{"title":"Electret Microphone - 20Hz-20KHz Omnidirectional","handle":"electret-microphone-20hz-20khz-omnidirectional","url":"/products/electret-microphone-20hz-20khz-omnidirectional","description":"\n     This electret capsule microphone is the same one we use in our great microphone amplifier board. It contains a small vibrating element that will output a few milllivolts peak-to-peak. You 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.This 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.Check out OpenMusicLab's great tutorial on Electret Microphones for a deeper look at how these sensors work. If you need an amplifier board, see our fully-assembled and tested mic amp board with adjustable gain. \n\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[{"name":"Title","values":["Default Title"]}],"variants":[{"id":15421,"title":"Default Title","sku":"AF-1064","price":2.92,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
