Some embodiments of the present invention provide miniature sounder which includes a frame and a vibration system and a magnetic path system fixedly connected to the frame. The magnetic path system includes a lower clamping board, a primary magnet disposed on the lower clamping board, secondary magnets disposed on the lower clamping board and arranged around the primary magnet, and a cushion provided on the lower clamping board and located outside the secondary magnets, a gap being provided between two adjacent secondary magnets. The vibration system includes a voice diaphragm, a voice coil which drives the voice diaphragm to vibrate and generate a sound, and a vibrating diaphragm which elastically supports the voice coil. The vibrating diaphragm includes a first connecting portion connected to the voice coil, a second connecting portion connected to the cushion, and a corrugated rim connecting the first connecting portion and the second connecting portion.
