The suspension part is provided with pleat groups. The pleat group includes many pleats, and each pleats includes a first pattern section, a second pattern section, and a third pattern section connecting the first pattern section and the second pattern section. The height of the third pattern section along the vibration direction is smaller than the protrusion height of the first pattern section and the second pattern section along the vibration direction. The diaphragm of the present invention can be used to reduce low frequency distortion.
