Summary:A condenser microphone comprises a substrate, a vibratile diaphragm and a back plate. The substrate has an opening. The diaphragm is disposed corresponding to the substrate and covers the opening, and has a plurality of protrusions. The back plate is coupled to the diaphragm and has a plurality of through holes, at least some of which are corresponding to the protrusions respectively. An interval is formed between the diaphragm and the back plate, and when the diaphragm vibrates, the protrusions move into or further near the through holes.
