CZ034GU Electret Microphone Electrical Wire These are Metal Film ResistorThis is a unidirectional electret microphone with high sensitivity. Audio recording, voice recognition, and other audio sensing projects circuits use this microphone. Long lasting metal body and high quality diaphragm for consistent audio sensing. Electret Condenser Microphone is a type of electrostatic capacitor based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material. An electret is a stable
