Abstract
PURPOSE:To cancel wind noise components in the front face and the back face of a diaphragm by each other in an acoustic circuit by forming an acoustic path, which connects the back face of the diaphragm to the outside of a microphone main body, through a cut part, which is formed by cutting a part of a magnetic circuit, and a magnetic gap. CONSTITUTION:Magnetic circuit 21 is provided where magnetic gap 25 is formed between center pole 23 and yoke 24A. Acoustic pathes to connect back face 29a of dome part 29A of diaphragm 29 to aperture part 28 and connect back face 29b of edge part 28 to aperture 28 respectively are formed in parallel through cut part 26A provided in pole 23 of circuit 21 and cut part 26B provided in yoke 24A. As the result, in case that a rapid wind noise, etc., are incident onto microphone unit 20, the rapid sound applied to the front face of diaphragm 29 is given to dome part 29A of diaphragm 29 and back faces 29a and 29b of edge part 29B from respective acoustic pathes through aperture part 28 for dierctivity and is cancelled, and needless energy is not transferred to voice coil 34.
