Understanding Cherry MX Switches and Sound Profiles

by

Building a custom keyboard with Cherry MX switches offers a unique opportunity to tailor the sound profile to your preferences. Whether you prefer a clicky, thocky, or quiet typing experience, tuning the sound profile can significantly enhance your typing satisfaction. Here are some practical tips to help you achieve the perfect sound profile for your Cherry MX switch keyboard build.

Understanding Cherry MX Switches and Sound Profiles

Cherry MX switches come in various types, each producing a different sound and feel. For example, Cherry MX Blue switches are known for their clicky sound, while Cherry MX Red switches tend to be quieter and smoother. The sound profile of your keyboard is influenced by the switch type, keycap material, case construction, and damping materials used.

Key Factors Influencing Sound Profile

  • Switch Type: Determines the inherent sound and feedback.
  • Keycap Material: ABS keycaps are louder than PBT.
  • Case Material and Construction: Metal cases produce more noise, while foam dampening can reduce it.
  • Lubrication: Applying lubricant to switches can smoothen keystrokes and reduce noise.
  • Dampening Materials: O-rings, foam, and damping pads can absorb sound and reduce reverberation.

Sound Profile Tuning Tips

1. Choose the Right Switches

Select switches that match your desired sound profile. For a clicky sound, Cherry MX Blue or Green are ideal. For a softer, muted sound, Cherry MX Red or Silent variants are better options.

2. Use Damping Materials

Apply damping materials such as foam inside the case or under the PCB. O-rings on keycaps can also reduce bottom-out noise, creating a softer sound.

3. Lubricate Your Switches

Lubricating switches with appropriate lubricants can decrease friction and noise. Be sure to use lubricants suitable for mechanical switches and follow proper application techniques.

4. Select Appropriate Keycaps

Opt for PBT keycaps over ABS for a deeper, less resonant sound. Thicker keycaps tend to produce a more subdued sound profile.

5. Adjust Case and Mounting Style

Using a case with sound-dampening features or mounting the PCB with silicone or foam can significantly alter the sound. Consider different case materials like wood or acrylic for unique acoustic properties.

Experiment and Personalize

Sound tuning is a highly personal process. Experiment with different combinations of switches, keycaps, dampening materials, and case setups. Record your preferred configurations to replicate your ideal sound profile in future builds.

Conclusion

Achieving the perfect sound profile for your Cherry MX switch keyboard build involves understanding the factors that influence acoustics and applying targeted modifications. With patience and experimentation, you can craft a keyboard that not only feels great but also sounds exactly how you want it to.
