Dayton Audio’s DAEX25FHE-4 sound exciter adds dynamic sound to almost any object or surface.
- Just under 2″ diameter, about 7/8″ high
- Quick, durable installation with Pre-applied 3M™ VHB™ adhesive
- Rare-earth neodymium motor and a proprietary voice coil
- 4 ohms impedance for use with small, Class D amplifiers
- high output with 24 watt RMS power handling
Dayton Audio’s 25 mm DAEX25FHE-4 coin type exciter features the same ability to turn nearly any surface into a speaker, as other exciters and tactile transducers, only in a more compact package for working with smaller surfaces. This exciter’s compact size allows audio reproduction in places never imagined: toys, monitors, cabinet doors and even windows.
A neodymium magnet is employed to create maximum magnetic flux around the proprietary voice coil for increased sensitivity when compared to similar sized exciters. In turn, this reduces power requirements and makes it possible to use very small audio amplifiers, without sacrificing total output. The 1″ voice coil, and cooling vents, allows for more input power for higher output applications while maintaining a slim-line form factor.
To ensure maximum acoustic energy transfer between the transducer and the surface to which it is attached, 3M VHB (Very High Bond) adhesive is pre-applied. Just peel and stick. Four screw tabs are also provided to support the weight of the exciter, for permanent inverted mounting (or when mounting on moving surfaces). Two PCB solder points keep installation and wiring as compact as possible.
Note: An exciter’s frequency response and sensitivity are completely dependent on the exciter’s designated surface. Larger, thicker materials (with multiple exciters) will be slightly quieter but result in a more full-range sound. Smaller, thinner materials will tend to be louder and create a mid/tweeter response
