Electret Microphone Breakout 駐極體 麥克風 放大模組 sparkfun原裝代理進口

這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，拍子，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。 每個突破都是完全組裝的，工作電壓從2.7V到5.5V。

駐極體麥克風放大模組通過捕捉麥克風中兩個導電板（一個振動膜片和另一個固定的）之間的聲波並將它們轉換為電波來轉換振幅（而非音量）。 這些電信號然後被放大並由微控制器的ADC拾取。

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.
