Dynamic Exciters
Electrodynamic exciters employing coils and magnets that make full use of miniaturization technology and acoustic-related technology.
Point
- Attaches to solid object and vibrates it to make sound
- Excites multiple oscillation modes for wide directivity
- Easily becomes watertight as it needs no opening as sound outlet
- Rigid structure for robust circuitry
- Light and compact, yet gives high output
