Take your product or project to the next level by turning it into a
speaker! The DAEX25VT-4 is designed by Dayton Audio with voice coil cooling air
vents, for high-power applications.
Key Features
Small size; just over 2" diameter, about 7/8" high
Pre-applied 3M™ VHB™ adhesive for quick, secure installation
Rare-earth neodymium motor and a proprietary voice coil
4-ohm impedance for use with small, Class D amplifiers
20 watt RMS power handling for high output
Dayton Audio's 25 mm DAEX25VT-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 small size enables audio reproduction in places never imagined:
toys, monitors, cabinet doors... 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! 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. Thinner, smaller materials will
tend to be louder and create a mid/tweeter response. Thicker, larger materials
(with multiple exciters) will be slightly quieter but result in a more
full-range sound.
