  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
  Breakout Board for Electret Microphone with op-amp
This small breakout board couples an Electret microphone (100Hz10kHz) with a 60x mic preamplifier to amplify the sounds of voice, claps, door knocks or any sounds loud enough to be picked up by a microcontrollers analog-to-digital converter. Each breakout comes fully assembled and works from 2.7V up to 5.5V.The Electret Mic Breakout translates amplitude (not volume) by capturing sound waves between two conducting plates (one a vibrating diaphragm and the other fixed) in the microphone and converting them into electrical waves. These electrical signals are then amplified and picked up by your microcontrollers ADC.
  Piezo element ø12mm 7BB-12-9
Piezo element that can be used either to play sound or in reverse, to pick up sound / vibrations Extremly low build height. Requires external oscillator. When used to pick up sound, it's usually called a contact microphone. Resonant frequency: 9 kHz ±1kHz Impedance: 1k @ 9kHz Diameter: 12mm Thickness: 0.22mm
  Piezo element ø35mm 7BB-35-3
Piezo element that can be used either to play sound or in reverse, to pick up sound / vibrations Extremly low build height. Requires external oscillator. When used to pick up sound, it's usually called a contact microphone. Resonant frequency: 2.8 kHz ± 500 Hz Impedance: 200 ohm @ 2.8 kHz Diameter: 35 mm Height: 0.53 mm
  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
  Piezo element ø20mm with wires
20mm piezo element with pre-mounted load resistor and cables with pins. Ready to use as a speaker or sensor. Can be used to detect foot steps, knocks, drums and much more!
