Add audio to products and projects you never thought possible with the ultra-small Dayton Audio DAEX-9-4SM exciter. Measuring in at only 0.5" wide by 1" long and just 0.25" deep this exciter can fit almost anywhere. This exciter is also perfect for creating haptic feedback systems.
Key Features
• Extremely small design can fit almost anywhere
• Perfect for creating haptic (touch) feedback systems
• Unique suspension allows high excursion for surprisingly powerful response
• Rare-earth neodymium motor and a proprietary 9 mm voice coil
• 4-ohm impedance for use with small, Class D amplifiers
• Pre-applied 3M™ VHB™ adhesive for quick, durable installation
Dayton Audio's DAEX-9-4SM exciter will allow you to add audio or haptic (tactile) feedback to even the smallest projects. This 9 mm 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 amount 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 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 will be slightly quieter but result in a more full-range sound.
