The diaphragm body part includes a rigid dome part, a silicon rubber membrane, and a plastic support engaged to an edge of the silicon rubber membrane. The dome part is engaged at a middle position of the silicon rubber membrane. A convex or concave bent ring part is provided at a location at an outer side of the dome part on the silicon rubber membrane. A spacing between the edge at an outer side of the dome part and an edge of the bent ring part closer to the dome part is in a range of 0.02 mm and 0.2 mm, and colloid is disposed in a gap between the dome part and the bent ring part. The loudspeaker vibration system according to the present disclosure may improve product sensitivity, reduce distortion and enhance acoustic performance of the product.
