  Surface Transducer - Small
Surface transducers give you the awesome power to turn almost any surface into a speaker. Much like our larger surface transducer, this is essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it against. You can hook it up to an audio source and press it against the nearest table, wall or cardboard box. You can even put it against your head and play music directly into your skull (the ultimate surround sound). * Dimensions: 21.5 x 14.5 x 7.9mm * Impedance: 8ohm ±5% * Resonant Frequency: 16kHz ±0.5 * Max Operating Voltage: 12Vpp * Frequency Response: 300 - 19000Hz * Rated input: 1.0 W * Operating Temperature: -20 to +60°C

  Geophone - SM-24
Need to put your finger on the pulse of the Earth? Did I just blow your mind? A geophone works by translating ground movement into voltage, which can easily be read by a microcontroller. The SM-24 geophone element is designed to offer the highest performance in seismic exploration based upon field-proven I/O Sensor technology. Low distortion, combined with excellent specifications, provide high-fidelity data. Basically, it's a super low frequency microphone for the ground. Perfect for all of your 2-D & 3-D seismic exploration needs with bandwidth from 10 Hz up to 240 Hz Tight specification, low-distortion geophone Extended spurious over 240 Hz, allowing full bandwidth at 2-ms sampling Sensitivity of 28.8 V/m/s
