Abstract
The present disclosure provides a vibration diaphragm. The vibration diaphragm includes a vibration part; a suspension extending from and surrounding the vibration part; and a pattern module part formed on the vibration part. The pattern module part includes a ring-shaped first protrusion, and at least two second protrusions bounded by the ring-shaped first protrusion. The second protrusions each has two ends connected to the ring-shaped first protrusion. By virtue of the configuration of the pattern module part, the solution described by the present embodiment increases the surface area of the vibration part, and widens the bandwidth of the vibration diaphragm, and further improves the acoustic performance of the diaphragm.
