  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.

  Surface Transducer - Medium
Surface transducers give you the awesome power to turn almost any surface into a speaker. They're 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. 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). * Impedance: 4ohms * Power: 3W * Dimensions: ø28mm x 27mm * Weight: 74g
