The 9 mm DAEX-9-4SM exciter is an ideal option when designing pocket sized personal speakers or for adding audio to small art projects and models. At only 0.5" wide by 1" long, this exciter is even perfect for use in virtual reality haptic feedback systems such as gloves and headsets. 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. The unique suspension is capable of high physical excursion to allow this extremely small and lightweight exciter to deliver an impressive a of force while remaining linear. 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.
