Operating Instructions
1. Experiencing Bone Conduction Sound
The unique feature of the Blade Speaker is its ability to use bone conduction technology to turn various hollow surfaces into speakers. Experiment with different materials and objects to discover unique sound profiles.
- Wood: Provides rich bass resonance.
- Glass: Delivers medium to high frequencies.
- Drum/Hollow Objects: Produces ultra mega bass.
- Mirror: Offers clean and melodious sound.
- Cardboard/Kraft Box: Can provide varying sound effects.
