Custom Enclosure Design Recommendations
If youβre designing your own enclosure, here are some important guidelines to ensure optimal audio performance:
- Ensure that the distance between the speaker and the two microphones is uniform, and minimize the transmission of speaker vibrations to the microphones to maintain audio clarity.
- The enclosure should allow human voice to reach each microphone without obstruction, ensuring direct sound (as opposed to reflected sound) can evenly reach both microphones for accurate sound capture.
- If you are designing a sealed microphone chamber, avoid creating a resonant cavity that is narrow at both ends and wide in the middle, as this can interfere with front-end signal processing. If a sealed chamber is not feasible, incorporate multiple perforations in the enclosure to prevent sound reflections from bouncing inside before reaching the microphones. This helps to maintain signal integrity.
Beginner Tips for Easier Soldering
For beginners, we recommend using pin headers when soldering components. This makes the process smoother and helps reduce errorsβperfect for those just getting started.
