Take your product or project to the next level by turning it into a
speaker! The DAEX9CT-4 is the smallest of the Dayton Audio Exciters and is
designed to turn small surfaces into a hidden sound source.
Key Features
Super small size; less than an inch in diameter, less than 3/8" high
4-ohm impedance for use with small, Class D amplifiers
Turns almost any surface into a speaker
Pre-applied 3M™ VHB™ adhesive for quick, secure installation
Rare-earth neodymium motor
Dayton Audio's 9 mm DAEX9CT-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 extremely 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. Its 4-ohm nominal
impedance facilitates the use of series and series-parallel wired arrays for a
highly focused, minimum dispersion sound pattern.
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.
