Patent attributes
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 protrusion extending outwardly from the vibration part and having a groove recessed inwardly toward the vibration part; a partition dividing the groove into at least two rooms; and a second protrusion located in each of the rooms. 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.
