Abstract:
A microphone includes: a substrate including a tone hole and having a top surface on which a substrate electrode is provided; a converter provided on the top surface of the substrate and including a main body having a back space, a diaphragm provided at the bottom of the back space of the main body, and a converter electrode provided on a region of a bottom surface of the main body facing the substrate electrode; and a bump connecting the substrate electrode and the converter electrode to each other. The diaphragm vibrates in response to sound entering from the tone hole. The converter converts sound into a signal.
