Take any project or product to the next level by turning into a speaker. The Dayton Audio DAEX19CT-4 sound exciter features voice coil vent holes for higher power handling.
• Strategically-placed vent holes cool this exciter’s voice coil for higher power handling
• Rare-earth neodymium motor with cooling vents for higher power handling
• 4 ohms impedance for use with small, Class D amplifiers
• Small size; just under 1-1/2″ diameter, about 3/8″ high
• Pre-applied 3M™ VHB™ adhesive for quick, durable installation
Dayton Audio’s 19 mm DAEX19CT-4 coin type exciter can 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 before like 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. This reduces power requirements and makes it possible to use very small audio amplifiers, without sacrificing total output. Cooling holes placed strategically on this exciter’s housing allows for higher power handling, for applications where more output is desired, while maintaining a small form factor.
To make sure there is 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. Smaller, thinner materials will tend to be louder and create a mid/tweeter response. Larger, thicker materials (with multiple exciters) will be slightly quieter but result in a more full-range sound.
