Abstract
A vibration membrane is disclosed. The vibration membrane includes a central dome part and a suspension part surrounding the dome part. The suspension part includes a pair of long-axis parts parallel to a long axis of the vibration membrane, a pair of short-axis parts parallel to a short axis of the vibration membrane, and a number of corner parts connecting the long-axis parts with the short-axis parts. The suspension part further includes first reinforcing parts located on the corner parts and second reinforcing parts located on the long-axis parts. Each of the second reinforcing part has a first master extension part and a first slave extension part crossing with the first master extension part. By virtue of the configuration, the strength of the vibration membrane is improved.
