Abstract
The present disclosure provides a vibration diaphragm. The vibration diaphragm includes a vibration dome; a suspension part surrounding the dome; and a reinforced part assembled with the dome. The reinforced part includes n pieces of longitudinal bar parts, a first transverse bar part and a second transverse bar part connecting ends of adjacent n pieces of the longitudinal bars respectively, and a third transverse bar part connecting n−1 pieces of longitudinal bar parts and located between the first transverse bar part and the second transverse bar part, where, n is an integer more than or equal to 3. The configuration of the reinforced ribs increases the surface area of the dome, and increases the width of the vibration frequency band of the vibration diaphragm.
