It contains a small vibrating element that will output a few milllivolts peak-to-peak.\u003c\/p\u003e\n\u003cp\u003eYou will need an op-amp to amplify the signal, some chips are designed with the amplifier built in in which case you can wire it up directly.\u003c\/p\u003e\n\u003cp\u003eThis is an \"omnidirectional\" microphone, with -44dB sensitivity, and has 20-20KHz frequency response. You can plug it into a breadboard or perfboard or solder wires to the little wires sticking out the back.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/www.openmusiclabs.com\/learning\/sensors\/electret-microphones\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCheck out OpenMusicLab's great tutorial on Electret Microphones for a deeper look at how these sensors work\u003c\/a\u003e.
