother keystroke and a quieter sound. Permatex Dielectric Grease or Krytox GPL 205 Grade 0 are the recommended lubes for stabilizers, while for the switches, Krytox GPL 105, TriboSys 3203 or 3204 are commonly used.
-
Film: Applying switch films can further help reduce rattling and enhance the sound. These can be used for both tactile and linear switches, but bear in mind that it might affect the clicky switches’ distinctive sound.
Dampening the Case
-
Foam: Case foam, plate foam, and shelf liner can be installed inside the keyboard case to absorb sound, thus reducing the reverberations and hollowness.
-
Silicone Mould: Another approach is to create a silicone mould to fit inside the case.
Desk-Level Dampening
Large desk mats made of neoprene or similar materials can absorb the keyboard sound, reducing vibration at the desk level.
A Step-by-Step Guide to Sound Dampen Your Mechanical Keyboards
Gather the necessary items: keycap puller, switches, lubes, switch film, case foam, and a desk mat.
-
Unscrew and open the case.
-
Remove the keys with the keycap puller.
-
Lube the switches and stabilizers. Ensure you get every contact point, but remember that “less is more” when it comes to lube.
-
Apply switch film to the switch housings, if desired.
-
Replace the keys.
-
Put case foam or your custom-made silicone mould into the case before screwing it back together.
-
Position the sound-dampened keyboard on top of a desk mat.
With these steps implemented, your mechanical keyboard will exhibit a quieter, more consistent, and enjoyable sound profile. Always remember, the sound dampening process is often subjective, and personal preferences vary widely. Experiment, adjust, and find what works best for your ears. It’s all part of the custom mechanical keyboard journey — as much an auditory endeavor as it is tactile.
