Product details
Dayton Audio DAEX19SL-4 Slimline Coin Type 19mm Exciter 4W 4 Ohm
Dayton Audio's 19 mm DAEX19SL-4 coin type exciter features the same ability to turn nearly any surface into a speaker, as other exciters and tactile transducers, only in an extremely compact package for working with smaller surfaces in the minimum amount of space. This exciter's small size and weight enables audio reproduction in places never imagined: toys, signs, cabinet doors, etc... 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.
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.
A great field of application for this exciter is so-called DML or flat-panel speakers. DML stands for Distributed Mode Loudspeakers and is a term for speakers that catch the eye with their incredibly slim design.
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.
