Quick Overview Take your product or project to the next level by turning into a speaker! The DAEX13CT-8 sound exciter, by Dayton Audio, is designed to turn small surfaces into a hidden sound source. Product Highlights Super small size; just over an inch in diameter, about 3/8" high Pre-applied 3M™ VHB™ adhesive for quick, durable installation Rare-earth neodymium motor 8 ohms impedance for use with small, Class D amplifiers Product Manuals / Spec Sheets / Downloads Dayton Audio DAEX13CT-8 Specification Sheet AddThis Sharing Buttons Share to FacebookFacebook Share to TwitterTwitter Share to MoreAddThis 2 Product Description Dayton Audios 13 mm DAEX13CT-8 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 exciters 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 8-ohm nominal impedance facilitates the use of parallel 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 exciters frequency response and sensitivity are completely dependent on the exciters 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.
