## Description

Turn a table, wall, cardboard box or other flat surface into a speaker with this large surface transducer. Instead of using a traditional cone, the coil is attached to a pad that transfers vibration directly into the surface it is pressed against.Connect it to an audio source and experiment with different materials to hear how each one changes the sound. It is a handy part for interactive installations, custom enclosures, props, exhibits and audio experiments where a normal speaker cone is not ideal.The pack includes one transducer, one screw-on base and one adhesive magnet that can be attached to the base for convenient mounting.Specifications:Dimensions: 50mm Diameter, 31mm TallWeight: 0.51526 lbs.Power: Nominal input 10 W, Maximum input 25WNominal Impedance: 4Ω±15% test@200Hz1vLowest Resonance Frequency: 58Hz±20% (@ 1.0 V)Output Sound Pressure Level: 85±3 dB(100、400、800、12000Hz medium value @1m 10w)Distortion: 5% less @ 5W 1000HzGreat for makers experimenting with hidden speakers, vibration audio and unusual sound-producing surfaces.
