This exciter packs a punch in its tiny frame. Dayton Audio’s DAEX19SL-4 4 ohm sound exciter can make most light, rigid surfaces into a speaker with a surprising amount of output. It’s perfect for adding audio to signs, small toys, and many other projects.

Product Highlights

• Dual suspension for lower distortion and linear operation

• Pre-applied 3M™ VHB™ adhesive for quick, durable installation

• Can be installed almost anywhere (only 1.3″ diameter by 0.26″ high)

• 4 ohms impedance for use with small, Class D amplifiers

Product Description

Dayton Audio’s 19 mm DAEX19SL-4 coin type exciter has the same ability to turn nearly any surface into a speaker, as other exciters and tactile transducers, only in an incredibly compact package for working with smaller surfaces in a minimum amount of space. This exciter’s small size and light weight enables audio reproduction in places never imagined: toys, signs, cabinet doors, etc 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.
3M VHB (Very High Bond) adhesive is pre-applied,  just peel and stick. This will ensure maximum acoustic energy transfer between the transducer and the surface to which it is attached. 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 surface the exciter is on. When placed on smaller and thinner materials the exciter will tend to be louder and create a mid/tweeter response. Larger and thicker materials (with multiple exciters) will be slightly quieter but result in a more full-range sound.
