description The invention relates to an infrasonic wave microphone, and belongs to the technical field of loudspeakers. The loudspeaker comprises a sound transmission frame body, a vibrating diaphragm and a pole plate are fixedly arranged in the sound transmission frame body, the vibrating diaphragm and the pole plate are oppositely arranged at intervals, a plurality of acoustic through holes are formed in the pole plate, a plurality of sliding parts are arranged on the pole plate in a sliding mode in the direction perpendicular to the pole plate, mounting bases are fixedly arranged on the pole plate, and the mounting bases correspond to the sliding parts one to one; a reset piece is arranged in each mounting seat, and each reset piece is used for driving each sliding piece to abut against the vibrating diaphragm so as to drive the vibrating diaphragm to move and reset in the direction away from the polar plate. When the infrasonic wave is tested, the diaphragm is vibrated by the external sound to change the distance bet
