SparkFun Electret Microphone Breakout 駐極體麥克風放大模組 美國 SparkFun 原裝進口
個小型分線板將一個駐極體麥克風（100Hz-10kHz）與一個60x麥克風前置放大器連接起來，放大聲音，拍手，門鈴或任何足夠大的聲音，以便被微控制器的模數轉換器拾取。每個Breakout都完全組裝和工作從2.7V至5.5V。通過捕捉麥克風中的兩個導電板（一個振動膜片和另一個固定的）之間的聲波並將它們轉換成電波，駐極體麥克風Breakout轉換振幅（而不是音量）。這些電信號然後被放大並由微控制器的ADC拾取。

SparkFun Electret Microphone Breakout
This small breakout board couples an Electret microphone (100Hz–10kHz) 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 microcontroller’s 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 microcontroller’s ADC. Get Started With the Electret Microphone Guide!
